D90 Power Brake Bleeder

May 5th, 2008

To make bleeding a one man job, you should check out a pressure bleeder (get the Euro version with the 1100 adapter):

http://www.motiveproducts.com/index.html

It makes bleeding the clutch or the brakes so much easier - I do it myself all the time. Also, I use to flush the fluid in my clutch periodically to help it last a little longer, and hopefully prevent having to go through that whole process again. Can’t say for sure how much that helped, but I never had a problem after that initial repair for many years.

Flex-a-lite 220

Replace A/C thermostat with the VW fan switch (Beck/Arnley 201-0809)

Put a piece of 2×4 under the bottom tabs of the radiator and bend/beat them flat. Then rivet a piece of 1×1 aluminum angle to the bottom. Use a 2×2 aluminum angle to make the top mount.

Use 2″ angle for mounting brackets.

D90 Oil Cooler Pressure Sender Adapter

November 11th, 2007

Does anyone have an online source for the 5 - 1/8 F50G-S Adapter fitting from Parker Hydraulics?
Thanks.

I got mine from http://www.cincinnatihose.com/

I bought my #5 o-ring boss to 1/4″ NTP adapter from Capitol Bearing, www.capitolbearing.com, in Round Rock. Then I bought a 1/4″ to 1/8″ bushing. The part number for the straight adapter is 2216-4-5s. The FAQ indicates they will ship parts.

D90 Hard Top Installation

November 1st, 2007

All you have to do is remove all of the front and interior roll cages…T45 and T50 torx bits…then there is an aluminum plate on top of the windscreen which has 6 (I think) phillips head 6mm screws holding it in…replace these phillips head things with hex head 6mm bolts (1″ should do fine) there are nutserts in there…this bolts the top to the windscreen…on my 95 there were nutserts in the top edge of the rear tub…I did a prelim set up with the sides and measured where the nutsert holes were and drill through the bottom edge of the side panels…then tentatively loosely mounted the sides onto the rear tub…mounted the top loosely and then kind of forced everything to line up…don’t forget there are rubber seals between the sides and the tub, the sides and the top and the fron of the top and the windscreen…when all looks good, tighten down and you’re done except for mounting the rear liftgate…I would have mounted the station wagen front cage but the one I bought was bent and unusable so am running without it. My original ex-MOD soft top which I converted to hard top was run without a roll cage too…
George
ps
just to be clear, you do not need to drill holes into the rear bed/tub or windshield…just into the hardtop sides. I used 1/4-20 bolts/nuts to bolt the top to the sides. the rear tub nutserts take 6mm bolts…I used 2″ long ones. and further clarification the rear roll cage is totally not usable with the Euro spec hard top.

——

The POE top is actually easy to put on with two people. Ron and I put my POE top on, and tightened it down so it would stay on for my 2 hour drive home. later that week i took the time to take it off again and wash it out and i put a seal on the windshield and then drilled two holes right under where the top of the seatbeat hooks in. 1 hole on each side of the tub. there are these brackets that pull the top down for a snug fit to the tub. other that that those were the only two holes. I also got 6 #6 metric bolts about an inch long and stacked about 3 washers on them and bolts the front of the top to the windshield. you need these 3 washers to insure that you can get a wrench in there to get them undone later when you want the top off. trust me its a tight fit if you dont!!!

I do wish my tailgate matched up better with the rear window. I have about a 1/4 gap between them. but other than that i love my POE top

George do you have this gap there too? I cut a door seal and put it on the window side of the top so that my gap is a bit smaller. is there anyway to close it up to “seal” it?

D90 Liftgate Installation

November 1st, 2007

For mounting the liftgate, I drilled the rear of the top to attach the series liftgate hinges and used button head hex bolts for a smoother, rivet-like appearance. I also removed the rear washer jet and plugged it using another identical bolt. Two 30-pound gas struts were required to support the lift gate (I didnt want to use the original series prop-rods) and the brackets are stainless ones which seemed the proper shape. All the gas-strut stuff was sourced from McMaster-Carr. Since I had a used, imperfect headliner, I didnt feel bad cutting it to accomodate the hinges.

——

Here are the pictures you requested. I’ll email a larger format to you also. just thought I’d post here in case anyone is also interested.

The gate is locked shut by a flange at the bottom of the gate that tucks behind the tailgate when closed. Because of this the T-handle is not necessary. The hole in the gate for the locking T-handle is covered by a LR badge that is stuck on by glue / tape. I think you can get them at R.N.

More pictures here.

The brackets are stainless stuff from McMaster.

One thing that worked out was that the triangular shape of the lower brackets made a perfect surface for the locking rods to grip. When the gate is closed, you turn the handle and the pegs extend out and engage the angled side. It worked out to be just right to squeeze the seal and hold the gate in the right position when closed. The seal is compressed enough that nothing rattles.

More pictures here.
——

Randy- are you using the lift gate in normal series configuration? i.e where a drop-down tailgate closes first and then the lift gate closes second? Also, what came on your lift gate? Was it stripped? The stock set up is a strip that rivets to the outside bottom edge, and a seal retained by a metal strip that rivets to the inside bottom edge of the lift gate.

If you want the stock series parts you can have them cheap (I’ll have to have my wife hunt around for them, they’re back at home). I couldnt use them since the NAS tailgate must be closed after the lift gate because of the tire carrier and brake light bar. I bought a piece of LR weatherstripping that looked like it would work, I’d have to check the part number if you wanted that.

I also have the series prop rods you were asking George about if you want them so you dont have to use gas struts. I looked at both options and went with the gas struts - much easier.

The gas struts are 2x 9416K2 in the 30lb strength
I used 4x 9416K86 M6 nylon ball socket fittings
2x 9512K12 304 stainless ball brackets
and 1x each (left and right) 9512K16 and 9512K17

Note that each of the parts are available in a variety of materials. You can even get 100% marine grade stainless gas struts for 75 bucks each. I went the economical route except for the brackets which are much nicer in stainless. The nylon ball joint sockets cost like 1/8 of the stainless and I figure will resist rust at least as well

I used a 332564 for the seal. It think its a series rear door seal of some kind. Got it from George.

—–

My seal is simple and effective - it is made with a thin metal retainer - a strip of 1/2″ wide 1/8″ thick annodized aluminum - from the hardware store and a piece of garage door bottom seal -(dense foam strip with abrasion resistance) I chose that seal because it is chemically engineered to withstand UV radiation. Mine has worked quite well over the past few years. I will post some picks of it for you this evening. It is very simple to attach - I used the series of holes that are already in bottom of the lift gate to attachethe unit with small SS machine screws.

More pictures here.
——

The hinge (large u shaped thingy) is the same part POE to 1960s Series truck.
The bracket that bolts to the roof on a POE is different than a Series rig, but both will work. A little shaping and the Series Rover one will rivet right in, or you can make a simple corss bolt bracket just like the POE unit.
The set up I used was a 1960s Series liftgate with 1960s hardware and some gas struts from NAPA.
Then added a small steel piece at the bottom of the liftegate to have a seal surtface between the tailgate and the liftagte.
I made the glass bigger though to match the side galss and give a better rear view.

——

I did a very similar thing a while back. Got the parts from Canada off a parts series truck… the hinge brackets needed a little choppling to make fit properly but it was really easy.. then as mike said rivit in and you have a liftgate.

One thing that was tricky was getting the spacing for the seal right. But it was not that big of a deal, just took some planning… good luck!!

——

I got the brackets from Rovers North…I’m attaching two pix to show the cuts I decided to make on the brackets…once cut like this and excess metal bent out of the way (too lazy to cut and trim!) they slide right in…there is a right and left to the brackets…I bolted the hinges to the rear door first then hung the door on the lip of the upper edge of the opening and made sure it was centered…then I marked where the hinges lined up left and right…then I positioned the brackets, marked the rivet holes…drilled and riveted in place…the pins for the brackets (must be ordered as they don’t come with the brackets are weird…one of them was too big so dry test em first…also see 3rd pic of completed do-it-yourself POE liftgated soft top to hard top conversion…man it was cold without that liftgate…I really prefer the liftgate idea to a door because you can drive with lumber sticking out the back with the liftgate open…also great rain shield while standing out in weather.

More pictures here.
——

I’m not sure how the liftgate is configured, but the f-glass lift gate has a flange along its bottom edge that prevents the liftgate from opening when the tailgate is closed. A piece of weatherstripping attaches to this flange and presses against the top of the inside face of the tailgate creating a seal. It would seem a simple matter to take an L-shaped piece of aluminum and screw it to the bottom of the POE liftgate to replicate this flange, then attach a piece of weather stripping to the flange and be all set up.

——

In the POE configuration, you don’t use all the Series locks and handles etc (also, I can’t remember how the Series liftgate used to work on my old Series IIa)…I removed all that stuff and am mounting a 3″ metal strip on the inside bottom edge of the liftgate which will have a piece of the weather seal (that goes around the rear opening) on it…the tailgate will lock and keep the liftgate closed. All I have to do now is figure out how to mount two gas struts and where to source the struts and their mounting brackets…any suggestions are welcome.

D90 Power Steering Leak

October 13th, 2007

If it is a small one, u can add a bottle of lucas PS stop leak to help it out.

I do not recoment the seal kit it usaully does not work, The output shaft is usaully bent that is why it leaks. Just replace the whole box and save yourself the headaches

Try a tablespoon of brake fluid. I tried Lucas, still leaked (although less), the brake fluid stopped it completely. Amazing but it worked.

D90 Radiator

September 8th, 2007

I can have it recored to five core R-fin. Like I do for my diesels. If you want the very best. It will cost over 600 plus shipping.

I can have it built without oil cooler. This radiator would give 40 percent more cooling capacity.

Motor mounts

August 24th, 2007

I went through the whole motor mount saga with my 5 liter, breaking mounts on two Nevada Trophy events and elsewhere.

1. I’m currently using land rover diesel mounts, got them from British Pacific, and very happy with them. They are square and much heavier duty. Haven’t broken one yet.
2. I tried the QTs. IMHO, only for competition — they are way too stiff and the whole truck vibrated excessively, too much for me.
3. During the time that I was breaking stock mounts, the passenger side exhaust was kicking the frame on decelration. I’m sure that had something to do with it. Part of the drive train issue.

I’d just try the diesel mounts first and see if they last a few months.

D90 SW door install on ST

July 24th, 2007

A few comments so far on the install:
1 - I needed longer bolts for the nader pin assembly
2 - The bar that keeps the door for opening too wide is not located in the same place on the SW doors, I need to make a small braket to make it work
3 - On my ST the speakers are located in the door and the interior panel is built out to accomodate the size, on the panels I have I need to get a spacer ring so the speakers do not hit the window when it is rolled down.

That is it so far, nothing major, pretty straight forward.

You probably have new-type doors - the check strap changed design after 1994. All you probably need to do is get the new check-strap assembly and bolt it right on.

QUICK TIP: adjust Defender doors
By Simon Ward-Hastelow
Published: 30th Mar 2007
Original article: http://www.difflock.com/magazine/Modifications/QUICK_TIP_adjust_Defender_doors.shtml

There’s nothing more satisfying than hearing a door shut properly with a positive thud, some vehicle manufacturers use it as a selling point. But after a while the doors on a Defender will begin to fight back. THe hinges wear, the latch moves and before long you find yourself standing back and slamming the door shut to get it to lock properly. A quick bit of fiddling with a screwdriver can put it right.

The latch itself is held in place with just two bolts which attach to a plate with captive nuts in the door pillar. The holes in the door pillar are larger than necessary to allow the latch to be adjusted a fair bit. This also means that the latch can move backwards into the vehicle which means you have to slam the door a little bit harder each time for the door to contact the latch.

All you need to do is loosen the bolts and pull it back towards the outside of the vehicle.

In the picture (left) you can see where the edge of the door has been rubbing on the latch, in this case a shim needs to be removed (see below)

You can further adjust the latch fore and aft with the use of spacer shims (see picture below-left with red pointer) to make sure the latch is truly centred on the locking mechanism in the door. Usually this is only necessary if you’ve had the doors off for some reason or fitted different doors.

BE AWARE! If you fully remove the bolts the captive-nut plate could drop down the hole inside the door pillar (see green pointer) and it is a fiddly job to get it back out again. You don’t need to fully remove the latch to fit the shims they have locating slots cut into them so just loosening the latch allows you to slide a shim into place without removing the bolts.

If you need to adjust the the entire door, to straighten up the shut-lines for instance, firstly close the door then slightly loosen the bolts holding the exterior hinges on the door pillar (not the door itself) and raise or lower the door using the handle until the desired location is found then re-tighten the hinge bolts.

NOTE: if the bolts are rusty this is a lot easier said than done, spray them generously with penetrating fluid beforehand or consider replacing them altogether with stainless bolts.

D90 Overheating

June 14th, 2007

I’m surprised nobody has suggested the lowly $25 “Engine Coolant Thermistor”. I’ve had two episodes of “slight” overheating in two different vehicles that were remedied by replacing the ECT. From my experience, this sensor does not catastrophically fail, but each time it has failed, it followed the same progression. Overheating, random stalling, and finally Code 14(Coolant Thermistor). The overheating lasted for months as I replaced the entire cooling system to no avail. Then began the random stalling. That lasted a couple weeks before it pulled a Code 14. Replaced the ECT and all symptoms disappeared. Happened once again in another truck only progressively faster. Again replaced the ECT, this time before pulling a 14 and systematically replacing the entire cooling system, and once again all symptoms disappeared. I’d start with the ECT…

D90 ST Roll Cage Differences

May 30th, 2007

The ‘94 has a different angle bar off the back of the first roll bar. The bar has a bracket bolted on the bottom which is then attached to the capping. The ‘95 and ‘97 is molded rubber at the area that attaches to the capping. This is the only difference on canvas products on the Defender 90.

D90 CATS

May 22nd, 2007

I used Magnaflow Universal Cats #94004

They are pretty tight on the passenger side but do clear the frame. They are a metal screen type cat so nothing to break and rattle around.

I paid $54 plus shipping for them here.

Hope this helps. I have been very happy with them. The shop charged me $150 to install both, YMMV.

Air Breather Manifold Instructions

May 14th, 2007

Air Breather Instructions

There are 4 openings that are 1/4 inch. And 2 openings at 3/8 inch. The 4 1/4 openings will be for the 3 breather hoses for the front differential, transmission and transfer case. They are located near the back of the plenum (and in front of the air filter canister on a defender) The hoses that are the breather hoses have a ‘”U” bend in them and are not connected to anything.

Though the hoses may not all be the same length, Make a straight and bur free cut before the “U” part off the tube and then push them into the 3 1/4 inch push lock fitting on the junction block.

Mount the junction block in a spot on the fire wall with some stainless steel sheet metal screws. (Put silicone on the screws before final tightening, as this will prevent the fire wall sheet metal from rusting.) Or the breather junction can just be wire tied to something.

On the rear, the breather tube is wire tied on the “A” type trailing arm. The hose is tucked into the box frame and that is where the end of the hose with the “U” is. The best way is to trace the tubing from the banjo fitting on the axle tube up to the frame.

After cutting off the “U” part on the rear breather hose and cleaning, take the 3/8 hose and slide over the rear breather tube hose about +6 inches or so. To be sure it will stay put, put some super glue around the small hose before you slide the 3/8 hose on over it. Route and wire tie the 3/8 hose from the rear axle vent tube to the engine compartment and avoid being near the exhaust system, and insert it into the 3/8 side of the junction. Then cut a short piece of 3/8 hose and insert it into the opposite end of the junction. Cut a small hole into the rubber drain valve cock on the bottom of the air filter canister that will fit the 3/8 hose, this is where to insert the other end of the hose. Put some silicone around the rubber drain valve to seal. Plug one of the ports with the supplied plug.

To remove the tubing from the junction, push down on the small diameter gold push lock ring while pulling on the hose. The harder you push on the gold color ring the easier the tubing will release. Also if while pushing down on the ring and push down on the tubing then pull out, this helps also.
