LM 002 thread

Okay! My bad, there is no central a/c condenser on FI LM. It seemed that the fans were sitting on an A/C condenser rather than water radiator.

Transmission cooler:
what pumps the oil there? As far as I remember, ours didn't have it...

The DD LM radiator setup:

On any LM I have worked on, carb or FI the electric cooling fans take up the entire space between the radiator and grill. There is no space left for an A/C condenser.



The fans move so much air it drowns out the radio. I rewired them so they only come on at 100c or above. They almost never run that way.


Every cooled transmission I have ever worked on had an internal pump for pressurized oiling and used that to move oil to the cooler.

 

Did you make that radiator? Have never seen that design.

 

Our PS cooler is behind the left headlight and the trans and transfer coolers are together down below.

 

These photos are from a few months back. You can kind of see the fan setup sitting right behind the radiator. There are two Bosch relays in the center and the housing is wrinkle coated black.

The RHD radiator setup was done by Prodrive.
It's weird because they had used the normal LHD steering box, which sits on the left hand side of the left frame rail.
So now they had it on the left hand side of the right frame rail. So it was only possible with a weird radiator.

BTW, I was happy with a fixed fan setup. Although it eats some HP, overheating was never ever an issue, once I tuned the carbs.
Usually I had about 85c, summer traffic jams were landing me in 90c zone.

 

That ia a copy of the original. My car along with the chassis 234 was converted to RHD by Prodrive UK. The weird shape is necessary due to the RHD steering mechanism.

 

From the picture it looks like Your car only has twin puller fans. There is no pusher fans from the front of the radiator.

Mine has twin pusher fans on the front and a mechanical puller fan directly driven by the engine shaft. My first pusher fans started at 85 deg Celsius and the second one at 90 degree Celsius.

 

Correct. If it doesn't hold up I may try something else but worse case scenario I'll just put the original fan back on. I like the look of the radiator in the front but pusher fans are probably a good idea.

 

I thought yours was 234.

 

My mistake. I meant 301. Mine is 234

 

A few old photos I found, This was Portman's demonstrator at the time, at their service centre in London, GB.

So here are the news.
The part #27 dubbed as Spacer is a viscous coupling inside the transfer case.
However, I'm 99% sure that in most cases it's already dead there, i.e. locking too soon and hard. So that's why you shouldn't run 4x4 mode unless sure that the viscous coupling properly slips and locks. I haven't found a certain test procedure yet.
In 99% you should change the fluid in the viscous coupling before engagement on roads. So every LM002 should opt for a transfer case rebuilding these days, as 30 years passed, and all these years the silicon fluid spent inside a case full of hot transmission oil.
As I've heard people do break the transfer cases, and that might be the reason.

 

Does anyone have details/VIN of the Green LM002 at Amelia this year?

The paint reminded me of Malcom Forbes "money green" Countach (paint was also on several of his other cars).

 

Hey guys, I'm trying to replace my LM002 clutch, any Ideas.

My clutch recently got burned, the car cannot be put in gear, even though i give it throttle it wouldn't move.

What should I do, and where can I get a clutch?

 

Sounds strange!
You mean, you can't put it in gear with the clutch pedal fully pressed? If so, would it start in gear? At firtst, it sounds like clutch cylinder problem more than actual clutch.

You can get a clutch at your local Lamborghini dealer or eBay (some people have NOS clutches).

 

Recently I've bought few Countach 25th anniversary repair manuals and I can now be sure that my distributor was OK.
The factory timing for L507 4V engine goes from 13 deg. advance at idle to 33 deg. advance at "over 5000" RPM. Which was exactly what I had on the down-draught LM002 with L510 4V engine (basically, identical, with only intake being different).

Whether it's right or wrong, it's a matter of discussion. The car was significantly faster with the wrong timing I've set later on.

 

+1 Did the same thing. Although there are other alterations, JLA12100 pulls much stronger than its stable mate (black LM earlier in thread).

 

Found some crumby before and after pics.

Awesome !

 

Just out of curiosity what did you paint the frame with? Was is a custom blend conventional automotive paint?

 

We matched the original color and then had a blend made, correct. Its been a while, I have some stored away with its original interior etc.

 

Hard to find accurate reviews of the LM. Even Jay Leno's was littered with false info - not saying he's not a great guy.

It was pretty good except for the Kevlar tire comment. I don't understand why everyone needs to attach some fable to the tires. They are Nylon just like every other heavy duty tire. The difference is DuPont owns the name Nylon so they called it by its scientific name Polyamid.

The guy showing the car in Jay Lenos Garage didn't know squat about them.

 

I was wondering if you had found some industrial coating in the right color or if it was just paint. It looks good.
