Endfloat Did you know!

[Parisien]

Manufacturing defect/assembly...no ifs or buts...if known about, and only reckoned to have affected a small number of cars...Maserati still duty bound to fix etc...regardless of age.


I mentioned before I had a 993 version of the 911, when it was 6 years old a recall/repair notice was initiated in USA then extended to Europe to replace a poorly specified wiring loom which had cought fire in a few dozen cars, the part loom cost £600 odd 14 yrs ago and a day and half labour.....no charge.

Maserati...please step up to the plate!

Is it the bearing or the thrust washers that wear? Presumably the latter "2" or "3" in the diagram?

Forget Russian Roulette, this is much more exciting!!!

 

[Parisien]

What I would like to know...was it a training issue for those guys or just a days output or one D*******S who did this?

Item 3 is the upper part and 2 is the lower half Paco. The endfload bearings or washers are 2 half moon spacers designed to take up the slack or slop of the crank in the journals.

initial wear will cause slopping when you depress the clutch and a drop in oil pressure. If the fault is not rectified, the 2 half moon bearings then can spin round so both halves are locked together, then it starts chewing up the crank face and journals. At this stage it pretty much terminal

The modification I had was a phosphorus bronze custom made half moon bearings (right) that are pinned in place so they can't move or rotate. The PB washers are more durable and can take a lot more abuse over the standard ones (left)

Dirty oil can also be a cause of any engine wear also.

Due to the fact that i don't know the word 'endfloat', as long as google translate doesn't, is there another word for it?

What you are discussing is very interesting.

Nigelo is the guru on the subject, read this:

Really good article Nigelo, thanks for that and thanks Conaero for pointing it out. My engine has good oil pressure at around 5 bar and sounds OK, but I think at the next service, just before MC, I will get the dealer to check just in case. I take it the notches on the old bearings are more or less wear indicators?

If your oil is clean, and your pressure is good (plus you have an auto) I would not bother, really, I would not.

Oil pressure should be cold: 5 bar idle, 5 bar under load
hot: 2.5 bar idle, 5 bar under load

Some 3200's seem to have an oil pressure hard over on 5 all the time, again, I would not worry about this as you would not be alone...Italian electrics hey!

 

[hodroyd]

Mine is more or less on 5 bar all the time, apart from hot idle when it maybe drops to 4.5 bar. I suppose in hot weather this may drop a bit more. I will leave it then and see how I go on, unless the dealer points anything out of course. I have yet to have the car serviced and at close to a grand I am expecting wonderful results, I live to be impressed.

You have strong pressure, you don't have a problem. Endfloat always shows up on the Oil gauge first.

Keep the oil clean and you won't have a problem if its gone this far.

PHEW! thanks for those kind words.
