Factory Upgrade 512TR/M clutch housing build

for this I always use red loctite, but I think blue will do it also

check the axial play for the center gear. may be you have to use shims for right adjustment?

 

Thanx Jo, as said before .... we are never too old to learn, thanx for this thread !!

But explain to me please ... WHY do you make this bellhousing for your car ?

 

right, original there are no shuims inside, but I once measured the axial play and it was 3/10 mm, so I put 1 shim with 0,2 mm ( you have to take the bearing out of the housing ) that the play was only 0,1 mm

 

I would say between 0,05 and 0.15 mm. the WSM says nothing

 

Any progress Joe ?

 

Thanx for update !

What is this Jo ? Is this an oil line between Oil connection Pipe 153759 and .... ?

Wy was that an 1994 update ? What went wrong

mel,

where do you have this pictrue from?

this is a return line for the oil from the primary gearbox ( so from the clutch down to the gearbox ) . have not seen this before but will make only sense when you have the oilpresuure line connected to the primary gearbox cover somewhere at the top. this I have on my competition, but the return line in my eyes makes no real sense, because the oil can passes through the original holes inside the gearbox.
if there would be no fresh oil coming to the primary gearbox this return line makes absolutely no sense because all of the oil will drain down.

 

355 f1's use those holes and they're blocked off in a similar manner in non f1 cars, so could be ferrari had planned to put the f1 system in the m but it never happened. I know they put an f1 system in one of the sultan of Brunei's 512m based cars (FX)...

 

Anybody know were a oil leakage came from in this area?

On the pic the oil is bad to see but there is a lot!

this looks like the buttom plug?
there sometimes oil is draining between the housing and the cover, sometimes the plug is tightened too much so the thread has malfunction or even the cover at the thread is broken
unplug, clean and put the plug with a copper seal and rtv/silicone in again and wait 1 day before filling in oil

 

Thanks Romano!

 

I agree with you Romano; it is on a 94 512TR ... made the photo myself because it looked so stupid ... (#2 was near by, not really relevant)

Maybe we can find out if there are more 1994 512TR cars with this modification ??

may be inside there is a riser? so like newer gearboxes have it. that would make sense, because then the oil level is always the same. but when there is no riser ( hope this is the right name?? ) then it makes no sense

 

Hello Joseph,

I am posting the link below for all to see as there seems to be some critical problems with certain new 154511 Flanges that are in circulation in the parts world. (I should mention very early on that these are not Hill Engineering parts!)

154511 Flange Issues

As our CRB456/550 Clutch bearings run on these flanges we thought it very important to make sure that people are aware of the problems that are out there.

If you need to ask me any questions please feel free to ask.

Regards

Paul Hill
