HOW TO DO AN ADVANCED SEARCH.

For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Good Day Everyone

I have an early carbed SBC going together for my 944. What is the part number for the pilot bearing I need for the crankshaft?

Thanks,
Ed

You'll need an adapter and the bearing itself....

Hey There

Does it make a difference that mine is not a LTI? It is just an early carbed motor setup. Eric mentioned that I could just get the bearing from a local parts store. But I do not have the part number.

Thanks,
Ed

Theyr're both the same... Bearings are 15X35X11mm (6202-2RS) or 15X35X14 (62202-2RS).
Use the 15X35X14 bearing if you need/want more insertion/support on the torque tube tip.

I could not find the bearing anywhere locally this weekend. Is there some other kind of partnumber it would be listed under? I would hate to have to order it online and pay more shipping that the darn thing is worth.

Did you look at an industrial supply store or automotive? I bet if you go to an industrial supply store they can order you in the bearing.

Ok, I went to the engine shop to see how the bearing fits. It is too big a diameter to fit down in where the std chevy pilot bushing goes. There is a larger opening above that. Is there some kind of adapter that this bearing fits into to go in the back of the crank? I dont know if the recent LT1 and LS1 cranks are the same back there...but does anyone know what I need to get this bearing to work?

Thanks,
Ed

For the SBC/LT1 swap the pilot adapter is 0.600" thick, The LS engine adapters are 1.00" thick according to the tech drawings. I have found an off the shelf roller bearing that does not require an adapter for the SBC/LT swap as it has the GM O.D. and 15mm I.D.
I'll check for the part# I have it somewhere.

Cool...thanks. So, the 944 shaft goes in as far as like a muncie 4spd shaft does into the back of the crank?

Appreciate the help,
Ed

For the C5 Bellhousings (5.8" depth) with 0.600" TT adapter plates the 944 tt shaft inserts into the 944 pilot adapter at the first crank pilot recess area....

I cut my pilot adapters (GM crank to 944 pilot bearing) to 0.53" thick for SBC/LT1 engines and 0.93" for all LS engines so there is no rear clutch disc hub interference with the pilot bearing as it wears over time. You should make sure whatever disc you use has the rear hub face FLAT with NO PROTRUSIONS.

The off the shelf GM pilot roller bearing for SBC/LT1 that needs no 944 bearing adapter is....

SBC Pilot Bearing Empty Early SBC crank

Post  mred2nice Tue Feb 12, 2019 9:56 pm

Hello everyone

After trying to move the splined shaft forward to engage the bearing in the back of the crankshaft, I think I need to revisit the bearing in the back of the crank. I though I saw something about a thicker bearing that would stick out of the back of the crank. How much does it stick out the back of the crank? How far does the tip need to go in the bearing?

Thanks,
Ed

Here's an example. The only way to check this is without the pressure plate and disk installed. This is on a LSX but the same would apply for your motor. I had to move my driveshaft forward about a 1/4"

Ok, gotcha. So I can move mine more then. Just didn't know how much was ok. The recess in the shaft for the clamp...you just about had to make a new one? Or did you just end up kind of extendedin the one that was there?

Thanks,
Ed
