HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


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 …

Torque Tube Bearing Issue? Empty Torque Tube Bearing Issue?

Post  87944turbo Mon Apr 08, 2019 7:08 am

I recently finished my swap and started taking a couple of short drives just to check everything out.  I now have this sound that to me sounds like a bearing.  I took a short video of it at idle.  The sound on the video is not quite the same as in person, but similar.  

I don't hear it at idle at startup, but will after driving it.  When driving, I can manipulate it w/the throttle.  Apply throttle and make it louder, let off the gas and it will almost completely go away.  Decelleration has a different sound than acceleration, but still a noise that wasn't there before the swap.  

Is it possible that it is something else?  I have had this car for ~15 years and this sound is new.  Seems strange to me that the bearings would go at precisely the same time as the completion of the swap.  Could it be an alignment issue with the torque tube?

Just thought I would pass this information along in case it's helpful to someone else. I emailed back and forth with Constantine this morning and he suggested that the driveshaft may not be correctly spaced in the clutch assembly.

[You must be registered and logged in to see this link.]

I have only driven the car a few times and very carefully at that just shaking things down. Hopeful that the driveshaft can be properly seated if that is indeed the issue. Also wishing I had paid closer attention to the spacing, live and learn I guess. Fortunately I do have a spare torque tube if it comes to the worst and mine has to be replaced.

Ya, most need to be moved forward about a 1/4". Only way too check is without the pressure plate and disk installed.

Wow, well that's terrible. Wish I had known that. I saw in the manual where it shows taking a measurement at the rear of the torque tube. But to measure that correctly, I htink I would have to remove the transmission, which is better, but not a whole lot better...

Spence, really appreciate your comments.  As I am looking into this more, I see people discussing the verification of the nub fully entering the pilot bearing.  What I am not seeing though is what to do about it if you have to make an adjustment.  

Say for example, the nub on my driveshaft is setting too far outside the pilot bearing, what is the best way to go about making it fit further into the pilot bearing?  It seems that the driveshaft location is more or less fixed at the transaxle end by the coupler and also the trans mount (mine is solid).  Would you have to move the engine back?  Say at the engine mounts, or where the crossmember mounts to the body?  

I'll have to take a look for sure, but my engine mounts are solid as well and I'm not sure there is any fore/aft adjustability there.  Also IIRC the crossmember allows for some sideways movement due to the elongated holes, but I don't think it allows fore/aft movement?

You can tap the driveshaft forward, just be careful not to marr up the splines (use a block of wood and a hammer, or something similar) When I did mine I had the transmission off, maybe that's not completely necessary, in which case I wouldn't know the best way to do it.

Once you tapped it forward, did you have any issues lining up the bolts on the coupler? That's my concern, that Ill tap it forward and my coupler bolts won't line up anymore.

They're not going to line up anymore
You have to redrill the pinch bolt on the torque tube shaft.

Bolt the coupler to the transaxle and use the coupler as your guide. Just be careful not to damage the threads.

Spence, so just to be clear, the steps are:

1. Move driveshaft forward

2. Bolt the coupler to the transaxle

3. Use the non-threaded portion of the coupler on the engine side as a guide and drill the clearance necessary on the driveshaft (being careful not to drill too far and damage the threads on the threaded portion of the coupler).

Does that sound right? If so, is a special drill bit required? IIRC the driveshaft, or at least the ends I thought, were hardened steel. Seems like it would be a real bitch to drill through.

Thanks again for your help!!!

Ya, that's it. Just use a good quality bit and some oil.

It may have lined up, but was the insertion depth correct? You have to check without anything but the flywheel installed

i checked twice even i was suprised. No redrilling on the Couple or the TT shaft at the transmission at all.. the those thick part was inside the Pilot bearing . i will be removing the clutch disk due to a defect in the spline hub which is loose . TPC disk defect.
