My car is 1/8 to 1/4" from being drive-able, so I hope someone here can help.
The problem is arising with a clutch change. The issue is when the pedal is depressed to disengage the clutch, the throwout bearing is extending just far enough past the end of the transmission's output shaft to cause the oil ring to catch (mechanic says it is literally just 1/8" to 1/4"). This causes the throwout bearing to momentarily hang up and then crash back when it finally releases.
By way of background info, I have a '65 inline 200 with the 8.5" "dogdish" flywheel and a T5 transmission. Everything was purchased through Modern Driveline years back, and I've never had this problem (and the clutch has been replaced before).
Here's the head-scratcher... I had the clutch replaced just a couple months ago with the same bearing, clutch plate, etc. The issue was the flywheel was at the end of its life. We tried turning it one more time and installed it. However, I was getting chattering (but the clutch was NOT hanging up like it is now).
So, I found another new/old dogdish flywheel that was in good shape and had the shop swap the new flywheel in- THIS is when the problem started. The pocket depth is a perfect 1", so that isn't the problem. The mechanic said he tried taking out the play in an effort to decrease the travel, but no go. By the time he adjusts it far enough so that the bearing doesn't catch on the end of the output shaft, the clutch will no longer disengage (in fact, if you push the pedal in too far you just get a nasty sound).
Any thoughts would be greatly appreciated. I called Modern Driveline, and they've never encountered this issue (and they correctly pointed out the parts they supplied with the clutch kit worked with the old flywheel- so there must be an "installation error"). The mechanic says this is one of the simplest installs he's done- but he cannot account for why the throwout bearing is traveling just far enough to hang on the end of the output shaft.
The mechanic and I thought perhaps a longer throwout bearing would work, and I see a simple solution in just having the adapter plate machined down 1/4" (but the mechanic says we'd need to make sure the output shaft won't then make contact with the flywheel). Really though, I'm just trying to figure out how we're having this issue when the only difference is the new flywheel.
If someone has an idea, please share it... I want to put her back on the road to enjoy this beautiful spring Dallas weather!
