--------------------------------------------------------------------------------

The stats: Rebuilt motor dropped into car with aluminum flywheel & new stage 3 clutch. 600 KM on the car now.

When starting up from stop in first gear and moving in reverse, there is a pulse, shudder or chatter on engagement. Also when in neutral with the clutch pedal pressed I can feel a pulse through the pedal.

It is RPM related. At 100KM/hr the vibration is not bad, rpm under 3000. At 140KM/hr the car feels like it is coming apart, 3400 rpm?

I do have a leak from the back of the tranny coming from the output shaft. Would that leak if there was too much oil in the tranny? Or have I lost a seal?

This shudder was in the car before I changed the engine but only at very high speeds. 180KM/hr+. I assumed the wheel was out of balance.

My thoughts:
Bad clutch/flywheel?
Propeller shaft of balance?
Wheel off balance?
Warped output shaft?
Toss match in gas tank, walk away?

Any help will he good, thanks,
Earl

To me it sounds like a throw out bearing or the forks on the pressure plate loosing their spring pressure or worn. Cheaped out and didn't replace the clutch when the motor was out? I'd do the same thing tho.

Ummm...no.

The clutch & flywheel are new. I have this posted on my local forum and have been informed that the clutch chatter is normal for this setup. I'm not convinced though.

As for the vibration at speed I will have to get the wheels balanced and see what becomes of that.

The shimmy at speed might also be tie rod ends. I have to replace my whole front end on this car. Dosen't shimmy, but for Preventative Maintenance. Clutch engagement should be smooth and shouldn't pulse when clutch is depressed. A shot in the dark here, was the bushing in the flywheel replaced?

Tie rod ends sounds reasonable. I'll look at them tomorrow.

flywheel bushing? I'll have to look at that.

hey guys i work for toyota and if the out put shaft is leaking gear oil, then remove the tranny and replace the bearings inside sounds like they are worn out.
Thats harsh! I am hoping that whilr the tranny was out for 7 months in my garage, the seal dried out. :ugh2:

I have ordered a new one and will have this in late next week if I can. I'll post if this resolves it or not. :bigthumb:
