LT77 Gearbox bearing issue
darrens - 17/5/10 at 05:41 PM

Hi,

Hope someone could shed a bit of light before I remove it.

If the car is in neutrel and the clutch is release there is a definite bearing whine, depress the clutch and it goes away.

Anyone throw a bit of knowledge into likely culprit or am i better just taking the box out and sending off to someone.

Cheers

My TVR does that but not a whine but a sort of rumble banging and a sound of gears trying to enter the cockpit. Its going for rebuild in 2 weeks LT77 too

just sounds like the release bearing needs changing

Unlikely to be the release bearing

Sounds like one of the needle rollers in the box main shaft these boxes are really sensitive to the correct lubrication -- correct level and oil grade ideally MTF94 at a pinch Dextron ATF or 10w/40 engine oil as a 3rd choice..

I agree, unlikely to be release bearing as it would wine with clutch depressed.

It also wines when driving.

Looks like it's coming out!!

Cheers for replies
