Hi,

In need of the technical know how of the members on this site.

While out driving the other day (1973 MGB UK spec car) all was fine until I had to reverse,
on selecting reverse when releasing the clutch the car stood still, there was a type of grinding noise (sounds to me like 2 surfaces slipping over each other) coming from around the clutch area.

sometimes on reversing sometimes the problem occurs sometimes not, forward no problems or clutch slip(so far).

I am thinking clutch or release bearing, but thinking if it is the clutch then there would be problems in both forward and reverse gears.

I would appreciate your expert input.

Zab

From the slightly vague description, I'd want to ask a couple of questions?

Did the car move in reverse, or just make the noise? It could be you didn't quite get it all the way into reverse.

And I would think that the clutch would work either way.

77 MGB - Four tone paint -Pertronix - hood props - cheap tires - new springs all around - mixture of poly and rubber bushings- fuzzy seatcovers - stereo out of old F150 pickup -runs flawlessly and drives nice.

78 MGB - Done right by a good PO, and I only bought it. Tell Jim how nice it is. But I did put in a Datsun 5 speed.

This car is now very nearly completely done. Sure to find something else, but not now.........

Eric-
From your description I'd venture that your reverse gear isn't properly engaging.

I bet your car has overdrive.

I bet the unidirectional clutch has failed...

thanks guys for the rapid response,

the gearbox (specifically reverse gear), clutch and overdrive will all be investigated, looks like the motor and gearbox will have to come out anyway.

will report back.

Remember there is a lockout switch to prevent the OD from engaging in reverse.
Check the switches on the tranny too.

Had a similarly problem, turned out to be a disintegrated carbon release bearing.

Peter,

I think you may be right, I've had a suspicion that the release bearing has been on its last legs for a while now.

Will look into it.

thanks

Eric
