Thread: Operation Ralph!

Hi Ian,

I believe the reason for jumping out of gear is worn synchros. The springs can help but are not the cause. It's more usual for it to jump out of third though.

Is general wear... When I worked for zenith engineering they used a die grinder on at least one gear to get around it

Thanks Tim, Dave. I was lead to believe it was a completely rebuilt unit when I bought it, looked good inside but you never know.

Yep, it looked very good, but we didn't get far into it when we played with it,....

Well i refitted the floor yesterday morning and went for a run down to clunes, for a family get together, its a lot better but still does pop out occasionally. Think i will just have to put up with it for a while, i reckon it would be better if i fit an over driveto take some of the backlash out with lower revs. Now to find one.

Unfortunately rebuilt could men just that. Taken apart an put back together.
It doesn't mean it's been rebuilt to original specifications. As for an overdrive , I would never pay good money for a secondhand one unless it's dismantled so I can inspect all the bits. .W.

Did you have a good look at the selector shaft where the detent balls sit. If they're rounded,and not a clean hole,that would cause it to jump out of gear.

Just having a look at this thread. Apologies if this has all been suggested earlier..... Yep, the usual things like detente balls, springs and synchros could be to blame Also possibly worn gears, spacers... all sorts of things!
