Hi Guys,

How much float should there be between the back end of the gearbox and the propshaft flange.

Does mine look ok is it too much or not enough

Any advice gratefully received

Cheers

Err, pics a bit big there mate. Are you running live axle or IRS/de-dion?

Sorry about pic size Im running a DeDion back end

How long is the nose on the prop? Standard great big thing? If so, then a little extra gap won't hurt, and should remove any chance of it locking up. Not that it should with a de-dion, but I'd prefer to be on the safe side. Might also make removing it easier in the future.

How many mm is it, mines about 20mm

Its the standard big long thing, i think from memory ive got about 15mm gap

As said above, a roughly 1" gap should be sufficient. This should allow the enigne and diff to wobble about a bit without 'bottoming' out on the gearbox.

I always allowed 25mm when I built props.

As long as the prop does not "bottom" in the box you will be OK.

However under load the engine and gearbox and the axle can move quite a bit.

Thanks for the help guys, luckily ive not fixed anything so can move it no problem

Cheers
