ZF Inspection

[Brian Coombs]

Hi Guys,

I have just taken the cover plate of a Pantera (dash2) ZF gearbox I bought in an auction a few years ago and I was pleasantly surprised that the crown wheel and pinion look almost brand new. Am I right in thinking, if it has been lock wired, then it's been re built in the past?

Also I have to do the modifications to flip it and while it is apart is there anything specific I should check, apart from syncro ring wear, cracked/damaged gears and worn bearings etc?

Thanks,

Brian C

Are you flipping it to the GT40 position? If so, many other things need to be addressed.

Yes, Thanks Rick, I know all the changes needed, I was just wondering if there was anything specific to check while it is apart.

All the gears, synchros, and bearings. You only tear one apart once hopefully.

As you have discovered it's possible to remove the bottom plate (Pantera orientation) to access the Crown Wheel & Pinion and thus the safety wiring can be undertaken without ever touching the rest of the internals. The Pantera vendors sell a safety wire kit and it's a job most home mechanics can undertake, whereas a rebuild is not, so no I would not assume it has been rebuilt in the past just because it's safety wired.

Excellent post Julian. Very informative.
Thanks for posting that.

Thanks Bob, I will check the syncro gaps when it is apart, I come from a motorsport background, so are used to dog rings, but have done very little with syncro rings, so this is a bit of a voyage of discovery!

Do not forget that the big nut for pinion have left treads if you need to take this apart.
