Tach gear

Peter,

I realize this is a difficult situation for you. It seems to me, you have two options: send it back to the vendor for a refund (if he'll take it back) or send it to someone qualified to rebuild it. Option #1 is the better choice as Option #2 could be a bitter pill to swallow. After all, these gearboxes aren't cheap to refurbish. Have a talk with Roland Jaeckel. He'll know someone who's qualified to rebuild a ZF and he probably knows the guy who sold it to you too. His insight in that regard might help. Lloyd Butfoy (RBT) could probably refer you to someone in Europe who's a qualified ZF technician, if you aren't comfortable asking Roland.

Hi Peter – I agree with everything that David said.

A quick way to check the quality of the rebuild is to look at the ring gear attachment and verify that all the bolts are safety wired.

UPDATE: I see on page two of this thread that at least the bolts on the ring gear have holes on them for safety wiring. That's a good sign....

But in my opinion, right now you don't have a working transaxle. You need to figure out that problem, rather than holding on to the one you have just because it is a ZF. At the top level, yours seems to have problems that should make you very worried about what other issues might be inside.

P. S. I also agree with David that you should call up Roland, or maybe reach out to some of the German members for some advice. Good luck

Update

I found an older zf mechanic guy

He will look at my zf in the next two weeks. He is in munich and worked for zf the last 30 years

Peter,

Be careful. You need to use someone who has specific knowledge and experience with our ZF 5 DS-25/2 transaxles. Transmission mechanics will all say they can work on it but can you afford to take a chance? Check your guy out with Roland and/or Lloyd Butfoy. If they've never heard of him, I'd suggest you keep looking. Ask your guy where he gets his parts from. If he says anything other than RBT in California or Roland, walk away. Keep in mind, the last guy who worked on your ZF must have said he's qualified to work on it too!

I'm sorry to be so negative but it's just too specialized and expensive a component to hand off to just anyone. Your guy might be OK but make sure before you entrust him with the job.

Hi David, thanks for your words. This older machanic has made a lot of DS25 and he is working right now for ZF. I will get a invoice and a previous offer wich states the damagend areas. It is direct from ZF. They also have all the special tools for the DS25. This will be send to my seller, so he can also send this later to his "ZF mechanic" .
I hope this all will work.
Thanks a lot for your words again!

you are great ! Thank you all for your help! :-)
Sorry that I am here in Austria, otherwise I would make a big detomaso- Friends party now !

Thanks !
