Question for those of you who have rebuilt their ZF's... if there is noticeable input shaft play, does it follow that the rest of the transmission needs rebuilt (bearings, synchro's etc.,) or if the rest of it seems tight should I just replace the front cone and roller bearing and the related seals?
To clear up some questions, I actually have 3 ZF's, 2 diesel, 1 gas, I don't know the mileage or history. One of the diesel ZF's has a tight input shaft but ruined quill tube, the other diesel ZF and the gas ZF have input shaft play. My goal is to case swap or type 4 mod the wide ratio gasser ZF to replace my T-19, and get a narrow range "spare" out of the deal.
Naturally my choices will be different depending on how much work is likely to be required of each. If I'm looking at a full rebuild I might just change the quill tube on the tight ZF and run it " for now", while I build the wide range one, otherwise I might case swap the two "loose" ZF's, put new input shaft bearings, and leave the quill tube project for later... thoughts? Suggestions?
