Forgive me for jumping on the tail of this thread (please tell me if it’s not etiquette), but its subject matter matches very closely with what I am currently dealing with. Perhaps a familiar story, but engine & gearbox (T3) are out to replace engine seals, so thought I’d utilise Pete Roper’s guide to minimise the brick-in-a-bucket syndrome of the gearbox. Upon lifting shafts from box, torrington thrust bearing separated into 30 pieces (29 rollers - one missing completely - and the cage). That got me questioning the other bearings. Double row and other case bearings seem reasonable, but I’ve decided to change anyway. There does, however, seem to be a fair bit of play in some of the pinion bearings. 5th, on the cluster shaft, in particular - which I estimate rocks by about 2mm at the outer edge of the gear. I assume this is excessive? I assume also (subject to there being no major visible wear), that I wont need to change the inner sleeve these run on - just the needle bearings themselves?
Any input would be most welcome and, in case you’re listening, thanks to Pete and John for your guides - they’re fantastic and very much appreciated.
