Me and my old man rebuilt my t34. It had quite a lot of shaft play and smoked a fair bit. Cost about £100 in bits 360 degree degree kit with new journal bearings & staggered rear seal various gaskets, new studs and nuts. had to buy some mini circlip pliers. Took us a whole day to make a good job of it.

Running for 12+ months now holding 21psi and all seems fine. -- (probably go bang next week now)

I'd say have a go if your pretty handy with the tools
