Triumph TR6 - Does this seem right ?

Had too little freeplay in clutch and slave was leaking, so I replaced slave and hose. Got a little better, but still not enough play. Took it to a mechanic, he said the thrust bearings were probably gone, there was fore and aft play in the crank and the engine would need to be torn down to see if the crank needed replacing.
I would have expected the mains to make fore and aft movement impossible to the extent he describes. Is this scenario possible or is he trying to take me on a $$ ride. Thanks all

D.L.--Your mechanic is with it. Do as Don sez, and check the archives (particularly the fingernail estimate of endfloat). Also, since your said your replaced the clutch MC/SC, you have enough skill to replace the thrusts washers yourself and save the labor expense. If you still have questions, post back and we'll be happy to oblige. Good luck!

Unless you find pieces of the thrust washers in your sump (oil pan) chances are the crank is OK. You will be able to see the thrust washer/crankshaft contact surface and/or measure the washers with a micrometer to determine wear.

To get my crankshaft float in the right ballpark, I went .005" oversize on the most worn thrust washer. My weak memory says the back one(?). Beware the incorrect pictures in some shop manuals! Otherwise, its an easy and satisfying job.
