TR2/3/3A Crankshaft thrust washers.

During my engine rebuild I had a crankshaft end float of .010" so I ordered +.005" thrust washers. I thought the new set of thrust washers would be a total of +.005" but each thrust washer is .005" thicker so now using the new set of thrust washers I have .000" end float. I installed an old set on one side of the center main and a new set on the other side of the center main and now my end float is about .004" which is what I want. Is it permissible to mix these thrust washers or do I have to try to shave .0025" off the new thrust washers? I realize that the crankshaft will be off center by .0025" and is this a problem? Thanks and have a good day!

Nope, mix-n-match is exactly how you do it. Off center by .0025 won't make any difference at all, tho it wouldn't hurt to check the timing chain sprocket alignment.
 
I would make sure to install the new thrust washers on the side that receives the thrust when the clutch is operated (rear side of main bearing cap).
Too bad Triumph didn't use 360 deg. thrust washers on the TR6&Spitfire, like was fitted on the TR2-4A.
The cost would have been minimal compared to fixing the damage that was caused by the half circle TWs wearing and falling out.
