Randall, thanks for your reply!
The three repair manuals I have do not mention the distance piece as a
means of adjusting the endfloat, and admittedly the TRF Parts Catalogue
makes no mention of the endfloat at all. Poor reference on my part. My
Bentley Manual reads on page 282: "Adjust by selective use of thrust
washers or if necessary remove metal from the steel backing face of the
thrust washer."
The inference I get from Kipping's remarks are that the endfloat is not
critical. This is the first TR6 transmission with which I have had this
problem, and I guess I'd like to know from others more experienced in
TR6 tranny rebuilding if the .004" out of spec. makes any real-world
difference.
Moss's price on the distance piece is $17.90, so to have one fabricated
the needed length form Herman van den Akker might be a little pricey
compared to some shim stock.
The transmission appears to have been serviced sometime in the past and
whoever did the rebuild went to the trouble of bending the front thrust
washer to (I assume) attain the correct endfloat. One of the layshaft
needle bearings had lost a roller and had begun to scar the laygear, as
well as eat into layshaft, so the car probably had a few miles on it
since the last work was done. The rear thrust washer showed almost no
wear and the front washer only showed wear where the high spot of the
bend occurred. This leads me to believe there is not much lateral force
exerted on the laygear in operation.
I'm going to email John Esposito about the problem and will hopefully
hear from him Monday.
I will post his response to the list. Looks like this rebuild won't be
finished this weekend as I had hoped.

Is that the sentence that says "Reduce excessive endfloat by selective
assembly of available thrust washers and distance pieces." ? I couldn't
find that in the TRF parts manual ... only in the factory workshop
manual.

Here are some comments I saved from John Kipping on another list. He
wrote this in regards to a GT6 trans, but I don't see any reason the
same comments wouldn't apply to a TR6 box :
