||In researching the problems I might face with the TR6 engine in my 2500M I repeatedly came across the TR6's notorious
thrust washers. Surely someone in the 35 years since the TR6 first came out had found ways to ease the trouble. It was
through this searching that I came across Scott Helms and his replacement thrust washers. Below is the letter that came
with the washers I ordered from him. His website (linked at the bottom) goes into much more detail on the washers.

Ordered: 2 Bronze Alloy Thrust Washers at .091" & .092"
Thank you for purchasing the bronze alloy thrust washers. This order has been filled per your special instructions.
Please read: Be sure to locate the lubrication grooves facing toward the spinning crankshaft surface for optimum lubrication and performance. That surface has been polished to benefit initial wear-in. This bronze alloy material was selected because of its superior wear characteristics and performance. It is an excellent replacement for the plated steel OEM style thrust washer that has caused problems over the years. Keep in mind that even though this solid bronze alloy thrust washer is a superior product, it will not last forever. Wherever there is friction, there is going to be wear. As with any Triumph six-cylinder engine, regular crankshaft end-float checks should be performed. If the end float dimension exceeds the maximum specification limits indicated in your workshop manual, it is time for a replacement. An important feature of this product is that when your thrust washer has worn to the point of requiring a replacement, the spinning crankshaft surface does not quickly grind away against bare steel as what happens with the original OEM design.
There are various ways to check crankshaft end-float, and below is an example. You must choose the method that works best for you.
Important note: To extend the life of your thrust washer and clutch release bearing (throw out bearing), be sure not to hold your foot on the clutch pedal longer than needed (waiting at stop light, for train, etc...)
Other methods of end-float measurement: A) Dial gage mounted on magnetic stand and tip placed against crankshaft end. B) Feeler gages at the journal while the TW's are in place and oil pan removed.
