Thrust Washer pair, special size to customer specification TR2-4A. We offer this service where the crank is damaged/worn such that standard thrust washers will not achieve the required clearance.

These Special Washers are made from phosphor bronze and will usually only be needed on one side of the crank (Clutch pressure side). Standard or regularly available oversize washers can be used on the none clutch pressure side. 

To find the correct thrust washer size, assemble the reground and oversize crank (i.e. on the thrust faces) into the engine block with standard thrust washers both sides. Measure the end float and record. Remove the crank and thrust washers and measure the thickness of the thrust washers used on the clutch pressure side (rear). Add this to the end float measured earlier less 0.004" desired clearance and you will then know the thickness of the special washers you need. Let us have this figure and we will do the rest.
