[Fot] Dreaded Thrust Washers in the Oil Pan

[Glenn Franco]

Group
Thanks for all the advice on managing the thrust washer issue on this 
TR6 engine.
Following Geoff Byrne's advice, I fired up my trusty Atlas lathe and 
went to work.
I machined a counterbore in the scored cap to accept a new bronze full 
circle thrust washer also machined on the lathe.
The attachment to the cap will me made with brass countersunk machine 
screws.

Plan is to see if the rear thrust washers conform to the scored, but 
somewhat smooth, crank thrust surface.
The owner wants to drive it this summer.
Also monitor end play and pull the engine in the fall if it becomes 
excessive and grind the crank.
It's not all complete but making good progress.
Thanks again
Glenn
