Someone probably can break the workshop code: 202 Workshop may have been at Montreal.

Having had a closer look at the dat plate, I do not think it says 202 but 203 or 205. Jesse, can you please confirm?

The shop number is 205. Interestingly, this engine seems to have some problems due to the rebuild process. The engine has almost no perceptible wear. It has an oil contamination problem though. Small scores, and embedded particles in most bushings. As of today, I have all accessories apart. The problem seems to be a large wad of sand or other abrasive that was left in the fuel pump extension. Also. the oil filter motor was never conected to an oil supply, and the manual knob was still lock-wired. In it's short service life, the engine also ate a small piece of metal. Probably a screw. The suction side of the impeller is all banged up. After that, you can follow the progress of the screw through the whole engine by the marks it made. It ended up in no. 8 cylinder, and chipped a couple of edges off the piston before it was finally spit out. I read an article once stating that most aircraft engine failures in military aircraft (WWII era) were caused by foreign materials, mostly rouge, left in the engine during manufacture. Jesse.

Hi Jesse,

Interesting thread, pics, and info you've detailed about the foreign objects. I have bits of a number of R975-EC2's to rebuild into one or possibly two motors for my General Grant project.

Looks like you've blasted your intake and pushrod tubes - did you have to do much to clean them up inside or were they all connected up still?

Great to see your Sexton making good progress.

Regards
