Worked on the HS40 today and I got a lot done....well a lot for a old guy ! :laugh: Cleaned the block last week with the final trip to the car wash, yep nothing but hot soapy water. Then blowed it all off the air pressure.
3/16'' key way cut for the clutch on the pto shaft. I had it cut over the top of the original 1/2 moon key slot that was in the crank to begin with.
Crankshaft cleaned and ready to install.
New tec rings.
Piston installed and rod torqued to 105 inch pounds, with plenty of oil on the rod bolt threads. I kept up with the Int lifter and exh lifter so no valve adjustment was necessary. Valves cleaned up pretty good ...but I did lap them in with lapping compound...also installed new stock replacement Tec springs.
Valve cover got taken apart and cleaned in side and out.
