After a year and a half I am finally close to making smoke. Too many things to do when I get home from work. My goal in the next two weeks is to get the base built and fire it up for a minute or two. Once the Roid smokes, I will split my tractor and fix the multi-power and the PTO brake on my Massey Ferguson 175 diesel.
I am timing my 18/1. It appears its the same as any other... 20 degrees, which works out to 4.090 inches BTC. After timing it, the fuel injector tappet holds the injector pump off the cover about 1/8th of an inch when I remove the pump mounting bolts. I thought I heard somewhere there should be clearance between the tappet and the pump? Does roughly 1/8th of an inch sound right? I didn't measure it... it could be more or less. Also, the reason I ask is I took the pump apart to check it out. I can't imagine I got the pump back together wrong because I put it back together 30 minutes after I took it apart, but I am getting older.
Also, I made my TDC mark using a dial indicator, but my 20 degree mark may be questionable. The flywheel circumference is 73 and 5/8th inches. So 73.625 / 18= 4.09 inches. I'm just trying to think of things I could have done wrong if there is supposed to be clearance between the tappet and the pump. BTW... the 1/8th inch is while the injector lobe is 180 degrees away from the injector pump.
