Ok, I've finally cut the p-rods and am loading them in and adjusting the valves. Right now it's on TDC for #1. I notice that when I turn the flywheel, at some point in the rotation there is a little tightness for a few degrees, maybe a 1/4 turn or so. My jugs were opened to 96mm with new KB's and hastings rings. Could this be just the rings on one of the pistons when down low in the cylinder? I don't know how free a new motor is to turn. The crank turned smooth as silk before connecting the rods, p&c's etc.
My hands hurt from the teeth on the flywheel so any thoughts would be great. |

i also suspect too thick shim washer between crank and flywheel
the most common mistake is to just reuse the same shims you must check your end play between the case and the flywheel i cant tell you how many times someone has brought me a type one after an owner rebuild with the statement, "just rebuilt it ,ran well for about 5 minutes and seized up." pull the engine , pull the flywheel , insert proper thickness washers ,instant fix. (IMG:style_emoticons/default/smilie_pokal.gif) in any case do not install this engine until you find the problem type fours without the plugs installed should turn without a lot of effort and NO binding good luck jt posting as my kid again |
