: : : Have finally gotten my WC put back together. Started her up and there is a squeal from the motor someplace that is out of place. Could I possibly have a connecting rod bearing too tight? I checked two of them with plastiguage and have them at .004". Used the same shims on the others. : : : My problem is I am starting to get old at 77, and I have a problem laying under the darned thing looking up. I looks like a helicopter for a while!!! And I hate to go through all that again. : : : Any suggestions? : : : Thanks : : : Don Foster
: : : Paonia, CO
: : don, i have two possibilities. one is that the other
: : three brgs. shouldnt be shimmed by measuring only one
: : because the oil clear could vary greatly from one : : to the other. the next is, if you had your pistons out,
: : did you remember to offset the wrist pin to compenstate
: : for the offset throw in this engine. you know many
: : allis engines have this offset pin arrangement and : : it can make a noise and will ruin the cylinder because
: : the pin, when the engine is running, will be rubbing against : : the sleeve. i can relate to working on the shims upside
: : down, i hate it. but in about fortyfive minutes to an hour you can
: : have the engine out of the frame, and i an engine stand so that : : you can do this all from a stool, and believe me, : : thats the way to do it. regards, grapeape
well don, i couldnt speculate on the gear wear, but maybe it is your pilot brg.. have you oiled the wick lately?regards, randy : Thanks Grapeape. No, it isn't a wrist pin. The rod bearings are not too tight. It may be the pilot bearing in the fly wheel as the wick may be not functioning as it should. BUT I had noticed that the gear on the front of the crank shaft was worn off on the rear edge of the teeth. What could cause that and might that still be the problem? I have to take the pan off and correct a leak in the front main pan seal so I'll take another look there.
