Bruce Nelson said: (quoted from post at 17:38:57 03/01/13) Filed is what I meant. This causes the rod bearing to have too much crush as the shims contact the bearings and not just the rod. This is why I want to know the original diameter. If I can hone the rod to the correct diameter with the original amount of shims installed, I will have the correct bearing crush. Then I can remove shims and keep the correct bearing crush. The bearings have not been altered.
Bearing crush? on a babbit bearing? Oem procedure is to install the rod on the crank with a full shim pack,It will most likely be loose, remove one shim from each side retighten the bolts and check for tightness/ drag. Continue removing shim sets one at a time until the rod is tight to move. Then install one pair of shims back in and tighten the bolts and install the cotters, thats it. Works best to do this with the rods pointing down instead of in the cylinders. I find usually once I get the first one the other three
will be very similar in the number of shims needed. The shims do indeed contact the shells of the bearing they are made that way to keep the shells in place and so they don't rotate in the rod.

They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
