    JD G swapping to 70 rods and bearings

    What does it state for bearing clearances. I looked at my book again and the g book states crank pin 3.374-3.375 with .002-.004 clearance for bearings. So with that im thinking standard bearings would be 3.377 on the tight side to allow clearance. Meaning I'll need .002 undersize for a crank pin...

    JD G swapping to 70 rods and bearings

    In process of rebuilding styled g. I'm swapping the rods for 70 rods insert style. Was curious if any one knows the I.D. of the standard rod bearings. I've measured my crank and its withing 3.372- 3.373 round both journals. I'm assuming the standard size will work. But before ordering...

    John deere G gasoline coversion piston selection

    I wont be able to machine that far and feel comfortable. There is only .28 thickness i measure on the bottom of the bore wall. I dont think taking .375 out of .56 screams dependability. I can get pistons made from extreme tractor parts for $1100 rings and pins included. Sharps and a few others...

    John deere G gasoline coversion piston selection

    Thanks all. I'll give Hinrichs a call. I've come across the extreme tractor parts before but wasn't sure if I needed more data before calling in to order pistons. The F736R pistons I have are still in great shape. Plus I picked up a pair of what I assume is MandW style .045 when I bought the...

    John deere G gasoline coversion piston selection

    I'm currently rebuilding my grandfathers styled G sn/44321. It was still in all fuel configuration and am considering gasoline conversion as there is a hole in intake/exhaust manifold. Will likely need bored .090 over as its allready at .045 and #2 has pitting. I'm concerned about piston...
