JD 70 diesel rebuild (MainBearing question)

Unstyled G Guy · Mar 9, 2015

Hey yall,
Decided to rebuild my 70 diesel and got the crank out and ready to head too the machine shop. Center main definitely needs reground. Started shopping around for new bearings and the couple places I've checked want an arm and a leg for them! Does anyone have a good source for main bearings? Would need to be undersized as I'm going to have them cleaned up.

Also, has anyone on here ran an oil line to the center main and if so how??

Thanks in advance!!

Have the cam re-ground as well. The cam in our 70 looked good until the cam grinder started measuring lift, duration and timing.

Takes huge buckets of $ to properly rebuild it. Bearings are all gone that's why Manitowac Motor Machine makes them.
