Kubota M5700 connecting rod advice

Haymaker101 · Feb 23, 2017

Hi, I have a newly acquired Kubota M5700 tractor. I bought it knowing that it needed engine work and mybody and I toreapart. Turns out that it needs a connecting rod bearing but there appears to be some damage to the crank shaft itself. I am having a hard time sourcing every manufactured crankshaft.

Does anyone have any advice besides Messicks or Allstate ag for where to source a crankshaft for this engine F2803? Also does anyone know what the clearances are for the connecting rod bearing?
I can get the connecting rod and bearing from Messicks

Thanks for any advice guys

Here is one source for new, well worth it in my opinion as it comes with jornels, bearings, and rod bearings.

Here is one used (rebuilt) but they don't say if it includes bearings, that worries me because if the ground too much off, you won't be able to get bearings to fit it.

For clearences you will need the WSM for the tractor of the motor, but AI bet the fist crank I listed is already set up.

Thanks for the advice. I'm going to hopefully have a local engine building shop turn the crankshaft and go from there. I'll let you know my results. Thanks again

Just a note: If the crank has over .4mm of damage you won't be able to get bearings for it.
