bearing clearances on big hp builds

[hhrecovery]

what is everyone running for bearing clearance on high HP builds

 

[DISTURBED]

Minimum .001 for every 1" of journal

mine are .002 to .0025. Always been told to set up a big HP motor loose.

Edit, not that that's really that loose, but I dont think I would have been concerned with .003

Bottom end stuff, just make sure its within Cummins specs. Its the piston to wall clearance and ring end gap that'll make the difference on a daily driver truck.

I was told bearings set right at max spec or maybe 1 thou out. Piston to wall and end gap 1 thou out of spec.

I agree
