Mumbles.
It looks like I have not described the problem clearly. The looseness is between the small end of the rod and the piston pin. The roller bearings on the big end of the rod are ok but the small end sleeve bearing is loose.
Should I try to find some NOS rods or maybe I could replace the small end bushings on my present rods?
Thank you.
Steve,
There likely are some used rods available but they may also have wear.
Correction” I had not seen Mumbles answer.
Mumbles, I have some Naval bronze and a lathe. I wonder if once installed, the bearings could just be lathe bored or reamed with an adjustable reamer. Do you install the bearings into the rods? Just a press or by heating the rods /cooling the bearings?
