I have a VW type 1 engine that spun the #1 bearing. On

Customer Question

I have a VW type 1 engine that spun the #1 bearing. On tearing down, I find the bearing pin was rolled and the bearing pin hole is slightly enlongated. Is there a fix for that pin hole?
JA: How many miles are on the car? Is it an automatic or a manual transmission?
Customer: Manual, 60k
JA: What is the model/year of your VW?
Customer: 72, but the engine was completely rebuild 60k miles ago
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I did the tear down to replace bearings and check the crank. Took the crank to a machine shop for polishing. I now notice the elongated bearing pin hole. I'm thinking I could hava a machine shop drill a new bearing pin hole somewhere else around the bearing track.
JA: Anything else you think the mechanic should know?
Customer: The crank was not damaged.

Hi there,

You are better off getting the crankcase half repaired to keep the pin in the factory location.

The bearing has spun from lack of lubrication.

The pin is really only to help assembly.

Once the crankcase halves are torqued the bearing crush retains the bearings in the bore.

Now you will be rebuilding the engine, I would ensure all the oil galleries are clear within the crankcase and the crankshaft.

Plus all the usual rebuilding necessities.

I hope this helps.
