Does anyone happen know how the cooling fans were balanced from the factory?
I took mine apart to refinish (Cerakote!) and very stupidly did not make any index marks for the front "ring" and back fan. I noticed on reassembly that there is a weight crimped under the ring lip, presumably for balance. I'm wondering if these pieces were balanced independently (unlikely) or as a unit...

My local machine shop said no dice as far as fitting it on any of their machines (ID of the fan shroud bore is too small). |

My local machine shop said no dice as far as fitting it on any of their machines (ID of the fan shroud bore is too small). Don’t know what those last couple sentences mean. It’s a very good idea to balance everything in your motor that rotates. Flywheel, crankshaft, rods, pistons/rings/pins, etc. That means get that fan balanced. Have seen pictures of an exploded fan and it’s not something you’ll enjoy. Dynamic balance all of it and if your shop can’t or won’t do it, send to someone who can (DPR?). |
