alternator 303.5 bolt hole

TomWei ยท 2021-06-04 08:35

the tension bracket broke on the alternator. when i pulled alt the bolt hole was 1.5 normal size. the bottom bracket holes are 2-2.5x size hole should be. backets are coming in from australia but can i shim the alt or do i need a new one? alt is 85 brackets were 400. guess i could keep as backup afw00807

    Not sure what you mean by shims but a lot of alternators come from the factory with steel bushes pushed into the alloy from new. They are slightly over sized with a split down the side to allow them to shrink slightly as they are pressed in. If you had access to a machine shop they look like they still have enough material left to bore out and fit a bush.

    parts came in yesterday to cat but bracket is backordered. guy was busy and people behind me so i just grabbed the parts they had. I'll find out tomorrow if its delayed or not available. can machine shop bore the hole for bushing? it looks like 10.9 grade.

    I don't see why a decent machine shop wouldn't be able to clean those holes up then turn you some bushings.
