David_Leech Posted June 5, 2023 Share Posted June 5, 2023 I'm in the process of replacing the water pump bearings on my 28 standard six. The outer races are a precise fit, but they can be pushed in by hand. I'm fairly sure this is not correct. I have seen this on some heavy truck king pin set ups, and that is by design. The roller bearings are nice and tight on the shaft. I don't see any signs the original outer races were spinning though. I'm leaning towards using loctite bearing retaining compound to secure them in place. I should have kept the original ones to see how they fit. I'm pretty sure they just came out as well though (it's been a while). Has anyone been into one of these and had this issue? I'd hate for them to spin and ruin the casting 1 Link to comment Share on other sites More sharing options...
Kenendcindyc Posted June 5, 2023 Share Posted June 5, 2023 I’ve rebuilt a few and they were all a slip fit. There are shims between the casting and the four bolt cover to set endplay. I’ve converted mine to sealed ball bearings. Link to comment Share on other sites More sharing options...
