If the bearing is removed I bet you will find some shaved metal from the case.I know you can get them started crooked. But to be seated and still crooked? Seems to me that you'd have to ruin the case to do that.

You can run 20:1 in these things and the bearing will still go, it's not a lack of lube killing them.
What makes a 372XT different from any other XT? The same bearings are used in both XT saws and non-XT saws. Wouldn't it stand to reason that all XT saws running 50:1 will have bearing problems due to lack of lube if that were the case?
But how do you get a press fit bearing into a bore crooked like that? Is it ruining the cases too? I guess with a strong enough press, anything is possible.You can run 20:1 in these things and the bearing will still go, it's not a lack of lube killing them.

With any press fit you are counting on the material deforming. In this case it is unlikely the race is deforming, probably the case. Still, why can't the bearing wedge in at an angle?But how do you get a press fit bearing into a bore crooked like that? Is it ruining the cases too?

Well at the factory its not some monkey installing the bearings, its a 5 axis cnc press that outdoes a lot of monkeys.With any press fit you are counting on the material deforming.

For the original OP, your buddy with the four failures, well a lot can be learned from that, and the truth is hidden within.
I'm quite familiar with the difference between a manufacturing environment and a repair shop since it's what I do. Still, things go wrong constantly - jigs wear, people set things up wrong, parts are defective, etc.Well at the factory its not some monkey installing the bearings, its a 5 axis cnc press that outdoes a lot of monkeys.

For the original OP, your buddy with the four failures, well a lot can be learned from that, and the truth is hidden within. On each failure was the saw replace with a new one? Let me guess......the answer would be no........correct? Vac and pressure test results? Oh yeah none. Degree of bearing failure? Cage separation, how many balls lost? Yet another blank.
Best part of it all is the bearings, well all of the lower end is the same as it has been for years.
I have a dozen non - XT 365's and 372's. None have ever had a premature bearing failure.
Well you can throw all the rocks you want but you would be and are wrong. Each time a saw failed it was replaced with a NEW unit. The dealer is one of if not the biggest mover of Husky saws in Michigan. They do know what they are doing. I don't think a vac test is needed with a bearing gone, can't build vac with a hole in the crankcase. Should not matter the saw is under warranty and it does not run, that would be huskys problem, the dealer is the best I have dealt with and they make sure you are up and running, so being this was a major issue they hand you a new saw. The #5 saw that was/is failing was given back to them, the dealer could not warranty because it still was running. [Perfectly understandable, it did not meet huskys warranty requirement] My buddy did not care, he just needs a reliable saw so they gave him a few hundred off of a 576. I don't know how many 372's were returned but he said there was a bunch waiting to go back. CJ
Funny how Stihl recommended 50:1 long before the EPA regulated chainsaws. But don't let facts get in your way.50:1 oil ratios are actually a EPA thing.
I run 32:1
No they are not, sorry EPA is a US thing, that's it that's all. Apart from an arms length agreement with Canada, the EPA means nothing worldwide.50:1 oil ratios are actually a EPA thing.
I run 32:1
