When is it time to replace front drive axle bearing??

[SAB1]

My 2 cents....If I was on the extended warranty I would stick with the Yamaha bearings until the warranty is up. That way if it falls a part they cant say you didnt have Yamaha parts.

In reality aren't they Arctic Cat bearings or what they sourced out? I think that seems to be the issue with them. I heard they were sourced from China and not the best quality.

Over this past winter I have seen a few people mention they have replaced all the cheap critical bearings with high quality German FAG bearings.

Make sure they are in fact German before you get them. Got a FAG bearing this year, since the bearing shop didn't have an NTN(Sorry, my favorite) in stock. Said FAG was the best cause it's "German built". The damn bearing had made in Korea stamped on it.

I've never had an issue with NTN and they will keep being my bearing of choice in everything.

Don't know who Cat/Yamaha is buying bearings from.
SKF, NTN Black Ice?

We found the 10 pack of econo ntn bearings from royal distributing for 35.00 lasted longer than cat bearings on idlers

The are PEER bearings, an SKF owned outfit. Last I heard they were still run independently, probably to fill in the voids for cheap bearings in SKF’s line.

I don't see the sense in spending dollars on lightweight this-or-that on these machines when way bigger gains are easy to come by with horsepower mods.

My choice to try the bdx shaft was not based on weight but on tolerances compared to oem. Basically same price so its worth a try. Havent recieved it yet

A lot of the Cat bearings are Peer and Yamaha typically uses NTN but I believe the clutch side jackshaft bearing that Yamaha specs is a Koyo.

Figured it out...

To funny I was going to post this same question today. I know on my buddies winder we took the whole silver comma shaped housing off and used an old press to get it out and get the new one in. I wasnt a fan because that silver housing took alot of pressure and slightly bent. Has to be a better way. If I try that method again im tempted to heat the bearing a bit to get it out and freeze the new one before it goes in. I saw a neat video on YouTube to get he top Chain case side out with heat and a slide hammer.

With the chain case opened up and all the snap rings off on the shaft - after seriously heating the housing on the jack shaft clutch side you should be able to drive it out by tapping the shaft on the chain case side.

I removed the shaft and bracket assembly, applied heat to the bracket while the shaft was in my press. It let go nicely once the aluminum expanded. I used the jackshaft to tap out the chaincase bearing, again applying heat, it came out nicely.

Now I'm having a heck of a time getting the seal out of the chaincase. Any tips for that?

You heating with a heat gun or torch?

Whats your plan to get the new one in? Freeze it?

I was finally able to remove the seal, applied heat and was able to pull it out. I used a large socket as a seal driver to get the new seal in.

The chaincase side jackshaft bearing went in real easy, applied heat and used the jackshaft and a rubber mallet to drive it in.

Now to get the jackshaft in the clutchside bearing. I have the shaft in the freezer now for a couple hours. Hopefully I can press it into the bearing easily.
