400 chief bearing

[rturner]

On my attex chief are the inner and outer axle bearings the same? one has a collar that comes off and the inner one does not. any part no. would be great Thanks!!

[Lantz]

Not sure if they are the same bearing, the one that the collar comes off is just a locking collar probably goes on the outside, and the one with out goes on the inside. Call the people at Buffalo bearings (1800-669-8019) they will be able to get you new bearings and/or flanges if you need them.

The inner and outer bearings are the same 52mm OD and 1" ID. The inners and outers both can have the eccentric locking collars on them, but the difference is the outers will have a "R3" at the end of them, meaning "triple lip seal". The guys at Buffalo Bearing will know what you need, tell them you have a 6 wheeler and the bearings fit in the two piece stamped steel flange. Let them know the dimensions I gave you and tell them the "R3" are for the outers.......the inners can be single or double lip seals.

Thanks JP, so does that mean since the outer bearing has a grease zert it just help's keep water out? Thanks!

[jpswift1]

Glad to help. It means the R3 bearings have 3 lip seals to keep the mud and water out. The outer bearing flanges are what has the grease zerk in them so you can pump grease into the bearings.......there's a very little hole in the outer bearing race that you line up with the grease zerk so the grease flows into the bearing.

Same bearing and info below applies to you. Just call buffalo bearing. You may want to just to the whole set, inners and outers. They know what you need. Make sure you use antisieze during installation. If the PO did not, they may need cut off.

Drew is absolutely right. And your Attex isn't a 1973 since it has the poly body by the way, it's a 1976 or newer, but it still will use the same bearings. 52mm OD, 1" ID "R3" triple lip seal and it fits in a stamped steel 2 piece flange and uses an eccentric locking collar. There's all the info you need.

in the vin on the frame it say 73 i thought thats what the year was?

[hydromike]

The numbers are really all general. The frame was likely made in 1973, but it could've been put in a machine in 1974 (or 1975? later?) when the machine was originally built. It's also possible that somebody else put the older frame into the machine during a fix-up years back. There's really not much of a difference between a 1973 frame and later units.

Less'n it's a poorly stamped 78

gotcha thanks guys

so whats the best engine to run in these my 2 stoke is a real pain in the rear

[amphibious drew]

That's a touchy question and really depends on what you are going to do with it. Personally, I like the Briggs 18 in my Attex. It's nice and reliable, makes plenty of torque, and does great on the trails. The 2-strokes are great go fast and scare the heck out of the neighbor engines, but are pretty noisy and not as trail friendly.
