Max II bearings and flanges

[Rabbit929]

Found out 2 of my zerks are broke off, 1 bearing pushes all the grease out the collar, 2 push all the grease out the outer flange.

Long story short, new bearings.

I have Non-splined axles, and it looks like a type of bushings on the inside.

What do I all need to replace the bearings, inner flanges, and bushings? If I got it apart I'd like to go all the way.
Most likely be ordering from buffalo bearings. R3 type. 3 bolt.

Tool wise, you'll need a basic socket set, allen wrenches, a wrench set, and a hammer and chisel. Oxytorch, grinder and a hydraulic press are optional for stuck sprockets, bearings and eccentrics. To ease the process of replacing bearings the next time around, a little anti-seize is a fantastic idea.

For new hardware, depending on the year of your machine, you'll probably want and need 6 new zerk-less flanges, 6 new zerk-ed flanges, and 6 new 1.25" ID 207 bearings. That will cover your outer bearing setup. For the inners, you'll want 6 new inner bushings or pillow block bearing depending on the year of your machine. Mine is a 2003 max 2, and it uses 6 pillow block bearings ( cant remember the footprint dimension off the top of my head), 1.25" ID, 206 bearings. Yours may be different depending on the year. Make sure to check your parts over to make sure you get the right stuff.

Thanks! Would it be possible/necessary to convert to inner bearings and eliminate the bushings?

Rabbit your machine probably does not have 207 bearings but 206 bearings. You may be able to install the cast iron inners if there is enough room but don't order 6 of them on my account, you would have to try one on each axle for frame fitment.

[Rabbit929]

What is the difference between 206 and 207? Are we going by axle shaft size?

[Mike]

206 is a 62mm bearing and 207 is a 72mm bearing. That is the outer ring size.

[Rabbit929]

So they are not interchangeable? Is one not better than the other? Because if I get te flanges and the bearing all the same size, they should fit right?

[ARGOJIM]

The hole in the frame is smaller

[Rabbit929]

alright ill have some 206's coming on monday from buffalo bearings. i wonder if there isnt a reason we dont put those big heavy bearings with the thick pillow block on these instead of these split flange units.

[tbone9]

The bolt pattern on the cast pillow block is too wide for the frame and they're not triple sealed. I wish there was room for an industrial type bearing and housing.

[Rabbit929]

Yeah I was just curious because those seem like the way to go. For this application (if they were triple sealed) would be bulletproof.

***UPDATE***

Just got my bearings and flanges from buffalo bearings, $17.50 a bearing.
For the price, they did a damn good job machining these things. I measured the bored and they all came to the same measurement within .0003 ten thousands.

Only issue, there is a small ball on the outside diameter of the bearing that I believe is for locking the outer race into the flange. My flanges don't have a place for this ball, is it just supposed to dent into the flange or do I have the wrong flanges?

Pull the pin

The small ball needs to be pulled out. I use a small fine tip cutter to grab the ball and pull it out. Sometimes it won't pull so I cut it down as close as I can get it and then grind it off with sandpaper. no worries.

Alright thank you. I wasn't sure.
