Splined axle bearing question

[Rusty-Gunn]

We got the chains and T20 back in the Max. Getting the transmission back in the proper spot is frustrating. Getting the bolt holes lined up with the frame holes is ugly stuff. Always off a tiny bit.
I discovered when I use a two-foot length 2x6 shoved behind the T20 (and in front of the rear frame) I can use it as leverage to push the trans forward where the holes are. Easy enough now.

It's always the little tricks that make the difference in how the job goes.

Axle bearings... A bit confusing but not very diffecult.

Several weeks ago my wife amd I changed out the outer bearings, flanges, and sprocket sets to both rear axles. This was not too much of a problem, the work involved was easy, but took us all day per axle. A few days added in there to remove the engine and trans first.
After a week off for eye surgury we installed the trans and engine, then gave the machine a test ride. We heard some ugly intermittant noise from under the floor boards, which at first confused us. What was it? We looked but saw nothing. I tightened a few chains, thinking they were slapping the bottom. Nope, not the problem.
We put the M-IV on a few wheel ramps and didcovered the right front bearings were the problem. The middle axle outers also had too much play.
So, last night I read about the front axle from the manual. This confused me some. Most of it made sense though.
Tbone gave me advise on this (thank you). This morning we tore the front axle out, and replaced the outer bearings and flanges. It went together easy. I'm a hands-on kind if guy. The manual did eventually help, once I got to doing the actual work.
We took the middle axle out, which was the first axle out of four to cause problems. Rusted ugly. It took some "slide hammer" effort with the axle. Grunt and groan. Its out, waiting for tomorrow to be cleaned up and put back together. Anti-seize is your friend.
I want to thank the many members here who have helped me keep our M-IV in top shape. You guys rock!

Glad your making progress. it gets a little easier as you go.

[Rusty-Gunn]

Yes, it does get easier. And easier to understand to more its done.
Never having owned a Max before, and reading the service manual, does get a bir confusing at times.
What did it say? I'm supposed to do what? It goes where? Whats it mean?
Well, once we got into doing the actual work, and keeping those questions in mind, we begin to understand what the manual said.
Asking a few questions here helps a lot. Everyone is very helpful. It is indeed appreciated.
Using the search button and reading also helps a lot.

One thing we noticed when doing the "slide hammer" trick to get the sprocket off and axle out is the sprocket teeth scratch the bottom of the tub. Lesson .. put a piece of plywood as a tub protector.

Regarding sprocket tubes, how do you squirt grease into the zerks on the middle axle of a M-IV? The chains are very close. My grease gun tip won't fit between the chains. Am I supposed to remove the chains each time I grease them?

Its a simular issue for the front sprocket-brake set.
Whats your trick? Thanks.

I use a 24" flexible whip on my pneumatic grease gun and I can just wiggle it in there from the back side. The rear left is the hardest one to reach.

[Rusty-Gunn]

Thanks, Zuk. (I seen a few of you mud thumping vids)
We can get to the back zerks, but my grease gun nozzle won't fit between the chains on the middle axles. I'd rather not take off these chains just to grease the sprocket tubes if I don't have to.
Same for the front axles, the zerk is hiding in there lurking about, taunting me.

The inner bearings came in. These are labeled SA 206-17. These have an eccentric lock collar. The ones on my Max have two set screws.

I am not sure if these will fit the turned down portion, lengthwise. Do I remove them two washers? I assume they are spacers.

Anyone know if the would fit? (I'd rather not have to remove an axle to check).

[Mike]

The ID (17 = 1-1/16") and OD (206 = 62mm) are correct but I think instead of the SA, you needed a UC? Don't take my word for it though. What two washers are you talking about?

[Rusty-Gunn]

There are two washers that are on each end just before the inner bearing goes on. I thunk they help with sprocket alignment.(?)
I think Tbone9 said UC as well.
Looks like I will be sending these back for the UC versions. Thanks Mike.

[ARGOJIM]

The uc is what you'll need, as far as the grease a needle should work if there is enough room. A needle goes directly into the check ball instead of over the fitting.

[Rusty-Gunn]

Thank you ArgoJim. I will send the bearings back to exchange them for the UC versions.
I'll have to vheck into the grease neefle. I've never seen one before.

We got the Max back on the road. The test drive was good. We are very pleased. We are now ready for the summer.
Thanks to everyone who gave advice, we learned quite a bit.
