Need some help here, how do you get the outside bearing/oil seal apart from the shaft. I was thinking of a 10lb sledge hamer and a 2x4 but I thought I'd ask an expert before I started. Smile

If you just needs seals, then just pack the bearings and place sureseals.

Thanks, I guess this will prevent oil from leaking onto the break pads. What lubricated the outlide bearing on the original design, after disasembly of the hydrolic pump,PTO and rear axel I see there are quit a few gaskets/seals missing from this tractor and trying to understand how this tractor ran without them.
Thanks again

Originally, the bearings were lubed with hydraulic fluid. If leaking oil on the brakes is the only issue, then sureseals are the answer.

Depends,,, if you want to fix correctly one time and be done with it replace the outer seal also,,, it you are a gambler cover up the mess with a sure seal.. a sure seal is nuttiin more than a deflector that helps keep the axle oil out of the bearing,,, nuttin sure about it,,, if and they always are the outter seal is bad it will leak grease on your shoes

if you are willing to go for the kill You are gonna have to cut the bearing out with a torch are make a special tool to press the hub off...

That's a good looking press fixture, I could use one of those. How many ton on the press? Has it got enough arse to press off the collar and bearing at the same time or do you cut the collar first? I probably wouldn't have to ask if I was a guru, but I ain't. Not even an expert, just a regular.

25 ton,,, it pushed the first one off I tried (luck of the draw),,, set up a few more and I did not want to force the issue soooo,,, I took a air chisel and used it to rotate the collar on the axle about 1/2" (rotate not try and knock off) then reinstalled the puller,,, it removed the next 5 that way no problem... all 6 wheel bearings were saved ,,,worth the effort doncha think...

I don't think any one could make a argument that the outter seal does not need to be replaced,,, the purpos of the puller (other than I hate to cut all that mess out) was to save the beaing and do the job corectly...

I am sure you can build one (better) now get at it...

Another guy from arkansas build one from my chicken scratch out of pipe and he said it worked great...

One day I was a newbe and the next day a guru,,, Shocked Some how I got shoved to the front of the line Cool Now if i could get rich the old fashion way,,, inherit

Don't see any way to improve on the design, the square tubing looks to be the way to go for a good strong weld on the top side. If the bottom flange can be double drilled to also fit the 600-800 axles that would be a right handy thing to have around. I'm adding it to my "list".

Let me know what you come up with for the 600 deal,,, also when I torched the center hole out for the first plate I got it a tad off center so had to make another,,, I then worked on the fudged upped plate and it make a nice SS installer are lets say a good starter by using the hub stud holes to help start the SS...

Hobo's gold mine (scrap pile) 2 1/4" x 1/8" X 22 1/2" square tube'n,,,, hub plate 1/2" and 3/8" plate for the top ( 3X11") are what it takes to fit yer press...

The 1/8 tube'n took more than i thought it would
