Axle seals

[1gr8bldr]

Spent the last hour reading post about changing axle seals. Most post are 743's, etc. Mine is a S250. Should I expect the same basic setup or is mine different in some way?

Same basic procedure except you have 3 smaller bolts that hold the axle flange on instead of 1 large one.

The main difference on a 743 is the axles do not need to come out on your machine, just remove the hub to access the seal.

1gr8bldr:You might also want to invest in getting a service manual for your S250 as well

Not what I needed. My manual is a operators manual. I will look for a service manual. I downloaded one for my ATV last week for free off the net. 475 pages

downloaded my manual last night. 3in thick. Gonna be a lot of good info. Replaced the cylinder seals in my 4 in 1 today. Whoever worked on it before had been using a big wrench on it. Had it all burred up. I made me a tool. Never put a wrench on it again. One seal, the inner, I was not sure how it went back. The old was so far gone I could not tell. 50% chance of being right. The schematics did not show which way

SomethingI found interesting. My Bcat hasHutchenson tires and rims. They are slick as you can get, just before getting into the liners. Getting a new pair of shoes next week. But the point is that while pulling the wheels to change the axle seals, I noticed that these things were EXTREMELY HEAVY. I was told that they were heavy, but I could hardly lift them to line up the holes. So I went and got the bathroom scales and rolled one up. 314 lbs slick without thread. Dang, that is rubber counterweight

Glad you got it all fixed...

after filling up the hydraulic fluid, and fireing her up, the right tilt cylinder was pouring. No wonder it was 2.5 gallon low. I picked it up from he whom had borrowed it and he did not mention that. Anyway, the other side looked as if it had a very slow leak due to the dust sticking, so I just finished rebuilding both tilt cylinders. Now I noticed the pivot point of the bob tach to the arms had major play. 1/2 at least. Back to the manual

dang, those gold cone shaped pins must be gold

keep in mind ,bobtach pivot pins are conical, if they have been movining , boom arms will need reamed or youre pissing in the wind, to be clear, where pin goes into loader arm should be a good fit(SOLID) they should never rotate. 360 2inches deep. if they have spun. arms will be elonageted . and need recut to accept new pin. if not done, a waste of time and money..

Not sure if I am getting what your saying. Any place I can research this. My schematics show a welded in bushing. My local Bcat place said no one replaces it. ??? Could you explain with a little more detail?

What he's saying is that if the taper in the loader arm bushing is worn a new pin will never seat right. Which end of the pin is worn, the end that goes in the Bobtach or the tapered end that goes in the loader arm?

Have not as of yet taken it apart. I will let you know what I find

The end going in the arm,the cone side is not worn at all, but the bob tach end is worn. With new cone bushing installed, still a little play. Bobtach bushings need replacing. Getting the bushing out is where I'm gonna need some advice

I weld a bar to the bushing and use it like a slide hammer to shock it out. I have an old steel rod with a big weight that slides along it. works a treat, used it to remove my car axle hub too.

will the bushing come out either way or do they only go one way?
