My 3 ' long 3/4" drive breaker bar wouldn't begin to budge the 1 1/2" axle bolt. I don't have a high torque 1" drive air impact so I ended up using a torque multiplying heavy truck lug nut wrench which broke it loose easily. The chassis bolts on my 773 prevent the jacks from being positioned exactly 180 degrees across from each other against the hub flange. At first it wouldn't come loose after loading the bottle jacks and hitting the axle bolt with the sledge. The 2nd time I gave it a few whacks on the back side of the hub flange between the long gap in the jacks and it popped loose. I cleaned up the axle with some emery cloth. The other hub flange wouldn't come loose no matter how much force I put on the jacks or beat it with my sledge hammer. I finally put a large gear puller on it and torqued it as much as I could. Then I swung the sledge under the chassis below the engine and hit the back side of the hub flange with enough force to knock it loose.

I've just managed to get all four hubs off and seals out thanks to your video. Off to bobcat tomorrow to get 3 seals and 1 seal kit as I will need a seal saver for one only. Thank you nice easy to understand vodeo.

Sealant under the speedy sleeve. I've had more than one instance where the slightest gouge on a shaft caused a perpetual leak. Its hard to get a good look all the way around a shaft. I'll add sealant to the OD of the seal if I have ANY concerns. Lot's of guys operating like the bull in the china shop. Always a dinged up sealing surface somewhere.

Do you by chance have a part number for this kit with speedy sleeve for a 2015 bobcat s550?
@Data57 Жыл бұрын
Just did new seals and 100% that the repair sleeve is on backwards and no seam made to break off the flange. flange is meant to go against bearing. I mean this way worked, but definitely not the way on the bobcat instructions with kit. Would be worried about metal edge break the flange off and catching the seal at some point.
@tetradgroup Жыл бұрын
Yes you are correct, this is not how the sleeve is supposed to work but its also not designed for this type of shaft. Everyone I have seen has the outer flange with a seem and I have broken the flange piece off to the inside several times trying it the other way. Keeping the flange to the outside ensures the sleeve can be installed all the way on to the shaft without breaking.

Axle seal for sure, raise machine and see if you have any in and out movement of the axle. If you have any play then it's time for bearings.

The axle will preload the bearings when torqued down and any play in and out would suggest bearings are worn and should be replaced.
