  • Axle Hub Removal Issue
  • With the wheels off the 8N I disassembled further, removing the brake drums, shoes and springs. On the left side the bottom shoe was oil-soaked and I assumed a leaking seal.

    Referring to the PDF in "How Tos" I removed the circlips, loosened the axle nuts (had to use a cheater on the right side; left side probably was not tightened to 450 lb/ft.)

    Bought an 8-inch 3-jaw puller and after quite a bit of torque and some banging with a hammer the left hub came loose. From there I was able to strip down to the bearing.

    But the right side is more stubborn: I torqued until I couldn't turn the screw any more with an 18" breaker bar and socket. I banged on the hub to no effect. I left it under tension overnight and returned in the morning. I tried a large pry-bar, also tried pounding a wedge behind the hub. No movement.

    The "how to" mentioned heating with a torch; I tried that, along with wedge and lever. Nothing.

    By now I have fried whatever seal was in there, so the hub has to come off. But how?
    Any suggestions?

    Thanks for your replies.

  • One time I took a 6 foot iron T-post and bolted it to the hub. Heated hub and levered in and out with post a lever arm. It finally popped loose. I still had other back wheel on tractor so it was still somewhat stable. So be careful not to knock it off the jacks, or drop it down on some cribbing. Leverage is your friend.

  • The easiest way is to loosen the axle nut a turn or two and take the tractor out and work it.

    Pay attention. It will pop loose.

  • Thanks Dean for the suggestion.

    Here's the problem: The tractor is on jacks and I have no rear wheels.

    This all started with a failed inner tube and chloride damage to the wheels. I saved the center discs but am replacing rims, tubes and tires. Rims and tubes are acquired, tires (on order) and assembly yet to come.

  • In that case, I expect you will need heat and lots of it.

  • Takes a huge amount of heat when siezed like that. I have burned more torch gas on them than it would cost for the shop with a 100 ton press. Even with the press when it lets go it will shake the building!

  • Success! Cranked a few more turns on the puller and heated the bejeezus out of the hub: kept at it until the axle nut and washer were glowing and eventually it popped loose. This was not a job for your Bernz-O-Matic torch.

    BTW- Read and observe the caution in the "how to": loosen the axle nut but do not remove it from the axle. When the hub does let go it comes off with whatever force the puller has applied, i.e. lots.

    Thanks to all for their suggestions.

  • I thought I had plenty of heat on it: I wasn't using a small torch.
