    Here’s how I removed the wheel from the #7. Two cultivator shovels across the spokes, a week of penetrating oil applications and a small torch. Make sure you protect the threaded hole on the end of the axle. The gear puller will bung up the threads if you don’t! Oil seal was difficult to pry out. Try not to scratch or gouge the axle where the rubber seals on it.

    To protect the threads in the center hole, I hand screw in a headless bolt, and put a large nut over the end of it for the gear puller to be pushing on to save the threads and end of the axle. Make sure to be gentle with the amount of heat on the wheel. Jay

    Thanks. That’s a great idea with the headless bolt. I wanted to pull the axle right out but the tapered pin and bolt are seized to the main gear assembly. Have you successfully gotten those out on a difficult unit before?

    On some I have been able to get them out and a couple I have not. On one, I had to cut through the axle and ratchet casing to get the whole thing out because the tapered bolt had been wrenched too much and was no longer straight. If the tapered bolt/pin is not wanting to come out, I would carefully cut or grind off the threads so you can put a good sized drift on the end of the pin to drive it out(you will have to get another from Macknair or a parts machine) I just try to make sure when I start that I assume nothing and take every precaution I can the FIRST time rather than wishing I had. All the steel in these wonderful mowers seems to be both massive and relatively soft, so considerable care is needed to not bend or misshape bolts or castings or whatever. The castings will often bend some ONCE. Careful heat is required to bring them back, if one is lucky. I continue to be amazed at the care and ingenuity that went into these old mowers that we are still the beneficiaries of. Jay
