According the the parts book for the 220, there are three jack bolts, all for use with the simple bushing (no key). Looking at used parts for sale at Wengers confirms this. Four came to be with other tractors, later or bigger. Tap them all and use six jack bolts!

6000 series don't use wedges, the wheels have a circular bolt pattern for a hub.

6000 series don't have bar axles. Yes, always a good idea to buy the special tap and chase the threads first. Anti=seize the bolts as you install them, they will want to gall the threads.

yes, 7/8 would also cover the 4wd's, 7580, 8550, 4W220, 4W305. Easy to tell just by looking at the hub, if it's a triangle with three bolts, it's the smaller D19-7000 style. Remember some 7010, and possibly 7020's had a lower cost wedge with just 2 bolts on each half, but still the bigger HD style. Making your own out of grade 5 bolts would not work, anyone who has actually done this job knows, you need to spend the money and buy the right bolts and tap to avoid more difficulty.

I searched in the Knowledge Base forum but figured it would be useful to clarify/list the sizes of pusher bolts for what models they are used for. Is the following correct?
3/4"-10 bolts are for models D19, D21, 190, 200 and 7000 7/8"-12 bolts are for models 210, 220, 7010-7080, and 8010-8070. |

The coarser thread pitch is going to make it harder too if they're really stuck. It's the mechanical equivalent of pushing a heavy load up a steeper incline. But, we don't know how tough they're going to be to move.
I haven't seen it mentioned here, and maybe I was advised incorrectly years ago when I first got my 7045. But I was advised to heavily and sequentially tighten the bolts, then whack the end of the axle with a sledge a few times, tighten, whack, repeat. My right side which had probably been moved a few times may not have needed that. The left however took me two more days, I'm pretty sure they would never have come loose without that shock/ vibration.

Grade 5 quality for an axle wedge pusher bolt would be a bad idea. A 7060 requires FOUR pusher bolts if the wedges haven't been loosened in years. Three is useless. Sometimes if the wedges aren't terribly rusty, two will get the job done, but it's kind of rare.

I lost track of the mission here. Are you in need of a set of custom 7/8"-9 jack bolts? I would buy 7/8-9x10" long bolts (grade 5 about $20 each) and a 7/8-9 threading die. Need to turn down the ends (lathe work). I assume 10" is long enough? I own a lathe, so that is the way I would go. I make enough things out of common bolts. Always cheaper than purchasing metal stock from McMasters and such. Another way would be 7/8-9 all-thread rod and weld a hex nut on the end, plus the lathe work. However I don't know the "grade" of the all-thread rod. But the cheap way out. |

I'll have some 7/8" -12 pusher bolts for the two piece wedge available at Baraboo. Will be driving around in an orange golf cart with two white racing stripes and an A-C logo on front.

This must be why I've seen so many impact marks on older tractor hubs at work.

Clear as mud. If it works for you, good for you. Personally, I can remember that fraction easier than your code for it. I just use the Pi button on the calculator, or the Pi command/ constant in Excel, or programming language. Then ya know you're good.

How do you know how close my playground is? You don't. We must use leads and helix angles calculated to .0000x. So, the "9" above. So like I said, barely close enough.

All four. Tighten each in succession until POP it is loose. I kept one regular bolt in loose so the wheel would not fall away from the hub.

How many do you need to do a wheel. I understand how they work, just wondering. Do you do both wedges or one at a time.

yes, 355/113 just real easy to remember it a 113355.... it's the closest any pair of 3 digit integers can get to PI.

Memorize. . . . .I didn't know you spoke Canadian. Memorize, I thought mnemonic tricks were supposed to be easier to memorize than the thing itself?
