Just wanted to ask some advice before I move forward. The rear rims have been rotten on my CA for years, but I kept using it until they finally collapsed a couple weeks ago. I have new power adjust rims for it but need to get these apart. I got everything lose, except the locks. I currently have them soaked in Shop Stufff (a canola based penetrating lubricant), and Krown penetrating oil. I don't have the tool for them and as you can see, one of the square nubs was already broke off when I got the tractor. Sorry, I don't know all the correct terminology for each of these parts, so bear with me. So what would be my next move? Should I apply heat? And if so, where?

I recently put new rims on mine. At least that bad. I just used penetrant soak for a few days then careful hammering. Didn't damage anything. Even got the locks apart. I put new 12 inch rims and 13.6 tires. Looks mean. I can't wait till it actually runs :) Brother just took block and crank to machine shop.

| put a block of wood on the center and hit it with sledge hammer you knock the center out of the rim and the locks will come off. When i had frozen locks I literally put them in my wood stove for a couple hours then took them out let them cool off a minute or two then worked them free while in a vise. I know it all sounds quite crude but i did 3 sets that way |

Lay the wheel on the ground, on a clean sheet of plywoor, or tarp (easy to find the parts, thataway, especially the rail followers). Then give the center a couple taps between the clamps, all should fall away fairly easily. If not put some more penetrant in th clamp, and hit it again, later. As for the clamps, themselves, watch this video: https://youtu.be/l2qXT3GGc5w" rel="nofollow - https://youtu.be/l2qXT3GGc5w On edit, I see one of the square heads has already been snapped off, Not real sure, but you may be able to weld a nut on it. Square ones are prone to snapping, more so than the hex ones. I always try to get them moving in and out, before trying to twist them...

Glad I asked here now. Thanks all. So I should be able to hammer the center out? I tried just easy, and it didn't. I thought maybe I HAD to get the locks undone. You can see where I got the wedges moving, by the break in the paint, but that's as far as I got. So is everything pretty tough? Can I just put a wood block on the center and pound on it? I did read that trick on this forum about putting them in the woodstove overnight. That one that is broke off, can they still be bought new?

[/QUOTE]
Move them in and out before twisting? So do I just tap on the square heads with a hammer to loosen them up?

You may want to put a socket over them, hammer on the socket. Doesn't matter what size or square or hex, as long as it protects the head from mushrooming. Hammer from front and back, alternating, add penetrating oil as needed. sometimes it takes an hour per clamp, sometimes more, to get them moving. Once you get the front-back movement, then try twisting. When you get the front-back movement, then you can pull the snap ring off the back, allowing more penetrant in... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

I used a flat end punch or a bolt a little smaller in diameter so as not to damage the outer edge. I didn't have to use any heat. I did have to hit pretty hard. This was after 30 years of sitting in the weather.

Thanks a lot everyone! I'm just letting everything soak for a day or two. I appreciate that offer Jay and Leon. I definitely need one to replace that one with the stud broke off. Not sure if I will need any more or if I will be able to save them all. But I'm in Soviet Canukistan (Canada) so I don't know much about shipping stuff, but I will definitely have to pay you for that because it probably won't be cheap.

So I sprayed everything with Shop Stufff, a penetrating fluid made from canola and they have been sitting for the last week while I was off driving my other tractor in a couple parades. So I had some time today so I laid them down, gave a whack with a big hammer like you all suggested and everything fell right out! Tomorrow I'll just the wedges in the vise and see if I can get them apart.   |

Once you have the eccentrics apart, cleaned and in working order, unlock the eccentric. If possible have a helper hold the wheel center and start loosely assembling the clamps in place in the rails. Once all 4 are loosely bolted In place, start tightening them evenly all the way around. They will become tighter on the rails. It will require the power of the tractor to slide them on the rails at this point. Once you have them where you want them, turn the eccentric to the right-until it hits the stop. Once all 4 are locked down the wheel will be locked in place. Make sure you put a locking collar on each side of a clamp to make sure it doesn’t slip. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

I saw somewhere, a guy use a round bucket of the right height, to hold the center up off the floor, then assemble the bits and pieces. I KNOW that's how I did one for my D-14, 20 decades ago.... good news is a CA rim/tire is lighter than a D-14 ! ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

I, too, use the 5 gallon pail trick, but I also lay the 'tire and rim' assembly on 3 pieces of 8 X 8 Post. That way you can reach under the tire to install the attaching bolts for the eccentric body. You can easily slide the eccentric over the rail and down in to position on the wheel. G |

Looks exactly like mine when I took them apart. They looked like new when I got finished with them (other than the pitting beneath the locks).

I did have a little difficulty getting them back together. Was a very tight fit. One was easier than the other so I thought the tolerances on the rim was a little off on one.

So again, I haven't had time to try and unseize all my rim lock parts. I will eventually, but want my tractor mobile. I was looking at all the new rim locks available and saw these. They are shown as out of stock here, but have found them at other suppliers. My question now is.....do these not need circlips and the rectangular blocks (Eccentric Pin Block) that sit on the pins like my original ones do? Or do I need to still use those?

| That is the lock not the eccentric. It goes through the hole in the rail to prevent spinning wheel on rails. |

I'm keeping the old rims. Not in good shape, but repairable with some effort. I thought I might use them for duals in the future...or not.

I put my wheel centers back on my D17 rims today. Had some help to make it easier. Bolted the first clamp on the wheel center. Had the wheel standing up. Placed the block(parts manual calls it a block) in the clamp(my parts manual calls it the body) and laid it on the rail at the bottom. Slid the next clamp on the rail opposite of the first one and installed the bolts loosely on the wheel center. Placed the other clamps on and and again loosely tightened the bolts. Slid the wheel center up against the stop and tightened all bolts. Once in place I tightened down all eccentrics(manual calls it pin). ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

I finally got everything apart! Went better than expected. Three of my eccentric pins are pretty good shape, but three are pretty scabby and wore. And one has the head broke off. But at least I'm relieved I got everything apart.

| Put the center back on the tractor . One eccentric straight up put tractor in gear so it wont move roll the rim over and put one rail on the eccentric jack tractor up till rim hangs. Install the rest loosely. Tighten all to center. Tighten bottom eccentric turn wheel 90 deg and tighten turn 180 and tighten bottom eccentric. They should all be tight now. |

Can't tell 100% but some of mine looked almost that bad but I was able to chip and grind them back into shape with some effort and they were smooth as butter and locked up tight. I would recommend new though. I really wanted to keep it maximally original so was a little obsessive about making it work :)

As long as the cams hold the clamps tight, that's all you need. Also, smear some anti seize lube on the cams, to keep them mobile. I'd start looking for some cams that match up with the square heads, or get all of them to hex heads, that way you only have to have 1 wrench, to adjust... ------------- Source: Babylon Bee.

Our CA also only has 3 esentrics on each side. Honestly didn’t pay attention to that since dad spun them in 25 years ago when he mounted a L306 belly mower on it. When I walked by it today it reminded me to look.

Well found an easy way to hold everything up while I pieced it all back together. Went together with no issues! Except one, which was my own stupidity because this is the first time I have worked on these. I left the retainer circlips off, thinking I'd put them on last, then realized there was no way to get at them with the wedges bolted on. So off they came again one at a time, LOL One question though. Maybe it's just due to the wedge blocks and pins being wore different, but when I tightened the eccentric pins they are all not pointed at the same point of rotation. Does that matter? And I couldn't find proper paint match anywhere in my town, so gave up and just put it back together. I gotta paint the whole tractor down the road anyway.
