Duals on a 1066

blkeele · Jan 8, 2010

I've got a 1973 International 1066 that I'm wanting to put dual wheels on. The local Case dealership told me there are two different axle lengths they made with this model. One is 118 inches and the other at 100. He said that the ones with 100 inch axles would be to short to put duals on. I don't know which one I have yet. Have any of you ever heard of this? What would you do if you had the shorter one and want to put duals on it? Thanks in advance. 8)

Have you thought about snap on duals.

I haven't really done much research on it yet. It doesn't really matter which I have. Do you have to have a certain inside wheel for it to work? I've never had duals on anything before so I'm not sure whats involved. Thanks

You can put axle mount duals on either axle length. problem with the short axles the tires will almost touch unless you are settup for 30" rows (60" centers on inside rear wheels).

If you are on wide rows "36" or wider) you can either go with the snap-on duals as the previous poster mentioned or by a set of extensions to put on the axle mount hubs. I had a 656 with the shorter axles. I used the extensions & got along ok with them.

Only problem was they were a bit of a PITA to tighten or loosen. I always took them off when I took the duals off & left the dual hubs on. I had to use a flex end on the socket extension which didn't make for good leverage. if you would leave them bolted to the hubs that wouldn't be a problem but I didn't like them sticking out that far. I would take off the dual, then remove the extension & leave the hub on the axle.

For the "snap-on" type or hub mount duals you don't need a different wheel center. For the hub mount, it just clamps to the axle then you bolt the dual rim to it. On the "snap-on" type duals you remove some of the bolts where the rim claps to the wheel center, put in a different bolt that screws into an "eye". The dual then uses rods with hooks on the end that hook into the eyes. The dual wheel has a "ring" that fits against the regular rim. Rods are thread to tighten the dual against the inner wheel.

Problem with the snap-on type is that there is no gap between the dual & the inner wheel due to the ring. Mud can & will pack in there. Same will happen with a hub mount dual if it's really wet but not as bad or often as the snap-on type dual

If you get axle mount hubs, grease the threads on the u-bolts before putting on/ tightening the nuts.

(quoted from post at 12:42:03 01/09/10) If you get axle mount hubs, grease the threads on the u-bolts before putting on/ tightening the nuts.

Thanks for all the helps guys. I've located a set I'm going to buy hopefully. I've got to scoot in my rear wheels before I put the duals on. It's going to be fun trying to get them moved in. haha
