Hello, I am new here, so please forgive me if I don't do this right. I just purchased a 1968 Allis Chalmers I600 with a front loader and a backhoe attachment. It's got a deisel engine that runs well & everything works great except the clutch slips when trying to scoop up dirt with the front loader bucket. I am an RV technician by trade & run my own repair service, but everything on this unit is completely foriegn to me. I do have a service manual and from what I can see, I think the problem is in the shuttle clutch. The clutch feels good in reverse (although I haven't tried it with a heavy load), but the handle feels a bit "funky" when in the forward position. I see in the manual there is a way to adjust the clutch with shims. Has anyone else here encountered this? Am I on the right track? Any helpful suggestions would be greatly appreciated. Thank you. Tim

I have the same basic tractor without the backhoe attatchment. Mine is doing the same thing,it will move in reverse but will not hardly go forward. I started taking mine apart then got bad weather and had to stop but finished pulling it apart today. I found a manual online which has helped me pull it apart. I pulled the shuttle clutch out today. I"m going to take it around tomorrow and see if I can get someone to rebuild it for me. call me id like to talk to you about the tractor. tony 505-891-8638 or505-410-3115.

Today I went out and played with it a little more & now I'm thinking the big problem (maybe the only problem) is the engine clutch. When I put the tractor in 4th gear and release the engine clutch, it tries to move, but just sits there slipping. It does the same in both forward and reverse. On closer inspection I see a little bit of oil dripping from the bottom of the engine clutch housing, so now I'm thinking that this clutch is wore out, soaked with oil, or both. I'm starting to think about pulling the engine to replace the clutch & fix the leak, but my concern is not being able to find parts. In my parts book I see AC #0247745-3 for the pressure plate assy & AC #0245834-7 for the disc assy. I have done an internet search for these numbers but have come up with nothing. Does anybody know of a good place to find old AC parts? There's not much point in taking it apart If I can't fix it. At least if I leave it the way it is, I can always tow it to the spot I'm working with my 1949 Case and still use the backhoe. LOL. Tim

The I600 is based on the D15 tractor, and the industrial was first called an I60, renamed the I600 in 1966. I would imagine the clutch parts would be the same as the D15, available through any dealer, now AGCO. AGCO is based in Duluth, GA, dealer locator at www.agcocorp.com. Shuttle should be behind the access plate you show in the picture.

Where can I get an shuttle clutch assist for a allis chalmers 1966 I 600 bachhoe, new or used. Where can I have my old unit rebuilt? Does the D15 use the same shuttle clutch assist? I would appreciate any help that you can give me.

Thank You,
Rodney Johnson

By 'funky' do you mean that it goes into position easier than going into reverse? To me that would indicate that the forward clutch plates are worn more than the reverse ones are (logical), so by removing some shims you tighten up that forward clutch. I'd follow the manual advise. The shuttle is similar to the Power Director on the D series tractors- if the PD doesn't have a firm snap going into position, the clutch needs adjustment. Likely there's a side access cover on yours.

Thanks for the reply. This reinforces my thoughts on the problem. You are exactly right about it being easier to go into forward. It almost "falls" into forward where-as there is more resistance going into reverse. As far as access, there is a plate on the right side of this clutch area (see picture) with 2 steel lines going through / into it there. I'll study the manual a little more and see about compensating for wear by removing a shim or 2. If I can fix it that easily I'll be thrilled. I got a good deal on the tractor ($2k) due to this problem. Tim
