Hi I am new to this site and new to the crawler world. I recently acquired Riches 1948 D2 and I have it taken apart for cleaning, repairing and painting. Everything is going good. I took the plate off the top of the rearend to adjust the steering clutches and got them adjusted but I was wondering when I got them adjusted the square end on the adjuster is about all that is sticking out the inside of the locking clamp. Is this normal or okay and is there still alot of life left in the clutches?πŸ‘‹

Thank you for the help
Brian

If you are saying what I think you are saying, there is no more adjustment to be had. The steering clutch adjustment is made by backing the adjustment nut off to let all the preasure of the springs hold the plates together. I might have misunderstood but you could check this out through your manual. Anyway I don't think anyone intentionaly sold you a dud. Good luck. Charlie

Rich its not a lemon I am having a lot of fun with my new toy.

Charlie what I am talking about is there is a locking clamp that holds the threaded rod that you screw in or out to get the three inch stroke at the top of each steering lever. My threaded rod is screwed in to where about all that is sticking out of the clamp is the square end that you put the wrench on to screw it in or out. If it had new clutches would they be in like mine or out?
Thanks Brian

The adjustment on the D2 steering clutches actually works opposite of what most people think. As the clutch packs wear, the throwout yokes move outward, away from the centerline of the rear end. When the clutch packs are thick, the adjustment screws are threaded almost all the way in, just as you describe yours being.

To fine tune the steering clutch levers, sometimes it's also necessary to adjust the large nuts on the other end of the actuator levers that the clutch levers pull on. Between the two adjustment points it should be possible to maintain good lever travel while keeping the 3 inches of freeplay.

I wonder why there is a set of second spacer nuts on my actuator levers?--I thought it was due to wear of the clutches and to get the square end of the transverse adjustment rod more toward the pinion.

Glad to hear Brian. Hopefully you won't end up spending as much as I have on the project.πŸ‘

Tom never said anything to me about replacing those clutches, it may have been done before he bought it.

Thanks for all the help Toby it looks like I am in good shape on the steering clutches. I can not wait to get the D2 restored and painted hopefuly for the 2012 show season.
Thanks for all the helpπŸ‘

It's hard to tell why those extra nuts were added, they don't fit the rounded recesses in the actuator levers like the rounded bigger ones would. Having them in there would definitely position the levers farther forward, but it's hard to tell from the picture how much the clutches are actually worn. Have you tried taking one of the extra nuts out to see if there would be enough adjustment left at the screw to maintain operation?

They are actually wheel lug nuts with the rounded part in the actuator. Since I could adjust the levers to the 3 inch play I just left them in there--steering clutches seem to release Ok for now! πŸ‘

I'm not sure that I understand the steering clutch adjustment. It is my understanding that as the steering clutches wear there will be less free movement at the steering clutch control lever handles. To add more free movement at the controls, the square adjustment rod is screwed out (towards the center of the tractor). In other words, when the square rod is screwed out to its full extent (towards the center of the tractor) the steering clutches are completely worn out. Am I correct?
