The bolts are all just barely long enough for a full nut, so no room for springs. Perhaps it has internal spring like you said OR they used wrong bolts also. The PTO shaft came from China and had its own booklet with it (all Chinese )
photo of slip clutch assembly. Other than short bolts and no springs it looks like any other slip clutch to me. My owners manual shows the external springs, addresses how to tension the springs also. No mention of this type of clutch assembly. I guess I will have to see what KK has to say in regard to my inquiry. At this point I don't know if tightening the bolts here on this one puts more tension on the internal spring just like the external spring ones. I have no reference as to how to adjust it unless you do just like the external ones. I guess I will find out when I get a chance to use it.
I went back to Atwoods and talked to the salesperson &looked at a brochure. He said they have two types of PTO slip clutches. The yellow ones have the springs and the black one (the type I have) have internal tensioning. If you look at the photo, mine has an extra plate as seen on the left side in the photo that the spring type doesn't have. I think that must be the bellvue washer that applies the pressure. According to the sales guy, it is pre-tensioned and should not require any further adjustment. I hope to be able to try it out in a few more days. I need to hook up and measure the shaft length and adjust if necessary also.
Careful James her old man don't get a jealous and put you in their next demo tiller video instead of the bricks ! :laughing:
