  • Shock bumpers

    Rebuilt a clutch last night, and the trip arm seemed to be tight, it would double feed. Mostly at the 1. Played with the spring tension to no avail. It seemed to me that the binding was farther back with the stop blades. The arm holding them seemed loose so I compared it to another machine. Noticed that machine had a bumper in it. Checked all 48 and found 23 of them had no bumper and the nut and bolt going thru the bushing were tightened to take up that extra space. Is this a modification to take that bumper out? or did someone think the nut and bolt were too lose after ther bumper deteriorated and fell off.

      What's the advantage to taking the bumper out? And how much clearance should there be? Should the arm have a little play back and forth, or just be loose enough for it to swing freely?

          I use a Plastic washer and shorts sleeve and metel washer. When you tighten up the bolt going through the trip support against the sleeve the plasic washer becomes concave and acts like a cushion when clutch comes around to the trip levers.

            there is supposed to be a sleeve, a plastic washer, and a metal washer, if not, then it is not correct.

              the Longer "Washer/Bumper/Washer/Trip Arm" is the Old/original way. The "Washer/Plastic Sleeve/Trip Arm came later.
              unless they have been already changed. the dists with the bumpers have a funny one piece welded trip arm (thingy with the 2 Nylon Rollers which trips the trip rod) while the others have the modern looking D-Weld with ball and joint cable

                  If you have cables instead of shafts (trip) I would suggest bending the tab on the coil spring at the end of the rocker shaft to reduce counter pressure. That is designed for the heavier trip shaft. the cable is not as heavy, and needs lesse counter force. Also, make sure you have no burs on the stop blades (both trip arm and clutch, but most occure on clutch) file them smooth, and make sure you lube the blades well. I like to see minimal pressure advance the dist. to the next bin.
