  • Dist. hesitate to 7 and/or 10

    I have a distributor who hesitates when moving to the 7 and 10 position. I have changed the dist.belt, clutchplate and checked all bearings and lubrications. By thightening the spring on the clutch i got it to move properly to the 10th but it still hesitates before the 7nth. It has no problems between the 2 and 4 either. Any ideas?
    What gets broken must get fixed! By me....

    Frode, Check your dist drive shaft. You may have a worn out u-joint, balls at end of drive shaft may be worn, also check the drive shaft housing on B.E. motor.

    If your linear spring is stretched too far you may have too much foreward tension. This will cause hesitation. Your clutch tension should never go beyond 1 full turn. I have also found some dist belts will cause stalling in these areas. Are you running a thich belt? If so try a belt from another machine.


    One more thing, make sure you cut your belts to the proper length.

    Good luck and keep us posted

      Clutch Plate has most of the common ones covered...

      Make sure the distributor isn't very slightly rubbing against the wheel at the corners... that causes bounce and hesitation, too.

      Also check the nylon camwheel and followers... make sure that when the dist. is at the corners, the followers are riding fully on the camwheel track.

        Look at your {White) index cam, watch the inside cam followers to see if they are catching a spoke as it is traveling. If so, shim accordingly.

          Along with the above suggestions, check to ensure that the safety link spring is not rubbing against the distributor support weldment. If so, also shim that accordingly.

            take the belt and linear spring off and make sure the carriage slides freely, also make sure none of your white nylon belt pulley bearings are stiff causing it to pull the dizzy back or push it forward

              Another quick one to check:
              The Dist. drive shaft bottoming out on the dist drive housing.

                <font size="2" face="Verdana, Helvetica, sans-serif">Probably not as it's at the 4-7 where the drive rod is furthest away from bottoming out. Closest area to bottoming out is the 1-5 positions.

                  Another thing to try is to simply clean the eccentric tubes look for burrs. Apply a light film of oil.
                  Check eccentric adjustments. A very slight adjustment may make all the difference.
                  I would try Holding the eccentrics one at a time and move the carrage tubes back &amp; fourth. If you can't hold the two top ones from turning or you cant turn the eccentrics when holding the carrage tubes in place they are more than likly to tight.
                  Make sure the Carrage tubes are running parallel with the trip arm.
                  I also would check to see if the Distributer stalls in these positions with out pins - Tripping it by hand. Let us know how you make out.

                  Good Luck, Kevin

                    -U-joint
                    -Dist rubbing against pinwheel
                    -something rubbing between front half of dist and rear when dist retracts.
                    -safety link rod end

                      This may open up a whole different discusion, but I noticed that Kevin said to oil carriage tubes. I keep mine as dry as possible, I mean thats why the rollers are made of nylon.


                      What do you guys/gals do. Oil or No Oil???

                        Too much tension on the eccentric rollers and not enough on the drive clutch.

                          <font size="2" face="Verdana, Helvetica, sans-serif">No grease or oil here. The grease just dries up and causes binds. I only lube bushings, and bearings on the distributor. So far no problems.

                          I also replace all tubes that have any dents. They tend to create problems.

                            On another note I had about 10 distributors with the metal style concentric roller (the one that grounds machine) All they were doing was grinding bottom of tube down and there were shavings all over the place. I took the nylon concentric and ground it down to the size of the metal ones and it works great. They dont even sell the flat nylon roller anymore. I havent had a problem with scoring.

                              I was told that the depressions in the tubes were caused by dust getting on the tubes, and then being ground against it by the rollers, kind of like miniature files or sandpaper scraping at it year after year.
