  • Distributor is waaay to stiff when retracting

    Seriously I don't know how this one got a hold of the blue pills but they are doing a number on it. This isn't at my center, but it had me going crazy trying to figure out. Left to right is fine, its the retracting and forward travel that is super stiff. here's what I checked so far:

    * The eccentric rollers are not stuck/too tight because they are all set at "0/max distance away from the carriage"
    * The trip rocker weldment is not catching on the indexing cam, or anything else
    * the cam and pinion are not out of time are not dragging or binding
    * the distributor belt has been centered and all carriage rollers are free spinning and clean. its a new belt
    *The "foward/reverse" aluminium arm is not tight at all and when disconnected from the trip rocker weldment is free and clear.


    Here's the symtoms and concerns I noted:
    * old style pinion with the slotted bushing and the timing mark punched in. lots of grease between pinion and bushing
    * no problem retracting with driveshaft disconnected. What I mean is when you retract the carriage, the cam, pinion and everything spins...the belt doesn't "stay still" like it should
    *the carriage is rubbing the frame on the 7 pin side where the one ungrooved bearing is (how the hell does a carriage tube get too wide all of a sudden?)
    * The clutch plate is a little bent up
    * the trip rod (not a trip cable) starts to flex insanely when it gets "tight" on the way back, so bad that one of them had to be replaced...after i forced the carriage back...oops.
    When you know what to do, everything is easy.

    The wire pin guides on the carriage aren't rubbing against the guide supports by any chance?? Have had that a few times on my dizzys

      Nope. and the carriage isn't hitting the belt runner or the stupid long like 4" bolt that goes through the guide supports either. everything seems free and clear until you put it all together it doesn't work.

        Two possibilities for me are..is the new belt rubbing on the chin strap if not could you just try your old belt for chits and giggles to see if it goes away

            I thought that was funny.

            Are any of the bearings bad- WD40 in them does wonders.

            This is interesting. Is the belt installed incorrectly around the belt guard instead of through it? I think Keeth was hitting at that one.

            The clutch should not be bent at all. I have never seen a carriage tube rub the casting, that is an indication something bad is going on here, somehow it seems maybe the carriage is so bent or beat up it is now out of square, that is never good. I have trip RODS here but I have never seen one try to flex especially on the way back which suggests to me that as the carriage is trying to retract it is hitting something causing it to stop and causing the trip rod to flex. I know you said it is not binding on anything but then how is this happening?

              If the white rollers are so loose the carriage can slop all around. (maybe why it's rubbing the casting) I've seen people trip or step on or even fall on and cause some funky things that don't fall under regular repair thoughts. Take the carriage out and roll the tubes on a flat surface (see if they are bent) and maybe in the rebuild you could stumble on to something.

                  I actually had a problem where i would adjust the eccentric rollers to where they should be and the carriage would not telascope so i took the carriage out and checked the tube it had a bad bend it i replaced it put it back in it ran like a dream

                    I only count 1 there Keeth. that was my first thought but "it was working fine before" before being a clutch rebuild and the distributor eccentric adjustment. I'll re up that into the suggestion box

                    Nope checked em all and found them to be in working order. not the cam followers getting stuck in a shimmed out/warped indexing cam either its not a slight drag is a whole hand pull.

                      Is there a specific point where you feel/hear it start to bind? I would stay right at that point moving it back and forth while looking everywhere you can think of.

                          How about the cam rollers? Either stiff and not turning?

                            Are the carriage tubes bent?

                              perhaps the carriage tubes were bent. I spend about 4 hours taking it apart and checking all the bearings and everything I'd seen before.

                              The belt was tracking off the roller a bit and binding up on the comb looking bracket with the belt spring on it. aligned the big white rollers the belt runs over and it didn't have any effect.

                              Somewhere, there is a bind that is causing the trip ROD to flex...a lot. and I don't think its the carriage tube since both ends attach to the carriage
