Dist wobble at all bin positions

[ST-21]

This is what is happening. The dist has a lot of wobble at all the bin positions. most at 4 and 7 least at 10. Its like side to side wobble. I have cleaned the clutch, checked safty link length, put on the shortest drive link i have(any shorter and it falls out of the backend motor drive hinge), dist support bracket is tight and level. I checked the the U shaped bracket that the dist drive link goes into and it was worn pretty badly, did not have a brand new one on hand so i had to put a less worn on, but the wobble is still there. My question is. If that bracket is worn, would it cause this type of wobble? its worn mostly at the front of the bracket (closest to the motor). This makes sense to me since the drive link is at that position at 4 and 7 and away from where its worn at 6 and 10. Does this make sense or am i crazy.

Re: Dist wobble at all bin positions

Oh yeah, changed dist and wobble was still there. The wobble has not cause problems yet but I dont want to take that chance. It will take a few days to get a new bracket since I am not allowed to order parts so I figured I would ask to see if i could get my question answered a little sooner, or trying something else on the dist to see if that bracket is not the problem and im overlooking something.

U R right about the U shaped Bracket,but did U also check the universal joint? This can be worn out also or put some thick grease in it.

Could check that the two brackets that hold the b.e motor in place are tightly bolted onto the side of the machine. Play in these can cause the swaying distibutor problem also.

Sven, I did check the universal joint. It's in good condition and the boot is not very stiff. Alastair, never thought about that. Will have to check that out when I go back in to work.

ST-21--sounds like you found the problem yourself--the drive link on pit motor. Ya gotta keep the link and balls on driveshaft greased pretty good or they wear out fast. Also check dist turnpan and make sure pan is not rubbing pin wheel at 4-7 area.

Try checking your two springs on the distributor rear lateral may have gotten weak. If you don't have new ones you can hook a kicker spring inside of the large left hand spring on the safety link and hook a linear spring from the inside of the large spring across to the right hand spring.

Re: Dist wobble at all bin positions

I have 1 dist that has the same wobble to it. I've checked out or changed out everything mentioned here & a few other things. Been half-heartedly trying to figure it out for 2 or 3 years. It's one of my best running distributors so it isn't very high on my priority list.

If by "U-shaped bracket" you mean the 'dist drive housing', those can be moved from odd to even machines (& visa-versa) to double the service life.

How about taking a good look at your dist. drive shaft from the motor?(with everything off does the dist. motor shaft wobble?)...Also; if the pin wheel motor gear is wearing and or without oil it will cause the B.E. Motor to Jerk.(which may effect a dist.)

Dutch;"Been half-heartedly trying to figure it out" I've been watching a dist. go back end forth(Up & Back) at the head pin position for about 3 or four years///I assume its belt lenght...But It Doesn't Give Me Any Problems. [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

Re: Dist wobble at all bin positions

You said the drive link had alot of wear. Did you check the 2 balls that ride inside. If the drive link was that bad, I'm betting them 2 balls had a flat spot on them

[ST-21]

Re: Dist wobble at all bin positions

Oh the two balls Were fine. I use lots and lots of grease on those. But will have to check out the backend motor itself more thouroughly now.

Re: Dist wobble at all bin positions

Make sure that....

The distributor output shaft in the BE gearbox isn't bent.

The distributor drive housing isn't bent, spreading apart, or twisted.

The pin holding the two balls sit on the drive shaft isn't worn.

Re: Dist wobble at all bin positions

take 4 strong zipties to the machine, fill the saftey link sleeve with thick grease so it acts like a shock absorber, lock up 50% of the saftey link springs coils and lock up 25% of the smaller springs coils with the zipties

this will cure dizzy wobble at long entension in 95% of occurances.
