distributor

[eagle]

can anyone tell me why a distributor will rock back and forth when it arrives at the three bin position,it's even worse if there is a pin half way up the belt.

Re: distributor

HMMM.... 3 pin ? ...or 2 pin???
I've never seen one do it at the 3...
if it's at the 2...clutch is too tight, or the bushing inside the pinion gear needs cleaned & lubed..or the pinion gear itself is
grinding on the sleeve inside it.

Re: distributor

Eagle: is the Dizzy rocking when the laces roll over the roller? Ive noticed that myslef. That is normal if that is what its doing. Other than that if its the 2 Pindecked has the right idea. Other than that your belt measurement might be off. Thats all i can think of.

Re: distributor

Also, check the Dist Drive Weldment. If it's bent or worn, you'll get that rocking thing.
If this is on an odd machine, put the dist in the #1 position & see if the drive shaft is bottoming out. Turn the roll pin to the slot in the u-joint & try to slide the shaft away from the dist. If it won't slide out at all, you're bottoming out. We have found that the short drive shafts will work fine in most machines but if you cut the u-joint end off at the hole for the roll pin & drill a new hole the same distance from the end as the original was, they will work in all of the machines.
Why some machines are different this way, no one has ever been able to figure out but I've seen this in more than one house.

Re: distributor

Take both lateral springs off and check the length of the safty link shaft. If it is too long it will bottom out in the tube and cause the problem you've described.
Also check the needle bearnigs in the main casting (the one that sits on the post).
Sorry deadwood but rocking motions in the distributor are never "normal".

Re: distributor

Are you using the thick or thin belts? If its the thick belts call Tom Stahl @ Stahls 70's he raddled of to me once how he over comes this problem. Did'nt pay much attention since IM presently on the 30's.
Hope he can help you out!He knows his stuff!

Re: distributor

I Had one Distributor that had a problem like this one, and i did every thing i could think of. then i took that Distributor off and put it on another machine and thats when i found that the Saftey Link Shaft was bent.
after replacing that.it was fine.try this and see what happens. also the saftey link spring can cause the same problem
let us know what you find

Re: distributor

My limited experience also leads my best guess to the safety link.

One word of warning, ensure that the link length is set correctly. If you find that the safety link is bent, replacing it will only buy you a few months until it bends again. The length should be 3" or less from the end of the rod to the closest face of the locknut.

I've had to replace or shorten more than a dozen of mine in the last 6 months alone.

Good luck...

Re: distributor

Dutch,
Thanks for the hint on dist. shaft length. I found three that were too long and removing 1/2 inch really stopped problems on these machines.

Glad to be of assistance.

Re: distributor

Dutch,

Just to ease your mind on why some machines are this way...It is sometimes due to improper installation...The frames get bent big-time.

Another problem this causes, is that you can't get enough tension on the PW belt if you install a regulation smaller pulley to slow down the pinwheel.

A few other possibilities that will cause wobbling...

Worn rod end(s) on the safety link.

Stretched or improper springs under the dist yolk.

Bent drive shaft or bent BE motor shaft (for drive shaft) caused by to many PJ's

Tech

P.S. I have found this problem mostly due to bottoming out of the drive shaft also...Good Call Dutch

Re: distributor

We all know that the timing marks on the pinnion gear and the large white cam gear should line up. If I get a swinging dist sometimes I have moved the cam gear one tooth forward or one tooth back and cured the problem. Good luck guys.
