beautiful machine
you have there. i'm not sure what you mean by the agi coupler, i don't have a lot of extra parts for rollermatics but one of my machines is going to be a parts machine as the tubs are rusted out.
mark michaels, who i did get a ton of stuff from last year might have it, i will talking to him soon and can ask him if i know what it is. is it the ball coupling that connects the agitate shaft to the mechanism? | ||

let me do some checking here
and i will talk to mark.
here is a pic of the transmission from one of my machines, either a 67 or 68 model, can't remember. is it the same as this one. if so i will send this pic to mark, he also has that guy he buys from in pittsburgh, the one i got the water and oil bellows and tub seals from. mark says he still has a lot of stuff. i didn't know the ball coupler went out, great, one more thing to wear out on these great old washers! i will get back to you on it.

.
The lash is adjustable on the Rollermatics that I have worked on. Don't know about the model Chris has though. I think if it were to be left with too much lash, pounding away for a number of years, the joint would be too worn to adjust.
Here is a pixs of the Rollermatic that I just installed in a machine. You can see the adjustment set screws. Those are loosened, then take the joint apart by unscrewing the "plug" on the bottom, and inspect for wear/damage, then lightly oil the plastic insert in the joint, and reassemble. Do not tighten it too tight! Then replace the retainer and set screws.

thanks for the above
info (rickr) on oiling that joint. i have never taken this ball joint apart on any of mine.
i see in the above pic that your transmission has the earlier style rubber coupler like the one's on my 65 machines. when i first started tearing into rollermtics last year i was surprised that they used 2 different style agitator couplers. | ||

well like i said any help with a new part would be awesome.. the prob i have is that i had done a rebuild on the machine months ago and all was fine. machine ran fine. then it started to knock on the down strok. i took the upper end apart to make sure all was good there no probs found. took the lower end apart nothing is hitting or binding up. when the machine is running dry or on slow speed all is fine, but on reg speed agi with water in the tub it will knock when it starts the down stroke. all i can think of i the coupler is wearing and causing play. i had a rollermatic years ago that was fine till one day while running it started to sound funny and in the mid of a stroke the coupler broke and the arm then caught the pump housing and crunched the pump cover. any ideas im more than happy to hear them i just cant figure this out

Actually
I have tightend those pretty tight in the past to get the play out and they have run for years. You want it to resist slightly on slip around the ball with absolutely no play in the joint. I have never seen one wear out yet we are deeper into the future now so it could. There are two delrin washers inside there that the ball slips around, they were molded for this part and are the only material GM could find that would resist the pounding this joint takes. But the delrin will wear out eventually it is a plastic after all.

i checked into a box of parts i bought last summer
from mark michaels. i did find that i had bought a ball coupling from him which means he may have more of them.
this one will fit the rollermatics that use the metal ball coupler, the one that looks like an acorn. at least the instruction sheet that came with it shows it attached to such a coupler. it may also fit the earlier models which have the rubber coupler, that i'm not sure. it has a ball and a nylong sleeve the ball rests in, and a nut ring that is screwed on and is adjustable as we all know. the ball itself will screw into a threaded nipple that is attached to the coupler. i have the instruction sheet with it which includes the part no. i can supply this info if you like. i spoke with mark last week and will prob be talking to him soon again, i will give him the no. and see if he has any more. i also know he has 10 oil and 10 water bellows in for rolermatics, 35 bucks each. not a bad price i think. the bellows pliers he is listing for 35 bucks as well on his e bay site. thought you may be interested in this potential source for a new ball joint. | ||
