for u 30's mech's

I use to hate changing the 604 arm bushings or even worse when the stud bolt would break on the 604 arm. What don't you like about the 30's

Re: for u 30's mech's

The hardest thing I ever did on the 82/30 is replace a carpet. IMO, I dont think there is a job more tougher then that. Of course, I have been working on them since 1965!! An older machine, yes, but I enjoy working on them, but isn't that what it's all about??

Hey Andy-M. Now that you stirred that memory you are probably right. Pulling that rear roller out especially when it had a carpet drive pulley with the center hub was a big pain in the "A". And don't forget the bounce plate if you had ball door's.

Re: for u 30's mech's

Hey "X"..never believe what i had to do today...bearing on rear roller froze and cut thru the shaft! At least I get that R&R'd without removing the carpet or bounce plate...and yes..I do have Ball Doors..!!

Hi Andy, Sorry to here about the rear roller shaft. How big is your center? Have you done any modifications to your machines.

Re: for u 30's mech's

Rear carpet rollers are the worst. You virtually have to loosen everything just to move it around. I recently had to take one out because it had ground the whole out on the ball door side. I had to remove everything (including the plow) just to get to the whole so I could rebuild the side of the machine to properly hold the new shaft. (The old one had been riding on the metal sooo long that is cut the end of the shaft to only about 1/2 inch long-too short to do anything with) This is only the half of it.

Once I got everything back together, I had problems with the hub & pulley. This has to be the worst design - a hub on a shaft that tightens when the pulley is tightened down(which must be done is such an exact way or else problems). Problems is exactly what I'm having or was having. After having two rear rollers shaft get knawed off by not getting the hub & pulleys on right, I have taken a cue from the 82-70 design and made a piece to replace the hub! It mounts onto the shaft with set screws(only have to grind the shaft so there is a flat spot) plus is mounts easily with the pulley and also allows for the mounting of the kicker pulley shaft. I'm REALLY proud of this little invention of mine. The advantage of this over the 82-70 design is it allow the larger pulley to line up with the drive belt and also allows the kicker pulley to be adjustable - not like the 70's fixed design.

Welcome TenLubak,

What's the difference between a /30 and a /70 rear roller?

I don't know.

The 70 rolloer has a longer shaft than the 30 and has a flatened "side" on the shaft.

Thanks for the welcome.

Re: for u 30's mech's

Oh...,

I will have to rebuild my 24 rear rollers then! I did put in the /30 rollers from my /30 machine into the /70 machines we have now . And about the shafts: I make them myself including the end of the(pully side)of the rear roller. Maybe if you or others are interested : we are busy developing a round support for the rear roller bearing instead of the half moon(on the ball-lift side,mounted or welded(rather see them mounted) on the machine plate), we did try this on a few machines for some years(/30 and /70)and no shafts did have an early goodbye since.
Will keep you posted about that later.

Martin

And an extra edit : we did cut our shafts (/30 and /70_)about 3/4" shorter a long time ago.

Re: for u 30's mech's

I've got 16 30's and 16 70's
the 30's rear frame is 1.5' under the walkway in the back, there closed pinwheels
try reaching for the rear roller!

Re: for u 30's mech's

I always disliked changing a pit that had the old center roller. Especially when the bolts were frozen up or rusted up. Of course replacing the stationary rear roller mount does have its claim to fame as one of the "meanest" jobs on the machine.

Re: for u 30's mech's

Bud Yep!!! I love these old girls. To bad they are almost a thing of the past. But I have heard that a company up in Canada is installing 30s for people. I just might have to head up that way and do a little work. Has to be cheaper to live there than in Southern California.
