Walthers Rotary Plow question

[MrMick]

I am trying to replace the rubber bands that operate a Walthers Rotary plow. The motor rubber band ( I am using some small rubber bands, not a walthers part because I could not find any reference to the actual part that I need) is easy, it's the "thrower" rubber band that looks difficult to install.  Anyone been 'there, done that'? Any help would be appreciated,

Thanks,

Mr. Mick

Try your local dentist's office, take your old band with you for sizing, they are used for straightening teeth.

Hi Mr. Mick:

Edit: Ed has provided the diagrams for the Walthers rotary plow below. My post was about the Athearn plow.

Hi, MrMick

I must have been lucky since I still have the factory bands on mine!

Here is the reference sheet but, as you say, there is no mention of replacing the bands (O rings) . It looks like you would have to remove the slinger wheel and then the three screws behind it? [edit] see reply below.

 

Sorry I couldn't be more help.

As Dave Mentioned, I also put a decoder in mine and run the wheel fairly slowly. Still, the rubber or neoprene bands will still rot simply by being exposed to oxygen.

Good Luck, Ed

 Look at the second picture. The section with the idler shaft is separate from the blades, 2 screws on the bottom release it. With it off, put a band on the pulley attached to the blade shaft, and then reinstall the idler support. Work the band over the small pulley on the idler shaft.

Curiosity got the better of me and I opened my Rotary.

The bearing mounts for both shafts are cast solid with the floor. The screws shown in the drawing are for the shell.

I notice that all you have to do is pull slightly forward on the "rotary head shaft" and there IS enough of a gap that the band will slip behind the shaft.

No further disassembly is needed, just the four screws, and the two struts off the shell, and remove the shell.

Good Luck, Ed

Hello all,

Rather than a rubber band how about an "O-ring"?

These come in many different sizes both thickness and diameter.

Check out your local hardware store or home improvement center. It won't have as much stretch as a conventional rubber band but it might prove more durable.

Hope this helps.

Absolutely!

The originals ARE O-rings. 

As I mentioned in my first reply. Mine look like new but they are going on 20 years old!

Cheers, Ed
