drive belt plate thingys

Where can I find these drive belt plate thingys? For some reason when I hit reverse the belt comes off track, and the mower didnt come with these plates. I figure that should help?

It's actually the bolts that hold the gaurd in place that keep the belt from jumping off. The bolts are usually so close to the belts and pullies that the belt can't jump off. In any case you can get the belt gaurd at the dealer for your mower. What kind of mower is it? There may be a place "on line" if you don't have a local dealer.

You SHOULD be able to get them at any Bobcat dealer's parts department (assuming its a bobcat you are working with). They may have to order them, but you can get them. It MAY help keep the belt on, as do the bolts holding it on.

Does it force the belt off while you're driving in reverse? Those guides and bolts just keep the belt ligned up while it's slack.
If it's coming off under power it's probably because something is not ligned up.
I'd guess the idler pulley is either bent out of alignment, the bearing's shot or it's just completely worn out.

It always does it if I pull the mower backwards without being driven in reverse. If I drive the mower in reverse theres about a 25% chance the belt still works its way off. I took a pic, I pulled the mower back about 3 feet in neutral and sure enough the belt started working its way off.

It looks like the bottom guide is bent a little, but it doesn't seem to me like thats the problem.

I agree.

That looks like a flat serpentine type belt and not a v-belt? Is that right?

I would check for wear in the PIVOT POINT bushing (that would be the pivot point of the PLATE that the idler pulley is mounted on)of the idler pulley as well as the pulley bearing.

Its a dual-belt drive, the right belts are on there, they are a little old though. Just got in, I'll pull that assembly apart tomorrow and take a look.

Isn't there some sort of adjustment on that? It seems like the green pin should come back and up a bit (right toward the camera) so it would be closer to the 11-12 o'clock position on the pulley. It could be just a tad bit closer to the pulley that way, also...giving it a tighter tolerance for the belt.
If it doesn't adjust, you could simply re-drill them to fit closer.
Another option would be to put a sleeve on there that would slip firmly over the pin. A piece if brass or something like that.

fill the left tire 5 psi higher and it should keep it in the track until you get a new plate.
