Dosko 27 grinder belts.

[lux]

Anyone else had issues with dosko grinders eating drive belts or throwing them off the pulleys ?

Idlers are new. All bearings are good.

Can't visibly see why it should still keep doing it.

Is this the small hydrostatic drive belt?

[lux]

No , that one is fine. It's the two grinder wheel belts on the outside.

[Al Cormack]

Have you got the pulleys with the lip on the outer edge to stop the pulleys slipping off?

If you run the machine without the guard on you'll see the belts working their way to the edge.
Re-aligning the pulley can help.

The idlers in the middle def have a lip. Can't remember about the main pulleys at either end. Are they supposed to have a pronounced lip as well?

No, just the idlers.

Mine was doing this regularly and Danequip took the mount off for the idler and welded it back on sloping back slightly. Not had a problem since.

Would you happen to have a picture of the modification or know how many degrees they set it back by ?

[Al Cormack]

I'm won't see the grinder until Tues to take a photo.

It wasn't changed by much, but just enough to stop the belts moving to the edge.

No rush. If you get chance would be appreciated. Cheers.

You jinxed me! Bloody belt went this morning. First time in months!

Having looked closer at the top idler bearing mount I would say it's been wacked with a big hammer to bend it back slightly.

Did the job though.
