Bomag wacker throws its belt off

[Ian H]

This has been at work for years and I wouldn't mind borrowing it, permanently.

I seem to remember that it throws its belt off when used so wondered if it might be missing a tensioner or other part?

Thanks

Could it be that the belt is slightly stretched? Isn’t there a better one you can borrow permanently?!

At work someone nicked a laminator. A new one was ordered. Several months later, the new one went missing replaced by the broken old one!!

Isn't it the wrong belt? That belt is toothed, but the pulleys don't look toothed from the angle shown.

That's the only one but there is other stuff.

It could be, the bolt in the middle seems a bit big for holding the cover on so I thought that might have been a tensioner. But I can't find any images on google.

Does this help?

I recon the bolt in the centre is just to hold the cover in place.

Yes, I see it has no tensioner so chances are the belt is wrong or stretched

Send an email to this bloke telling him what your machine is and he should be able to sort you out with a new belt.

Yep, no tensioner...

And the belt in the video is toothed, too. Spare parts here...

Thanks very much

Worth checking/changing the gear oil, think it's called the exciter

Looking at those drawings, the engine mounts are on elongated holes - slacken off these mounts, take up the slack, re-tighten.

When you get the new belt on, check that there isn't any wobble on the bottom pulley which could indicate a shaft running out of true.
A toothed belt is able to turn on a tighter radius than a normal one, and can be run nice and tight.
