Extra belt drive belt?

[Vern]

Looks a lot less involved than my mvm belt drive on my ascender, and I managed to change that one on the hill in a blizzard. Axle nuts look to be the worst part of the job if it is truly necessary to remove the lower pulley to swap the belt.

No it doesn’t look hard with a box full of Milwaukee tools and a warm shop. Now try that with out power tools at -20 in a snow storm cause you know that’s when it’s going to break.

Thanks for the video!

That was my point. Cat stated the belt as life of the sled. Can it break? Of course, but not a job mountain side for the vast majority.

That is what I was wondering it looks like you cant get the belt off without removing the lower gear. I thought you could slide the top gear off but I doubt there is enough slack. If the top gear didn’t have an inside lip to keep the belt from walking off then you could.

The poo belt drive needs to have both pullies removed and installed at the same time when changing the belt. some times is a @#&% and some times the stars align and its easy

Do you really need to remove the bottom pulley?

Well DD that’s the question I am asking

Can you rotate the cross shaft to make the center to center distance shorter, like if you were putting different gearing in? or maybe it would be too hard to get thing tensioned up again.

I am pretty sure that is how you are supposed to do the new cat belts. I want to say I watched a video at some point and it looked super easy to do. The eccentric bearing for the gearing adjustments probably had ease of installation in mind too when Cat designed it. Way easier to do than the Polaris. I have done a Polaris quick drive belt on the hill and they are a PITA if you do not have the tool to spread the pulleys apart with the belt on there.

Check this video out:

I think you might be able to get the belt off without taking the bottom sprocket off. The guy in the video took it off for a track swap.

I’m thinking that the eccentric only moves a few thousands maybe 5? Just enough to loosen the belt. I am asking this question because there is no sense in carrying a spare belt that you can’t change or carry the tooling you need to do the job. It looks like no one has had to change one yet and that’s a good thing.

suppose i could actually try to change a belt after having one of the sleds for over a year.
