I wouldn't rebuild one of those tensioners, way too much hassle for me.

Help/ideas? Bobcat belt tensioner?

Thanks for the input, not sure I can afford the bobcat OEM part lol. But I know what you are getting at, you get what you pay for.
Willie, I was kinda thinking the same thing, much easier to just slap a whole new tensioner/idler pulley assembly on there.
So I got the Idler off, there is no arrow plate between the spring and the pulley and the pulley spins freely but not so smoothly, kinda wobbly and bearings don't sound so great. So I think I'm just going to give it a new one and see what happens. New belts and a new Idler/tensioner pulley assembly and see what happens. This thing quit working on me while I was using it and then upon talking to my buddy, who was the last one to use it, I was informed of the prior issues. Would have been nice to know beforehand but oh well gonna get her back up and running in the next week.
Just want to clarify installing everything new. Tensioner pulley is at 1 o'clock under no load and 3 o'clock under full load against the stop. So installing it I pry down on bracket and tighten it around 2 o'clock? Run it, recheck it, and re-adjust if necessary? That arrow should stay between 1 o'clock and 3 o'clock correct?
I take back what I said about the design, now that I have disassembled it, which took all of 20 minutes, its a pretty simple design and not so hard to work on. I was thrown off a bit because at first glance I didn't see the third pulley which controls the fans way in the back hahaha...
oops. I also found the diagrams on the Bobcat web site which are nice to have.
Thanks for the help I might put together a little repair video if i do I will post the link. Here's the pulley.

Yes, you should adjust the tensioner so the pointer is between 1:00 and 2:00. If you tighten it so that the pointer is in the range of 3:00 you're getting near the area will be "bottomed out", not able to provide floating tension on the belt. Less than 1:00 may not be enough tension on the belt.

And yes, you may be dropping some coin to purchase that OEM tensioner assembly, but they do, in fact, last a long time, so as you stated, you do get what you pay for. That OEM belt and tensioner is worth the money in the work they'll do.

I have an 05 S250 that needs the a/c belt tightened, I have resolved to just get used to the noise until it warms up as I cannot find a gnome powerful enough to break the adjusting bolt free, the other choice is to remove the engine. Good luck, someone's wife's nephew needs to get a slap up side the head and send to find a real job, not in engineering.
