Snowblower/idler pulley problems

I bought a snowblower attachment for my 1967 Suburban 10 several years ago. Just tried to get it set up on my tractor recently. It mounted to the tractor ok except the pulley doesn't line up properly with the engine pulley. The outermost/smallest pulley coming off the engine almost lines up, but it doesn't provide enough rpm's to throw the snow. I'm beginning to think this snowblower was intended for the Custom series since the fit is close but not exact. I need to figure this out or sell it. Any suggestions would be appreciated. Thanks.

Second problem is on my 1968 Suburban 12. The pivot arm that the idler pulley for the drive belt attaches to has way to much play where it pivots when the clutch is engaged/disengaged. There must be a lot of wear or a bushing fell out. Anyway since there is so much play the pulley doesn't stay in alignment when the clutch is engaged and the belt pops off the idler & engine pulley. Anyone had the same problem/know what the fix is? Thanks again.

Hey Marshallgang, My snow blowers are 1976 vintage, and I don't know how close that is to the 1967, but I moved my blower back to the front of tractor as far as I could, then bought a slightly longer belt to use the centre pulley, they will never work as well as a 2 stage blower, but in dry snow it works great. The belt popping off is controlled by the pulley guard if in place, it keeps the belt on, and there should also be a guard on the blowers driven pulley, as well a small round stock guide on the idler pulley to hold the belt in place. I don't believe there is any sideways adjustment to line up the pulleys, thus all the belt guides they have. If this info is irrevelent, send me maybe a few pics, and part numbers or manuals so I can see what you've got, and maybe we can come up with a solution. Good luck sgdorcas@accesswave.ca

Thanks for the response. I found a link from this site to Sears part numbers. I was able to find my snowblower part no. There & confirmed it is for the Custom series of tractors. I didn't do my homework & the guy who sold it to me took advantage. Maybe you can help with the idler problem. I talked to a Suburban owner (late 60's era) & he said the idler pulley bracket getting sloppy is a common problem, that I need to replace the bearing which requires cutting & rewelding the bracket. I guess I need to get the bearing & take it somewhere to do the cutting & welding. Seems like they would design it better to allow for replacement.

On these tractors, there are several idler pulleys, and all are of the same design, if not same size. I've had trouble locating the correct pulleys in the past, and drilled of the weld spots, replaces the bearing, (Local stock from any commercial bearing vendor), reassembled with nuts and bolts. I have one that was done ten years ago, and works fine. The problem with welding is the possibility that the heat will destroy the grease seals in the new bearing. Good luck, Grant
