You have to see which pulleys are not in alignment and straighten them, You can't straighten a belt.
the pulleys that the belts pass thru are misaligned.
It could be the presence of water on pulleys causing the belts to slip. If it is persistent then this is a sign of worn-out or misaligned belts.
If the belts were misaligned you would have more problems with the belts slipping or falling of. I think it sounds like you may not have enough slack. When the belts are tightened you should have say a few mm slack where you can tug the belts up and down with your finger.
What are the headlights doing? Is the bulb burned out? Are the lights not coming on at all? Are they misaligned?
The seat belts probably need replaced.
If your snow blower is burning belts, it could be due to the belts being too tight, misaligned pulleys, worn out pulleys or idler arms, or excessive debris causing resistance. It's important to inspect and address these issues to prevent further damage to your snow blower.
Misaligned or bent pulley. Defective idler pulley. Incorrect belt being installed. The belt must be an exact match, or it will self destruct.
you just use the gears and conveyor belts
I'm not sure what ya got but I've had bad "idler" pulleys dry up and start taking out my belts before. Either start to get misaligned or just freeze up.
When we changed the belts on our '94 Grand Voyager the belts made the most awful sqealing noise. We "lubricated the belts with a drop of dawn dish soap and the sqealing went away. You can also try belt dressing. If that doesn't work... the people at Auto Zone are very helpful in explaining how to change the bearings youself.
You don't. Buy new or good used seat belts. Don't try to fix them if they are not working.
i don't know off the top of my head but I know the Chilton manual (could be at your library) is really detailed on how to fix it.
