drive belt slipping

Recommended Posts


Bombing up a hill in 3rd gear on my Simp 4108, pulling an empty cart, I slowed to a near stop. Looking down expecting to find one tire spinning (a common problem) that was not the case. The belt was slipping. The belt is old but in apparent good shape. The tension seems fine if not overly tight. There appeared no way to adjust the tension. Is there an adjustment or do I need a new belt? Thanx, Dave

If the belt is stretched, then you have to go through that wondrous brake, and clutch adjustment procedure. On the 4200s there is an idler puller that is held tightly against the drive belt. Most of the tension is provided by the clutch rod, and its spring. The adjustment procedure is part of the section on drive belt replacement paragraphs, of the owners manual. Page 34 in the PDF viewer, or page 32 on the visual.

If you do not have the OPS and/or IPL manuals. I can email them to you, send me a PM w/ your email address.


I'm guessing your tractor part# is 1690261.

The set collar did the trick. Took off the belt, loosened the 1/4" set bolt, moved the collar a little tighter onto the spring, and that did it.dOd Thanx, Dave

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
