Single Stage Belts Original Message Jan 25, 2011 10:02 pm
The belt in my Craftsman single stage unraveled so I had to replace it. During inspection, I noticed that the rear portion of the motor mount had cracked and the engine/crank shaft had a fair amount of movement to it which, in combination with higher power being put out likely caused the belt to come apart. I repaired the motor mount and everything is good and solid again.
The machine takes a 3/8 x 35" belt. I called Sears and they wanted .... wait for it..... $38.95 plus $7.00 shipping for a belt they claim is 3/8 x 34-3/4" part no. 760928 - 2150. I suspect the belt on the machine was original equipment. It had the same part no. 760928 - 2150 printed on it. I went to NAPA and found an FHP belt for garden equipment coded as a 3L350 which is 3/8 x 35" and fits the machine perfectly. The NAPA belt was only $6.00.

Well, there you go!
A free mini-history lesson. That was informative and interesting Bill.
Impressive power can be had just by the addition of a piece of string. I don't understand why manufacturers limit the engine speed so much on these two cycle machines. My two stroke Toro Power Shovel runs at 7 to 8 thousand rpm. This Tecumseh doesn't seem to mind running at 5000 to 6000 rpm. I don't recommend revving the engine unnecessarily with no load on it. I run it at normal speed until I get it into the snow then open up the governor. That way, the engine is working but not screaming.
