V-Belt, Kinney, Rotary Piston, KTC55, KTC60, Part# 051155

The V-belt is the simple rubber belt that connects your motor to the pump. It wraps around two pulleys. One pulley is on the motor. The other is on the pump shaft.

When the motor spins, the belt spins the pump. Without a good belt, your pump cannot run properly.

The job of the V-belt is simple but very important. It transfers power from the motor to the pump. The pump needs this power to spin its internal parts and create vacuum .

Here is how it works:

• The motor spins its pulley

• The V-belt grips the motor pulley

• The belt turns the pump pulley

• The pump shaft spins

• The pump creates vacuum

If the belt is worn or loose, it slips. The pump does not spin as fast as it should. Your vacuum pressure drops.
