Pulley and Idler Shafts

Transport systems on the machine contain pulleys and a belt to transport the door in and out of the 
machine. Each pulley contains an idler shaft that has a zerk fitting to apply grease. An opening in 
the idler shaft dispenses grease to the inner diameter of the pulley.

Pulley in Action

Breakout of Pulley Assembly

Grease IN

Grease Out

Note: 

It is important not to overfill 

the Idler Shaft. Avoid getting 
excess grease on the belts
