Install The Belt; Tighten The Belt - Craftsman CMXEOCG322 Owner's Manual

ASSEMBLY STEP 4

INSTALL THE BELT

1. Pull the belt around the idler pulley and toward the trolley. The
ribbed side must contact the pulley.
2. Hook the trolley connector into the retaining slot on the trolley
as shown (Figure 1).
3. With the trolley against the screwdriver, dispense the
remainder of the belt along the rail length toward the motor
unit and around the sprocket (Figure 2). The sprocket teeth
must engage the belt.
4. Check to make sure the belt is not twisted. Connect the trolley
threaded shaft with the master link (Figure 3).
• Push pins of master link bar through holes in end of belt
and trolley threaded shaft.
• Push master link cap over pins and past pin notches.
• Slide clip-on spring over cap and onto pin notches until
both pins are securely locked in place.
5. Remove the spring trolley nut from the threaded shaft.
6. Insert the trolley threaded shaft through the hole in the trolley.

ASSEMBLY STEP 5

TIGHTEN THE BELT

1. By hand, thread the spring trolley nut on the threaded shaft
until it is finger tight against the trolley. Do not use any tools.
Remove the screwdriver.
2. Insert a flathead screwdriver tip into one of the nut ring slots
and brace it firmly against the trolley.
3. Tighten the spring trolley nut with an adjustable wrench or a
7/16" open end wrench about a quarter turn until the spring
releases and snaps the nut ring against the trolley. This sets
the spring to optimum belt tension.
