Belt Replacement (All SPS
Series Models)
Normal wear may necessitate belt tensioning or
replacement. Time of replacement will vary according to
usage and belt load factors.
Replacement is easy and requires a few hand tools.
1. Two 9/16” wrenches.
2. 3/4” wrench.
3. 3/8” open-end wrench.
4. Carpenters square or straight edge.
5. Spray lubricant.
6. Spark plug wrench.
1. Make sure the Drum Access Panel is installed. This
ensures the drive ends are in the proper position for
servicing.
2. Clean the machine exteriors so you can locate all
the appropriate parts.
3. Using a 3/4” wrench, remove the two acorn nuts
attaching the belt cover to the side of the machine.
Remove the cover and set it aside.
4. Lubricate the motor plate (belt tensioning) jackscrew
with spray lubricant on the front of the machine.
5. Use a 9/16” wrench to loosen the jackscrew
retaining nut.
6. Using the 3/8” open-end wrench, begin to screw the
motor plate jackscrew back into the long hex nut
below it. Screw it all the way until resistance is felt.
7. Loosen (do not remove) the four bolts (2 per side)
that secure the motor mount plate to the main
machine frame.
8. Loosen the four bolts attaching the motor to the
motor plate. After sufficiently loosening all four, slide
the motor back all the way to the rear. This will
loosen the belt sufficiently to remove it.
9. Either cut or roll off the belt from the pulleys. If you
roll it off, move it over one groove at a time on the
upper and lower pulleys to completely remove it.
10. Roll the new belt on one groove at a time on both
the top and bottom pulleys.
To avoid injury from unexpected start up, disconnect
spark plug wire before you service your unit.
