Belt Replacement And Alignment - Smith SPS8 User Manual & Parts List

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 a straightedge
5. WD40
6. Spark plug wrench
Before beginning servicing on any gasoline-powered unit,
DISCONNECT SPARK PLUG WIRE!
BELT REPLACEMENT:
1. Make sure the removable side cover is
installed or if working on an SPS8, the
drum drive shaft is installed and tightened
securely. This insures the drive ends are
in the proper position for servicing.
2. Remove the spark plug.
3. Clean the machine exterior so you
can locate all the appropriate parts.
4. 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.
5. Lubricate the motor plate (belt tensioning)
jackscrew with WD40 on the front left
of the machine.
6. Use a 9/16" wrench to loosen the jackscrew
jam nut.
7. 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.
8. Loosen (do not remove) the four bolts
(2 per side) that secure the motor mount
plate to the main machine frame.
9. 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.
10. 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.
