Sharp SX 1075

PRESSURE BAR GEARBOX
1. Remove the rear motor cover (Figure 3-288
and 3-289).
2. Locate the pressure bar gearbox and motor.
Examine the base plate underneath the
assembly (see Figure 3-285). The plate should
be clean and dry. If oil is present, the gearbox
is leaking and needs repair or replacement.
3. Remove the outside frame guard (Figure 3-
290).
4. Spin the output shaft and pulley on the gearbox
by hand (Figure 3-291). If the shaft is able to
be turned, it is functioning properly. Note: the
pulley on the gearbox will be difficult to turn
with the belt for the pressure bar still attached,
but will move with an adequate amount of
force.
