Simplicity 1003 - Clutch Adjustment; Pulley Alignment

fSimalidiu
Adjustments
When a clutch lever is squeezed to engage the
clutch, an idler pulley (items A and B, figure 18)
moves against and tightens the related belt. Power
should then be transferred from the engine pulley
to the driven pulley without belt slippage. If a
clutch is not disengaging properly or if belt slippage
occurs, adjust the clutch as follows:
1. Loosen setscrew (item C, figure 18).
2. Slide wire clamp (item D) up clutch rod (item
E) to increase belt tension or down rod to de¬
crease belt tension.
3. Retighten setscrew.
4. Check, and, if necessary, repeat adjustment
until clutch operation is satisfactory.
BELT TENSION
Normally, belt tension can be adjusted by increas¬
ing clutch tension (moving wire clamp further up
control rod). After some use, however, belts may
stretch so that this adjustment cannot be made. If
this occurs, loosen the four engine mounting nuts
(see figure 19). Slide out one or two of the slotted
shims which are stored under the mounting nuts,
and insert the shims between the engine and frame
as shown in figure 19. Retighten engine mounting
nuts and readjust the clutch as necessary.
For model 1003 tillers, the engine drive pulley is
properly aligned when it is 0.688 inch, or 11/16
inch (17.4 mm), from the end of engine shaft (see
figure 20). If not, loosen engine pulley setscrew and
adjust as required. Be sure to retighten setscrew.
Then visually check the alignment of all three pul¬
leys. If the worm gear drive pulley is not aligned
with the engine pulley, loosen the setscrew and
move pulley as required. Retighten setscrew.
