6 ADJUSTMENTS
6.4 TRACTION DRIVE IDLER CABLE _____________________________________________
1. Engage OPC handle. [ See Section 4.1]
2. Adjust cable nuts (E) as necessary to obtain 0.18
inch (3.3 mm) deflection with a 4.4 lb (2.0 kg) push
for new belt or 3.0 lb (1.4 kg) push for used belt at
location shown.
3. Addition adjustment available at handle end of cable
or by moving cable bracket.
4. Test handle operation. When OPC handle is
engaged, parking brake (F) should release and idler
pulley should engage traction drive.
6.5 AERATOR TIMING _________________________________________________________
Note: Improper timing between the aerator crankshaft
and the camshaft will cause elongated holes while
aerating and excessive noise in the camcase.
1. Remove shields from both sides of unit.
2. Remove aerator chain connecting crankshaft to
camshaft from both sides of unit.
3. Loosen stud between crankshaft halves.
4. Rotate right camshaft sprocket (G) until the keyway
is pointing towards the front of the unit. Timing
marks should be at a 45° angle with dot towards the
lower front. [See Figure 6D]
5. Rotate right side crankshaft sprocket (H) until the
timing marks are horizontal with the dot towards the
front. Keyway should be at a 45° angle.
6. Install right side aerator chain (J). Crankshaft
sprocket may be rotated up to 5° in a clockwise
direction only to properly mesh with the chain.
7. Rotate left crankshaft sprocket (K) until the timing
marks are vertical and dot is towards the ground.
[See Figure 6E]
8. Install left side aerator chain (L). Crankshaft
sprocket may be rotated up to 5° in a counter-
clockwise direction only to properly mesh with the
chain.
9. Tighten stud between crankshaft halves.
10. Install shields. Do not operate aerator without all
shields properly installed.
