FCG1 CONCRETE SAW — GUARDS, COVERS AND V-BELTS
Figure 8. V-Belt Tension Check
4. DO NOT over or under tighten the V-belt. Severe damage
can occur to the saw and engine crank shaft if the belt is
over-tensioned. A decrease of power to the blade and poor
performance will result if the belt is under-tensioned (loose
on pulleys).
NOTE
To Tighten the V-belt:
Figure 9. V-Belt Tension Adjust
1. With V-belt guard removed, loosen the 4 engine mounting
hex screws. (items 2 Figure 9)
2. Loosen locking nut on the V-belt tension adjuster, (3 ).
PAGE 18 — FCG1 CONCRETE SAW— OPERATION & PARTS MANUAL — REV. #1 (10/08/02)
V-belt alignment must be
rechecked after adjusting belt
tension.
3. Tighten the adjusting hex screw (4) while holding the engine
in place to maintain pulley alignment. (a screwdriver can be
used as a lever at the rear belt guard mounting boss to hold
the back of the engine while adjusting V-belt tension.)
4. Re-tighten the locking nut (3).
5. With V-belt held in proper alignment, (engine parallel with
the frame), re-tighten the 4 engine mounting hex screws.
Verify that all hex screws are properly tightened.
To Remove and Replace the V-belt:
If the V-belt become worn or damaged, replace it with P/N 15082
(Gates/Optibelt 3VX335).
1. Remove the 3 hex screws holding the V-belt guard and
remove the guard.
2. Loosen the 4 engine mounting hex screws. (item 2, Figure 9)
3. Loosen locking nut on the V-belt tension adjuster (item 3,
Figure 9). Loosen the tension on the V-belt by turning the
tension adjuster hex screw (item 4, Figure 9).
4. Pull the engine ahead to provide slack in the V-belt.
5. Loosen the 4 arbor shaft hex screws, (item 1, Figure 9).
Figure 10. V-Belt Removal
6. Remove the two outer arbor shaft hex screws allowing the
outside of the shaft to drop, (B in Figure 10), allowing removal
of the V-belt.
7. Reinstall new V-belt.
8. Re-install and tighten arbor shaft hex head screws.
9. With V-belt held in proper alignment, re-tighten the 4 engine
mounting hex screws. (Follow V-belt tightening procedures.)
10. Re-install belt guard with 3 hex screws.
