MAINTENANCE (cont.)
Tensioning V-belt(s) fig. 14 & 15
Proper belt tension is critical to good performance. The normal deflection on each
side should be 9mm (3/8”) to 13mm (1/2”) with moderate pressure from your
thumb or finger.
Proper adjustment will assure long belt life.
Too much or too little belt tension will cause
premature belt failure.
1.
Loosen the lock nuts B, leaving enough
space between the nut and bracket.
2.
Loosen 4 engine mount bolts (do not
remove) only enough to move the engine
forward.
Note:
Two of the engine mount bolts are
not shown in fig. 15. They are located on the
opposing side of the engine deck.
3.
Push engine toward the back of the plate by
turning the adjustment bolts A to remove
any slack in V-belt(s).
4.
Tighten the engine mount bolts.
5.
When the V-belt tension is correct, tighten the lock nuts B against the bracket.
6.
Replace the belt guard.
Note:
If the adjustment bolts run out of adjustment, the belt(s) may have to be
replaced.
