ADJUSTING THE BELTS


A loose belt reduces pump output due to slippage, and results in excessive wear. Once every six
months, check for proper V-belt tension. V-belt tension is proper when the back side of the belt
can be depressed approximately 3/8" (9.5mm). If adjustment is required, loosen cap screws and
pivot idler arm either upward or downward to obtain proper tension. Cap screws must be re-
tightened before belt tension can be checked.
