An in-line filter or dryer, available from your local
Quincy distributor, may be re quired to eliminate
the moisture.
Condensation in the air tank can be kept to a
mini mum by draining the tank on a daily basis.
This also reduces the risk of rust developing and
weak ening the tank.
Belt Alignment & Adjustment
Drive belts tend to stretch with normal use and
require adjustment periodically (check monthly). In
order to adjust the drive belt the belt guard must
be removed. Prior to re moving the belt guard, follow
the procedures outlined under MAINTENANCE.
Check the belt alignment by placing a straightedge
against the face of the flywheel, touching its rim at
two places (refer to Fig. 6). Adjust the flywheel or
motor pul ley so that the belt runs parallel to the
straightedge. Use a wheel puller to move the motor
pulley on the shaft.
Fig. 7 Typical Belt Adjustment
Fig. 6 Typical Belt Alignment
Properly adjusted, a 3 pound pressure applied to
the belt between the motor pulley and the compressor
flywheel will deflect the belt about 1/4”(6mm.). Refer
to Fig. 7. To ad just the belt tension, loosen the 4 motor
mounting screws and slide the motor in the proper
direction. Retighten the motor mounting screws.
