5.
If the air motor does not require servicing, leave it
attached to its mounting. However, if the air motor
does need to be removed, refer to the Supply Units
Repair-Parts manual 312373 for instructions.
6.
Pumps with 100cc, 200cc, and 250cc displacement
pumps only: Remove clip (9), and slide coupling
cover (8) up to remove coupling (7).
7.
Pumps with 500cc displacement pumps only: Use a
hammer and brass rod to loosen coupling nut (8).
When coupling nut drops down remove coupling
collars (7) and coupling nut from displacement rod.
8.
Use a wrench to hold the tie rod flats to keep the
rods from turning. Unscrew the nuts (5) from the tie
rods (3) and carefully remove the displacement
pump (2).
9.
Refer to the Check-Mate Displacement Pump man-
ual 312375 to service the displacement pump. To
service the air or hydraulic motor, refer to the sepa-
rate motor manual, supplied.
CAUTION
Be sure to use at least two people when lifting, mov-
ing, or disconnecting the pump. This pump is too
heavy for one person. If you are disconnecting the dis-
placement pump from a motor that is still mounted (for
example, on a ram), be sure to support the displace-
ment pump while it is being disconnected, to prevent it
from falling and causing injury or property damage.
Do this by securely bracing the displacement pump,
or by having at least two people hold it while another
disconnects it.
