Installing 20 Liter (5 Gallon) Pump Module
Before starting procedure, make sure:
D system documentation and copies of the following
manuals are available:
D
310525 (20 l/5 gal.) ram
D
310528 (20 l/5 gal.) supply unit
D
308570 (servicing pump)
D air motor is secured in the ram (if procedure in
310528 was used), or 2 people are available to hold
pump assembly
Connect pump module to air motor as follows:
1. Make sure coupling nut (40) and coupling collars
(30) are in place on displacement rod.
Collar couplings should be placed in coupling nut
so large flanges point upwards.
2. Attach pump module to air motor. Orient pump's
fluid outlet (60) to motor's air inlet (70).
3. Remove or loosen back shroud. This gives access
to back stand-off rod (90).
NOTE: RTV sealant on the pump shroud may
make it difficult to remove individual shroud pieces.
Use a knife or razor to scrape the sealant off of the
seams of the shrouds.
4. Screw nuts (10) onto 3 stand-off rods (20 and 90),
and torque to 81 – 89 N.m (60 – 66 ft-lb).
5. Screw coupling nut (40) onto motor shaft loosely.
Hold motor shaft flats with wrench to keep it from
turning. Use adjustable torque wrench to tighten
coupling nut. Torque to 196 – 210 N.m (145 –
155 ft-lb).
6. Check torque setting on packing nut/wet-cup (50).
Ensure it is 203 – 237 N.m (150 – 175 ft-lb).
Installation
7. Attach follower to pump:
a. Attach pump inlet (80) to follower plate.
b. Attach air line to blow-off valve.
c. Attach and secure coupling nuts to follower
d. Connect follower-plate wires to junction box.
e. Insert follower-plate sensor into follower plate.
