Pilot ports in the cylinder control the pilot valves as the
ports are uncovered by the piston.
NOTE: These air motors are not available to be
purchased separately. However, a kit can be pur-
chased that includes the entire motor. See Figure 3.
Description and Operation
"RAM" air motor model 339413 series power a
variety of fluid and material reciprocating pumps.
The pump tube assembly is secured to the motor
with the nuts and bolts equipped with the motor. This
hardware utilizes keepers (part of the pump) that hold
the body of the pump tube to the motor. See Figure 3.
Models 339413 and 339413-A1
The difference between these models is the standard
of thread for the air inlet. Refer to Figure 1.
Installation Operation
IMPORTANT: A moisture separator/fil-
ter should be used to prevent contamina-
tion and the washout of lubricant.
The motor is packed with Teflon lubricant and
requires no additional lubrication except during service.
Lubricator
Alemite, LLC recommends to operate the motor
without an air line lubricator.
CAUTION
Should an air line lubricator be installed, never
allow the motor to operate without lubrication
(minimum 10W oil) or the warranty will be void.
Motor Operation
WARNING
Read the label on the motor prior to
operation. Personal injury can occur.
Pneumatically actuated pilot valves (one set at each
end of a directional spool) cause the directional spool to
shift. The directional spool directs air pressure to one
side of the motor’s piston and allows air to exhaust
from the opposite side.

IMPORTANT: Prior to performing any
maintenance procedure, the following
safety precautions must be observed. Per-
sonal injury may occur.
WARNING
Do not use halogenated hydrocarbon
solvents such as methylene chloride or 1,1,1
trichloroethane in this motor. An explosion can
result within an enclosed device capable of con-
taining pressure when aluminum and/or zinc-
plated parts come in contact with halogenated
hydrocarbon solvents.
Release all pressure within the system prior to
performing any overhaul procedure.
• Disconnect the air supply line from the
motor.
• Into an appropriate container, operate the
control valve to discharge remaining pres-
sure within the system.
Never point a control valve at any portion of your
body or another person. Accidental discharge of
pressure and/or material can result in personal
injury.
Read each step of the instructions carefully.
Make sure a proper understanding is achieved
before proceeding.
