VANE CROSSING VANE
The Rineer patented vane crossing vane design produces
much higher volumetric and mechanical efficiencies than is
possible with a standard vane type design. This design
provides a sealing vane between cavities to improve
mechanical and volumetric efficiencies.
STARTING AND STALL TORQUE
The Rineer motor produces torque curves which are virtually
flat, with starting and stall torque equal to approximately 90-
94% of theoretical torque.
MORE POWER STROKES PER REVOLUTION
The 15 Series has four stator cavities and 10 rotor vanes.
Each rotor vane works in each stator cavity once per
revolution, which results in 40 power strokes per revolution.
This helps produce higher mechanical efficiency and flatter
torque curves.
BEARING LOADING
The bearings in the 15 Series can accept radial load per the
radial capacity chart. Thrust load is not recommended under
most conditions. Consult with a Rineer Application Engineer
for optional bearing configurations to match your application.
SEALS
Buna N seals are supplied as standard on the Rineer 15
series motors. Viton seals may be ordered as an option.
ROTATING GROUP - 1S or 1H
Under most operating conditions, 1S (standard rotating
group parts) should be used. Under some high speed
conditons 1H can be specified.
ROTATION
The 15 Series Motor rotates equally well in either direction
and smoothly throughout its entire pressure and speed
range. Looking into the end of the shaft, rotation is clockwise
when oil is supplied to port "A".
HORSEPOWER LIMITATION
Maximum horsepower limitations may vary with different
applications. When using the 15 Series Motor above 75
HP, consult a Rineer Application Engineer.
Technical Information - Retractable Shaft Motor

RETRACTING THE SHAFT

The shaft is spring loaded into the engaged position. Pulling
on the knob attached to the shaft at the rear of the motor will
move the shaft 1.25 inches into the motor.
CAUTION: Retracting the shaft must be done when the
motor and driven mechanism are not in operation and
are unloaded.
RETAINING SHAFT IN RETRACTED POSITION
The shaft is retained in the retracted position by inserting a
2.0 inch wide spacer between the rear housing and the knob
attached to the shaft. Depending on the application and
mounting position of the motor, the spacer design may vary.
Spacers are not supplied with the motor.

FILTRATION
25 micron minimum.
FLUID
We suggest premium grade fluids containing high quality rust,
oxidation and foam inhibitors, along with anti-wear additives.
For best performance, minimum viscosity should be
maintained at 100 SSU or higher. Fluid temperature should not

seal life while accelerating oxidation and fluid breakdown. Fire
resistant fluids may be used with certain limitations. Contact
Rineer for additional information.
CASE DRAIN
The 15 Series Motor is designed for either internal or external
case drain. Two case drain ports are supplied. When using
internal case drain, simply plug the two ports. When using
external case drain, use the port at the highest elevation. We
recommend case drain pressure of 35 PSI or less when using
the standard seals.
CASE DRAIN CIRCULATION
Fluid should be circulated through the case when a
temperature differential exists between the motor and the
O
system in excess of 50

MOUNTING
The mounting position is unrestricted. The shafts, pilots, and
mounting faces should be within .002 TIR.
INTERMITTENT CONDITIONS
Intermittent conditions are to be less than 10% of every minute.

RE-ENGAGING THE SHAFT

This is accomplished by releasing the shaft, then rotating it
clockwise until the splines of the shaft line up and engage the
splines of the driven mechanism.
CAUTION: Re-engaging the shaft must be done when the
motor and driven mechanism are not in operation and are
unloaded.
