Safety Information
Read through the safety information and operating instructions before using your Waterous Reversing
Transmission.
WARNING
!
Death or serious personal injury might occur if proper
operating procedures are not followed. The operator,
as well as other individuals using the apparatus must
be familiar with these operating instructions as well as
other operating instructions and manuals for the appa-
ratus, water hydraulics and component limitation.
WARNING
!
Unexpected Truck Movement
May result in serious personal injury or death
Failure to properly shift transmission in accordance to
the transmission operating instructions may result in
unexpected truck movement which may result in
serious personal injury or death.
WARNING
!
If the truck attempts to move, reduce engine speed to
idle. Put truck transmission in NEUTRAL and repeat
shifting instructions.
NOTICE:
When towing, disconnect the drive shaft that connects
the pump transmission’s rear output (coupling) shaft
to the vehicles differential. Failure to do so may result
in damage from lack of lubrication.

Introduction
This publication contains operation and maintenance instructions for the Waterous Model TMR Reversing Transmission. Re
fer to Service Parts List SPL81121 for reference numbers when ordering repair parts. Also provide the serial number of the
TMR when placing inquiries or orders.
General Descri
p
tion
The TMR Reversing Transmission is designed for installa
tion in a vehicle between the main transmission and rear
axle to provide reverse vehicle motion with the main trans
mission in forward gears. In forward, power is transmitted
directly through the TMR transmission to the rear axle input
and output shafts rotating in the same direction. When in re
verse, power is transmitted through a chain drive to a coun
tershaft and then through gearing to the output shaft. The
output shaft rotates opposite the input. When the TMR trans
mission is operated in either mode, it allows the vehicle's
main transmission to be operated in any desired gear.
The chain drive is a Morse Hy-Vo®and the gears helical
type. Ball bearings are used throughout. The input and out
put shaft are available with either 1-3/4-10 SAE spline or
2-10 SAE spline.
Shifting from forward to reverse mode is through an external
lever. The design of the internal shift mechanisms is self -
locking after the shift has been completed.

Instructions
Vehicles with Manual Transmissions Vehicles With Automatic Transmissions
The following procedure is used for shifting the TMR
Transmission into forward or reverse.
1. Bring vehicle to a complete stop.
2. Shift main vehicle transmission into neutral.
If the shift cannot be completed due to a butt tooth condi
tion of the shift collar inside the TMR Transmission, do not
force the shift but proceed as follows:
a. With engine at low or idle speed, depress clutch
and shift vehicle main transmission into forward
gear, slowly let out the clutch to rotate propeller
shaft. This rotation will reposition the shift collar
for movement into either forward or reverse
mode.
b. After shift has been completed, depress clutch
and operate vehicle in usual manner.
1. With engine at idle speed, place automatic transmis
sion in NEUTRAL.
2. Shift TMR Transmission to desired mode.
3. If the shift cannot be completed due to a butt tooth
condition, shift automatic transmission momentarily
to REVERSE while keeping pressure on the TMR shift
lever to complete the shift.
4. Shift automatic transmission to desired gear or drive
range.

Maintenance
Lubrication
IL3598
1. Fill transmission to bottom of oil plug with automatic transmission fluid. For ambient temperatures over 90_F, SAE
20 oil 300 SSU @ 100_F with service classification SA, SB or SC should be used. Transmission holds approxim
ately 5 quarts.
2. Change fluid every 6 months or 100 hours of operation.

Towing
When towing, disconnect the drive shaft that connects the pump transmission’s rear
output (coupling) shaft to the vehicles differential. Failure to do so may result in
damage from lack of lubrication.
Shift Linkage
Periodically check all shift linkage for freedom of movement and clean as necessary.
