T−328 Page 3 of 4IntroductionThis publication contains operation and maintenance instructions for the Waterous Model TMR Reversing Transmission. Refer to Service Parts List SPL81121 for reference numbers when ordering repair parts. Also provide the serial number of theTMR when placing inquiries or orders.General DescriptionThe TMR Reversing Transmission is designed for installation in a vehicle between the main transmission and rearaxle to provide reverse vehicle motion with the main transmission in forward gears. In forward, power is transmitteddirectly through the TMR transmission to the rear axle inputand output shafts rotating in the same direction. When in reverse, power is transmitted through a chain drive to a countershaft and then through gearing to the output shaft. Theoutput shaft rotates opposite the input. When the TMR transmission is operated in either mode, it allows the vehicle'smain transmission to be operated in any desired gear.The chain drive is a Morse Hy-Vo® and the gears helicaltype. Ball bearings are used throughout. The input and output shaft are available with either 1-3/4-10 SAE spline or2-10 SAE spline.Shifting from forward to reverse mode is through an externallever. The design of the internal shift mechanisms is self -locking after the shift has been completed.Shifting InstructionsVehicles with Manual Transmissions Vehicles With Automatic TransmissionsThe following procedure is used for shifting the TMRTransmission 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 condition of the shift collar inside the TMR Transmission, do notforce the shift but proceed as follows:a. With engine at low or idle speed, depress clutchand shift vehicle main transmission into forwardgear, slowly let out the clutch to rotate propellershaft. This rotation will reposition the shift collarfor movement into either forward or reversemode.b. After shift has been completed, depress clutchand operate vehicle in usual manner.1. With engine at idle speed, place automatic transmission in NEUTRAL.2. Shift TMR Transmission to desired mode.3. If the shift cannot be completed due to a butt toothcondition, shift automatic transmission momentarilyto REVERSE while keeping pressure on the TMR shiftlever to complete the shift.4. Shift automatic transmission to desired gear or driverange. |
