Loosening and Rotating Bypass Hex on Multi-
Function Valve
8.1.3 Engaging the Bypass Function
The bypass function (see Sec. 2.4.6 for description)
is performed by the multi-function valve cartridges.
The prime mover should be shut down when opening
or closing the bypass valves.
The bypass valves on both of the multi-function
valves must be opened to engaged the bypass func-
tion.
1. Using a 1-1/16 inch (030 through 100) or 1-3/8
inch (130 through 250) wrench on the middle
sized hex of the multi-function valve cartridge, and
a 1-1/4 inch (030 through 100) or 1-5/8 inch (130
through 250) wrench on the large hex to prevent
rotation of the cartridge assembly, rotate the middle
hex three revolutions counterclockwise to open
the bypass valve. Do not rotate more than 3-1/2
revolutions, as additional rotation will permit ex-
ternal leakage.
2. For units with an MDC-type control, prior to mov-
ing the vehicle or otherwise causing the motor
shaft to turn, move the control handle of the
manual displacement control on the pump to the
maximum full forward position. Hold the handle in
this position during bypass valve operation.
WARNING
“Tow” at extremely low speeds and for short
distances only.
3. To close the bypass valve, rotate the middle hex
clockwise until it is seated. Then torque the middle
hex to 41 Nm (30 lbf•ft).
