4.9 EMERGENCY PUMP SHIFT PROCEDURES
Before implementing manual override shift procedures, repeat the recommended shift
procedures. If the shift fails, proceed as follows:
1. Bring the truck to a complete stop.
2. Apply the truck parking brake, and chock the wheels.
3. Shift the truck transmission to the NEUTRAL.
4. For PUMP or ROAD position, place the in-cab shift control in the NEUTRAL (N)
position.
5. Shut down the engine.
WARNING!
DO NOT ATTEMPT EMERGENCY SHIFT PROCEDURES WHILE THE ENGINE IS RUN-
NING.
6. Employ manual override procedure at the shift cylinder on the pump gearbox as
follows:
 An eyebolt is provided in the shift shaft to accept a drift punch or screwdriver.
 Insert the tool into the hole provided, then pull or push the shaft manually.
 Pull the shaft OUT for PUMP position (after in-cab control valve selection), or
push shaft IN for ROAD position (after in-cab control valve selection).
 If the shift stroke cannot be completed manually, turn the driveshaft slightly by
hand to realign the internal gears and repeat the manual shift.
Note: Certain apparatus may offer a manual shift override handle or separate cable for acti-
vation.
7. Once gearbox shift is complete, make sure all personnel are clear of the under-
side of that apparatus and start the engine to proceed with the desired operation.
