Bosch Inline Pump Removal and Installation
John Deere Applications (pin timed)
Removal
1. Clean injection lines and area around the injection pump with cleaning
solvent or a steam cleaner.
2. Rotate engine flywheel (in normal running direction) until No.1 piston is at
“TDC" (top dead center) compression stroke. At this point, John Deere
JOE81-4 timing pin should enter hole in flywheel.
IMPORTANT: Never steam clean or pour cold water on an Injection pump while
the pump is running or while it is warm. To do so may cause damage to the
injection pump.
3. Remove injection pump drive gear cover and O-ring.
4. Install JDG886 Injection Pump Timing Pin (A) through injection pump drive
gear into injection pump hub until it bottoms. In some instances, it may be
necessary to rotate the pump drive hub slightly to get the pin installed.
