Fuel injection pump - Remove (B.20.A.21 - F.10.A.10)
CX720, CX740, CX760, CX780, CX820, CX840
IMPORTANT: Internal repairs to the fuel injection pump must be accomplished through a Bosch authorized Diesel
Service Dealer (DSD). The only adjustment that can be accomplished to the pump on-vehicle is low speed idle ad-
justment.
Before removing any fuel lines, clean the exterior of the fuel injection pump with clean fuel oil or solvent to help prevent
the entry of dirt or other contamination. The area can be steam cleaned (which is probably the best method of getting
the area clean), but it can only be done when the engine is cold and shut off.
IMPORTANT: Do not wash or steam clean the engine while it is running or still hot from running. Serious damage to
the injection pump could occur.
1. Removal
Disconnect the negative battery cables from the bat-
tery and/or batteries.
Perform the injection pump timing check Fuel injec-
tion pump - Timing check (B.20.A.21 - F.40.B.12)
and install the injection pump timing pin 295005 (NA-
FNH00536-1).
2. Remove pump drive gear retaining bolts (1) retaining
plate (2) and gear (3).
3. Disconnect all pipework and fuel lines. Cap all open-
ings to prevent dirt contamination.
On electronically controlled injection pumps discon-
nect the harness connection to the electronic actua-
tor.
Use two wrenches on these high pressure lines to pre-
vent distorting or rotating the pumping element. Z030
