005-037 Fuel Pump Timing - JustAnswer
Fuel Pump TimingPage 1 of 12View Related Topic005-037 Fuel Pump TimingGeneral InformationPump-to-engine timing is extremelycritical. Pump timing that is off by only afew crankshaft degrees will cause:1. Poor performance - starting andpower.2. Excessive smoke.3. Poor fuel economy.TimeEngine pump timing begins with thetiming of the fuel injection pump drivegear to the camshaft gear.The first step is the location of TDC of thecompression stroke for cylinder Number1.Then, depending on the engineconfiguration, an alpha character on theinjection pump drive gear will possiblyneed to be aligned with the mark on thecamshaft l/en/procedures/40/40-005-037-tr.html11/4/2010
Fuel Pump TimingPage 2 of 12This table must be used to maintain proper fuel injection pump-to-engine timing. TheControl Parts List (CPL) number from the engine dataplate and the Control Parts ListManual, Bulletin 3379133 or 4021327, must be used to determine whether the engineis certified, and if so, what year and regulating agency (EPA or CARB).Given this information, use the following table to determine which letter on the fuelinjection pump drive gear is aligned with the camshaft gear.NOTE: Timing mark alignment is not required for the Nippondenso EP-9 orBosch in-line drive gear.NOTE: The timing mark is not required for Bosch VE and DP210 used on Tier IIIndustrial engines.

Fuel Pump TimingPage 3 of 12To verify that the fuel injection pump istimed correctly, first check the alignmentmarks on the pump flange and gearhousing.NOTE: 1 mm of rotation past thetiming mark will advance or retard(depending on direction of rotation)the pump timing by 1 degree.The Lucas CAV DPA, DPS, DelphiDP210, Stanadyne DB4, and the Bosch VE fuel injection pumps all have aprovision for locking the pump shaft at aposition corresponding to top dead centerfor cylinder Number 1. New andreconditioned fuel injection pumps mustbe received with the shafts located in thisposition.At the point of injection, the keyway ofthe shaft will align with the delivery valvereceiving the injection and the illustratedhash mark on the seal housing.NOTE: The illustrated mark is forreference only and must not be usedfor setting the fuel injection pumptiming.The Number 1 cylinder delivery valve ismarked as illustrated.Four cylinder ASix cylinder /procedures/40/40-005-037-tr.html11/4/2010

Fuel Pump TimingPage 5 of 12The flange of a replacement pump mustbe marked to align with the mark on thegear housing after installation.During production, after the locked pumpis fitted to the engine with cylinderNumber 1 at top dead center (TDC), amark is stamped on the gear housing andthe pump flange. Thereafter, when thesemarks are aligned, the pump is correctlytimed to the engine.NOTE: The marks on the gear housingand the pump flange are unique toeach engine.See Service Tool Instruction, Bulletin3400196 and Service Tool Catalog,Bulletin 3377710 to determine theappropriate Bosch timing tool andadapter kit part numbers.A special indicator can be used tomeasure the position of the Bosch VEfuel injection pump plunger to checkpump timing.Stanadyne DB4 Fuel Injection PumpTimingClean all debris from around the fuelinjection pump timing window ml/en/procedures/40/40-005-037-tr.html11/4/2010

The fuel pump should be mounted below the fuel tank or at least the bottom 25% of the fuel tank for the pump to work properly. If necessary put a cover over it to keep the environment away form the pump. A fuel filter is to be installed in the fuel line PRIOR to the fuel pump. Premature failure of the pump can be the result of improper fuel .
