All Engines With Sleeve Metering Fuel Systems The 3P2200 Calibration Tool Group, some tools from the 5P4203 Tool Group (field service) and some new tools, are needed to do the calibration procedure for the Sleeve Metering Fuel Pumps. Make reference to Page 4 of this instruction for the list of all tools that are needed.Fuel pump calibration or crossover lever adjustment, can be checked and adjustments made with the fuel pump housing either on or off the engine, but the steps that follow (A, B and C) must always be done before any procedure is started.A Disconnect the battery and shutoff the fuel supply to the fuel pump housing.B Thoroughly clean the outside of the fuel pump housing, and the area around the fuel pump housing.C Remove the fuel shut-off solenoid, the cover for the torque control group and the large cover on the fuel pump housing. Remove fuel from the inside of the fuel pump housing before removal of the side cover on 4 or 6 cylinder fuel systems; or after removal of the top cover on V8 fuel systems.Tools Needed For Calibration Procedure
3P2200 Tool Group
Needed Parts From 5P4203 Tool Group For earlier 3P2200 Calibration Tool Groups, remove the 1P7377 Spring and install the new 5P6557 Spring (5) on 3P1540 Pump Assembly (4) as shown.
Check The Calibration Of The Fuel Pumps - 4 Or 6 Cylinder Engine
(1) Remove the air-fuel ratio control, if so equipped. (2) Install 3P1545 Pin (1) 17.3734 (0.6840") in hole (A). The pin length is given on the large diameter of the pin. Use 8S2243 Wrench to remove the fuel pumps that are to have the calibration check. Install 5P6602 Adapter (2) with 1D4538 Bolt and 1D4533 Bolt. Install 8S7271 Screw (3) in adapter (2). Use 2P8264 Socket with a torque wrench to tighten screw (3) to a torque of 2.3-2.8 N m (20-25 lb. in.), to push pin (1) against the pump housing.(3) Turn the governor control to full load and fasten it to this position. (4) Check the spring (4) that is on the 3P1540 Calibration Pump (5). Calibration pump (5) must have the 5P6557 Spring (4). Earlier 3P1540 Calibration Pumps had a 1P7377 Spring. For those earlier calibration pumps, remove the 1P7377 Spring and install the 5P6557 Spring (4). See page 5 of this instruction. (5) Clean the top of the pump, seat area and groove (8) of calibration pump (5). Put clean diesel fuel on the plunger for lubrication. Put pump (5) in a fuel pump bore so flat (B) is toward tang (6) on lever (7). When pump (5) is all the way in the fuel pump bore, turn pump (5) approximately 180°, in either direction, so tang (6) fits in groove (8). Install the 4N218 Bushing. Use the 8S2243 Wrench, with a torque wrench, and tighten the bushing to a torque of 80 7 N m (60 5 lb. ft.). (6) Assemble collet assembly (9) to 3P1568 Indicator (10) and tighten nut (C) on
