Bosch Fuel Injection Pump (EPVE)
Illustration 1 g00896561Note: Parts that are inside of the fuel injection pump are only serviceable by an authorized Bosch dealer. Please consult your parts book for availability of parts on the outside of the pump that are not related to the settings of the fuel pump and for the possibility of remanufacturing options.Hub nut (not shown)Note: Do not release the hub nut from the fuel injection pump. The fuel pump hub is positioned to the pump shaft in order to ensure that the fuel pump is in the correct position for timing. If the hub is removed, the hub will need to be accurately positioned to the pump shaft. Accurate positioning requires the use of special equipment by a Caterpillar Dealer. (1) Tighten the screw for the low idle speed adjustment to the following torque. ... 4 to 4.5 N m (35 to 40 lb in) (2) Tighten the fitting for the fuel return line connection to the following torque. ... 5 to 6 N m (44 to 53 lb in) (3) Tighten the fitting for the fuel supply connection to the following torque. ... 22 N m (16 lb ft) (4) Boost control (if equipped) (5) Tighten the high idle speed adjustment screw to the following torque. ... 4 to 4.5 N m (35 to 40 lb in) (6) Tighten the nuts for the high pressure fuel line connection to the following torque. ... 22 N m (16 lb ft) (7) Tighten the flange nuts to the following torque. ... 22 N m (16 lb ft) (8) Tighten the fittings for the fuel discharge lines to the following torque. ... 70.5 to 81.4 N m (52 to 60 lb ft)
Illustration 2 g00766439 (9) Locking spacer (If equipped) Note: The drive shaft of the fuel injection pump must not be turned without the spacer in position under the locking screw (10). (10) Tighten the locking screw to the following torque. ... 27 N m (20 lb ft) (11) Tighten the nut for the drive gear to the following torque. ... 80 N m (59 lb ft)
Illustration 3 g00639086Note: Before the crankshaft is turned or the fuel injection pump is installed, move the locking spacer (9) under the locking screw (10). Refer to position (A) that is in Illustration 3. This position ensures that the pump drive shaft is released.Timing Information for the Bosch Fuel Injection Pump

(1) The engine must be set at the TC position on the compression stroke for the number 1 piston. The fuel injection pump mark angle and the displacement of the piston can be checked when the plunger for the fuel injection pump is set at 1.00 mm (0.039 inch).
(2) The information plate on the fuel injection pump is stamped "J609".
(3) "AD70229" and "AD702230" only
(4) "AD80643" only
(5) The cold start advance (KSB) must be energized before the timing is set.Note: Later Bosch Fuel Injection Pumps use a pin to time the pump.Stanadyne Fuel Injection Pump (DB2 or DB4)
