Caution: The fuel pump gear must be fitted to the engine before the crankshaft is rotated.
8 Carefully turn the gear counter-clockwise, by hand (C1), to remove the backlash between the idler gear and
the fuel pump gear. Do not rotate the crankshaft or the fuel pump shaft. Tighten the setscrews for the fuel pump
gear to 28 Nm (20 lbf ft) 2,8 kgf m.
Note: For engine models AP, AQ and AS with belt driven coolant pumps, either four tamper proof fasteners
or one tamper proof fastener and three flanged setscrews are used to retain the fuel pump gear. All Torx
screws are fitted with a special hardened flat washer. A special Torx socket part number 27610122 is needed
to remove and to fit these tamper proof fasteners, refer to your Perkins distributor. All other engine models
have four flanged setscrews to secure the gear.
9 Remove the timing pin.
10 Fit the gear cover to the cover of the timing case. For gear driven coolant pumps. Fit the coolant pump:
For early gear driven coolant pumps, see Operation 12-4.
For latest gear driven coolant pumps, see Operation 12-10.
Caution: Do not tighten the union nuts of the high-pressure pipes more than the recommended torque
tension. If there is a leakage from the union nut, ensure that the pipe is correctly aligned with the atomiser inlet.
Do not tighten the atomiser union nut more, as this can cause a restriction at the end of the pipe. This can
affect the fuel delivery.
11 Fit all the pipes. Connect the stop control and the control rod of the fuel injection pump. Fit the cables and
connection for the cold start device and electrical stop solenoid to the pump. Ensure that a spanner is used to
prevent movement of the pump outlets when the high-pressure pipes are fitted and tighten the union nuts to
22 Nm (16 lbf ft) 2,2 kgf m.
12 Eliminate air from the fuel system, see Operation 11-20.
13 Fit the cylinder head rocker cover.
14 Connect the battery.
15 Operate the engine and check for leakage. With the engine at the normal temperature of operation, check
that the idle speed and the maximum no-load speed are correct, see Operation 11-12.
