5 Carefully rotate the gear (C6) counter-clockwise until the backlash between the idler gear and the fuel pump
gear has been removed. Do not rotate the crankshaft or it will be necessary to set TDC again.
6 Tighten the four fasteners (D or E) that retain the gear to 28 Nm (20 Ibf ft) 2,8 kgf m. Remove the timing pin.
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 (D3) 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.
7 If a new gear has been fitted, use a feeler gauge to check the backlash.
8 Fit the timing case cover, see Operation 6-2.
