Matching marks on timing gearsTo install the accessories, follow the reverse of removal procedure, and take the following steps:(a) Installing fuel injection pump When installing the pump, make sure that matching marks on pump drive gear and other gears are aligned with those on idler gear respectively, as shown. With these matching marks are all aligned, No. 1 cylinder piston is at top dead center on compression stroke.(b) Refill the engine with recommended oil up to the specified level.(c) Refill the cooling system with coolant.(d) Check each pipe connection for oil or coolant leaks.(e) Prime the fuel system.(f) After installing the fuel injection pumps, inspect and adjust the injection timing.
