Chapter 8 FUEL SYSTEM
3.1.2 Fuel Injection Pump - Install
(a) Wash the bolt, bushing and washer before using. Foreign material on the contact surface of drive coupling and
laminated plates can cause the slipping or damage of coupling.
(b) After the tightening of couplings check the laminated plates for distortion. If the plates are distorted loosen and
retighten the bolts.
(1) Lift the fuel injection pump. Slowly lower the fuel
injection pump, and install the pump aligning with the
dowel pin on bracket.
(2) Couple the drive coupling to the cross coupling and ten-
tatively tighten the bolt.
Then, make sure that the line mark on the fuel injection
pump coupling (or timer) is at a position close to the
pointer when the No. 1 and No. 7 cylinders are at the
top dead center on compression.
(3) Adjust the distance between couplings to the specified
value.
For adjustment procedure, refer to "Coupling Distance -
Adjust" of "FUEL SYSTEM."
(4) Tighten all bolts and nuts, which have been installed
tentatively to the couplings, to the specified torque.
(5) Install the stay in between the fuel injection pump case
and the crankcase.
(6) Refill engine oil through the oil drain pipe mounting
hole of cam chamber.
(7) Install the oil pipe and fuel pipe.
3.1.3 Coupling Distance - Adjust
Adjust the position of coupling so that the distance between
couplings meet the specified value, and tighten the bolt to
the specified torque.
