Preparation ofcold start device

1. Turn coldstart device linkage clockwise.
2. Set asuitable block[Thickness: about15mm (0.59 in)]
between coldstart device plunger andlinkage rod.
3. Turn crankshaft 2turns clockwise toset the device tonor-
mal position.

Checking
1. Set NO.1 piston atTDC onitscompression stroke.
TDC: Without paintedmark
2. Remove injection tubesandairbleeder onthe back ofinjec-
tion pump.
3. Set dial gauge soitsindicator pointstosomewhere between
1.0 and 2.0mm (0.039 and0.079 in)onthe scale.
4. Turn crankshaft 1turn clockwise andcheck thatdialgauge
indicates thesame value again.
5. Turn crankshaft counterclockwise about20to25 degrees,
then setdial gauge indicator to0mm (0in).
6. Turn crankshaft clockwiseandsetthe pump timing markto
the mark onthe crankshaft pulley.

7. Read plunger lift.
Plunger lift:

mark
• When repeating thechecking, startwithstep 5.

Adjusting
1. Ifplunger liftisnot within thespecified value,adjust by
turning injection pump.
• Ifindication issmaller thanthespecified value,turnpump
body away fromengine.
• Ifindication islarger thanthespecified value,turnpump
body towards engine.
2. Tighten injection pumpsecuring boltsandnuts.
Nut:
~: 13-18 N.m (1.3-1.8 kg-m, 9-13 ft-Ib)
Bolt:
~: 49-59 N.m (5.0-6.0 kg-m, 36-43 ft-Ib)
3. Remove dialgauge andinstall airbleeder withnewwasher.
4. Install injection tubes.
Flare nut:
~: 22-25 N.m (2.2-2.5 kg-m, 16-18 ft-Ib)
5. Bleed airfrom fuelsystem.
