8.
Rocker arms and shafts inspection procedures:
Inspect rocker arm shafts and bushings for wear. Maximum shaft to bushing clearance is 0.004 inch
(0.10 mm).
9.
Injector tube leak test and replacement procedures:
Replace injector tubes if found leaking during pressure test as follows:
(1)
Place bearing and bushing inserter (Figure 17, Item 85) in injector tube (Figure 17, Item 84).
(2)
Insert pilot (Figure 17, Item 82) in small hole in injector tube (Figure 17, Item 84) and thread pilot
in threaded hole of bearing and bushing inserter (Figure 17, Item 85).
(3)
Tap pilot (Figure 17, Item 82) to drive out injector tube (Figure 17, Item 84). Lift injector tube,
pilot, preformed packing (Figure 17, Item 83), and bearing and bushing inserter
(Figure 17, Item 85) from cylinder head. Discard injector tube and preformed packing.
(4)
Thoroughly clean injector tube hole in cylinder head to remove dirt, burrs, or foreign material that
may prevent tube from seating properly.
(5)
Lubricate injector tube preformed packing (Figure 17, Item 83) with engine oil and place in
counterbore of cylinder head.
NOTE
There are two types of injector tube installers, a fixed tool
(Figure 17, Item 85) for the superseded tube and an adjustable tool
(Figure 17, Item 87) for the current tube. The current tube has “606"
stamped on top flange. Either injector tube is acceptable if used with the
proper installer.
For proper installation of current injector tube, adjustable injector tube
installer must contact bottom of injector tube before it touches flange at
top. Clearance at top, between flange and tool, must be 0.001–0.010 inch
(0.03–0.25 mm).
(6)
Place bearing and bushing inserter (Figure 17, Items 85 or 87) in injector tube
(Figure 17, Item 84). Insert pilot (Figure 17, Item 82) through small hole in injector tube and
thread into tapped hole at end of installer.
(7)
Slip injector tube (Figure 17, Item 84), bearing and bushing inserter (Figure 17, Item 85 or 87),
and pilot (Figure 17, Item 82), into injector bore and drive into place.
(8)
Turn cylinder head fire deck up and remove installer pilot. Thread flaring die installer
(Figure 17, Item 86) into tapped hole of bearing and bushing inserter (Figure 17, Item 85 or 87).
(9)
Apply 30 lb-ft (41 N·m) torque to flaring die installer (Figure 17, Item 86).
(10) Remove flaring die installer (Figure 17, Item 86) and bearing and bushing inserter
(Figure 17, Item 85 or 87) from injector tube.
