5-5. MAINTENANCE OF FUEL INJECTION PUMP - (Cont)
(g) Take off blocking device from fuel feed line. Make sure fuel emerges from spill device absolutely
bubble free into suitable container.
(2) Perform adjustment of delivery end as follows:
(a)
(b)
(c)
(d)
(e)
Turn flywheel in direction of rotation (CCW) until fuel stops to emerge from adapter device. Then
turn again very slowly and carefully until fuel just begins to emerge. This position is the end of
delivery on which the timing gauge has to be set to “0”.
Check the flywheel for degrees before TDC (OT). If degrees are between 45 and 47, timing is
correct. If degrees are below 46 degrees go to step (c). If degrees are more than 47 degrees, go
to step (d).
Add shims as follows:
1 Turn engine where flywheel is at 46-47° before TDC.
2 Observe timing gauge for determining the exact thickness of shims to be added or removed.
3 Remove injection pump IAW step a.
4 Install injection pump IAW step b.
Remove shims as follows:
1 Turn engine where flywheel is at 46-47° before TDC.
2 Observe timing gauge for determining the exact thickness of shims to be added or removed.
3 Remove injection pump IAW step a.
4 Install injection pump IAW step b.
Recheck adjustment of delivery end.
(3) Remove spill device as follows:
(a) Clamp fuel feed line (1).
(b) Remove spill device (9) with washer (6).
(c) Insert pressure valve (7) into pressure valve body (8).
(d) Install washer (6), spring (5), filling piece with three shims (4), and delivery valve holder (3).
(e) Remove clamp from fuel feed line (1).
