a) The system should work with minimal friction.
Regularly clean
and lubricate racks, bearings (also self-lubricating bearings
(8)) and ball joints with lubricating oil.
b) The system should be as free from clearances
as possible.
Check clearances of all connections. Total clearance may cor-
respond to max. 0.5 mm of injection pump fuel rack positions.
c) Check regularly
(see recommendations in chapter 04.) the
adjustment of the system; stop position, overspeed trip devices
and starting fuel limiter, see section 22.3.
d) When reassembling the system,
check that all details are
placed in the right position, that all nuts are properly tightened
and to torque, if so prescribed, and that all locking elements
like pins, retainer rings, locking plates are in their positions.
Check according to pos. a) - c).
22.3 Check and adjustment
22.3.1 Stop lever stop position
a) Check:
·
Set the terminal shaft lever (3) in the maximum fuel position
and the stop lever (16) in the stop position.
·
Check that the fuel rack position of all injection pumps is
maximum 5 mm.
b) Adjustment:
·
Set the stop lever in the stop position and check that the
lever (9) contacts the dog (18) properly. A small torque can
be set from the governor, but not a too large one, because this
will twist the shaft unnecessarily, although little.
·
Adjust the fuel rack position to 5 mm by adjusting the screws
(14).
22.3.2 Governor stop position
a) Check:
·
Move stop lever into work position.
·
Set the governor terminal shaft lever in the stop position.
·
Check that the fuel rack positions are 2 mm.
b) Adjustment:
·
If the fuel rack positions are unequal, adjust first according
to section 22.3.1b).
·
Adjust the link rod so that the fuel rack position of 2 mm is
obtained.
·
If changing the governor, see section 22.4.
