Figure 8--7. Speed Control Solenoid
1) Solenoid Removal/Replacement
a. Disconnect wiring to solenoid. Disconnect linkage
arm (Item 4, Figure 8--7) from solenoid. Remove
mounting hardware from solenoid and then remove
solenoid.
b. Install replacement solenoid and mounting hardware.
Do not tighten at this time.
c. Attach linkage to solenoid and install the clip to the
linkage rod.
2) Low Speed Adjustment
a. Hold the speed lever against the low speed stop and
check the RPM. Adjust the low speed stop screw if
necessary.
b. Check engine speed using microprocessor data list.
c.Check for proper unit operation by running Pretrip (Re-
fer to Section 3.5).
3) High Speed Adjustment
a. Loosen but do not remove the 4--speed solenoid
mounting nuts.
b. Turn the jacking nut, allowing the solenoid to move
along the slots until the desired high speed is
reached. Tighten the solenoid mounting bolts and
verify correct high and low speed RPM.
c.Check for proper unit operation by running Pretrip (Re-
fer to Section 3.5).
8.6.6 Engine Air Cleaner
a. Inspection
The dry type air cleaner should be inspected regularly
for leaks. A damaged air cleaner or hose can seriously
affect the performance and life of the engine. The air
cleaner is designed to effectively remove contaminants
from the air stream entering the engine. An excessive
accumulation of these contaminants in the air cleaner
will impair its operation; therefore, a service schedule
should be set up and followed. The following simple
service steps are easily made while the engine is being
serviced in the field:
1. Check all connections for mechanical tightness. Be
sure cleaner outlet pipe is not fractured.
2. In case of leakage and if adjustment does not correct
the trouble, replace necessary parts or gaskets.
Swelled or distorted gaskets must always be re-
placed.
b. Air Cleaner Service Indicator
The air cleaner indicator is connected to the engine air
intake manifold and its function is to indicate when the
air cleaner requires replacing. When a plugged air
cleaner decreases intake manifold pressure to 20” (500
mm) WG, the indicator moves to the red line. The air
cleaner should be replaced and the indicator reset by
pressing the reset button.
c. Service Procedure
1. Stop the engine, remove air cleaner. Install new air
cleaner.
8.6.7 Engine Crankcase Breather
The engine uses a closed type breather with the
breather line attached to the cylinder head cover. (See
Figure 8--8)
The breather assembly should be cleaned once a year
or at every 3000 hours maintenance interval (whichever
comes first).
