ENGINE CONTROLS
RIGGING INSTRUCTIONS
The following instructions will produce nominal settings of the engine’s operating
parameters. If an engine is installed, fuel control, propeller or propeller governor
replaced or any time the adjustment of these units is disturbed, the engine controls
rigging should be checked.
AIRFRAME CONTROL LINKAGES
Proper engine/airframe control system rigging is a prerequisite in order to achieve
satisfactory engine operation. The airframe control system will provide the required
throws, travel limits, and etc. necessary for the engine controls operation.
PROPELLER REVERSING INTERCONNECT LINKAGE
Details for assembly and disassembly of engine push-pull cable are contained in the
Engine Maintenance Manual.
** CAUTION **
Never attempt to move the power lever into reverse with
engine shutdown without first removing the pin at the rear
clevis. (Refer to Figure 4-3, item #1)
FRONT LINKAGE
A. Propeller in FEATHER
B. Align rig pin holes in propeller cambox and install pin (Fig. 3, See Rig Pin Hole. A
#41 drill bit can be used as a rig pin. This setting is a rigging datum point.
C. Detach front clevis (Fig. 4-2, #6) at propeller reversing lever (Fig. 4-2, #2) by
removing retaining pin. Do not lose spacer.
D. Connect push-pull cable rear clevis (Fig. 3, Item 1) to center hole of propeller
cam (Fig. 3, Item 2).
E. Disconnect fuel governor interconnect rod (Figure 4-2, #14) from fuel governor
reset arm (Figure 4-2, #13) by removing retaining bolt.
F. Position rear of clevis slot on beta valve Fig. 4-2, # (3) flush with front surface of
conical cap (1) on propeller governor (see rigging datum).
G. Apply forward tension on push-pull cable and while maintaining rigging datum
setting in step F, adjust clevis (Fig. 4-2, #6) so that retaining pin is easily installed
at clevis and reversing lever (Fig. 4-2, #2) interconnect. Ensure there is no slack
in the push-pull cable. If necessary, adjust length of cable on ball terminal ends
and on lever prior to completing connection and check clevis ends for safety;
cable must be of sufficient length to prevent the passage of lock wire through the
witness holes.
