THRUSH AIRCRAFT, INC – MODEL S2RHG-T65 TURBO THRUSH

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.

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.

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)

Propeller in FEATHER

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.

Detach front clevis (Fig. 4-2, #6) at propeller reversing lever (Fig. 4-2, #2) by

removing retaining pin. Do not lose spacer.

Connect push-pull cable rear clevis (Fig. 3, Item 1) to center hole of propeller

cam (Fig. 3, Item 2).

Disconnect fuel governor interconnect rod (Figure 4-2, #14) from fuel governor

reset arm (Figure 4-2, #13) by removing retaining bolt.

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).

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.
