Installation of the nosewheel is the opposite of removal. Tighten the 5/16 inch elastic stop
nuts until the wheel bearings just begin to bind, then back off until the bearings are just free.
Service the nosewheel oleo strut
as follows:
1.
Remove the strut valve from the top of the oleo.
2.
With strut compressed, fill with hydraulic oil per Section I.
3.
Extend and compress strut several times to expel air. Refill to top with oil.
4.
Install strut valve.
5.
Lower tail and raise nosewheel off ground.
6.
Open strut valve and pump up with air (or nitrogen) to 125-150 psi (sufficient to fully ex-
tend strut with nosewheel off ground).
7.
Lower nosewheel to ground and bleed pressure through strut valve until strut is ex-
tended two to three inches with normal weight on the nosewheel.
8.
Close strut valve and safety wire to steering yoke bolt and bearing nut.
POWER PLANT SYSTEM
The power plant system consists of the engine, engine mount, propeller, cowl, engine con-
trols, exhaust, air intake system and fuel system.
ENGINE:
Engine instructions covering the care and operation are covered in the engine manufac-
turer’s Operator’s Manual.
PROPELLER:
The propeller manufacturer’s Installation, Operation and Service manual contains infor-
mation on the proper use and care of the propeller.
ENGINE MOUNT:
The engine mount is a welded structure of chrome molybdenum steel (4130) tubing. The
engine is attached to the mount by means of four point suspension to four (4) mounting pads
on the engine case. Each leg attachment incorporates a shock mount designed to absorb tor-
sional fluctuation and vibrations of the engine. The engine mount assembly is bolted at the
firewall to the fuselage structure by means of four (4) 3/8” attaching bolts, (requiring a torque of
13.3-15.8 ft. lbs.) which should be checked for tightness periodically.
