7.7 LANDING GEAR
The thrce landing gcars use Cl€veland 6.00 x 6 wheels, the main gear
wheels (Figure 7-l) b€ing provided with brake drums and Clevcland single
disc hydraulic brake assemblies. All three wheels use 6.00 x 6, four-ply
rating, Type III tires with tubes.
A spring device is incorporated in th€ rudder pedal lorque rube
assembly to provide rudder trim. A bungee in the nose gear srcering
m€chanism reduces st.ering effort and dampcns bumps and shocks during
taxiing. By using the ruddcr pedals and brakes rhe nose gear is sreerable
through a 30 degree arc each side of€€nt€r. Later aircraft have the bungee
removed from the nose gear steering mechanism and aresteerable througha
20 degree arc each side ofcenter. A shimmy dampeneris also included in the
nose gear,
The three struts are of the air-oil type, with a normal extension of3.25
inch€s for th€ nose gear and 4.50 inches for the main gear.
Th€ standard brak€ system consists of dual toe brakes atta€hed !o the
rudder pedals and a hand lever and master cylinder located below and
behind the left center of the instrument sub-panel. Th€ toe brakes and the
hand brake have their own brake cylinders, but they share a €ommon
reservoir. The brak€ fluid reservoir is installed on the top lefi front face of
the fire wall. Th€ parking brake is incorporated in the masrercylinder and is
acruated by pulling back onrh€brak€ lev€r, dep ressing the knob attached to
the l€ft sid€ of the handle, and releasing lh€ brak€ l€ver. To release the
parking brake, pull back on the brake lever to disengage the catch
mechanism and allow the handle to swing forward (ref€r to Figure 7-5).
