Landing Gear Servicing

Serials 3915 thru 4030, 4032, 4045 before SB2X-32-21: The main
landing gear wheel assemblies use 15 x 6.00 x 6 tires and tubes. The
nose wheel assembly uses a 5.00 x 5 tire and tube.
Serials 3915 thru 4030, 4032, 4045 after SB2X-32-21, 4031, 4033 thru
4044, 4046 & subs: The main landing gear wheel assemblies use 15 x
6.00 x 6 tubeless tires. The nose wheel assembly uses a 5.00 x 5
tubeless tire.
All Serials: Always keep tires inflated to the rated pressure to obtain
optimum performance and maximum service. The landing gear struts
do not require servicing. With the exception of replenishing brake fluid,
wheel and brake servicing must be accomplished in accordance with
AMM procedures.

Brake Servicing

Brake Replenishing
Serials 3915 thru 4030, 4032, 4045 before SB2X-32-21: The brake
system is filled with MIL-H-5606 hydraulic brake fluid.
Serials 3915 thru 4030, 4032, 4045 after SB2X-32-21, 4031, 4033 thru
4044, 4046 & subs: The brake system is filled with MIL-PRF-87257
hydraulic brake fluid.
All Serials: The fluid level should be checked at every oil change and at
the annual/100-hour inspection, replenishing the system when
necessary. The brake reservoir is located on the right side of the battery
support frame. If the entire system must be refilled, refer to the AMM.
To replenish brake fluid:
1. Chock tires and release parking brake.
2. Remove top engine cowling to gain access to hydraulic fluid
reservoir.
3. Clean reservoir cap and area around cap before opening reservoir
cap.
4. Remove cap and add appropriate hydraulic fluid as necessary to
fill reservoir.
5. Install cap, inspect area for leaks, and then install and secure
engine cowling.
