BLEEDING
FOR STEERING GEAR VERSIONS WITH AUTOMATIC BLEEDING
Steering gear versions with automatic bleeding do not have any bleed screws. These steering gears automati-
cally bleed any air remaining within the steering system. Proceed as follows :
a) Lift the front of the vehicle from under the axle so that the wheels are not on the ground and can be
turned with the steering wheel.
Use a pair of low profile jack stands to support the front axle beam.
Always place safety stands when working under the vehicle. Refer to Maintenance Instruction MI14-01B Hoisting
and Towing Procedure for NYCT X3-45 Commuter Buses for further details on lifting procedures and safe lifting
practices.
b) Start the engine and have it run at idling speed for 2-3 minutes. Ask a colleague to turn the wheel from
one knuckle stop to the other until the effort needed is constant, so the air will be evacuated by the
steering fluid reservoir. Monitor the fluid level in the tank.
c) After bleeding, fill the tank up to 1" from the top of the tank. Check the fluid level with the dipstick.
DANGER
DO NOT work near the fan with the engine run-
ning. The engine fan can engage at any time
without warning. Anyone near the fan when it
turns on could be seriously injured.
WARNING
Never attempt adjustments while the engine is
running unless otherwise specified for the ser-
vice procedure. To help prevent an accident
caused by moving parts, work carefully around
them. Guards, covers and shields should be in
place whenever maintenance is not being per-
formed. Keep objects away from moving fan
blades. They will throw or cut any object or tool
that falls or is pushed into them.
