GEARBOX - PNEUMATIC SECTION
2-5
Operation
Gearbox in neutral:
In the neutral position, thrust pin A will be
pushed into a recess in the selector shaft by
means of the air pressure coming from
connection 1 and a bore hole through sealing
pin B. Sealing pin B will provide a spring-loaded
seal on seat C. The air flow can now leave the
valve via connection 21 and subsequently
operate the range cylinder through the
electropneumatic valve.

Gearbox engaged:
When a gear has been engaged, the selector
shaft will push the thrust pin A up against
sealing pin B. This closes off the bore hole in
this pin and causes the pin to be lifted of seat C
against the spring pressure. The air pressure in
the gear engaging cylinder can now flow back to
the neutral valve via the electropneumatic valve
and leave the valve housing through the bleed
opening (3).
