DF140 “K2” (’02) MODEL 11-43
SHOCK ABSORBER CIRCUIT
This incorporated safety feature is for protection of the gearcase and prevention of internal PTT pressure
build-up in the event of an impact.
(1) The pressure from a sudden impact will make impact relief valve I open, allowing oil from the upper area
of the tilt cylinder to flow into the area between the tilt rod piston and the free piston. The tilt rod will then
extend.
(2) When the moment of impact has passed, the PTT DOWN switch must be activated to return the engine to
within the normal trim range. When the switch is pressed, the oil between the piston and free piston will be
directed to the cylinder upper chamber via the return valve below the tilt piston.
