Tilt Down
With the engine tilted up, the piston inside the accu-
mulator piston (d) will be at the bottom of the accumu-
lator (c) and the gas pressure is low. To lower the en-
gine, the camshaft lever (f) is rotated down, the
internal cam will cause the push rods to open the ac-
cumulator check valve (e), both fast transfer valves
(h & j) and the down slow transfer valve (i). The oper-
ator will have to press down on the engine cowl to
overcome the pressure inside cylinder. Fluid will flow
out of the bottom of the cylinder, past both the down
fast transfer valve (h) and down slow transfer valve
(i). Fluid will flow past the up fast transfer valve (j),
surge valve (k) and through the interconnecting pas-
sage into the top of the cylinder (l). Due to the shock
rod (a), the tilt cylinder cavities differ in volume, the
extra fluid from the up cavity [forced into the accumu-
lator (c)] will cause the internal accumulator piston (d)
to compress the gas. With the engine in the correct
position, the camshaft lever is rotated up and the
push rods allow the check valves (e, h, i, & j) to close.
