10. Bolt the cylinder pot into position and feed the remain-
ing assembled cylinders through the openings in the
motor case and locate the inner end of the connecting
rods with the king rod fi xing with pin (29).

sembly.
12. Install spacing washer (30/34) and refer to the drawing
for spacing.
Spacing on the Motor – refer to drawing at right
Fit spacing washer so that A-B = 0.01 to 0.02 in. (0.25 to
0.50 mm) clearance
Crank Spacing Washers
0.128 in. (3.24 mm)
0.144 in. (3.66 mm)
0.160 in. (4.06 mm)
Measure dimension (A) from the crank washer face to
the motor case and also dimension (B) from the rotary
valve face to the inside of the gasket. Select the correct
shim washer from the list (31-34) to obtain the clearance
above.
Rotate the crankshaft until the balance weight is at the
bottom dead center position; rotate the rotary valve until
the balance weight is at the bottom position. Assemble the
valve housing (3) onto the motor case (27).
Rotate the output shaft in both directions and viewing the
rotary valve (2) through the exhaust cover (51) ensure that
the valve is correctly following the output shaft direction –
this checks that both the crank and valve slot are correctly
engaged.
Replace all drain plugs and refi ll the motor with oil. Spray
some light oil into the inlet and exhaust ports and connect
the unit to a low pressure air supply and run on the bench
for a short period before placing back into service.
