7. Lightly grease the connecting rod and components with O-ring lubricant.
8. Install the connecting rod into the motor axle (66).
9. Clamp the piston (57) into a bench vise.
10. Apply removable threadlock adhesive to the threads of the motor
axle (66).
11. Install the connecting rod (55) through the hole in the piston.
12. Screw the motor axle into the piston with a wrench.
13. Remove the piston from the bench vise.
14. Grease the outer rim and groove of the piston, then install the O-ring
(58) and guide ring (56) into the groove.
15. Grease the outside of the O-ring (58).
Cylinder Assembly
1. Install the cylinder (68) on the lower cylinder plate (74).
2. Evenly grease the inner wall of the cylinder with O-ring lubricant.
3. Grease the motor axle.
4. Press the piston into the cylinder, guiding the motor axle through the
lower cylinder plate, until the piston is just below the upper rim of the
cylinder. Use a rubber mallet if necessary.
5. Apply removable threadlock adhesive to the motor axle threads and
screw the coupler (see Figure 4, item 1) onto the axle.
6. Install O-rings (70, 73) onto each of the air inlet tubes (71), then lightly

Upper Cylinder Plate Assembly
1. Install the lower sintered bearing (51) into the bottom of the upper
cylinder plate (31).
2. Use retaining ring pliers to install the retaining ring (52) into the bottom
of the upper cylinder plate to secure the bearing.
3. Press the washer (53) onto the retaining ring (52).
4. Grease the lip seal (54), then install the lip seal on top of the washer, flat
side down so that the seal ridge fits into the groove in the upper cylinder
plate.
5. Install the upper cylinder plate onto the cylinder, fitting the air inlet
tubes (71) into the bottom of the upper cylinder plate.
6. Install the eight studs (45), 16 flat washers (30, 47), 16 lock washers
(29, 49), and 14 cap nuts and two ring nuts (not shown). Tighten the
