Connecting Rod/Eccentric Assembly
8. Rotate shaft to align the eccentric's set screw

with the access hole in the bottom of the com-
pressor housing.

9. Insert the 5/32-inch allen wrench into the access

hole in the bottom of the compressor housing.

10. Loosen the setscrew 1/4 turn.

11. Rotate connecting rod to top dead center (180

0

)

and slide the connecting rod/eccentric assem-
bly off the shaft.

12. Secure the rod assembly in a fixture.

13. Remove the sleeve from the connecting rod and

discard.

Piston Cup
14. Remove the screw (discard) from the cup re-

tainer (retain for reassembly).

15. Remove the piston cup (discard) and wipe de-

bris from the top of the connecting rod with a
clean damp cloth.

O-ring, Intake Valve and Valve Keeper
16. Remove the O-ring, intake valve and valve

keeper from the bottom of the valve plate. Dis-
card all.

17. Clean the bottom of the valve plate with a clean,

soft cloth.

Exhaust Flapper Valve, Valve Restraint and Valve Keeper
18. Remove the exhaust flapper valve, valve restraint and

valve keeper from the top of the valve plate. Discard all.

19. Clean the top of the plate with a clean, soft cloth.

Gasket
20. Remove the OLD gasket from the top of the valve

plate and discard.

21. Clean the valve plate with a clean, soft cloth.

REBUILDING COMPRESSOR 

(REFER TO FIGURE 15).

NOTE: Before reassembly, wipe any residue from
all components with a clean soft cloth.

Gasket
1. Install NEW gasket; seating the gasket firmly in

the groove at the top of the valve plate with your
finger or blunt object.

CAUTION

Make sure that the O-ring is NOT twisted when
seated in the groove of the top of the valve plate.

O-ring, Intake Valve and Valve Keeper
3. Install the NEW valve keeper on top of the NEW intake

flapper so that the word "UP" is visible (FIGURE 17).

4. Install the NEW O-ring, seating it firmly into the grove

with your finger or blunt object.

NOTE: Torque flapper screws to 18 inch-lbs.

Piston Cup

5. Place cylinder sleeve over rod top with smooth edge

facing up.

6. Place piston cup on rod top making sure it is CEN-

TERED.

7. Place retainer on top of piston cup and seat retainer in

rod top pocket, making sure the retainer and cup lineup
properly along with screw holes.

8. Insert new screw into rod top and torque to 65 inch-lbs.
