MOVING PARTS HAZARD

Air Motor and Throat Service

10.Pull the piston assembly from the air motor base (28), and set it aside.

11.Remove the throat bearing (36) with a 2-in. socket, remove the u-cup seal (10{), and wipe the seat clean with a cloth.

12.Remove the piston/base from the vise, and set it upright on the workbench.

13.Inspect the air motor for damaged or worn inlet valve grommets (17*), o-rings (19*, 20*), valve nuts (21*), lock wires (22*), exhaust valve poppets (26*), or inlet valve poppets (32*). If any of these parts need to be replaced, continue with steps 14 to 20. Otherwise, see Reassembly on page 12.

14.Use a screwdriver to push down on the trip rod yoke (13), and snap the toggles down. See Fig. 4.

Manual background WARNING

MOVING PARTS HAZARD

To reduce the risk of pinching or amputating your fingers, keep your

fingers clear of the toggle assemblies when you are snapping the toggles

(M in Fig. 4 ) up or down.

15.In this step, while you are prying with the screw- driver with one hand, cover the toggle assemblies with your other hand so as to catch the spring- loaded toggle assemblies when they snap out of the lugs. Place the tip of a screwdriver into the piston between the piston lugs (L) below the pivot pins (16) on the toggles, pry up with the screw- driver handle to compress the springs on the toggle assembly (M) up and away from the piston lugs, and remove the parts. See Fig. 4.

16.Straighten the lockwires (22*) and remove them from the valve nuts (21*). Screw the top nuts off. Remove the trip rod yoke (13), actuator (12), and trip rod (31). Unscrew the bottom nuts (21*), and remove the poppets. Make sure the valve bar spring clips (14) are not worn or damaged and that they properly guide the actuator (12).

17.Remove the exhaust valve poppets (26) by cutting them with a side cutter, then pull them out of the actuator (12).

18.Clean all the parts carefully in a compatible solvent and inspect them for wear or damage. Use all the repair kit parts during reassembly, and replace other parts as necessary.

19.Check the surfaces of the piston, piston rod, and cylinder wall for scratches or wear. A scored rod will cause premature packing wear and leaking.

20.Lubricate all parts with a light, waterproof grease.
