4. Grease both ends of the piston (102) and install

it in the housing (101), with the flat side toward

the cup. Be careful not to tear u-cups (108) when

sliding piston into housing.

5. Standard Models: Grease new o-rings (106) and

install on the end caps (107). Install the end caps

into the housing.

DataTrak Models: Orient the air valve so the air

inlet faces forward. Grease and install new o-ring

(106) on right-side end cap (107). Grease and

install new o-ring (106) and the solenoid release

button (118) and o-ring (119) on the left-side end

cap (117). Install the end caps into the housing.

6. Install a retaining ring (110) on each end to hold

caps in place.

7. Grease and install the detent assembly (103) into

the piston.

8. 4D150 Models: Install the spring (111). Grease

the side of the air valve cup (112) that will contact

the valve plate (105) Install the air valve cup

(112). Align the small round magnet (B) with the

air inlet.

4D350 Models: Install the o-ring (113) on the

cup (112). Apply a light film of grease to the

outside surface of the o-ring and the inside

mating surface of the base (114). Orient the end

of the base that has a magnet toward the end of

the cup that has the larger cutout. Engage the

opposite end of the parts. Leave the end with

the magnet free. Tilt the base toward the cup

and fully engage the parts, using care so that the

o-ring remains in place. Install the spring (111)

onto the protrusion on the cup. align the magnet

in the base with the air inlet and install the cup

assembly.

9. Grease the cup side, and install the valve plate

(105). Align the small hole (A) in the plate with

the air inlet. Tighten the screws (109) to hold it

in place.
