ASSEMBLY--BRAKE HUB ASSEMBLY (continued)

When all 28 camlocks (49) have been assembled, install one garter spring (48) so that it engages under the projecting

ends of the camlocks to force them into engagement with the sun gear (47) and the bore of the brake hub (44).

Install the remaining snap ring (50) in the bore of the brake hub (44) next to the camlock (49) ends.

Carefully turn the brake hub (44) and sun gear (47) assembly over so that it rests on the gear end of the brake hub. Be

careful that the brake hub does not slide off the sun gear.

When the brake hub (44) is turned over, allow the brake hub to slide off the sun gear (47) just enough so that the second

garter spring (48) can be installed under the projecting ends of the camlocks (49). Install the garter spring as described

in step 6.

10. Install 32 rollers (46) under the spacer (45) and between the brake hub (44) and the sun gear (47).

11. Slide the brake hub (44) back against the spacer (45) and turn the brake hub over so that it rests on the splined end of the

sun gear (47).

12. Install the remaining 32 rollers (46) between the brake hub (44) and the sun gear (47).

13. Install the spacer (45) and then the snap ring (43).

14. To check that the brake hub assembly (22) is assembled correctly, hold the gear end of the sun gear (47) with one hand

and view the end of the assembly while the gear teeth are away from you. With the other hand, try to rotate the brake hub

(44) in both directions. If the camlocks (49) have been assembled correctly, according to steps 5-13, the brake hub will

rotate freely in a clockwise direction and "lock up" in the opposite direction.

ASSEMBLY--PRIMARY PLANET ASSEMBLY

Lubricate the O-ring (42) with grease and install its groove in the thrust pad (41). Give the O-ring an additional coat of

grease and install the thrust pad in its recess in the inside wall of the planet hub (37) so that the slotted face of the thrust

pad is outward.

Press the thrust plug (38) into the ends of the primary planet pins (36).

Press the needle bearing (40) into the planet gear (39) so that the ends of the needle bearing are flush or slightly below

the side of the planet gear at each end.

Place the planet gear (39) into the planet hub (37) so that the bore of the bearing lines up with a planet pin hole.

Tap the primary planet pin (36) through the planet hub (37) until the drilled hole in the end of the primary planet pin lines

up with the hole in the rim of the planet hub.

Install the pin (35), and using a 3/16 inch diameter pin punch, drive the pin in until the outer end of the pin is 3/16 inch

below the outside diameter of the planet hub (37).

Repeat steps 1-6 for the remaining planet gears (39) and when they are installed, check that all the gears rotate freely.
