16. Install two lip seals (38) in the two pistons (39). Make sure the lip of the seals point up as shown. 17. Install two pistons (39) into housing (40). Use tooling (B) to hold the lower piston and one plate (37) as shown. Be sure the small holes in plate (37) are in alignment with rods (34). Install housing (40). 18. Install the orifice in the other end of shaft (41) to a depth of 1.25 0.25 mm (.050 0.010 in.).19. Use tooling (A), and install bearing (42) to a depth of 2.25 0.25 mm (.088 0.010 in.). The diameter of bearing (42) after assembly must be 25.394 0.039 mm (1.0000 .0020).20. Install bearing (43) with dowel (44) in alignment with the notch in bearing (43). 21. Install spacer (45), gear (46) and snap ring (47). 22. Assemble gear (48) to carrier (49) with the lockring.
Be sure the rubber in pins (52) that hold the shafts in the carrier is not damaged. If the rubber is damaged, a replacement of the pins must be made.
23. Install bearing (54), gear (53), two washers (51) and shaft (50) into carrier (49). Secure the shaft in the carrier with pin (52). 24. Install the planetary and gear assembly on the shaft assembly. Install plate (55), and secure it with roll pin (56). 25. Turn the shaft and planetary assemblies over, and install gear (57). Install the first plate (59) upsidedown with the small holes in alignment with rods (34) as shown.26. Install shaft and planetary assembly (58) as a unit. Install four plates (59) and four discs (60). Alternate plates and discs starting with a plate. 27. Assemble plate (61) to gear (62) with the lockring, and install it on the transmission.28. Install plate (63). 29. Install hub (64) and snap ring (65). 30. Install five discs (66) and four plates (67). Alternate discs and plates starting with a disc.

Figure 2. Wrong Method To Make (Non-Metalic) New Seal Rings Ready For Installation.
New seal rings must be preloaded before they are installed to prevent them from being damaged or broken when the clutch housing is installed. There is a correct method to preload new seal rings prior to installation. Place your hands on each end of the seal ring, and pull (wind) the ends several inches past each other or until they almost make contact. See Figure 1. Use care to keep the ring shaped like a circle. This will make an even bend (or ring "set") all around the ring. When the seal ring is in the groove, the ends must butt together lightly. Do not bend the seal ring as shown in Figure 2. This does not make an even bend all the way around the ring.Do not attempt to use this method to preload a used seal ring. Also, do not use this procedure for cast iron seal rings. This
