Always start bolts by hand. Sub-assembly Figure 18E 38/86 NTB17-039 19. Install the original thrust bearing onto the primary pulley of the new sub-assembly (Figure 19E). CAUTION: The thrust bearing has two different sides. Reference Figure 19E for correct bearing orientation. Apply a thin layer of petroleum jelly or equivalent to the original thrust bearing to hold it in place on the primary pulley. Re-use the thrust bearing which was removed from the planetary carrier plate. Primary pulley Thrust bearing Figure 19E 20. Coat the primary pulley bearing, secondary pulley gear teeth and the secondary bearing with CVT fluid prior to installation (Figure 20E). IMPORTANT: Do NOT apply sealant to the case at this time. The sub-assembly will be sealed later in this procedure. The following Figures are for reference only and may or may not have the sealant in place, or have the old sealant removed. Clean the surfaces and apply sealant when and where instructed. Coat these surfaces with CVT fluid Figure 20E 21. Position the new sub-assembly over the CVT case and then lower it just far enough to allow the Guide Pins to be inserted into their appropriate sub-assembly holes (the Guide Pins are different lengths). NOTE: Guide pin locations are shown in Figure 9E on page 35. 39/86 NTB17-039 IMPORTANT: Before continuing, it is recommended that you review and understand the instructions on pages 40 to 45. Confirm dowel pins are clean – this will ease installation. The sub-assembly will lower into the CVT case without applying extra vertical force. IF THE SUB-ASSEMBLY DOES NOT LOWER COMPLETELY, INTERFERENCE IS PRESENT. ! PHYSICAL Key Technique: Raise to remove weight on interference, adjust as necessary, and then lower again. Use the “gap size” between the sub-assembly and the CVT case to determine the cause of interference. At any given gap, only 1 item will be the cause of interference 50 mm - Page 41 40 mm - Page 42 CASE GAP = ? 18 mm - Page 43 5 mm Page 44 Figure 21E Case gap Figure 22E 40/86 NTB17-039 22. Carefully lower the Lifting Fixture to install the sub-assembly into the CVT case as follows: While visually looking down into the bore (Figure 24E) to confirm that the output gear is clearing the CVT case bearing bore, a. Level the sub-assembly by placing hands on top to guide it into the CVT case. b. Lower the sub-assembly until a gap of 40 mm (1.6 inches) is present to the CVT case (Figure 27E on page 42) and then proceed to step 23. If the sub-assembly will not lower any farther than 50 mm (2 inches) the output gear has not cleared the bearing bore (Figure 24E). Sub-assembly will not lower past 50 mm (2 inches)? Interference is present between the output gear and bearing bore and are highlighted with yellow in Figure 23E and 24E.

Continue to slowly lower the sub-assembly into the CVT case. If the primary and the secondary pulley bearings do not align properly with their bores (Figure 28E) or are at an angle, a gap of 18 mm (0.7 inches) may be present. Possible areas of interference are highlighted with orange and tan in Figure 28E. As needed, level the sub-assembly as it is lowered into the CVT case to help the primary and the secondary pulley bearings align in their bores. MINOR LEVELING ADJUSTMENTS with limited weight on the sub-assembly will help the installation. Vertical force is not needed. Once the sub-assembly is LEVEL the primary and the secondary pulley bearings will smoothly align while lowering. Sub-assembly will not lower past 18 mm (0.7 inches)? If this occurs Do NOT force sub-assembly into case. a. Raise the sub-assembly slightly. b. Level the sub-assembly (visually check the gap between case and sub-assembly side cover and confirm that it is even all around). c. Gently lower the sub-assembly. d. Gently shake the sub-assembly horizontally, lower, raise and repeat as needed to help align. e. Lower to clear dowel pins to 6 mm (0.25 inches).
