M8X1.25x20mm socket head cap screws [23]. Be sure that the supplied o-ring [16] is properly seated
in the cam thrust plate before installation. Torque the bolts to 27 ft-lbs.
Step 3: Slide the AXK4565 rearward thrust bearing [40] and AS4565 washers [38] over the shoulder
on the back of the cam gear [2]. Install the proper cam degree bushing [45] and install the gear onto
the cam using the three supplied M8X1.25x35mm socket head cap screws [27]. Torque the bolts to 27
ft-lbs.
