over the spline of the rear reel arm so that the small notch is centred at the 3 o'clock position. Install the speed nuts (46) over the reel arm bearings with the convex side of the nuts away from the main plate. Press the speed nuts in place. b. Assemble the reverse take-up sprocket (43) and washers (44) and (45) onto the front reel arm shaft. Install the retainer (42) with the formed legs out, over the reel arm shaft and into the counterbore of the sprocket. Assemble the clutch cam (41) against the retainer so that the three notches in the cam straddle the three legs of the retainer. The shallow end of the notches must point in a counterclockwise direction. Rotate the cam counterclockwise against the legs of the retainer and insert a steel ball (40) between each of the three pairs of legs on the retainer. Insert the spring (39) into the radial slot of the cam so that the spring tends to rotate the cam in a clockwise direction. Install the rewind sprocket (37) and collar (36) onto the reel arm shaft so that the tongue of the collar enters the groove of the sprocket. Insert a 0.003 inch shim stock between the washers (45) and (44). Press all parts together and tighten 27 the set screws (35). Remove the shim stock. c. Assemble the rear reel arm parts in a manner similar to the front reel arm parts (step 'b') except that the shallow end of the notches in the cam (31) should point in a clockwise direction and the spring (29) must be installed so that it tends to rotate the cam in a counterclockwise direction. d. Refer to Figure 3. Install the reel arm lock plungers (41) springs (40) and brackets (39) with screws (38). The narrow portion of each lock plunger bar must rest on the flange of the reel arm lock discs. The groove in each bracket (39) must straddle the narrow portion of the bar. e. Install the timing belt over the small sprocket of the mechanism assembly, around the large sprocket of the front reel arm, and around the reel arm sprocket. Adjust the roller tension as instructed in paragraph 50. f. Perform all necessary adjustments and alignments as directed in the Adjustment section.
