Apply Doubrex 251 grease to the inner circumference of Holder Sleeve (B) [14] and the cam groove of Plunger (A) Set [32]. Mount Washer (E) [1], Thrust Bearing [21], Washer (D) [20], Spring (A) [19], Dust Washer [18], Guide Washer [17], Holder Sleeve (C) [16], Holder Sleeve (B) [14] and Holder Sleeve (A) [13] in the Plunger (A) Set [32] through the tip in order (Fig. 15).

Next, align the hole of the Plunger (A) Set [32] with the notches of Holder Sleeve (A) [13] and Holder Sleeve

Turn them about 90˚ counterclockwise viewing from the tip (as shown in B Fig. 16), then insert the two Steel Balls D4.76 [15] (in the direction of the arrow marks shown in Figs. 16 and 17). Slide all the parts up to Washer (E) [1] forward (as
