Place the 3/8 spacer (8) on the 1/2 bolt (11). Then insert the idler (12) followed by the 2-7/8 spacer (9). The idler must be recessed on the 2-7/8 bushing side as shown in Figure 3.32. 16. Install the belts onto the gearbox and engine pulleys, running on top of the idler. It may be necessary to over-center the motor mount to install the belts. See Table 3.10 for belt size and center-to-center distances (when engine over-center is in working position). Adjust engine position by sliding the engine mount Z-brackets. This will ensure proper belt tension. Tighten bolts. The BH 836 and BH 1036 augers do not have an idler. 17. Referring to Figure 3.28, adjust the motor pulley guard mount (1) so that the outside face is 5-7/8 (14.9 cm) away from the motor mount bracket (9) face and that the center slot is aligned horizontally with the shaft center on the engine. Tighten bolts. 18. Attach the outer belt guard (1) to the inner belt guard (2) by first inserting the top 1/4 x 5/8 self-tapping screw nearest the discharge end. Repeat for the top hole nearest the intake end. Do not insert the remaining screws. Refer to Figure 3.32. 19. Push the 1/2 bolt (11) the remainder of the way through the outer guard and tighten using the 1/2 nylock nut (10). See Figure 3.32. 20. Insert the remaining 1/4 x 5/8 self-tapping screws into the guard assembly. 21. Attach the outer belt guard (1) to the other 3/16 plate (7 or 7*) with a 3/8 x 1 bolt (16) and nut. DO NOT over-tighten, leaving the assembly free to pivot as shown in Figure 3.32. 22. Attach the intake end gearbox belt cover (3) using four 1/4 x 5/8 selftapping screws as shown in Figure 3.32. 23. Re-install the lower guard assembly over the upper guard and latch the rubber strap to secure. 46 30618 R1
