DRUM DRIVE BELT REPLACEMENT -- Continued
0117 00
INSTALLATION
1. Install drive belt (14) onto drive sheave (15) and drum sheave (16) as follows:
a. Install drive belt (14) onto drive sheave (16).
b. Push inward on drive belt (14) at belt entry point (17) on drum sheave (16).
c. Slowly rotate drum sheave (16) while continuing to push inward on drive belt (14) until drive belt slips onto
sheaves (15) and (16).
2. Loosen six screws (18) securing mounting angle (19) to mounting plate (20).
3. Check sheave alignment as follows:
a. Place a straight edge (21) across contact points (22) on sheaves (15) and (16).
b. Check for a gap between any contact points (22) and straight edge (21).
c. Repeat steps a and b for opposite side of sheaves. If a gap is present, continue to step 4, otherwise proceed
to step 6.
4. Loosen jam nuts (23) on four adjusting screws (24).
5. Tighten or loosen adjusting screws (24) to move motor mounting plate (25) up or down until correct sheave
alignment is obtained.
6. Check drive belt tension as follows:
a. Grasp belt (14) approximately halfway between sheaves (15) and (16).
b. Move belt (14) in from neutral position to check deflection in both directions.
c. If belt deflection is not 3/8 to 5/8 inches in both directions continue to step 7, otherwise proceed to step 9.
NOTE
When adjusting belt deflection the motor mounting plate must be raised or lowered
evenly with all four adjusting screws otherwise the sheaves will have to be realigned.
7. Tighten or loosen adjusting screws (24) to move motor mounting plate (25) up or down until correct belt
deflection is obtained.
8. Recheck sheave alignment and belt deflection following steps 3 and 6.
9. Tighten jam nuts (23).
10. Tighten six screws (18) securing mounting angle (19) to mounting plate (20).
11. Install front belt guard (12) onto rear belt guard (13), then secure with eight screws (10) and lock washers (11).
NOTE
Steps 12 thru 15 apply to drum A only.
12. Install pipe (9) then tighten unions (7) and (8).
13. Install pipe (6) then tighten unions (4) and (5).
14. Connect water supply line (3).
15. Plug water supply pump (1) into junction box (2).
16. Use maintenance menu to test drum rotation in both directions and at all speeds (WP 0010 00). Ensure drum
rotates freely and smoothly.
17. Perform a test laundry cycle (TM 10--3510--221--10). Check for leaks at any disconnected water connections.
