CAUTION
Excessive force when placing tension on the standby motor to compressor V-belt
may cause damage to the standby motor. Use hand force only to apply tension. Do
not use pry bar or any other mechanical tool to apply tension to the standby motor to
compressor V-belt during installation or adjustment procedures.
12. Install new idler assembly shaft (Figure 3, Item 7) through idler pulley (Figure 3, Item 8) and bracket (Figure 3,
Item 4)
13. Install idler (Figure 3, Item 3) and washer (Figure 3, Item 6) onto idler assembly shaft (Figure 3, Item 7) and
secure in place using new lock nut (Figure 3, Item 5).
NOTE
Adjustment of the tensioner adjustment bolt will be accomplished during the
reinstallation of the engine to compressor V-belt.
14. Install tensioner adjustment bolt (Figure 3, Item 1) and nut (Figure 3, Item 2) through bracket (Figure 3, Item 4)
and into idler (Figure 3, Item 3).
15. Use hand pressure to put 30-50 pounds tension on new V-belts (Figure 3, Item 2).
NOTE
When checking V-belt tension using the V-belt tension gauge, place the tension
gauge as close to midpoint as possible between sheaves.
Proper tension for a V-belt is considered to be the lowest allowable tension that the
belt will not slip at during peak load conditions.
16. Check V-belts (Figure 4, Item 2) tension using belt tension gauge. V-belt tension should be 30-50 pounds.
17. Adjust tension of V-belts (Figure 4, Item 2) as needed to achieve tension of 30-50 pounds.
NOTE
New V-belt tension drops rapidly during the first few hours of operation. Check and
re-verify proper V-belt tension every four hours during the first 24-hours of operation
after replacing the belt.
18. Install top-middle panel (WP 0013, Install).
19. Install top-left panel (WP 0013, Install).
20. Place emergency stop switch (Figure 2, Item 1) in PULL TO START position.
21. Exit top of MTRCS.
22. Connect negative (-) battery terminal (WP 0053, Reconnect).
23. Place POWER ON/DOWN switch (Figure 1, Item 2) on control panel to ON position.
24. Operate MTRCS to verify proper operation (TM 10-8415-222-10, Operating Procedures).
25. Place MTRCS back into desired mode of operation (TM 10-8415-222-10, Operating Procedures).
