If a new belt is installed, check the belt adjustment after 30 minutes of operation. A belt is considered used after 30 minutes of operation.

1. Stop the engine in order to inspect the belt.

2. Open the engine access door. Refer to Operation and Maintenance Manual, “Access Doors and Covers”.

3. Loosen the quarter-turn fasteners (1) on the front of the guard.

4. Remove the guard for the V-belt.

5. Inspect the condition of the belt and the adjustment of the belt. The belt should deflect 10 mm (0.39 inch) to 12 mm (0.47 inch) under a straight pull of 10 kg (22 lb). This measurement should be taken between the alternator pulley and the crankshaft pulley.

Note: A 144-0235 Borroughs Belt Tension Gauge may be used to measure belt tension. This measurement should be taken between the alternator pulley and the crankshaft pulley. Refer to the following table for belt tension.

6. Loosen the mounting bolt (4). Loosen the adjusting bolt (5).

Warning: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

NOTICE: Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.

Warning: Personal injury or death can result without releasing all of the hydraulic pressure. Release all the pressure from the hydraulic system before any lines are disconnected.

Personal injury can result from contact with refrigerant. Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury. Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant.

Personal injury or death can result from inhaling refrigerant through a lit cigarette. Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death. Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.

NOTICE: If the refrigerant system has been open to the outside air (without being plugged) for more than 30 minutes, the receiver-dryer must be replaced. Moisture will enter an open refrigerant system and cause corrosion which will lead to component failure.
