General Information

Introduction
This manual provides installation instructions for mounting the engine related compressor components. Read this manual prior to servicing or operating the compressor system.
Follow all safety precautions when servicing or operating the VMAC system.
Proper service and repair are important to the safety of the operator and the safe, reliable operation of the equipment. Always use genuine VMAC replacement parts.
The procedures described in this manual are the only approved methods of service and operation.
Torque Specifications
All fasteners must be torqued to specifications. Use manufacturers’ torque values when available. Apply Loctite 242 (blue) or equivalent on all fasteners subject to vibration.
Torque values below are typical to achieve 70% yield strength of the bolt with Loctite applied (or otherwise lightly lubricated).
This assumes the mating threads are of sufficient strength. Reduce values as needed based on thread engagement length and material.

Moving Parts Hazard

• Before performing service, disconnect the power source to prevent unexpected equipment
• Do not operate the system without guards in If the guards are damaged or missing, replace them before operating the equipment.

Electrical Hazard

• Ensure the ground point connection is connected to the equipment body/chassis to prevent the chance of injury.
• Ensure the equipment is grounded appropriately

Burn Hazard

• The compressor system gets very hot during operation, contact with the components or the oil can cause serious injury. Allow sufficient time for the system to cool prior to performing
• Never allow any part of your body to contact the compressor components until the system has cooled sufficiently.

Compressor Air and Oil Hazard

• The compressor system is under sufficient pressure that a leak could force the air/oil mixture through the skin directly into your This could cause serious injury or death.
• Ensure the system is completely depressurized before attempting maintenance or repair.
• Do not use compressed air to clean off clothing or skin, compressed air can penetrate the skin causing serious injury or death.
• Do not move or service the system while it is pressurized or operating.
• Components and hoses under pressure could separate suddenly and cause serious injury or death. If equipped, the air receiver tank must be drained prior to servicing the system.
• Never adjust or attempt to make any repairs to the system while the engine is running. Components and hoses under pressure could fail and cause serious injury or death.

Burst Hazard

• Serious injury or death may result from an air tank explosion.
• Never exceed manufacturer’s maximum air pressure rating.
• Do not repair components, only replace with approved parts.
• Do not tamper with, or disable factory safety equipment.

Personal Safety

• Vaporized oil is a respiratory hazard, do not breathe the compressor air.
• Always use the appropriate personal protective equipment, particularly eye and hearing protection when operating air powered equipment.

Main Bracket and Compressor Installation

Apply Loctite 242 (blue) to all fasteners.

• Mount the pulley (P/N 1800282) to the engine using six M12x30 bolts (P/N 1520624) and Loctite.
• Torque the six M12 bolts to 74 ft-lb (100 N•m) as per Table 1 on page 6.
• Mount the main bracket assembly (P/N 4800883) to the engine using four M12x80 bolts (P/N 1520682) and Loctite. Leave bolts finger tight.
• Install one M16x110 bolt and washer (P/N 1520683 and 1570233), this will press-in the bushing included in bracket assembly (P/N 5800200) until it contacts engine mount face.
• Torque the four M12 bolts to 74 ft-lb (100 N•m) as per Table 1 on page 6.
• Torque the M16 bolt to 183 ft- lb (248 N•m) as per Table 1 on page 6.
• Mount the compressor (P/N P120218) onto the main bracket using four M8x110 bolts (P/N 1540521) and Loctite.
• Torque all four compressor bolts to 19 ft-lb (25 N•m) as per Table 1 on page 6.
• Install the belt (P/N 1610378) and route as per the figure below.
• Remove the tensioner locking pin using a 3/8” drive to rotate the tensioner.

Ensure belt is located correctly on all tensioners, pulleys, and idlers.
Failure to mount the belt correctly could damage or throw the belt on start- up, creating a safety hazard and or personal injury.
