Accessory Drive - Overview

OVERVIEW

The engine crankshaft pulley drives the accessory components, which comprise the generator, engine coolant pump and the A/C (air conditioning) compressor.

Accessory Drive - System Operation and Component Description

System Operation

OPERATION

The crankshaft pulley provides the drive for the components located on the accessory drive belt. The belt is automatically pre-loaded by a tensioner and is routed over deflection idler pulleys. The idler pulleys ensure that the belt has maximum contact with the component pulleys in order to maintain sufficient grip between the belt and the component driven pulleys.

This ensures a slip-free drive of the accessory components.

Component Description

DESCRIPTION

The 20 mm belt is designed to achieve fit-for-life performance during normal use. Due to the risk of off-road stone damage, the belt is inspected periodically and, if necessary, replaced. (Refer to the vehicle service schedule for more information). The belt has a rib profile to provide high dimensional accuracy. The surface of the ribs are specially treated to reduce noise.

Engine durability during wading is protected by sealed bearings on the belt idler pulleys and the tensioner. The generator, A/C (air conditioning) compressor and the starter motor are also fully sealed.

Principles of Operation

For a detailed description of the front primary drive belt system, refer to the relevant Description and Operation section of the workshop manual. REFER to: (303-05E)

Inspection and Verification

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.

1. Verify the customer concern.

2. Visually inspect for system integrity and obvious signs of damage.

Visual Inspection

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step

4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart.

Component Tests

Front primary drive belt tensioner

CAUTION: If the engine is run without the drive belt(s) connected to eliminate driven components, diagnostic trouble codes, (DTCs) may be set which must be cleared before the vehicle is returned to the owner. The engine should not be run for more than 2-3 minutes with the belts disconnected. Failure to follow this instruction may result in damage to the vehicle

Static

The only checks required for the front primary drive belt tensioner are for stick, grab or bind.

1. Remove the drive belt in the area of the tensioner.

2. Using the correct tool, rotate the tensioner from its relaxed position through its full stroke and back to the relaxed position to make sure there is no stick, grab or bind, and to make sure that there is tension on the tensioner spring.

3. If the tensioner meets the above criteria, proceed to the dynamic test. If the tensioner does not meet the above criteria install a new tensioner.

Dynamic

The front primary drive belt tensioner can be checked dynamically as follows:

With the engine running, observe drive belt tensioner movement, the front primary drive belt tensioner should move (respond) when the air conditioning clutch cycles (if equipped), the front primary drive belt tensioner should move (respond) when the engine speed is increased rapidly. If the drive belt tensioner movement is erratic without air conditioning clutch cycling or engine acceleration, a pulley or shaft may be bent, or distorted. Excessive drive belt rideout (uneven depth of grooves in the drive belt) can also cause excessive drive belt tensioner movement.

Front primary drive belt

1. With the engine off, check routing of the drive belt.

2. Inspect the drive belt tensioner wear indicator to confirm the drive belt is within operating range. Install a new drive belt as necessary .
