BELT TENSIONERS

John Deere engines use two types of belt tensioners: manual and automatic. Adjust the belt using the manual

tensioner according to the manufacturer’s specifications. The automatic tensioner cannot be adjusted or repaired

and is designed to maintain proper tension over the belt’s life. Units with the automatic belt tensioner must be inspected

according to the manufacturer’s specifications.

EXHAUST FILTER SERVICE REQUIREMENTS

The exhaust filter system contains a Diesel Particulate Filter (DPF). Over time, the DPF will require professional

servicing to remove ash buildup. The expected service interval will be at least 3,000 or 4,500 hours, based on engine

power and operating conditions. Actual service should take place when the indicator light appears on the Power

Zone™ controller. The DPF should be cleaned or replaced by an authorized service provider only. The removal of

DPF ash must be done by removing the DPF from the unit and placing it into specialized equipment.

CAUTION

Do not remove ash by using water or other chemicals. Removing ash by these methods

may cause equipment damage and create unsafe operating conditions.

CAUTION

Only a qualified service provider should remove, handle and dispose of DPF ash. These

materials may be considered hazardous under federal, state and local regulations, and must

be handled and disposed of properly.

To avoid unnecessary buildup of diesel particulates or soot in the exhaust filter system:

1. Utilize the Automatic Exhaust Filter Cleaning mode.

2. Avoid unnecessary idling.

3. Use proper engine oil. Refer to the engine operator’s manual.

4. Use only ultra low sulfur diesel fuel. Refer to the engine operator’s manual.

ECU OVERRIDE SWITCH

The ECU override switch is located inside the control box. This toggle switch powers

up the ECU without having to start the engine. Use the ECU override switch to turn

the ECU off. If the unit needs to be shut down immediately, use the emergency stop

switch. Refer to “Emergency Stop Switch” on page 31 for additional information.

DO NOT start the engine with the ECU override switch on.

Doing so will damage the ECU.

CHECKING GENERATOR DRIVE PLATE TORQUE

Follow the procedure below to check the torque of the generator drive plate bolts in accordance with the maintenance

chart. Refer to “Basic Maintenance Schedule - John Deere Engine” on page 41.

1. Disconnect the engine starting battery.

2. Remove the generator fan guard.

3. Torque each of the drive plate bolts to the appropriate specification shown in the table below.
