INTRODUCTION

The 980H Wheel Loader has been updated to enhance performance and to meet the Tier III

EPA regulations. The serial number prefix of the 980H Wheel Loader is JMS. The 980H

Wheel Loader retains most of the features of the 980G Series II Wheel Loader. The 980H

Wheel Loader is a direct replacement for the 980G Series II Wheel Loader.

SIMILARITIES AND DIFFERENCES

The two most significant changes to the 980H Wheel Loader are the engine and the power

train. The engine is changing from the Caterpillar 3406E to the Caterpillar C15 ACERT. The

most significant change to the power train is the transmission hydraulic control. The

transmission hydraulic control has changed from the Powershift Transmission control to the

Electronic Clutch Pressure Control (ECPC).

The diagnostic lines group is standard on the 980H Wheel Loader. The diagnostic lines group

is an attachment on the 980G Series II Wheel Loader.

The appearance of the 980H Wheel Loader is changed slightly. Changes to the machine’s

appearance include the hood, the fuel tank, and the battery boxes.

The cooling package is changed on the 980H Wheel Loader. The 980G Series II Wheel Loader

is equipped with the Advanced Modular Cooling System (AMOCS). The 980H Wheel Loader

is equipped with the Next Generation Modular Radiator (NGMR) cores.

OPERATOR'S STATION

The 980H can be equipped with a multi-function joystick instead of two levers. Calibration for

the joystick is similar to the levers. The calibration can be performed with Caterpillar

Electronic Technician (Cat ET) and Caterpillar Monitoring System (CMS).

ENGINE

The 980H Wheel Loader is equipped with the Caterpillar C15 ACERT engine, serial number

prefix LHX. The displacement of the C15 ACERT engine is 15.2 liters with a rated power of

343 hp at 2000 rpm. The performance test specification for the C15 ACERT engine in the

980H Wheel Loader is 0K5301.

The C15 ACERT engine is equipped with a larger muffler (1) and an A4E4 Engine Electronic

Control Module (ECM) (not visible). The fuel manifold (2) is located higher on the engine.
