Cat® Large Wheel Loaders are designed with durability built in, ensuring maximum availability through multiple life cycles. With optimized performance and simplified serviceability, our machines allow you to move more material efficiently and safely at a lower cost per ton. Introduced in 1963, the 988 has been the industry leader for over 50 years, built on a legacy of reliability, performance, safety, operator comfort, serviceability, and productivity. The 988K XE brings improved sustainability and maximum efficiency to this machine platform.
All nonroad Tier 4 Final/Stage V diesel engines are required to use: – The machine has the flexibility to run on either ultra-low-sulfur diesel fuel (ULSD with 15 ppm of sulfur or less). – Cat engines are compatible with the following renewable, alternative, and biodiesel* fuels that reduce greenhouse gases: Up to B20 biodiesel (FAME) ** Up to 100% HVO and GTL renewable fuels * Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details. – Cat DEO-ULS™ or oils that meet the Cat ECF-3, API CJ-4, and ACEA E9 specifications are required. – Only use DEF that meets ISO 22241-1 standards.

Note (1)
The operator sound pressure level was measured according to the test procedures and conditions specified in ISO 6396:2008. The measurement was conducted at 70 percent of the maximum engine cooling fan speed.
Note (2)
Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors or windows are open for extended periods or in a noisy environment.
Note (3)
The machine sound power level was measured according to the test procedures and conditions specified in ISO 6395:2008. The measurement was conducted at 70 percent of the maximum engine cooling fan speed.
Air Conditioning
The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 1.8 kg of refrigerant which has a CO2 equivalent of 2.574 metric tonnes.
