Repower Profile: Jeep UACJ-6D

Cummins powered Jeep UACJ-6D on sand dunes

“One of the easiest installs you’ll ever do,” said Christian Hazel, editor of Petersen’s 4 Wheel & Off-Road Magazine about repowering the 1971 UAJ-6D.

Once everything was in place, the Cummins R2.8 fired up on the first try and has been cruising down the road ever since. In fact, anyone curious about what it takes to install a R2.8 Turbo Diesel can check out the installation guide on our Repower page.

cummins r28 repowered Jeep UACJ-6D dirt roadThis patina'd Jeep has been everywhere from off-roading during Ultimate Adventure 2017 to the floor at the SEMA Show. During its numerous adventures, it has consistently averaged 22-23 mpg at highway speeds, which is especially impressive considering the beadlocks and 38-inch mud tires. Throughout its travels, this UACJ-6D has also been a beta vehicle for the R2.8 Turbo Diesel program. As a beta vehicle for the program, it has been subjected to harsh conditions that range from high altitude to high temperatures to ensure that Cummins delivers the best quality product to customers.

Los Custompaks de Cummins se utilizan para la gestión del agua mientras Tailandia lucha con su crisis de agua

CustomPak in situ

Water crisis

Sixty Cummins Inc. CustomPaks are in service in Thailand as part of a critical water management plan aimed at easing the country’s water crisis – a crisis that has caused enormous economic and social damage and stirred conflict among communities.

En las últimas décadas, Tailandia ha enfrentado continuamente problemas de agua causados por una grave sequía. Water reserves in dams and reservoirs are insufficient while water resources are often contaminated with toxins caused by urban communities and the industrial and agricultural sectors.

Severe flooding is a threat, too, at a time when the realities of climate change are hanging over the country.

As a result, the allocation of precious water resources, which must be shared among various stakeholders including new and existing industry, large and small agriculture, and cities and villages has become a flashpoint.

Kittithanapat Engineering Co. (KTP), has been involved in the water management system since 1996, working closely with authorities such as the Royal Irrigation Department, Department of Water Resources, Bangkok Metropolitan Authority and others.

CustomPaks on site

600 hp CustomPaks

To help KTP meet its often urgent requirements, Cummins DKSH (Thailand) has recently supplied 60 Australian-built CustomPaks - 45 powered by Cummins' X15 engine rated at 600 hp, and 15 powered by the QSL9 rated at 325 hp. These fully self-contained powerpacks are emissions certified to Tier 3.

The CustomPaks are coupled to hydraulically-driven, large-volume submersible water pumps sourced by KTP from US company Moving Water Industries (MWI); KTP is the exclusive distributor in Thailand for these MWI Hydroflo pumps.

Prior to Cummins’ involvement, KTP was using another diesel engine brand but service support wasn’t up to the standard required.

Long-serving KTP engineer Kittisak Thanasoot says Cummins DKSH’s reputation for technical and aftersales support along with the reliability of the Cummins product were a key reason behind KTP’s decision to specify the CustomPaks for the Royal Irrigation Department.

The ability of Cummins DKSH to respond to short delivery times was also important.

“Supplying large quantities of high horsepower diesel engines for emergency situations such as flash flooding can be a challenge for KTP,” says Kittisak Thanasoot.

“Responding to the needs of the government agencies to manage such problems in a timely manner and with least impact on communities, KTP has found the answer in our partnership with Cummins DKSH.”
