Cummins 12v turbo diesel joins the fleet – April 2021

Welcome to the Fleet

1997 Dodge Ram 2500 4×4 5.9L Cummins 12 valve turbo diesel, extended (club) cab long bed, 47RE 4spd automatic transmission, ball joint Dana 60 front axle, NP241 t-case, Dana 70 rear axle 3.55 gears.

Drove it home the 450 miles from Death Valley, where it has spent at least the past 10 years as a work truck on a desert resort property, hauling heavy trailers and campers. Needs some TLC and a thorough mechanical baseline.

Started with a basic oil change, using a blend of 10 quarts of 15W-40 Motorcraft and 1 quart of 5W-40 Rotella T6, and a WIX oil filter. Interesting to note that a 12 valve Cummins only takes 11 quarts of oil, compared to the 7.3L Powerstroke that requires 15.

Next up, WIX fuel filter and learning to prime the P-pump fuel system using the air plunger. Unknown fuel filter was in the truck, and am taking precautions to treat algae and microbes in the fuel system.

On to the chassis, replaced front unit bearing hubs with MOOG units. All new front slotted and vented front disc rotors and pads. For the rear, new rear axle seals and Timken hub bearings, 80W-90 gear oil and limited slip friction modifier in the rear differential, all new brake shoes, wheel cylinders, and drum brake hardware.
