Pacific P510 Logging Truck
A Pacific P510 semi-truck hauled logs in New Zealand using twin diesel engines.
Twin Engine Setup
The truck used a 14.6-liter Caterpillar 3406B engine for the tractor and a 14.6-liter Caterpillar 3406A for the trailer.
Power and Performance
The twin engines produced about 900 horsepower to pull multiple trailers in steep terrain.
Engine Details
Both engines had turbochargers, separate transmissions, and CAT’s BrakeSaver tech for braking.
Dust and Air Intakes
The trailer’s air intake was moved to prevent dust from entering the engine.
Engine Challenges
Early issues included dust problems and finding suitable differentials for the heavy load.
Current Status
The truck is being restored by Lance Magee, who may have sold the trailer for scrap.
“Lance told me that the first lot of Meritor Rockwell diffs couldn’t handle the weight...”
