Name: Eagle Tugs Usats Parts and Service Manual (incl. Wiring)
Author: Eagle Tugs

All 158 pages of this Eagle Tugs USATS parts and service manual PDF (OEM #REV17 1.7.16) focus on one thing: keeping your tow tractor and its Yanmar 4TNV98 Tier II and Tier III engines running strong on the tarmac. Inside, you get complete electrical wiring diagrams, full hydraulic schematics, and detailed drivetrain parts breakdowns. Open to the maintenance section for preventative schedules, front end alignment procedures, and page after page of Yanmar diesel torque charts. Lock down the rear Dana 60 axle drive pinion nut to 240-300 lbs-ft, and ensure your emergency tire air pressure is set to exactly 25 PSI before putting the tug back in service. Ground support equipment downtime costs airlines money. Download this bookmarked file right to your tablet, find the exact spec you need, and get the tractor back to work.
