Draining
Eaton Fuller has a complete listing of approved lubricants for its transmissions on its internet website. Refer to the Eaton website for additional information, www.roadranger.com .
Important: Manual transmissions filled with approved synthetic lubricants require a lubricant drain and fill, and a magnetic plug cleaning every 500,000 miles (800 000 km), regardless of the service or vocation of the vehicle. Manual transmissions with petroleum-based lubricants require a lubricant drain and fill, and a magnetic plug cleaning at each Maintenance 2 (M2) interval. All transmissions, regardless of lubrication used, also require a check of the transmission breather at each Maintenance 1 (M1) interval.
- Park the vehicle on a level surface. Apply the parking brakes and chock the rear tires.
- Drain the fluid while the transmission is warm, as follows.
- Clean the magnetic plug(s) before installing it. Use a piece of key stock, or any other convenient steel slug, to short the two magnetic poles and divert the magnetic field.
- Install and tighten the drain plug(s) 50 lbf·ft (68 N·m).
