• Change the lubricant filter every 120,000 miles
(192,000 km). Top off the lubricant level with a similar
lubricant.
Eaton/Dana Axle Lubrication
• The original mineral-based lubricant must be drained
within 3000-5000 miles (4800-8000 km) on all Eaton
axles. This initial change is very important because it
flushes out break-in contaminants that might otherwise
cause premature wear.
• No initial drain is required on Eaton axles that are factory
filled with an Eaton-approved synthetic lubricant.
• Mineral-based lubes must be drained within the first
5000 miles (8000 km) if converting to an Eaton-approved
synthetic lube.
• Change the lubricant within the first 5000 miles (8000
km) of operation after a carrier head replacement, regardless
of the lubricant type.
• Refer to the Eaton Field Maintenance Manual for a
particular axle for lubricant specifications.
• See your Peterbilt dealer for Eaton-approved lubricant
brands.
• Refer to the chart below for lubricant change interval.
