( 2 ) For New Systems, Refilled Systems, and Converted Systems
( 3 ) Level 1 Sample
( 4 ) Level 2 Sample
( 5 ) There are three sets of differential/final drives.Sampling Locations
For systems equipped with a sampling valve, take sample with engine running at low idle. For systems without a sampling valve, take sample with engine stopped. Take ALL samples with transmission in neutral, parking brake applied, dump body lowered (except when the body support is installed), and steering frame lock Installed.Wipe the area around the sampling valve or the plug before taking a sample in order to prevent contamination. Use a clean sampling gun when accessing an oil sample through a plug opening. Clean and inspect the plug after obtaining an oil sample through a plug opening.Cooling System Coolant Sample (Level 1 and 2)
