Failures and CausesFigure 9.4Figure 9.5Lubrication5. Exhausted Additive Damage:Meritor axles requires lubricants that meetthe specifications EP (Extreme Pressure) withadditives’ base of sulfur / phosphorus. To function,the required oil is GL-5, as specified L--PRF-2105E. Inappropriate grade lubricantwith additives depleted or in situations of lowoil level (or no oil) can take the ring gear anddrive pinion to provide a lubrication failure characterizedby contact wear pattern, which isknown as “crow’s foot”. Such patterns are describedas lines or grooves in the teeth of thegear. Figure 9.5. and Figure 9.6.Meritor transmissions require that the lubricantsare for heavy-duty engine (straight grade)or GL-1 petroleum with corrosion and oxidationinhibitor (mineral or synthetic).Lubricants for tractive axles MUST NOT beused in transmissions, as well as lubricants fortransmissions MUST NOT be used in tractiveaxes. The mixture of the two lubricants acceleratesdeterioration and premature wear ofparts in the assembly. For more informationsee the lubrication Maintenance Manual No. 1,Lubrication.Figure 9.6MAINTENANCE MANUAL43
