Hazard Alert Messages

Read and observe all hazard alert messages in this publication. 

 WARNING

To prevent eye injury, always wear eye protection when performing 
vehicle maintenance or service.

For complete lubrication information for Meritor’s transfer cases, 
refer to Maintenance Manual MM-1, Preventive Maintenance and 
Lubrication. To obtain a copy of this publication or access it on 
Meritor’s website, refer to the Service Notes page on the inside

Lubricant Temperatures

Meritor MTC-4208, MTC-4210, and MTC-4213 Series 
Transfer Cases

 CAUTION

Meritor MTC-4208, MTC-4210, and MTC-4213 Series transfer 
cases may operate with an oil temperature above 250°F (121°C). 
However, if the oil temperature reaches 300°F (149°C), stop the 
vehicle immediately. Check for the cause of overheating to 
prevent damage to components.

Meritor Transfer Cases can operate with an oil temperature above 
250°F (121°C). However, if the oil temperature reaches 300°F 
(149°C), stop the vehicle immediately. Check for the cause of 
overheating to prevent damage to components.

Do Not Install API GL-5 Oils

 CAUTION

Meritor does not approve petroleum-based and multi-viscosity oil. 
NEVER install API GL-5 oils, which contain extreme-pressure (EP) 
additives. These additives can form sludge at normal operating 
temperatures. Damage to components can result. Use only SAE 
Grade full-synthetic 40W or 50W oil, Meritor specification O-81, 
in the transfer case.

NEVER install API GL-5 oils in a transfer case. This specification 
contains extreme pressure (EP) additives that can form sludge 
at normal operating temperatures and damage transfer case 
components.

Petroleum-Base and Multi-Viscosity Oils

Meritor does not approve the use of petroleum-base and multi-
viscosity motor oils. Refer to Maintenance Manual MM-1, 
Preventive Maintenance and Lubrication.

Meritor does approve the use of synthetic-base oils.

Operating Information

Magnets and Magnetic Drain Plugs

Most Meritor transfer cases are equipped with magnetic drain 
plugs with a minimum pick-up capacity of 20 ounces (0.57 kg) of 
low carbon steel. Reinstall the magnetic drain plug each time the 
oil is changed. Use the correct part. If a pipe plug is used instead of 
a drain plug, the pipe plug will leak.

Drain plugs can be reused if it has a minimum pick-up capacity of 
20 ounces (0.57 kg) of low carbon steel after it has been cleaned.
