Part Number Identification
All Meritor differential assembly part numbers comprise of three sections:
A3 -
e.g.
Prefix
The prefix number changes from application to application and defines the variable features such as drive coupling type, differential locks etc.
The base number is the same for all differentials assembled within a particular axle range. All Meritor differential Base numbers start with the
numbers "3200"
The ratio is given as a 3 digit number directly after the differential part number.
A3 3200Q2123-308
Example:
This would signify that the axle ratio is 3.08:1
Nominal Axle Load Rating
(GAWR):
In thousands of pounds.
Individual forwards and rear
axle of a tandem set (D, N, P,
R) are rated as single axles.
A tandem set (T) is rated as
the combination of the two
axles and a tridem set (Z) as
the combination of the three
axles.
