A new Axle Shaft Oil Seal, PN 4137426, was incorporated into all 7-1/4, 8-1/4, and 9-1/4 (standard) axles during April, 1984.
The new seal replaces the old seal, PN 2931875, in all of these applications, and will service prior model year applications. The new seal features a
flange which insures installation to the proper depth, and incorporates a sealant on the outside diameter. These features provide improved sealing.
The new seal can be installed by using existing Miller Special Tool. Use Miller Special Tool #C-4202 and handle #C-4171 to install the seal. Turn Tool
#C-4202 so that the flat side is against the seal. Drive the seal flange flush with the axle housing.
CAUTION:
DO NOT USE SPECIAL SERVICE TOOL #C-4130 CALLED OUT IN THE SERVICE MANUALS, AS THE FLANGE WILL
BE DAMAGED AND AN OIL LEAK MAY RESULT. THE CURRENT SEAL, PN 2931875. WILL CONTINUE TO BE USED
FOR SERVICE UNTIL THE NEW SEAL, PN 4137426, IS AVAILABLE FOR SERVICE.
