PROBLEM

Show/hide table

Certain 120M Motor Graders were manufactured with a 295-2585 Breather built into the all-wheel drive spindles. Reference Image 1. These motor graders are to have a 1705123/">170-5123 No Leak Plug installed that will allow the front spindles to be submersed without causing a failure.

NOTE: To implement this letter, a failure mode is having a breather installed verses a no leak plug. Need to replace the breather with a no leak plug to allow for front axle submersion.
