FILTER AS 9Y4407 - Caterpillar

ACTION REQUIRED
Refer to the Service Manual if/as necessary. Replace the universal joint per KENR8397.
Install the tie rod assembly and plates per Special Instructions SEHS0006 "Procedure to Install a Rear Axle Tie Rod Stiffener to the 793F Off-Highway Truck". The tie rod assembly will connect the rear axle and transmission.
This will create a stiffer drivetrain that will be less susceptible to vibration issue, which will extend u-joint service life.
Perform a visual inspection for cracks on the welded joint near the transmission case flange. A crack can possibly form in the weld between the gussets on the right and left side of the transmission case. Please see diagrams below. Clean the area and inspect for visible cracks or signs of oil leakage. If a crack is found, please work through your Dealer Technical Communicator to submit this information to the DSN (Dealer Solution Network) for information necessary to complete any repairs prior to proceeding.
