PROBLEM

Show/hide table

The existing king pins in front axle of certain 24M Motor Graders can cause a squeaking noise when steering due to insufficient lubrication and due to some pins not meeting hardness specification. If the existing noisy king pins are not replaced, they can cause damage to bores and other parts in the joint.

ACTION REQUIRED

Refer to the Service Manual if/as required to rework all four king pin joints by replacing with new parts listed below.
Rework Procedure:
1. Attach the 5T-0504 Washer to the 117-2176 King Pin with preset gap of 2.0+/-0.5 mm using shims or feeler gauge to achieve accurate final gap.
2. Apply grease to highlighted area of the pins only.
3. Freeze the Kingpins with steps 1 & 2 complete. This will ensure proper gap and proper greasing prior to pins assembled into 117-2177 Spindle Housing.

Note: Refer to KENR6022 in SIS for Disassembly and Assembly of Spindle Housing Remove and Install which includes King Pin procedure.
