131-3736 Tie Rod Socket for Cat Motor Graders

The 131-3736 tie rod socket is an aftermarket replacement component for selected Cat motor grader steering systems. Caterpillar identifies reference part number 131-3736 as a 1-14-2A tie rod socket used with the steering cylinder and steering linkage.

The socket connects with the rod ends of the steering control arms and provides a secure, articulated connection within the steering system. During operation, this component is exposed to steering torque, repeated direction changes, vibration and impact loads. Accurate dimensions, correct thread geometry and dependable material quality are therefore important for proper installation and steering performance.

Published reference dimensions are 8.3 inches in overall length, 5.25 inches in overall width and 2.6 inches in overall height. The reference material is carbon steel, and the component incorporates external shaft threads.

The 131-3736 socket is associated primarily with selected Cat 12, 120, 135, 140, 143, 160 and 163 motor grader models. Because equipment configuration and serial-number breaks may affect compatibility, the machine model, serial number and original part number should be checked before ordering.

This product is supplied as an aftermarket replacement. Caterpillar, Cat, machine model designations and part numbers are used for identification and compatibility reference only.
