3406 Thrust Washer 253-1752 Caterpillar Engine Parts | OEM Size

Product Details

Product Overview

This is a high-precision Thrust Washer, OEM part number 253-1752, specifically designed for use in Caterpillar 3406 diesel engines. As a critical component within the engine’s lower end, the thrust washer controls the axial movement (end play) of the crankshaft, preventing contact between the crankshaft and the engine block. This ensures smooth operation and extends the life of the engine bearings and block.

Manufactured by , this component is built to meet or exceed OEM specifications. It is a direct replacement part, commonly used in heavy-duty applications including construction machinery, industrial equipment, agricultural tractors, marine propulsion systems, generator sets, and material handling equipment. Each unit is rigorously inspected and tested to ensure perfect fitment and long-lasting performance in demanding environments.

FAQ

Q1: How do I verify that this thrust washer (253-1752) fits my engine?
A: The 253-1752 thrust washer is specifically designed for the Caterpillar 3406 engine series. To confirm fitment, remove your old thrust washer and check for the part number stamped on it. If it matches 253-1752, this part is a direct replacement. You can also measure the thickness and diameter to compare with the OEM specifications.

Q2: What is the function of a thrust washer in a 3406 engine, and what happens if it fails?
A: The thrust washer controls the end play (forward/backward movement) of the crankshaft. If it wears out or fails, the crankshaft can move excessively, causing the main bearing flanges to wear, the connecting rods to misalign, and potentially damaging the engine block. Symptoms of a failing thrust washer include a knocking noise from the lower engine, abnormal crankshaft end play, and low oil pressure. Replacing it promptly is critical to avoid major engine damage.

Q3: Do you provide any installation instructions or torque specifications?
A: While we do not provide specific installation guides for every engine rebuild, we recommend consulting the official Caterpillar 3406 service manual for exact installation procedures and torque specifications. General installation involves cleaning the mating surfaces, lubricating the washer with clean engine oil, and ensuring it sits flush in the block groove. A Machinery Test Report is provided with the part to confirm its dimensional accuracy.
