3024C 0.25 Main Bearing and Connecting Rod Bearing for Caterpillar Excavator Engine Parts

Product Details

Product Overview

This high-precision engine bearing set is specifically designed for the Caterpillar 3024C diesel engine, a powerplant commonly found in compact construction and industrial equipment. The set includes both main bearings and connecting rod bearings in a 0.25mm oversize (0.25 OS) specification, making it an ideal solution for engine rebuilds where the crankshaft has been ground down to the first undersize.

Manufactured under the brand, these bearings are engineered to meet OEM dimensional and material specifications, ensuring a reliable fit and consistent oil clearance. This kit is commonly used for overhauling Caterpillar 3024C engines in excavators, bulldozers, forklifts, loaders, and other heavy machinery, providing the necessary precision for restoring engine performance and longevity.

Key Features & Benefits

• Precision 0.25mm Oversize: Specifically machined for crankshafts ground to the first undersize (0.25mm), ensuring correct crush height and bearing clearance for a reliable rebuild.
• Complete Bearing Set: Includes both main bearings and connecting rod bearings in one package, simplifying the ordering process and ensuring component compatibility.
• OEM-Grade Material: Constructed from high-strength steel-backed aluminum alloy, providing excellent fatigue resistance and load-bearing capacity for diesel engine applications.
• Enhanced Oil Film Retention: Precision-machined oil grooves and holes ensure optimal lubrication distribution, reducing friction and preventing seizure during high-load operation.
• Stringent Quality Control: Each bearing undergoes dimensional inspection and hardness testing to guarantee consistent wall thickness and crush fit, meeting or exceeding OEM standards.
• Engineered for Durability: Designed to withstand the high compression ratios and thermal stresses of the Caterpillar 3024C diesel engine, extending the service life of the rebuilt engine.

Technical Specifications

OEM Cross-Reference

This bearing set is a direct replacement for the following Caterpillar OEM part numbers. Please verify your original part number before ordering:

• Caterpillar OEM Main Bearing: 8-98023-526-0 (typical reference for 3024C)
• Caterpillar OEM Connecting Rod Bearing: 8-98023-527-0 (typical reference for 3024C)
• Alternative Reference: 3024C Bearing Kit (0.25 OS)

Note: Always cross-reference your existing bearing part numbers with the list above to ensure correct fitment. The 0.25 oversize designation is critical for engines with reground crankshafts.

Compatibility

This bearing set is specifically designed for the Caterpillar 3024C diesel engine. This engine model is commonly used for powering the following types of equipment:

• Excavators: Compact and mini excavators
• Bulldozers: Small to medium dozer models
• Forklifts: Heavy-capacity industrial forklifts
• Loaders: Compact wheel loaders and skid steers
• Trucks & Buses: Light-duty commercial vehicles

Important: This part is specifically for the 3024C engine model. It is not interchangeable with the 3024 (non-C) or other 3000 series engines without verification of bore size and journal dimensions.

FAQ

Q1: How do I confirm that this 0.25mm oversize bearing is correct for my engine rebuild?

The 0.25 oversize bearing is intended for use when the crankshaft journal has been ground down by 0.25mm (0.010 inch) during a rebuild. You must measure the reground journal diameter with a micrometer. If the journal diameter is exactly 0.25mm smaller than the standard specification, this bearing is correct. Always consult your engine service manual for the specific bearing clearance specifications for the 3024C engine.

Q2: Can I install these bearings without specialized tools?

While basic hand tools can be used, we strongly recommend using a bearing installer tool and a torque wrench for proper installation. The main bearing caps and connecting rod caps must be torqued to the exact specifications in the Caterpillar 3024C service manual (typically in the range of 45-55 Nm for main caps, but verify with your manual). Improper torque can lead to bearing spin or seizure. A plastigage check is also recommended to verify oil clearance after installation.

Q3: What is the difference between the main bearing and the connecting rod bearing in this set?

The main bearings are larger and support the crankshaft within the engine block, while the connecting rod bearings are smaller and fit between the connecting rod and the crankshaft journal. Both are included in this set and are specifically sized for the 3024C engine. They are not interchangeable. The main bearings have oil feed holes to supply oil from the block, while the rod bearings rely on oil passages from the crankshaft. Always install each bearing type in its correct location.
