About Connecting rod

Replacement Engine Connecting Rods for Diesel Engines

Find replacement engine connecting rods for selected heavy equipment, excavators, tractors, forklifts, industrial engines, and trucks at FAB Heavy Parts. This collection includes connecting rods for applications from brands such as Kubota, Yanmar, Isuzu, Mitsubishi, Caterpillar, Cummins, and Hino. Use the listed part numbers and engine applications to narrow your search for the replacement component needed for your repair or engine rebuild.

A connecting rod links the piston to the crankshaft and transfers force from the piston to the rotating crankshaft. Because it operates under repeated mechanical loads inside the engine, the correct dimensions, bearing interfaces, and fitment are essential when replacing a worn or damaged rod.

Connecting Rods for Different Engine Applications

The collection includes individual connecting rods and connecting rod assemblies for a range of engine families. Examples include connecting rod 1G772-22013 for specified Kubota V3307 applications, part number 8943996112 for listed Isuzu 4HK1 and 4HE1 applications, and connecting rods for selected Yanmar and Mitsubishi engines. These examples represent specific product listings; compatibility should not be inferred for other engines simply because they share a brand name or similar model designation.

Product titles and descriptions may include part numbers, engine models, and supported equipment applications. Compare these details carefully when selecting a replacement, particularly when several versions of an engine or equipment model exist.

How to Choose the Correct Connecting Rod

Start with the part number from the original connecting rod or the engine parts documentation. Confirm the exact engine model and, where relevant, its serial number or specification. Check the product listing for the stated application and whether the item is sold as a single rod, a specified quantity, or an assembly.

During an engine rebuild, inspect related components such as the crankshaft and connecting rod bearings. A connecting rod replacement does not automatically resolve damage to the crankshaft, bearing surfaces, piston, or other internal components. Follow the engine manufacturer's inspection limits and assembly procedures.

Frequently Asked Questions

How do I find the correct connecting rod for my engine?

Please start with the part number from your original connecting rod or your engine parts catalog. Compare it with the part number and engine application listed on the product page. Please also confirm the exact engine model and any relevant serial number or specification. Similar engine names do not necessarily mean that the connecting rods are interchangeable.

Are connecting rods for different versions of the same engine interchangeable?

Not always. Different engine versions can require different connecting rod designs or dimensions, even when their model names are similar. Please compare the replacement part number and the specific engine application before ordering. If you are unsure, send us your engine model, serial number if available, and original part number so we can review the information with you.

Does the connecting rod listing include a complete set or just one rod?

The quantity depends on the individual connecting rod. Some product titles specify one connecting rod, while others may describe a different quantity or configuration. Please review the product title, description, and selected options carefully before checkout so you know what is included in your order.

Should I replace the connecting rod bearings when installing a new connecting rod?

Please have the connecting rod bearings and crankshaft journals inspected as part of the repair. Whether the bearings need replacement depends on their condition, measured clearances, and the engine manufacturer's service specifications. Replacing a connecting rod alone does not correct damage to other internal engine components.

What information should I provide if I cannot find the connecting rod for my engine?

Please share the engine manufacturer, exact engine model, serial number if available, and the part number from your original connecting rod or parts catalog. A clear photo of the original component and any identifying markings may also help. You can submit your requirements through our Request a Quote page, and we can review the available information with you.
