Replacement Starter Motors for Heavy Equipment and Diesel Engines

Find replacement starter motors for selected excavators, loaders, tractors, industrial diesel engines, forklifts, and other equipment. FAB Heavy Parts offers starter motors and starter assemblies for applications from manufacturers such as Kubota, Yanmar, Perkins, Isuzu, Komatsu, Takeuchi, and CASE. Use the listed part numbers and equipment applications to narrow your search.

Starter Motors for Different Engine Applications

This collection includes a variety of starter configurations for different machines and engines. Examples include starter motor 129136-77011 / 129400-77012 for selected Yanmar-powered Komatsu PC35, PC40, and PC50 excavators; Kubota starter motor 19269-63013 for selected D902, D950, and D722E applications; and Perkins starter 2873006T for selected industrial engines.

Product specifications vary by application. Listings may identify the operating voltage, starter pinion tooth count, power rating, engine model, or replacement reference numbers. Some products are starter assemblies or starter-generators rather than conventional starter motors, so review the exact product description before choosing a part.

How to Choose the Correct Starter Motor

Start by matching the number on your existing starter with the replacement part number or cross-reference listed on the product page. Confirm the engine model and equipment application, then compare the electrical and mechanical specifications provided. These may include 12V or 24V operation, pinion tooth count, power rating, mounting arrangement, and terminal configuration.

A starter motor that looks similar may still have different mounting dimensions, gear engagement, or electrical requirements. Do not assume that parts are interchangeable simply because they share an engine family or equipment brand.

If your machine has a starting problem, check the battery condition, cable connections, starter control circuit, and related components before concluding that the starter motor has failed.

Frequently Asked Questions

How do I find the right starter motor for my excavator or tractor?

Please start with the part number on your original starter motor, then compare it with the replacement part number and the engine or machine applications listed on the product page. If you need help narrowing down the options, please share your equipment make, model, engine model, and existing starter part number with us.

Does a 12V starter motor fit every machine with a 12V electrical system?

No. Voltage is only one part of the match. Please also compare the listed engine application, part number, pinion tooth count, mounting arrangement, and electrical connections. Two starters with the same voltage may still be different designs.

What does the tooth count on a starter motor mean?

The tooth count refers to the teeth on the starter motor’s pinion gear, which engages with the engine’s ring gear during starting. Please compare the tooth count and the specified part number with your existing unit or equipment parts information rather than choosing by voltage alone.

My engine will not crank. Do I need to replace the starter motor?

Not necessarily. A weak battery, loose or corroded battery cables, a poor ground, or a problem in the starter control circuit can also prevent cranking. Please check these possible causes before ordering a replacement. If the starter has been confirmed faulty, use the engine and part details to find a suitable replacement.

What information should I provide if I’m unsure which starter motor to order?

Please provide the equipment make and model, engine model, original starter part number, system voltage, and a clear photo of the existing starter’s label and mounting connections if available. These details can help us narrow down the relevant starter motors, although any final match should be supported by the product’s specifications and application information.
