Certified Used CATERPILLAR Starters: 12V and 24V

Our 12V and 24V starters undergo rigorous technical validation before sale. Each unit is performance-tested on a bench to verify its ability to deliver the power required for starting.

The high-quality internal components are thoroughly inspected: solenoid, armature, brushes, and commutator. This methodical approach allows us to certify that each starter will withstand the extreme conditions encountered on your sites.

Whether your CAT engine requires a 12-volt supply for light applications or 24 volts for heavy machinery, our parts ensure fast starts even in cold weather. The reliability of our used starters is backed by a warranty reflecting our confidence in their excellent working condition.

Applications for 302.5 Mini Excavator, Forklift, and Relay

302.5 mini excavators require compact yet powerful starters, typically 12V with a power range of 2.5 to 4.2 kW. These compact machines benefit from instant starts due to low engine inertia. In confined urban sites, this responsiveness is a major productivity asset.

CATERPILLAR forklifts integrate 12V starters with 10 teeth, specially sized for their industrial engines. These applications demand frequent starts in logistics environments where every second counts. The starter relay plays a key role in this chain: it protects the electrical circuit from overloads and ensures optimal current transmission to the solenoid.

This synergy between starter and relay guarantees increased longevity of electrical components, especially appreciated on continuously used equipment.

• The 3116 engine mainly powers 320B excavators, 950G loaders, and D6M bulldozers.
• High-resistance starter designed to endure repeated starts in dusty environments.
• Broad range covering the latest generation C-ACERT engines and classic 3000 series.
• Enhanced starting torque for CATERPILLAR high-compression diesel engines.
• Easy installation thanks to standardized mounting on the engine timing cover.
• Proven compatibility with ADEM and ECM electronic systems of recent machines.
• Durability tested over more than 10,000 start cycles under industrial conditions.

How to Tell if a Caterpillar Starter is Faulty?

Several warning signs indicate starter failure. A metallic clicking noise during start often signals a faulty solenoid or worn brushes. An engine that won’t start despite a charged battery is also a reliable indicator.

Test your starter directly by connecting it to the battery outside the vehicle. If it does not turn or produces excessive sparks, replacement is necessary. Slow or irregular rotation usually reveals an armature or commutator issue.

Also check electrical connections: corroded terminals or damaged cables can mimic starter failure. On CATERPILLAR machines, verify the starter relay, which can cause intermittent issues, especially after long periods of inactivity on site.
