FAQs

Match by machine OEM (Kubota, Case, Deutz-Fahr, Bobcat, etc.), model, and year range — these narrow it down to the specific starter motor variant. Confirm voltage (12V or 24V), power rating (kW), and rotation direction (clockwise or anti-clockwise) against the original. The OEM part number stamped on the failed unit gives the fastest match. If the OEM number isn't available, WhatsApp 07754288583 with the equipment make, model, year, and photograph of the original and we will cross-reference.

Both are valid choices. New units carry full manufacturer warranty and are typically the best fit for fleet-critical and warranty-period vehicles where downtime risk is highest. Remanufactured units rebuild a clean core (housing, cleaned-and-tested armature) with new brushes, bearings, regulator, and field windings — typically 30-50% cheaper than new, with shorter (but still comprehensive) warranty terms. For older plant and agricultural equipment, where original-part-number new units are scarce or expensive, remanufactured is often the only practical option. Each product page lists whether the unit is new or remanufactured and the warranty terms that apply.

Engine cranks slowly or won't crank at all = starter motor or battery problem. Engine starts and runs but the dashboard battery warning light is on, or the battery goes flat between starts = alternator or charging-circuit problem. A loadable battery test isolates the battery; an output-voltage test (engine running, voltage across the battery should read 13.8-14.4V on a 12V system, 27.6-28.8V on a 24V system) confirms whether the alternator is charging.

Both are rebuildable — replacement brushes, bushings, drive pinions, and bearings are available for the majority of common units. For workshop-and-field work, fitting a new or remanufactured unit is faster and reliability-wise better than rebuilding an old unit with field tooling. Rebuild kits are available where the original unit is hard to source new (older Kubota, Case, and specialist plant units). The replacement option is normally listed on each unit's product page.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and 'Check where we deliver' confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa. Use the country selector at checkout to confirm coverage and delivery options for your destination.

Starter Motor & Alternator

Starter Motor & Alternator covers the replacement and aftermarket starter motors and alternators fitted to plant equipment, agricultural tractors, telehandlers, dumpers, and the wider off-highway and heavy-vehicle aftermarket. Parts For Machines supplies trade-grade starter motors and alternators organised by machine OEM — buyers find their replacement by matching the equipment make and model. Within Starter Motor & Alternator you will find Starter Motor (the highest-volume sub-section, organised by machine OEM — Kubota, Case, Deutz-Fahr, Allis Chalmers, Bobcat, and the wider plant and agricultural OEM range), Other Starter Motor (cross-reference fitments), Alternator (similarly organised by machine OEM — Kubota Alternator, Case Alternator, Deutz-Fahr Alternator, etc.), and Other Alternator. Product pages list the application (the specific machine make, model, and year range the unit fits), voltage (12V or 24V — match to the equipment's electrical system), power rating (kW for starter motors; output current for alternators, typically 35A-200A depending on machine size), rotation direction (clockwise or anti-clockwise — must match the original), terminal positions, and where applicable the OEM cross-reference part number. For replacement of an existing starter motor or alternator, the fastest path is matching by machine OEM and the original part number — most plant and tractor manufacturers stamp the part number on the original unit, and the equipment service manual lists it. If the OEM number isn't available, match by equipment make, model, and year, and confirm voltage, rotation, and terminal positions against the original. Plant operators replace starter motors and alternators after start-failure, charging-system failure, or scheduled overhaul — the units are normally rebuildable, but fitting a new replacement unit is faster and cheaper than rebuild for most workshop and field operations. Trade pricing on bulk and fleet orders is available; contact the team via WhatsApp 07754288583 for a quote on volume requirements.
