Heavy Equipment Starters & Alternators — 60 NOS Units, Cross-Referenced

SATX Parts & Supply keeps 60 new-old-stock starters and alternators on the shelf in San Antonio, Texas — Delco Remy, Bosch, Denso, Nikko, Hitachi, Prestolite, Mitsubishi and Perkins units in 12V and 24V for construction, mining, agricultural and industrial diesel engines. Every unit is new and unused, and most listings carry verified interchange numbers, so you can find it by whatever number is on your old tag.

New old stock — not rebuilt, not remanufactured

Everything on this page is genuine new old stock: new, unused units from surplus inventory, never installed on a machine. You get factory windings, bearings, brushes and solenoids with zero hours on them — not a reman assembled from a used core. That also means no core charge and no old unit to box up and send back. NOS supply is finite, though: when a part number sells out, it is usually gone for good, so if you see your number below or in the full catalog, it is worth grabbing.

35 starters, 25 alternators

Delco Remy 37MT/40MT/42MT/50MT, Bosch KB/KE/IF, Denso, Nikko, Hitachi, Mitsubishi, Prestolite and Perkins units.

12V and 24V systems

Units for construction, mining, agricultural and industrial diesels — Caterpillar, Cummins, Komatsu, Isuzu, Volvo, Perkins and more.

Specs and real weights listed

Listings include voltage and amperage specs plus actual shipping weights, so freight quotes to your ZIP come out accurate.

One unit, five part numbers — search by any of them

Heavy-equipment electrics collect part numbers. The same 24V Nikko starter can carry a Komatsu number (600-813-3660), a Nikko factory number (0-23000-6510) and a distributor stock number (91-28-4016) — one unit, several labels. We have verified our cross-reference data against industry interchange records covering Delco Remy, Bosch, Denso, Prestolite, Hitachi, Nikko, Caterpillar, Komatsu, Cummins and Perkins numbering, and most listings carry the OEM number alongside the equivalents. The parts catalog search matches cross-reference numbers too — search your Delco, Bosch or Denso number even if you never knew the OEM one.

Running Perkins power? Seven Perkins 2873-series starter motors and four 2871-series alternators are on the shelf alongside our other Perkins inventory — see the Perkins parts page. For off-highway rigid hauler parts, browse the Euclid-Hitachi parts page. And if you have NOS starters or alternators collecting dust in your own parts room, we buy surplus.

How to confirm fit before you buy

Start with voltage: most full-size excavators, dozers, haul trucks and large generator sets run 24V electrical systems, while most skid steers, backhoes and farm tractors are 12V. Then go to the numbers. The ID tag on your old starter or alternator is the surest starting point — send us every number stamped on it, plus your engine make and model, and we will run them through the interchange data before you commit. A phone photo of the tag emailed to sales@satxpartsandsupply.com works fine.

Everything ships from San Antonio, Texas, anywhere in the US. These are heavy units, so listings carry real shipping weights — send your ZIP code and we will quote freight to your door. eBay purchases carry 30-day returns. We also respond to county bids and quote requests, and a W-9 is available on request.

Frequently asked questions

Can I search by my Delco Remy, Bosch, or Denso number?

Yes. Our listings carry the OEM part number plus interchange numbers verified against industry cross-reference records, and the catalog search matches any of them. Type in whatever number is on your old unit's tag — Delco Remy, Bosch, Denso, Prestolite, Nikko, Hitachi, Caterpillar, Komatsu, Cummins, or Perkins — even if you never knew the original OEM number.

Are these starters and alternators new or rebuilt?

They are new old stock (NOS): new, unused units from surplus inventory that were never installed on a machine. They are not rebuilt and not remanufactured, so there is no core charge and no core to return.

How do I confirm the right starter or alternator for my machine?

Send us every number on your old unit's ID tag along with your engine make and model — a photo of the tag works well. We check the numbers against the interchange data and confirm fit before you buy. Call (210) 942-3553 or email sales@satxpartsandsupply.com.

Need the right unit confirmed?

Send the numbers off your old unit's tag and your ZIP code — we'll verify the interchange and quote shipping to your door.
