SATX Parts & Supply holds one of the larger surpluses of Euclid E-series part numbers still available — new-old-stock components for the rigid haulers Euclid built before and during the Hitachi era. Verified Hitachi cross-references, fitment checked against your serial number, shipped nationwide from San Antonio, Texas.
The classic Euclid rigid haulers. Steering pumps and valves, wheel seals, A/C mounting kits, and a deep shelf of smaller E-numbers.
Hitachi-era trucks that carried the Euclid designs forward. Brake caliper seal kits, rear wheel seals, filters, and electrical parts.
Large-frame haulers. Hoist controllers and control levers, wire harnesses, sensors, and pressure switches.
Some numbers reach beyond the trucks — hydraulic motor 4439383 fits EX1800, EX1900, and EX3600 excavators.
These trucks were cataloged under Euclid E-prefix part numbers, and decades later that is exactly what makes parts hard to source: the number stamped in your parts book may not match the number a dealer's screen recognizes. Our listings show both — the original Euclid E-number and the verified Hitachi-era cross where one exists — so whichever book you are working from, you can find the part. Steering pump E12585087 for the Euclid R85 and hoist controller E12636648 for the R90C / EH4500 / EH5000 are good examples of numbers that rarely surface anywhere else.
Everything ships from our warehouse in San Antonio, Texas. Freight is quoted by location — send your ZIP code — and eBay purchases carry 30-day returns. We respond to county bids and quote requests, and a W-9 is available on request.
This is the most expensive mistake we see Euclid buyers make. Terex TA-series articulated trucks (the TA30 and its siblings) are not Euclid lineage — the designs split in 1968 and never reconverged. Euclid E-series part numbers and TA-series 15xxxxxx numbers never interchange, even when the components look alike in photos. If your machine is a TA-series, source against Terex numbers instead.
A sample of what is on the shelf right now — roughly a third of our listed Euclid-Hitachi stock. For the rest, browse the full parts catalog or our eBay store.

Cross numbers come straight from our shelf tags and listing data. Always confirm fitment with your machine serial number before ordering — we will check it for you.
The table above is only what has made it online. Beyond the live listings we have dozens of unidentified and structural E-series parts on the shelf — brackets, weldments, tubes, pins, latches, and hardware that may never get individual listings. If you are chasing an E-number you cannot find anywhere else, email sales@satxpartsandsupply.com or call (210) 942-3553 with the part number and your machine serial number, and we will check the shelf and verify fitment before you commit.
Two related pages worth a look: we also stock Hitachi and Nikko starters and alternators used across Hitachi- and Isuzu-powered equipment, and if you are retiring a Euclid or Hitachi hauler with a parts room left over, we buy surplus inventory.
No. Terex TA-series articulated trucks are a separate design lineage that split off in 1968, long before the Euclid-Hitachi era. E-prefix part numbers and TA-series 15xxxxxx part numbers never interchange, even when components look similar. If you run a TA30 or any TA-series truck, source against Terex numbers instead.
Send us your machine serial number along with the part number you need. We verify both against cross-reference data before you buy, so you are not guessing from a worn tag or a casting number.
Yes. Dozens of E-series components and structural parts are on our shelves but not yet listed online. Email or call with the part number, plus your machine serial number if you have it, and we will check the shelf.
Send the part number and your machine serial number — we will confirm fitment and quote freight to your ZIP.
