International Harvester 500 Crawler Tractor: The Foundational Vintage IH Compact Crawler
The IH 500 sits at the entry point of the International Harvester crawler tractor lineage - a compact, multi-purpose track machine built for agriculture, light construction, and utility work. As the predecessor to the 500E, it established the mechanical service architecture that carried forward through the early Dresser-era machines.
Where the 500 fits in the IH / Dresser line
The IH 500 is the foundational vintage IH crawler tractor - a compact multi-purpose machine that established the platform later refined into the 500C and 500E. Designed for agriculture, light construction, and utility work, the 500 runs an IH diesel through a mechanical drivetrain into a tracked undercarriage with direct-acting hydraulic blade controls.
Production saw multiple revisions across the IH-era run, so serial-number verification is critical for ordering year-specific components. The 500 platform shares many service items with the later 500C and 500E - brake bands, steering discs, and certain hydraulic components cross-fit across the series.

Engine, hydraulics, and drivetrain
The IH 500 runs an IH diesel through a mechanical drivetrain into a tracked undercarriage. The hydraulic system uses direct-acting blade controls fed by a main pump that cross-fits across IH / Dresser dozers. Steering is by clutch-and-brake band on either side - a service-friendly architecture that responds well to standard wear-item replacement.
The engine, brake, and steering components are well-supported by the IH and Dresser parts ecosystem. Cross-fit head gaskets, water pumps, and hydraulic pumps are available, and the brake band / steering disc package is direct-fit on the 500C and 500E as well.
Common service items on the 500
- Engine internals: IH 500 series diesel - pistons, rings, sleeves, head gaskets. The S.57678 head gasket set cross-fits.
- Cooling system: 3132738R93 water pump fits IH / Dresser dozers.
- Steering brakes: 500C/500E direct-fit brake band 676915R92, steel steering disc 676833R1, fiber steering disc 675848R2 (IH 500 fiber).
- Hydraulic system: 623084C92 main hydraulic pump cross-fits Dresser dozers. Blade hydraulic service.
- Operator station: PV862 seat package fits IH / Dresser dozers and loaders.
- Blade: Blade cutting edges, mounting hardware (5J4773 cutting edge bolt), pivot pins.
- Electrical: Starter, alternator, gauges, switches.
- Undercarriage: Track chains, rollers, idlers, sprockets.

Need a part for your IH 500 Crawler Tractor?
Brake bands, steering discs, head gaskets, and hydraulic pumps are the highest-demand items on the 500 platform. Call our parts team with your serial number and we’ll match the right component to your machine.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the 500 before ordering year-specific parts.
- Engine serial. Internal engine parts must match the engine serial number.
- Generation. IH-era and Dresser-era machines saw multiple revisions - confirm by serial.
- Undercarriage spec. Track shoe count, roller and idler configuration vary by build - measure before ordering.
- Steering disc material. Fiber vs. steel steering discs differ by 500 vs. 500C/500E - verify against the existing components before ordering.
- Brake band fit. The 676915R92 brake band is direct-fit on 500C/500E; confirm fitment on early IH 500 builds.
Why the 500 still earns a paycheck
The IH 500 is a vintage compact IH crawler tractor - agriculture, light construction, utility work. Its mechanical service architecture and the broad IH / Dresser parts ecosystem mean these machines remain serviceable decades after their production run. Cross-fit head gaskets, water pumps, and hydraulic pumps keep the engine and hydraulic side supportable, while the 500C/500E brake band and steering disc parts cover the steering-and-brake service needs.
Maintenance priorities on a 500: clean fuel, IH diesel head gasket service (S.57678 cross-fit), brake band and steering disc service (676915R92 / 676833R1 / 675848R2 specifically fit 500-series), undercarriage replacement on schedule, and routine hydraulic filtration. Broken Tractor maintains parts coverage for the IH 500 alongside the broader IH / Dresser machine family.
