IH-Dresser 175 Crawler Loader: Heavy-Duty Tracked Loader for Mining, Quarry & Demolition

The IH-Dresser 175 is the heavy crawler loader sitting between the 125-series and the largest IH-Dresser loaders. Built for mining, quarry, demolition, and industrial loadout, the 175 is the predecessor to the later Dresser 175C and remains a workhorse where bigger bucket and breakout are needed.

Where the 175 fits in the IH / Dresser line

The IH-Dresser 175 is the heavy-class crawler loader between the 125-series machines and the largest IH-Dresser loaders. It was produced through the IH and Dresser ownership eras, with the Dresser 175C following on as its direct successor. The 175 was specified for the harder duty cycles - mining loadout, quarry feed, demolition pick-and-carry, and industrial yard work - where the 125-class machines didn’t have enough bucket or breakout to keep up.

Engine, hydraulics, and drivetrain

The 175 runs a heavy IH / Dresser diesel through a refined drivetrain with steering-brake controls and a heavy-class undercarriage. Bucket capacity and breakout force are significantly higher than the 125-series, which is what puts the 175 into the production-loader category for quarry and mining work.

The implement hydraulic circuit feeds the loader lift and tilt cylinders. The main hydraulic pump - the 623084C92 on the Dresser cross-fit lineup - is a known service item, as are the lift and tilt cylinders themselves. The steering-brake system is a known wear point on this whole family of IH/Dresser TD7/TD8 and 100/125/175 machines.

Common service items on the 175

• Engine internals: IH / Dresser diesel pistons, rings, sleeves, head gaskets. The S.57678 head gasket set cross-fits this family.
• Cooling system: The 3132738R93 water pump fits IH / Dresser dozers and crawler loaders.
• Hydraulic system: 623084C92 main hydraulic pump (Dresser cross-fit). Loader bucket lift and tilt cylinder service.
• Steering brakes: The DBSKIT basic steering brake kit and DBSKIT-2 brake shoe kit are TD7/TD8 / 100/125/175 cross-fit brake service items. 621037C1 brake shoe.
• Operator station: PV862 seat package for IH / Dresser dozers and loaders. 621619C1 bottom seat cushion fits 100/125 loaders and TD7/TD8 dozers.
• Bucket / loader: Bucket cutting edges, teeth, pins and bushings, loader arm pivot service.
• Undercarriage: Track chains, rollers, idlers, sprockets, recoil springs.
• Electrical: Starter, alternator, gauges, switches, harness service.

Parts and cross-fit components for the IH-Dresser 175

What to verify before ordering

• Serial number. Confirm the machine serial on the 175 before ordering year-specific parts.
• Engine serial. Internal engine parts must match the engine serial number.
• Generation. IH-era and Dresser-era 175s saw multiple revisions - confirm by serial.
• Undercarriage spec. Track shoe count, roller and idler configuration vary by build - measure before ordering.
• Bucket configuration. Standard vs. heavy-duty bucket, multi-purpose vs. general purpose - cutting edges and teeth differ.

Why the 175 still earns a paycheck

The 175 is the heavy IH-Dresser crawler loader for mining, quarry, demolition, and industrial loadout. Operators who run them keep them because the bucket and breakout numbers hold up to duty cycles that put smaller loaders out of contention, and the parts cross-fit with the broader IH/Dresser TD7/TD8 and 100/125 family keeps support strong even on older machines.

Maintenance priorities on a 175: clean fuel for the IH/Dresser diesel, regular hydraulic system service, loader cylinder seal and rod service, and heavy-class undercarriage monitoring. Broken Tractor maintains parts coverage across the IH/Dresser loader family with verified cross-fits.
