Machine History
The Galion motor grader with a UD-16 engine is a classic piece of construction equipment dating back to the late 1950s or early 1960s. Galion, founded in 1907 in Ohio, became known for durable graders used in state and municipal road departments. These early models were often ex‑State Department of Transportation units, meaning they saw consistent maintenance but heavy use. The UD-16 engine, a diesel inline-six, powered these machines reliably, offering roughly 160–180 hp depending on tuning and era. This engine was known for longevity and simplicity, which made parts replacement feasible even decades later.
Design and Features
The grader’s design emphasizes mechanical simplicity:
Due to age, several maintenance challenges exist:
Because Galion discontinued many models in the 1970s, sourcing parts for a UD-16 grader is challenging. Recommended strategies include:
Owners report that even decades-old UD-16 graders perform well if:
Galion graders of this era are notable for being exposed to state-level road maintenance, which gives them a history of heavy-duty use and well-documented maintenance schedules. Collectors and small contractors value them for:
The Galion motor grader with a UD-16 engine is a rare vintage machine, exemplifying mid-20th century heavy equipment engineering. While parts sourcing and maintenance require ingenuity due to its age, proper care of the steering gearbox, hydraulic cylinders, and diesel engine can keep it operational for decades. Collectors and operators interested in historical graders often invest in restoration, custom fabrication, and careful mechanical upkeep to preserve these enduring machines.

Design and Features
The grader’s design emphasizes mechanical simplicity:
- Steering system: Fully mechanical linkage with a manual gearbox; the operator turns the wheel, and a series of shafts and gears move the front wheels. A steering gearbox shaft is a key component prone to wear.
- Blade control: Hydraulic cylinders allowed raising, lowering, and tilting the moldboard. Early models had single‑cylinder hydraulic lift, limiting speed but ensuring robustness.
- Frame and chassis: Heavy steel frame capable of supporting a long moldboard (often 14–16 ft) and resisting torsion during grading operations.
- Engine compartment: The UD-16 diesel is naturally aspirated, water-cooled, and equipped with mechanical fuel injection, making it easier to repair in the field.
Due to age, several maintenance challenges exist:
- Steering gearbox and shaft wear: Bearings and splines often degrade, causing play in the front wheels. Replacement parts may need to be custom-machined or sourced from salvage units.
- Hydraulic cylinder seals: Rubber deterioration over decades can lead to leaks and reduced blade responsiveness.
- Engine components: While UD-16 engines are robust, injector nozzles, pump timing, and valve seats may require overhaul.
- Electrical system: Early models rely on 12 V or even 6 V systems; wiring insulation becomes brittle, causing intermittent failures.
Because Galion discontinued many models in the 1970s, sourcing parts for a UD-16 grader is challenging. Recommended strategies include:
- Salvage yards and auctions: Often the best source for rare mechanical components like gearbox shafts and hydraulic parts.
- Custom fabrication: Local machine shops can reproduce worn shafts or brackets to original tolerances.
- Interchangeable parts: Some components are compatible with later or similar models from Galion or other manufacturers.
- Documentation and measurement: Since model numbers may be missing, careful measurement of parts ensures replacements fit correctly.
Owners report that even decades-old UD-16 graders perform well if:
- Hydraulic oil is replaced regularly to maintain cylinder function.
- Mechanical linkages are lubricated daily, particularly in steering and blade control.
- Engine tuning is monitored, including injector timing and valve adjustment every 500–1,000 hours.
Galion graders of this era are notable for being exposed to state-level road maintenance, which gives them a history of heavy-duty use and well-documented maintenance schedules. Collectors and small contractors value them for:
- Durability: The cast-steel frame and simple hydraulic layout survive long-term use.
- Ease of repair: Mechanical simplicity allows owners to perform most repairs without factory service.
- Heritage value: Early UD-16 graders represent a period in construction machinery when reliability and longevity outweighed speed and electronic automation.
