The Fiat-Allis 14C and Its Industrial Heritage
The Fiat-Allis 14C motor grader was part of a lineage born from the merger of Fiat and Allis-Chalmers in the 1970s. Designed for road maintenance, site grading, and construction prep, the 14C featured a robust frame, mechanical simplicity, and a powerful diesel engine—often a Cummins or Fiat powerplant. With an operating weight of around 30,000 lbs and a moldboard width of 12 feet, the 14C was a mid-size grader that found favor in municipalities and private fleets across North America and Europe.
Though production ceased decades ago, many 14C units remain in service, thanks to their rebuildable components and straightforward hydraulics. Restoring one often includes repainting, which is both cosmetic and protective—especially for machines exposed to salt, sun, and abrasive materials.
Choosing the Right Paint System
Painting heavy equipment like the 14C involves more than aesthetics. The paint acts as a barrier against corrosion, UV degradation, and chemical exposure. Selecting the right system depends on budget, climate, and application method.
Recommended options include:
Surface Preparation Is Everything
Before painting, the surface must be clean, dry, and free of rust, oil, and loose paint. Skipping prep leads to peeling, bubbling, and premature failure.
Steps include:
Color Matching and Historical Accuracy
The original Fiat-Allis yellow varied slightly by year and production batch. While exact codes may be hard to find, close matches include:
A grader operator in Quebec painted his 14C in high-visibility orange to meet provincial safety standards. The machine stood out on snowy roads and passed inspection without issue.
Application Techniques and Equipment
Painting a grader requires patience and the right tools. Options include:
Protecting Decals and Identification Plates
Before painting, cover serial number plates, safety decals, and control labels. These are often required for registration, resale, or compliance. If damaged, replacements can be ordered from specialty suppliers or recreated using vinyl printing.
A grader in Texas failed DOT inspection due to missing load rating decals. He later sourced replacements online and reapplied them with clear coat for durability.
Post-Paint Maintenance and Longevity
To preserve the finish:
Conclusion
Painting a Fiat-Allis 14C motor grader is a rewarding process that enhances both appearance and durability. With proper surface prep, quality materials, and attention to detail, the machine can be restored to a condition that rivals its original factory finish. Whether for pride, resale, or preservation, a fresh coat of paint turns a workhorse into a showpiece—and keeps it working for years to come.

Choosing the Right Paint System
Painting heavy equipment like the 14C involves more than aesthetics. The paint acts as a barrier against corrosion, UV degradation, and chemical exposure. Selecting the right system depends on budget, climate, and application method.
Recommended options include:
- Alkyd enamel
Affordable and easy to apply. Offers decent gloss and protection but fades faster under UV.
- Acrylic urethane
More durable and UV-resistant. Requires hardener and proper ventilation. Ideal for long-term restoration.
- Epoxy primer with topcoat
Provides excellent adhesion and corrosion resistance. Often used in marine or industrial environments.
Surface Preparation Is Everything
Before painting, the surface must be clean, dry, and free of rust, oil, and loose paint. Skipping prep leads to peeling, bubbling, and premature failure.
Steps include:
- Pressure washing with degreaser
- Wire brushing or sanding rusted areas
- Applying rust converter to pitted metal
- Masking hydraulic lines, decals, and glass
- Priming with epoxy or etch primer for bare steel
Color Matching and Historical Accuracy
The original Fiat-Allis yellow varied slightly by year and production batch. While exact codes may be hard to find, close matches include:
- Federal Standard 595 color 33538 (industrial yellow)
- Caterpillar yellow (slightly deeper tone)
- Custom mixes from paint suppliers based on photos or samples
A grader operator in Quebec painted his 14C in high-visibility orange to meet provincial safety standards. The machine stood out on snowy roads and passed inspection without issue.
Application Techniques and Equipment
Painting a grader requires patience and the right tools. Options include:
- Brush and roller
Suitable for small areas or touch-ups. Leaves texture and brush marks.
- Airless sprayer
Covers large surfaces quickly. Requires masking and ventilation.
- HVLP spray gun
Offers fine control and smooth finish. Ideal for topcoat application.
- Rattle cans
Useful for small parts or hard-to-reach areas. Not recommended for full-body work.
Protecting Decals and Identification Plates
Before painting, cover serial number plates, safety decals, and control labels. These are often required for registration, resale, or compliance. If damaged, replacements can be ordered from specialty suppliers or recreated using vinyl printing.
A grader in Texas failed DOT inspection due to missing load rating decals. He later sourced replacements online and reapplied them with clear coat for durability.
Post-Paint Maintenance and Longevity
To preserve the finish:
- Wash regularly with mild soap
- Avoid harsh degreasers or solvents
- Touch up chips and scratches promptly
- Store indoors or under cover when possible
- Wax or seal the surface annually for added UV protection
