Commercial and agricultural vehicle restoration

Commercial and agricultural restoration is about honest function as much as finish. These vehicles are larger, heavier and often built from thicker steel, but the rot is just as sneaky.

Assess the cab and chassis. Check the chassis rails, cross-members, outriggers and cab mounts. Commercial cabs rust at the bottom of doors, the windscreen surround, steps and the rear panel. Replace panels rather than filling large holes.

Mechanicals and drivetrain. Engines, gearboxes, axles and brakes are usually more robust than car parts, but every bush, bearing, brake actuator and hydraulic line needs checking. Rebuild the braking system end to end — it is not a place to save money.

Hydraulics and PTOs. Tractors and agricultural machines rely on hydraulic couplers, pumps and linkages. Renew hoses, check for contamination, and replace filters and seals before pressurising the system.

Cab and interior. Seats, headlining, floor panels and rubber matting take a beating. A comfortable cab is part of the usability of the finished machine, so do not leave it until last.

Paint and signage. Commercial vehicles often look best with a period livery, pin-striping and correct lettering. Take good photographs before stripping so you can recreate the original finish.
