Look over a cart before every trip: linchpins in place, wheels tight on their axles, axles greased, shafts without cracks, and joints and lashings sound. Carry spare linchpins, cordage and grease, and learn the roadside fixes: drill a hole at the tip of a crack to stop it spreading, splint a broken shaft with a sister pole lashed alongside, and shim a loose wheel with thin leather or rawhide.
Part of Cart & Wagon Construction
Cart maintenance is the routine inspection, lubrication and repair that keeps a hand-built cart or wagon from failing on the road.
Most Failures Show Up Before They Happen
A cart fails where it is highly stressed, worn or dry: the axle, the wheel hub, the shafts and the joints. Most of these give warning in advance: a wheel that wobbles, a shaft that creaks, a hub that runs hot, a lashing that has stretched. A short inspection before each trip finds them.
The Pre-Trip Check
| Part | Look and feel for |
|---|---|
| Linchpins and washers | present, tight, tethered, no spare missing (Axle Pin & Retention) |
| Wheels | spin freely, rim wobble no worse than before, no new cracks |
| Hubs and axle | grease present and clean; hub not hot after the first kilometre (Lubrication & Wear) |
| Shafts | no cracks or splits, joints at the frame firm |
| Bed and joints | pegs and lashings tight, floor sound |
| Iron tires, if fitted | tap with a hammer: a ring means tight, a dull rattle means loose |
What You Need In The Spares Kit
- Spare linchpins, at least two per wheel
- Cordage and wire for lashing
- Grease or tallow
- Hardwood pegs and a spare pole for splicing
- Thin leather or rawhide for shims
- An axe, drill or auger, and a mallet
Common Failures And Roadside Fixes
The fixes in the parent article, with the wheelwright fixes added:
- Loose wheel on a solid disc: the hub hole has worn oversize. Glue thin leather or rawhide shims inside the hub.
- Cracked disc wheel: if the crack has not reached the hub, drill a hole at the crack tip to stop it spreading, then batten across the crack with pegs.
- Worn axle arm: wrap it with thin iron strip, or build it up with a hardwood sleeve pegged in place.
- Broken shaft: splice a sister pole alongside the break and lash it. This is temporary; replace the shaft when you can.
- Loose tire on a spoked wheel, or a broken spoke: see Wheelwright Craft and Wheel & Axle Repair.
Common Mistakes
- Driving on with a warm-then-hot hub — a dry bearing chars and seizes.
- Starting out with no spare linchpin — a lost wheel on a loaded cart in rough terrain is a serious problem.
- Treating the splint as permanent — a sister-pole shaft still has a break in it.
- Skipping the pre-trip check on a short trip — a loose pin or dry hub fails just as well within a kilometre.
Safety
Never work under a cart held by a jack, and chock before unhitching
A loaded or tipping cart is a crushing hazard. Chock the wheels before unhitching, prop the shafts, support a lifted axle on blocks rather than on a jack, and never stand or work downhill of a loaded vehicle. Unload before repairing.
