Caterpillar Hydraulic Cylinder Repair in Fontana
Cat cylinders are built stout — and carry a stout price tag when they fail. Top Notch Equipment Repair rebuilds Caterpillar hydraulic cylinders in Fontana for wheel loaders, dozers, excavators and the rest of the line, compact machines through large-bore work, at a working shop's rate instead of a parts-counter rate.
Hydraulic cylinder bench · Fontana, CA
Cat cylinders, from compact machines to large-bore
Lift, tilt, blade, boom, stick and steering cylinders are torn down and measured one by one. Barrels are honed back to finish, rods re-chromed or manufactured new, and each cylinder is reassembled with seals matched to its duty, then pressure-tested before release. The machine shop shares a building with the cylinder bench, so rod and barrel work never leaves the property.

Frequently asked questions
Do you rebuild large-bore Cat cylinders?
Yes — large-bore cylinders are core work for our bench. Barrels are honed in-house and rods are re-chromed or manufactured to size.
My Cat cylinder leaks at the rod. What does it need?
Rod leakage can be seals, a scored rod, or both. We strip and measure the cylinder, then quote exactly what it needs — no seal kit sold for a rod problem.
