Caterpillar Hydraulic Cylinder Repair in Fontana
Cat cylinders are built heavy — and priced accordingly when they fail. Our Fontana shop rebuilds Caterpillar hydraulic cylinders for wheel loaders, dozers, excavators and the rest of the Cat line in-house, from compact-machine cylinders to large-bore work, at a working shop's price instead of a parts-counter price.

Cat cylinders, from compact machines to large-bore
Lift, tilt, blade, boom, stick and steering cylinders: each one is torn down and measured, barrels are honed to finish, rods are re-chromed or manufactured new, and the cylinder goes back together with the correct seals for its duty — then it is pressure-tested before it is released. The machine shop and the cylinder bench are in the same building, so barrel and rod 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.
