Caterpillar Hydraulic Cylinder Repair in Fontana

Cat cylinders are built stout — and when one fails, the replacement price matches. Our Fontana shop rebuilds Caterpillar hydraulic cylinders in-house for wheel loaders, dozers, excavators and the rest of the Cat range, from compact-machine cylinders right up to large-bore work — priced like a working shop, not a parts counter.

Fontana, CA · Our hydraulic cylinder bench

Cat cylinders, from compact machines through to large-bore

Lift, tilt, blade, boom, stick and steering cylinders all follow the same route here: full teardown and measurement, barrels honed to finish, rods re-chromed or newly manufactured, reassembly with the seals the duty calls for — then a pressure test before release. The machine shop and cylinder bench share one building, so rod and barrel work never has to leave the property.

Built around machines that can't afford to sit idle

When a loader is down with a blown tilt cylinder, the whole job site is standing still. Our regular hours run Monday–Friday, 6 AM to 5 PM, and the rush line operates 24 hours a day, every day of the year — because cylinders don't fail to a calendar. Quotes and pick-up and delivery are free, and you'll talk directly with John Clark about the quickest practical route back to work.

  • Lift and tilt cylinders for wheel loaders
  • Blade and ripper cylinders for dozers

  • Large-bore honing and rod manufacturing
  • Seal replacement, finished with pressure testing

How a repair moves through our shop — 8 steps

From your first phone call to a machine or component that's been tested and put back to work, here's the route every job follows.

01

Collection

Where it applies, we arrange collection of the machine or part at no charge.

02

Teardown & check

We strip the unit down and assess the full extent of the failure.

03

Photo & video record

We photograph and film what we find, so the conversation about repairs starts from clear evidence.

04

Written quote

We spell out the work we recommend and price it before anything goes ahead.

05

Your go-ahead

Together we confirm what's being done, how urgent it is and the most sensible way forward.

06

Machine shop work

Components get machined, welded, rebuilt or reverse-engineered as the job requires.

07

Bench testing

Nothing leaves until operation and workmanship have both been checked.

08

Return

The finished part or machine goes back to you, ready to return to service.

Questions owners ask us

Will you take on large-bore Cat cylinders?

Yes — large-bore work is core business for our bench. We hone barrels in-house and re-chrome rods or manufacture them to size.

My Cat cylinder is leaking at the rod — what will it need?

A rod leak can come down to seals, a scored rod, or both together. We strip the cylinder, measure everything, then quote precisely what it needs — you'll never be sold a seal kit to cure a rod problem.
