Parker Hannifin Hydraulic Cylinder Repair in Fontana
Parker Hannifin cylinders show up everywhere hydraulic power does real work — tie-rod cylinders on presses and plant machinery, welded cylinders on loaders, refuse trucks and mobile equipment, telescopic cylinders on dump bodies. Our Fontana cylinder bench rebuilds Parker cylinders in-house: complete teardown, honest measurement of bore, rod and piston, and the machine work to return the cylinder to its working clearances before it is resealed and pressure-tested.

Tie-rod, welded and telescopic Parker cylinders
Each construction fails differently, and the bench treats it that way. Tie-rod industrial cylinders are measured for barrel wear and rod condition and rebuilt with seals matched to the fluid and duty. Welded mobile cylinders get the same measurement discipline, with bent or scored rods re-chromed or manufactured new on our own machines instead of straightened. Telescopic stages are checked stage by stage for the scoring and seal wear that makes a dump body creep, shudder or stop short of full lift.

Quoted from measurements, not from a parts list
A Parker cylinder that keeps eating seals is not a seal problem — it is a rod finish, a barrel, or a misalignment problem wearing a seal costume. We strip the cylinder and measure before we quote, so the price you approve is the repair the cylinder actually needs. Regular hours are Monday–Friday 6 AM–5 PM; the rush line runs 24 hours a day, every day of the year. Quotes are free, pick-up and delivery are free, and you talk directly with John Clark.

Frequently asked questions
Can you rebuild a Parker tie-rod cylinder from a press?
Yes — industrial tie-rod cylinders are regular bench work here. We measure bore, rod and piston at teardown, renew what is worn, and pressure-test the rebuilt cylinder before it goes back.
My telescopic dump cylinder creeps down under load. Can that be fixed?
Usually, yes. Creep points to stage seal wear or scoring on a stage. We inspect stage by stage, repair or renew what is damaged, and test the cylinder through its full stroke.
