Hydraulic Cylinder Repair Bench in Ames, Iowa
Every cylinder that limps into our shop ends up on the same hydraulic cylinder repair bench — the same hone, the same seal stock, the same measuring tools we’ve used on hundreds of jobs out of our building at 210 Freel Dr. If your loader arm sags overnight or your excavator boom won’t hold a load, that cylinder needs to come off the machine and onto our hydraulic cylinder repair bench before anyone can tell you what’s actually wrong inside the tube.
How we work on a hydraulic cylinder repair bench
We pull the cylinder off the machine first — there’s no shortcut here, you can’t rebuild a barrel while it’s still hanging on a boom. Once it’s on our hydraulic cylinder repair bench, we split it down, pull the rod, and check the bore for scoring, pitting, and chrome wear on the rod itself. A lot of the leaks we see aren’t bad seals at all — they’re a scored rod or a scratched bore that’s been chewing through every seal kit you put in it. We measure everything before we quote a fix, because guessing at a cylinder job wastes your money and our time.
Once we know what we’re dealing with, the work on the hydraulic cylinder repair bench usually breaks down like this:
- Remove cylinder from the machine and tag hoses/fittings
- Disassemble on the hydraulic cylinder repair bench and inspect rod, bore, and glands
- Replace head seal, piston seal, U-seals, and wiper seal to spec (we stock common sizes like 3″ x 0.062″ head seals and 1-1/2″ x 3″ wiper seals)
- Hone or sleeve the bore if scoring is light; recommend a new cylinder if it’s not
- Reassemble, pressure test, reinstall, and bleed the system on the machine
For folks outside Ames, we’ve done this same work for equipment owners near Winterset and excavator operators around Boone, so the process on our hydraulic cylinder repair bench doesn’t change just because the machine drove in from a different county.
Common cylinder failures we find on the bench
Most of what lands on our hydraulic cylinder repair bench falls into a handful of patterns. Rod scoring from dirt or a bad wiper seal is the big one — once the rod’s scored, it’ll cut through a fresh seal in weeks if we don’t address the surface itself. Bore scoring is the other common culprit, usually from the same contamination working its way past a worn wiper. We also see rusted-out lock cylinders and cover bolts on lift equipment that’s been sitting outside, and cracked or pitted glands on cylinders that have been run low on fluid.
Here’s the part we tell every customer up front: it’s really common for the other cylinder on a two-cylinder setup — think a lift and tilt pair, or dual lift cylinders on a rotary lift — to blow out shortly after we rebuild the first one. Both cylinders have usually been running the same hours under the same load, so if one’s scored, the other is often right behind it. We don’t rebuild the second one preemptively unless you ask us to, but we do warn you it’s coming.
If a rebuild doesn’t hold — meaning the bore is too far gone to seal reliably even after honing — you’re looking at a new cylinder instead of another round of seals, which typically adds $300 to $800 to the job depending on the cylinder size and whether it’s a stock part or something we have to source. That’s not us upselling you; that’s just what scored steel does to a fresh seal kit.
How much does a hydraulic cylinder repair bench rebuild cost
Straightforward seal kit rebuilds on smaller cylinders — think a lock release cylinder on a rotary lift — run in the $145 to $400 range for parts and labor combined, depending on seal availability. A full rebuild on a mid-size loader or skid steer cylinder, including removal, bench work, reseal, reinstall, and bleed, generally lands between $450 and $900. Larger excavator or backhoe cylinders with more seal sizes and heavier honing work can run $900 to $1,800, especially if the bore needs sleeving instead of just honing.
A few things that move the number up or down on any hydraulic cylinder repair bench job:
- Whether the rod or bore needs honing/sleeving versus just new seals
- Availability of the exact seal kit — some odd sizes take longer to source
- Rusted bolts or hardware that need replacing along with the seals
- Whether we’re doing a shop drop-off or a mobile pickup — mileage runs 40 miles round trip at no charge from our Ames location, beyond that we add a trip fee
- Whether the rebuild holds or the cylinder needs full replacement (add $300–$800)
For a more detailed breakdown by cylinder type and machine, our cylinder rebuild cost guide walks through more specific numbers, and if you’re comparing rebuild-vs-replace on a final drive too, we’ve got notes on that over on our final drive rebuild page as well.
If a cylinder on your equipment is leaking, drifting, or just not holding pressure the way it used to, get it to our hydraulic cylinder repair bench before it takes out a hose, a pump, or the cylinder next to it. Call us at 515-292-2599 and we’ll walk you through what it’ll take to get it back on the machine and holding.
Frequently Asked Questions
How long does a cylinder stay on your hydraulic cylinder repair bench?
Most straightforward reseals are done same-day or next-day once the cylinder is off the machine. If we’re honing the bore or waiting on an odd-size seal kit, plan on 2-4 business days.
Can you rebuild a cylinder without removing it from the machine?
No — the cylinder has to come off and go on the hydraulic cylinder repair bench so we can properly inspect the bore and rod. Trying to reseal it in place almost always leads to a repeat leak.
What if the rebuild doesn’t hold?
If the bore is scored too badly to seal reliably even after honing, you’ll need a new cylinder instead, which typically adds $300 to $800 depending on size and sourcing.
Do you work on cylinders from equipment outside Ames?
Yes, we regularly pull cylinders from machines near Winterset, Boone, and other spots around central Iowa and bring them back to our hydraulic cylinder repair bench in Ames.
How much does a basic cylinder reseal cost?
Smaller cylinders, like a lock release cylinder, generally run $145 to $400 for parts and labor. Larger loader or excavator cylinders run higher — see our cost guide for specifics.
