Hydraulic Cylinder Seal Replacement Near Me — Ames Hydraulics
When a rod starts weeping oil or a lift arm won’t hold its load anymore, most people around here start typing hydraulic cylinder seal replacement near me into their phone at two in the morning. If that’s how you found us, good — this is what we do at the bench every week, whether it’s a loader arm cylinder off a skid steer, a tilt cylinder on a dump bed, or the lift cylinder under a car hoist that’s been leaking down onto the shop floor.
We’re a family-run shop at 210 Freel Dr in Ames, and hydraulic cylinder seal replacement near me isn’t just a phrase we typed into a webpage — it’s the bulk of our week. We’ve pulled cylinders with scored barrels, pitted rods, blown wiper seals, and piston seals that gave up after years of heat cycling and dirt working past a cracked wiper. Bring the whole machine or just the cylinder, and we’ll get it apart, measured, and rebuilt right.
How We Handle Hydraulic Cylinder Seal Replacement Near Me
Every job starts the same way — we pull the cylinder, drain it, and get it stripped down on the bench so we can see exactly what’s going on inside. Scoring on the barrel wall or a rod that’s out of round changes the whole plan, so we don’t skip that step just to save time.
- Remove the cylinder from the machine or lift
- Disassemble and inspect the barrel, rod, and gland for scoring or pitting
- Measure and match head seals, piston seals, U-seals, and wiper seals to the exact bore and rod size
- Rebuild with new seal kits — we’ve used parts like HS686-342 head seals and MCU-1500-D wiper seals depending on the cylinder
- Reinstall, refill, and bleed the system so there’s no air trapped in the lines
If you’re outside town, we still cover you — we run mileage service to locations within 30 to 40 miles of the shop with no trailer needed for most jobs, which covers a good chunk of central Iowa. For bigger equipment like excavators, our excavator cylinder rebuild service out of Boone uses the same process, just scaled up for bigger bores and heavier rods.
Common Signs You Need Hydraulic Cylinder Seal Replacement
Most people don’t call us until the cylinder is already dripping onto the concrete, but there are earlier warning signs worth watching for:
- Oil weeping or streaking down the rod, especially after the machine sits overnight
- A lift arm, bucket, or tilt cylinder that slowly drifts down under its own weight
- Jerky or chattering movement instead of smooth extension and retraction
- Visible scoring or a rough feel when you run a fingernail down the rod
- Low fluid levels with no obvious external leak anywhere else in the system
Any one of those is a good reason to search hydraulic cylinder seal replacement near me before the cylinder gets bad enough to score the barrel — because once it’s scored, a simple seal kit won’t fix it anymore. That’s the difference between a $300 rebuild and a $800+ full cylinder replacement, and we’ll always tell you honestly which side of that line you’re on.
How Much Does Hydraulic Cylinder Seal Replacement Cost
Pricing depends on the size of the cylinder, how bad the scoring is, and whether we’re pulling one cylinder or a matched pair. A few real numbers from jobs we’ve done recently:
- Small lock or release cylinders (like the SL20430B on a rotary lift): around $145 plus labor
- Standard cylinder rebuild with new seals, no scoring found: typically in the $300 range
- Rebuild that turns up scoring bad enough to need a full new cylinder: add roughly $300 to $800 on top of the rebuild cost
- Mileage for shop visits within 30 to 40 miles, no trailer: a flat trip charge added to the invoice
We’ve also seen it common for the other cylinder on a two-cylinder setup — like a car lift or loader — to blow out shortly after we rebuild the first one, simply because it’s been carrying the same load and hours. We’ll flag that possibility up front instead of letting it surprise you later. For a fuller breakdown of pricing across different cylinder sizes, our cylinder rebuild cost guide walks through more scenarios.

Frequently Asked Questions
How long does hydraulic cylinder seal replacement take?
Most single-cylinder jobs take one to two days once it’s on our bench, depending on whether the barrel or rod needs machining beyond a standard seal kit swap.
Can you do hydraulic cylinder seal replacement without removing the whole machine?
In most cases yes — we can pull just the cylinder and leave the rest of the machine in place, which saves time and keeps the bill down.
What if the cylinder is scored and seals alone won’t fix it?
We’ll show you the scoring and explain your options. Sometimes we can hone the barrel, but bad scoring usually means a new cylinder, which typically adds $300 to $800 depending on size.
Do you travel outside Ames for hydraulic cylinder seal replacement near me jobs?
Yes, we run mileage service within about 30 to 40 miles of our shop at 210 Freel Dr with no trailer needed for most cylinders.
How much does a basic cylinder rebuild cost?
A straightforward rebuild with new seals and no scoring typically runs around $300, not counting mileage or parts like specialty seal kits.
