What a hydraulic cylinder reseal costs versus replacement
Three outcomes, three prices, one decision made with the cylinder open on the bench. The numbers here are the ones on our cost page, and the reasoning is what we say on the phone.
A hydraulic cylinder reseal in Woodland costs $350 to $900 on a cylinder under 3 inch bore, and $400 to $1,100 on a forklift mast or tilt cylinder. A full rebuild on a large bore cylinder, 3 inch and up, runs $1,000 to $3,000, and if the rod needs rechrome or replacement that adds $400 to $1,500. Replacement means buying a new cylinder, and its price depends on the make and whether the dealer or the aftermarket has one on the shelf that week, so we quote it live rather than print it. The useful question is not which is cheapest on paper. It is which one the cylinder in front of you actually needs, and that is decided by three findings after the gland comes out. Capay Hydraulics opens every cylinder before confirming a number, and this guide walks through how the call gets made.
What a reseal is, and when it is enough
A reseal is new seals, wear rings and wiper on a rod and a bore that are both still sound. The kit for a common Deere, Case, Cat, Bobcat or forklift cylinder is $150 to $400 and stocked here. The labor is two to four hours in the shop at $125 to $155 an hour. That is how the $350 to $900 range is built, and the swing inside it comes from the gland condition, whether the kit is on the shelf or dealer only, and whether the rod needs a polish before the new seals go in.
A reseal is the right answer when the symptom is weeping at the rod with clean chrome underneath, or mild bleed-down under load on a cylinder whose bore measures true. Those are the majority of header lift cylinders, loader tilt cylinders, implement lift cylinders and forklift tilt cylinders that come through the door. With the kit in stock the turnaround is usually one day.
The three findings that turn a reseal into a rebuild
- Rod damage. Pitting from a wet winter layup, a bend from side loading, or chrome worn through at the gland. This is the single biggest swing on any cylinder. New seals on a pitted rod are cut within weeks, so the rod gets polished, straightened, rechromed or replaced first. Rechrome or a new rod is $400 to $1,500 on top of the rebuild, and the chrome shop adds four to seven days.
- Bore scoring. Light scoring from grit past a worn wiper hones out and the cylinder stays in the rebuild range. Deep scoring from a failed piston ring or a piston that ran metal on metal does not hone out, and at that point the barrel is the problem, not the seals.
- Piston and gland wear. A piston with worn ring grooves or a gland with a damaged seal land will not hold new seals square. Replacing them is part of what makes a rebuild $1,000 to $3,000 instead of a reseal price.
A rebuild with honing and a new piston takes two to three days on the bench, plus the chrome turnaround if the rod goes out. Every rebuild is cycled and held at working pressure on the test stand before it leaves, and carries a one year workmanship warranty.
When replacement is the honest answer
A new cylinder wins in three situations. The first is a barrel scored past honing, because a new barrel plus a rod plus internals is most of a new cylinder anyway. The second is a bent rod on a cylinder where a new rod costs nearly as much as the whole unit, which happens on small welded cylinders for common loaders and implements that the aftermarket sells cheaply. The third is time: when the rebuild needs a chrome shop and the machine is cutting tomorrow, a dealer cylinder that ships overnight can be worth the difference in price.
We do not print a new cylinder price because it moves with the maker, the bore and stroke, and what is in stock that week. What we do is put the rebuild estimate next to the new unit price on the same phone call, and say which one we would buy if it were our machine. On an older tractor or harvester the dealer has stopped supporting, rebuild is often the only option, and those cylinders rebuild well.
The costs people forget on both sides
- Getting it off the machine. If the truck pulls the cylinder at your yard or field, the trip fee of $150 to $235 and field labor at $145 to $185 an hour apply, and they apply whether a reseal or a new unit goes back on. Drop the cylinder at the shop in Woodland and that line is zero.
- The other cylinder in the pair. Lift and tilt cylinders come in twos and age together. When one needs seals, the second is usually a season behind. Doing both on one pull saves the second trip fee and a second day down.
- Contamination. If the cylinder failed because metal from a dying pump came through it, a new cylinder or a fresh rebuild dies the same way unless the system is flushed. The flush is quoted separately and we say when it is needed.
- Warranty. Our rebuilds carry one year on workmanship and supplied parts. A new cylinder carries the maker warranty, which is worth checking for aftermarket units before assuming it is longer.
Two examples off the table
A loader tilt cylinder on a mid size tractor comes in weeping at the rod. Bore under 3 inches, chrome clean, bore true. That is a reseal, and with the kit on the shelf it lands near the bottom of the $350 to $900 range and goes home the next day.
A walnut shaker clamp cylinder comes in creeping under load in October. Bore over 3 inches, piston seals bypassing, rod pitted along the top where dust sat on it all summer. That is a rebuild in the $1,000 to $3,000 range, plus rod work at $400 to $1,500, and the honest conversation is about the chrome shop turnaround against the weeks left in the season. If a new clamp cylinder is on a dealer shelf in the valley, that gets priced next to the rebuild before anyone decides.
How to make the call in one phone conversation
- Describe the symptom: weeping at the rod, creeping under load, or slow on one function.
- Tell us the bore size if you know it, or the machine and which cylinder it is.
- Look at the rod with the machine off and pressure relieved. Pitting, scoring or a visible bend changes the answer before the cylinder is even off.
- Say how many days the machine can be down.
- Decide whether you are bringing it in or the truck is pulling it.
With those answers you get a range off the cost page on the first call and a confirmed number once the cylinder is open. For what happens at the field edge, including when the truck can finish a job on site, read the guide to mobile repair for orchard and row crop equipment.
Reseal and rebuild questions
Can I just replace the seals myself and save the labor?
On a small cylinder with a clean rod, some people do. The two things that go wrong are the gland, which needs the right spanner and often a press, and the rod, which you cannot see the damage on until the seals are out. If you open it and find pitting, stop and bring it in, because new seals on a pitted rod last weeks.
Why does a rebuild cost so much more than a reseal?
Because it is a different job. A reseal is a $150 to $400 kit and two to four hours of shop labor at $125 to $155 an hour. A rebuild adds honing the bore, straightening or replacing the rod, a new piston and gland where needed, and test stand time. The parts alone can pass the price of a reseal before the labor starts.
Do you tell me before you spend money on a rod?
Yes, every time. The cylinder is opened, measured and photographed, and you get the number and the reason before any parts are ordered. If the honest answer is a new cylinder, you hear that too.
What warranty is on a resealed cylinder?
Rebuilds carry a one year warranty on our workmanship and the parts we supplied. A reseal on a rod we advised replacing is done at your call and we say in writing that the seals will not last, so nobody is surprised.
