Hydraulic Pump Rebuild Cost in Ames, Iowa
If you’re searching hydraulic pump rebuild cost because a loader, skid steer, or piece of ag equipment is losing power, whining under load, or barely lifting anymore, you’re asking the right question before you spend a dime. We rebuild hydraulic pumps on the bench every week at 210 Freel Dr in Ames, and hydraulic pump rebuild cost is almost always the first thing a customer wants to know before we pull the unit off the machine. The honest answer is it depends on what kind of pump you’ve got and how bad the internal wear is — but we can give you real ranges instead of a vague “it varies.”
How We Rebuild a Hydraulic Pump
The process is pretty consistent no matter what brand or size pump comes across the bench. We pull the pump, tear it down, and inspect the gears, vanes, or piston block for scoring. Scoring is the number one reason a pump dies early — dirty fluid or a failing seal lets contamination chew through the metal, and once that happens a straight seal-kit rebuild usually isn’t enough. That’s a big part of what drives hydraulic pump rebuild cost up or down on any given job.
- Remove pump from the machine and drain fluid for inspection
- Tear down and check gears, vanes, or piston block for scoring or heat discoloration
- Replace wear plates, shaft bearings, and internal seals
- Install new o-rings and case seals
- Bench test for pressure and flow before it ever goes back on the machine
- Reinstall, refill fluid, bleed the system, and road-test under load
Same as we see with cylinder rebuilds, if one hydraulic component has been running with contaminated or low fluid, it’s common for a second component on the same circuit to fail shortly after — we’ve seen a rebuilt cylinder blow out on the other side of a lift within weeks because the fluid problem was never fixed at the source. Pumps are no different, which is why we check the whole system, not just the part that quit.
Common Symptoms That Change Hydraulic Pump Rebuild Cost
Not every pump problem costs the same to fix. Here’s how the symptoms usually break down and what they tend to mean for hydraulic pump rebuild cost:
- Whining or cavitation noise — often a suction leak or worn shaft bearing, cheaper fix
- Slow, weak, or spongy lift — internal scoring on gears or vanes, mid-range rebuild
- Overheating hydraulic fluid — internal bypass from worn components, usually a full teardown
- Metal flakes in the fluid or filter — the case itself may be scored, which can push you past rebuild territory into full replacement
- Leaking shaft seal only, machine still has power — often just a seal swap, the least expensive option
If scoring inside the pump housing is bad enough, a rebuild won’t hold no matter how good the seal kit is — same story we run into on cylinder jobs where the bore is too far gone. When that happens on a pump, we’ll tell you straight before we button it up, because paying twice never sits right with us or with you.
How Much Does Hydraulic Pump Rebuild Cost
Real numbers from jobs we’ve done at the shop:
- Seal kit only, no internal wear — roughly $400 to $700 parts and labor
- Standard gear pump rebuild with bearings, shaft seals, and wear plates — roughly $900 to $1,800
- Piston pump rebuild with valve plate, servo, or swash plate work — roughly $1,800 to $3,500 and up depending on size
- Pump too scored to rebuild, replaced with new or reman unit — roughly $1,200 to $4,000+ depending on the machine
On top of parts and labor, if we’re coming to you instead of you hauling the equipment in, we bill mileage — typically a flat rate for round trips within about 40 miles of the shop, more beyond that. Hydraulic pump rebuild cost also climbs if we find the pump failure already took out a cylinder or the final drive from running contaminated fluid through the system — we cover that kind of combo repair over on our final drive rebuild page. If you’re trying to compare pump work against a cylinder repair on the same machine, our hydraulic cylinder rebuild cost guide breaks that down side by side, and we run the same kind of on-site work described on our Iowa cylinder rebuild page across the state.
Every hydraulic pump rebuild cost quote we give is based on what we actually find on the bench, not a guess over the phone — but we can usually tell you a ballpark range once you describe the symptoms and the machine. Call us at 515-292-2599 and we’ll walk through it with you before you decide whether a rebuild or a replacement makes more sense for your equipment.
Frequently Asked Questions
How much does a hydraulic pump rebuild usually cost?
Most rebuilds we do run between $400 and $3,500 depending on pump type and how much internal wear or scoring we find. Call 515-292-2599 with your symptoms and we’ll give you a ballpark before we tear it down.
Can you rebuild my pump or do I need a whole new one?
It depends on scoring inside the housing. If the gears, vanes, or piston block are scored too deep, a rebuild won’t hold long-term and we’ll recommend a replacement pump instead — we always tell you which situation you’re in before we button it back up.
What’s actually included in a hydraulic pump rebuild?
We remove the pump, tear it down, inspect for scoring, replace bearings and seals, install new o-rings, pressure test it on the bench, then reinstall, refill fluid, bleed the system, and road-test the machine.
Do you travel out to rebuild pumps on-site?
Yes, we do on-site work across the Ames area and beyond. We charge mileage for trips outside about 40 miles round trip from the shop at 210 Freel Dr.
Why did my pump fail again so soon after we changed the fluid?
If contamination already scored the internal gears or vanes before the fluid change, a fresh fluid fill won’t undo that damage. It’s common for a nearby cylinder or the final drive to be wearing out from the same contaminated fluid too, so we check the whole hydraulic circuit, not just the pump.
