Hydraulic Pump Replacement Cost in Ames, Iowa
If you’re trying to figure out hydraulic pump replacement cost before you commit to a repair, you’re doing the smart thing. Pumps aren’t cheap, but neither is running a truck, lift, or piece of equipment on a pump that’s about to quit on you in the middle of a job. We’ve swapped gear pumps on flatbed trucks, rebuilt pumps for shop lifts, and replaced whole pump-and-valve assemblies for customers who couldn’t afford downtime. The honest answer on hydraulic pump replacement cost is: it depends on the pump, the machine it’s bolted to, and whether we’re rebuilding or replacing outright.
How We Handle Hydraulic Pump Replacement
When a pump comes into our shop or we go out to a truck or lift, the first thing we do is figure out if it’s actually the pump, or if it’s a starved pump because of a clogged filter, a bad relief valve, or a suction leak. We’ve seen plenty of pumps get blamed for problems that were really upstream. If you’re not sure whether your pump is even the problem, our page on hydraulic pump not building pressure walks through the diagnostic steps we use before we ever quote a replacement.
Once we confirm the pump is done, here’s roughly what the job looks like:
- Pull the old pump, inspect the shaft coupling, PTO hub, and mounting flange for wear or damage
- Match the new pump’s GPM rating and shaft spec to the application — we’ve installed 15 GPM gear pumps on lift equipment and higher-output pumps on flatbed truck hydraulics
- Replace or rebuild the relief valve if it’s not holding pressure, sometimes swapping in an adjustable relief valve rated up to 7000 PSI
- Reconnect hose barbs and JIC fittings, checking every O-ring seal on the way
- Fill with the correct fluid — we typically run ATF hydraulic fluid on lift equipment unless the manufacturer spec says otherwise
- Bleed the system and run it under load before we call it done
On flatbed truck hydraulics, most of the hydraulic pump replacement cost is labor — accessing the pump behind the frame rail or under the bed takes time, even when the part itself is straightforward. On shop lifts, we’ve done full jobs that include a new pump, new valves, installation, and delivery mileage within 100 miles of our shop, all bundled into one ticket.
Signs Your Pump Is Failing (Not Something Else)
Before you budget for hydraulic pump replacement cost, make sure the pump is actually the culprit. Common symptoms we see at the bench:
- Whining or growling noise — usually cavitation from a clogged suction filter or low fluid, not always a bad pump
- Slow or weak lift/lower — could be a worn pump, but also check the relief valve setting first
- No pressure at all — worn gears or a sheared shaft key, this is almost always a pump issue
- Overheating fluid — internal pump leakage bypassing flow back to tank
- Metal shavings in the filter — the pump is eating itself from the inside, replace it now before it takes the valve block with it
We deal with this constantly on gear pumps used in material handling equipment — if that’s your situation, our material handling hydraulic repair page covers the specific failure patterns we see on forklifts and lifts around Iowa. And if your pump is a Blackmer or similar rotary vane unit, we’ve got a dedicated troubleshooting guide at Blackmer pump troubleshooting that might save you a replacement altogether.
How Much Does Hydraulic Pump Replacement Cost
Real numbers from jobs we’ve actually billed:
- Gear pump rebuild: $250-$600 in labor and parts, depending on wear on the gears and housing
- Straight pump swap on a shop lift: $1,200-$3,000 including new pump, valves, installation, and delivery mileage
- Flatbed truck hydraulic pump replacement labor alone: $400-$900, plus the pump itself which can run $300-$1,500 depending on GPM and PTO configuration
- Full pump-and-relief-valve replacement with adjustable 7000 PSI relief valve: $800-$2,000
- Shop labor rate: billed per hour, plus mileage if we’re coming to you within 100 miles of our Ames shop
Hydraulic pump replacement cost climbs fast if the pump failure took out other components — a chewed-up gear pump can send metal into the relief valve, the hoses, even the cylinder seals. That’s part of why we always check the whole system, not just swap the pump and send you on your way. If your cylinders are also showing wear from running dirty fluid, take a look at our hydraulic cylinder rebuild cost guide so you know what you might be looking at there too.
We know hydraulic pump replacement cost is money you didn’t plan to spend. Our job is to make sure you’re only paying for what actually needs fixing, not a guess. Call us at 515-292-2599 and tell us what the machine is doing — we’ll give you a straight answer on whether it’s a rebuild, a replacement, or something cheaper altogether.
Frequently Asked Questions
How much does hydraulic pump replacement cost on a flatbed truck?
Labor alone usually runs $400-$900 depending on how buried the pump is, plus the pump itself, which can add $300-$1,500 depending on GPM and shaft configuration. We quote it after we see the truck.
Can you rebuild my pump instead of replacing it?
Often, yes. If the housing and shaft are still good, a gear pump rebuild runs $250-$600, which is a lot cheaper than a full replacement. We check wear before we quote either option.
What’s included when you replace a pump on a shop lift?
Typically the new pump, valves, installation labor, and delivery mileage if we’re coming to your location within 100 miles of our shop in Ames.
Why does my pump keep whining even after we added fluid?
That’s usually cavitation from a clogged suction filter or air getting pulled into the line, not the pump itself. We check that before recommending a full pump swap.
Do you work on equipment outside Ames?
Yes, we travel to jobsites and shops within 100 miles of our location at 210 Freel Dr, Ames, IA. Call 515-292-2599 and we’ll figure out logistics.
