Hydraulic Motor Repair Near Me — Ames Hydraulics, Ames IA
When somebody types hydraulic motor repair near me into their phone, they’re usually standing next to a piece of equipment that just quit moving. A rail saw won’t spin. A skid steer wheel motor is leaking down faster than the pump can keep up. A gear motor on a conveyor is grinding instead of turning smooth. We’ve seen all of it come through our bay at 210 Freel Dr, and if you’re in Ames or anywhere in central Iowa searching hydraulic motor repair near me, we’re the shop that actually opens the motor up instead of just swapping it and hoping.
We rebuild hydraulic motors on the bench — gear motors, piston motors, vane motors, orbital motors, you name it. Just recently we had a WH 04-1023Y Piusa hydraulic motor come in, a 6.2:1 ratio unit with a dual-port H-shaft and SAE A flange, fitted with a 6400-12-10 adapter running 3/4 male JIC to 5/8 male O-ring boss. That kind of job is typical bench work for us: pull the motor, tear it down, inspect the shaft splines and gerotor set, and put it back together with fresh seals so it runs like it did when it left the factory.
How We Handle Hydraulic Motor Repair Near Me
Our process doesn’t change much whether the motor came off a skid steer, a mower deck, or an industrial rail saw. Here’s what actually happens on our bench when you bring us a job for hydraulic motor repair near me:
- We drain the motor and inspect the case drain and shaft seal first — that’s where most leaks start.
- We pull the motor apart and check the gerotor set, rotor, or piston block for scoring, pitting, or excessive wear.
- We measure shaft runout and spline wear, especially on H-shaft and keyed-shaft motors like the Piusa units we work on often.
- We replace all seals, including back-up rings and shaft seals, using OEM-spec parts like the MDS and NBR back-up rings we keep in stock.
- We pressure test the rebuilt motor on our test stand before it ever goes back on your machine.
- We reassemble with correct port fittings — JIC, O-ring boss, SAE flange — matched to your hydraulic system.
On two separate rail saw jobs recently, the motor itself was too far gone to rebuild economically, so we replaced the hydraulic motor on the rail saw outright and tested it under load before sending it back out. That’s part of honest hydraulic motor repair near me too — sometimes rebuilding costs more than a fresh unit, and we’ll tell you straight when that’s the case.
Common Signs Your Hydraulic Motor Is Failing
Most folks calling us for hydraulic motor repair near me describe one of these symptoms. If any of this sounds familiar, don’t wait until the motor locks up completely:
- Slow or weak rotation — internal wear in the gerotor set or piston block is letting oil bypass instead of turning the shaft.
- Grinding or knocking noise — usually bearing wear or a damaged shaft spline.
- Oil leaking from the case drain — a worn shaft seal, often the first sign of internal wear.
- Motor stalls under load — could be the motor, or it could be upstream. If your pump isn’t building pressure at all, that’s a different problem — check out our page on hydraulic pump not building pressure before assuming the motor is the culprit.
- Erratic speed or jerky movement — often points to internal cross-porting inside the motor housing.
We diagnose all of this on-site whenever we can, which is part of why folks search hydraulic motor repair near me instead of shipping a motor off to a mail-order rebuilder three states away. You get your equipment back faster, and you get to talk to the person who actually worked on it.
How Much Does Hydraulic Motor Repair Near Me Cost
Costs depend heavily on motor type and how far gone the internals are, but here’s what we typically see:
- Seal kit replacement only (shaft seal, O-rings, back-up rings): $150–$350 in parts and labor
- Full gerotor or piston-block rebuild with new bearings: $400–$900 depending on motor size
- Large SAE A/B flange motors like the Piusa units we service: $500–$1,100 rebuilt
- Full motor replacement when a rebuild isn’t cost-effective: $600–$2,500 depending on displacement and manufacturer
- Shop labor for diagnostics and drive-up service: billed hourly, quoted before we start
Every quote includes parts, labor, and Iowa sales tax where applicable — no surprise line items when you pick the equipment up. If your equipment also has a cylinder that’s dripping or losing pressure, it’s often cheaper to handle both at once — see our hydraulic cylinder rebuild cost guide for what that side of the job runs. And if this is a plow or material handling rig, our material handling hydraulic repair page covers the systems these motors usually live inside.
If you’re typing hydraulic motor repair near me because something on your farm, jobsite, or shop floor stopped turning, call us at 515-292-2599. We’ll tell you honestly whether it’s a seal kit or a full rebuild, quote it before we touch anything, and get you back running out of our shop at 210 Freel Dr in Ames.
Frequently Asked Questions
Do you repair hydraulic motors or only replace them?
We do both. Most gear and piston motors can be rebuilt on our bench with new seals, bearings, and internal components. We only recommend replacement when the housing or shaft is damaged beyond repair.
How long does hydraulic motor repair near me usually take?
A straightforward seal kit rebuild can often be done same-day or next-day. Full internal rebuilds with parts ordering typically take 2-5 business days depending on availability.
Can you rebuild orbital and wheel motors, not just gear motors?
Yes. We work on gear motors, piston motors, vane motors, and orbital wheel motors used on skid steers, mowers, saws, and material handling equipment.
What brands of hydraulic motors do you work on?
We regularly service Piusa, Char-Lynn, Eaton, Parker, and other common OEM motors, including the SAE A and SAE B flange styles found on most compact equipment.
Do I need to bring the whole machine in, or just the motor?
Just the motor is fine for most rebuild work. If diagnostics are needed to confirm the motor is actually the problem, we can talk through that over the phone at 515-292-2599 before you haul anything in.
