Hydraulics Services
Hydraulic failure means lost time and profit. We provide expert diagnostics and repairs that restore full pressure, smooth function, and safe operation for your truck or equipment.
Hydraulic Diagnostics in Grand Rapids, MI
From liftgates to booms and auxiliary attachments, hydraulic systems power critical functions across a wide range of trucks and heavy equipment. Our hydraulic services focus on restoring performance, pressure, and leak-free operation—fast.
We service truck-mounted and standalone hydraulic systems, including:
- Hydraulic cylinders (single/double acting)
- PTO pumps and wet kits
- Control valves and spool blocks
- Hydraulic tanks, lines, and quick couplers
- Hose assemblies and fittings
Whether your dump bed is slow to rise, your crane is leaking fluid, or your plow won’t respond to control inputs, we identify the failure source and complete the repair using OEM-grade or high-performance aftermarket components.
Our team pressure-tests cylinders, inspects for internal scoring, replaces seals and fittings, and ensures every line and valve operates as intended under load.
Hydraulic Leak Repair, Rebuilds, and Hose Replacement
Hydraulic system issues can range from simple leaks to full system failures. We begin every job with a visual inspection and pressure test, followed by a targeted diagnosis of worn or contaminated components.
Common services include:
- Resealing leaky rams and cylinders
- Replacing damaged or burst hoses
- Diagnosing and replacing worn PTO pumps
- Servicing stuck or bypassing control valves
- Flushing contaminated fluid systems
All hose assemblies are custom-cut and crimped in-house to match OEM specs. We ensure compatibility with both high- and low-pressure systems and offer upgrades for increased wear resistance or temperature tolerance when needed.
With our experience in commercial truck hydraulics, mobile equipment, and construction attachments, we get your system operating smoothly, safely, and efficiently.

Common causes include worn seals, contaminated fluid, internal scoring, bent rods, or over-extension. Preventive maintenance and proper pressure regulation help extend component life.
What’s The Difference Between A PTO Wet Kit And A Hydraulic Pump?
A PTO wet kit refers to a truck-mounted hydraulic system powered by a power take-off. Hydraulic pumps are the component that creates flow and pressure within the system. Wet kits include tanks, hoses, valves, and the pump itself.
How Do You Diagnose Hydraulic Leaks?
Leaks are diagnosed by pressurizing the system and inspecting cylinder rods, hose connections, fittings, and valve seals. Dye tracing or pressure gauges may also be used to isolate internal bypass or cracks.
