Kayaba: Kayaba Spare Parts, Replacement Parts and KYB Hydraulic Components

Kayaba, also known as KYB, makes gear pumps, piston pumps, motors and control valves for mini excavators, forklifts, tractors, loaders and other mobile machines. TSA Hydraulics Engineering supplies and cross references Kayaba parts within the Hydraulic OEMs group of our Brands range, alongside Parker, Linde, Danfoss, Kawasaki, Parker Hydraulic Pumps and Danfoss Hydraulic Pumps.

Gear pumps look simple, so they’re easy to mismatch. Rotation, shaft spline and port positions can vary even within one KYB series. We match on all of them, not just the size. A wrong rotation pump won’t build pressure. Send the KYB number for genuine or equivalent parts.

Kayaba Components We Match

Kayaba hydraulics are especially common on compact and mid size machines. The parts we match most often include:

Gear pumps: single- and multiple-section pumps for working hydraulics and steering.
Piston pumps: variable pumps for mini and midi excavators.
Travel motors: for compact excavators and tracked machines.
Control valves: sectional and mono block valves for working functions.
Cylinders and seal kits: for repairs and rebuilds.

Kayaba pumps on their own are covered in more depth on our Kayaba hydraulic pumps page.

Matching a Kayaba Part

KYB part numbers describe the series, displacement and options, while machine builders often add their own numbers on top. The best match comes from the KYB number on the part itself, plus photos of the shaft, flange and ports. For multiple section gear pumps, note the displacement of each section and which way the shaft turns, viewed from the shaft end. If the shaft is splined, count the teeth.

Compact Machines, Big Downtime

On a small machine, one failed pump or motor stops the whole job. Mini excavators and forklifts are often booked back to back, so a quick, accurate match matters as much as price. Equivalent gear pumps and travel motors are common for popular KYB models, and can be a practical option when the genuine part has a long lead time. Keeping a spare gear pump for your busiest machines can cost less than a lost week of hire.

Genuine, Superseded or Equivalent

Where a genuine Kayaba part is available, we’ll quote it. Older numbers may be superseded, and we’ll show you the current part and any differences. Where an equivalent suits better, we’ll say so plainly and explain how it compares on dimensions, ratings and fit.

Keeping KYB Hydraulics Running

Compact machines often run with small oil tanks, so oil heats up and gets dirty faster. Change filters and oil on schedule, keep breathers clean and check hoses for rubbing. Travel motors need the right gear oil in their final drives. A noisy gear pump usually means suction trouble or worn gears, and catching it early protects the rest of the system.

Related Hydraulic OEMs

Kayaba sits alongside other hydraulic OEMs in our range. Larger excavator pumps, regulators, and motors are covered under Kawasaki; mobile steering, orbital motors and valves under Danfoss; and dedicated Parker pumps under Parker hydraulic pumps.
