The Uchida AP2D series is a compact axial piston pump designed for open-circuit mobile hydraulic applications. It is widely used in compact excavators, skid steer loaders, and mini construction equipment that requires reliable performance in tight spaces.
We supply complete AP2D series pumps and individual replacement parts. The internal repair kit contains 9 core components: cylinder block, valve plate, 10 pistons, retainer plate, ball guide, thrust plate, drive shaft, swash plate, and 2 servo spacers.
Each component is manufactured to OEM specifications. Cylinder block bores are precision-honed, valve plates are lapped for a tight sealing surface, and pistons are heat-treated for wear resistance. Available for fast shipment worldwide, with custom OEM/ODM packaging and private-label support.

Uchida AP2D Series Compact Pumps
I've rebuilt a lot of these things. The AP2D is the compact pump you see on mini excavators, skid steer loaders, small construction equipment. It's a Uchida design, built to fit in tight spaces where a full-size pump won't go.
When it starts whining, or the pressure drops off, you know it's on its way out. Most shops just rebuild it. New OEM costs a fortune, and there's no guarantee it lasts longer.
We make the rebuild parts. Cylinder block, valve plate, pistons, retainer plate, ball guide, thrust plate, drive shaft, swash plate, servo spacers. Seals and gaskets you can get anywhere cheap - we skip those. The expensive stuff that actually determines pump life, that's what we make.
Size range from 12 to 42 cc/rev. Covers everything from mini excavators up to small construction equipment.
Every part matches original Uchida specs. Bores honed. Valve plates lapped. Pistons heat-treated. Checked before shipping.
We stock parts for most brands, not just Uchida. Rexroth - A4VSO, A4VG, A4VTG, A10VSO, A10VO, A11VO, A15VSO, A20VO, A8VO, plus bent-axis stuff like A2F, A2FO, A7V, A7VO, A6VM, A2FM.
