Rexroth Dual-variable Plunger Pump AP2D-12/14/18/21/25/28/36/38/42 PUMP Spare Parts For Repair Maintain

Complete Rebuild Kit for Uchida AP2D Series Pumps If you're wrenching on mini excavators, you know the Uchida AP2D pump is everywhere. These little pumps are tough, but when they finally give out, a lot of shops just swap the whole unit because finding the right internal parts is a hassle. We built this kit to change that. This comprehensive internal kit is designed to fit the entire AP2D family—covering everything from the small AP2D12 up to the AP2D42. Instead of piecing together parts from different suppliers, you get everything in one box: the Cylinder Block, Valve Plate, 10 Pistons, Retainer Plate, Ball Guide, Thrust Plate, Drive Shaft, Swash Plate, and 2 Servo Spacers. We know that in a busy repair shop, downtime is money. That’s why we don't just throw parts in a box and ship them out. Every single component here is measured and tested to ensure a true 1:1 fit with the original Uchida specs. If you’ve dealt with cheap aftermarket kits that leak or wear out in a few weeks, you know how important that is. Our parts are heat-treated and built to last, keeping your customers' machines on the job site. Are you a parts distributor looking to build your own brand? We can help. We offer full OEM/ODM customization—laser-marking your logo on the metal parts, providing custom packaging, and helping you stand out in a crowded market. Got an AP2D core on the bench right now? Drop us a message with the exact model number you're working on, and we’ll get a quote and shipping time out to you right away.

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.

Other brands too. Komatsu HPV, Hitachi HPV, CAT SBS, Kawasaki K3V, Sauer SPV, Linde HPR, Parker F11, Eaton PVH, Nachi PVD, Kayaba PSVD, Yuken, Liebherr LPVD, Toshiba PVB, Oilgear PVK, Denison PV6. Plus Doosan, Volvo, Hyundai, Foton, Kato.

Send us your pump model, we'll quote you fast.
