If you own a New Holland excavator, the main hydraulic pump is the part you do not want to think about until you have to.
When it goes, the machine sits, and a sitting excavator at $5,000 a week of lost work makes everyone unhappy.
The good news is that pumps for the New Holland E-series are not the mystery they look like at first. Most of them are the same Kawasaki piston pump under different paint, and once you know how to read the OEM numbers, ordering a replacement gets a lot easier.
We sell aftermarket pumps that match the original specs across the full E-series catalog, and this guide is what we wish every customer knew before they called us.
Why most New Holland excavator pumps are Kawasaki K3V inside
New Holland Construction does not build its own main pumps for the mid and large excavator range. They source from Kawasaki Precision Machinery, the same supplier that builds main pumps for several other brands you would recognize.
The pump that sits behind the engine on an E215B, for example, is a Kawasaki K3V112DT or K3V112DTP. Cross-reference numbers like YN10V00036F1 and YN10V00036F4 print on the case, and those are what your dealer parts department is looking up when they quote you the OEM rebuild.
This matters because aftermarket pumps that match the Kawasaki spec, not just the New Holland part number, will install with the same ports, the same pilot connections, and the same flow characteristics as the unit that came out.
We have customers who have been running our pumps for three years on machines that work daily, and the units perform the same as the originals at a fraction of the price.
Decoding the New Holland E-series model names
The naming convention on these machines confuses a lot of buyers, especially used-equipment buyers who are trying to source parts for a machine they did not buy new.
Here is how the suffixes break down.
What "SR" actually means
SR stands for Short Radius. These are the reduced tail-swing models, designed to work close to walls and inside structures without the counterweight clipping things behind the operator.
From a pump standpoint the SR machines run the same Kawasaki pumps as their full-tail equivalents in most cases, but the hose routing is tighter, so install clearance matters. An E115SR and an E115 share pump specs but not always the same install kit.
B, BSR, and BSRNLC suffixes
The B is a generation marker. An E215B is the second-generation E215, with updated electronics and emissions hardware.
BSR is short-radius B-series, and BSRNLC is short-radius B-series with narrow upper structure (the NLC).
For pump compatibility, the B generation is the line that matters most, because earlier and later B variants sometimes use different pilot pressure settings even when the pump body is the same. Always confirm the OEM number on the pump itself, not just the model on the cab.
Pump-to-machine reference for common E-series models
Here is the rough mapping we use most often when customers call. This is not exhaustive, and we always verify the actual OEM number stamped on the pump before shipping, but it gets you in the right area.
Mini class - E15, E18B, E18SR, E27B, E27SR, E27BSR.
These run smaller Kawasaki K3SP-series pumps. Replacements in our catalog cover the full mini lineup with prices in the $3,000 to $3,500 range.
Mid-size - E115SR, E130, E135SR, E160.
Kawasaki K3V112 family. These are the workhorses of the lineup, and our aftermarket replacements run around $5,100 with same-day shipping.
Heavy - E175B, E200SR, E215, E215B, E235BSR, E235BSRNLC.
Larger displacement K3V variants, K5V series on some units. Pump pricing on this end of the catalog sits between $5,100 and $5,200 for our aftermarket units.
Our full New Holland hydraulic pumps catalog lists 146 part numbers covering the E-series and beyond, and the parts specialists can match a serial number to the right pump in a few minutes.
Finding the OEM number on the pump itself
Before you call us, climb up and find the data plate on your pump. It is usually on the side of the pump body, sometimes on top, and it lists two numbers:
- The Kawasaki model (K3V112DT, K3V112DTP, K5V140DTP, etc.)
- A New Holland or CNH part number that starts with YN, KSJ, or KRJ
Take a photo. The plate gets oily and the engraving wears down, so a clean photo from when you first inspected the machine is worth keeping.
If the plate is unreadable, the next best thing is the serial number of the machine. New Holland published parts catalogs that cross-reference serial ranges to pump assemblies, and we can pull the right unit from that. The CNH parts portal at mycnhistore.com has the official lookup if you want to verify before you order.
Replace the whole pump or rebuild what you have
This is the question we get every day. The honest answer depends on three things: how many hours are on the machine, what failed inside the pump, and what your shop labor rate is.
If the pump is leaking from the input shaft seal and there is no metal in the hydraulic filter, a seal kit and a careful tech can keep it running. We have customers who do this every two years on the same machine and it works.
If the pump is whining, losing pressure under load, or you found bearing material in the case drain, that is a different conversation. Rebuilding a K3V112 with full bearing and piston work runs about 60 to 70 percent of what a new aftermarket pump costs from us, and the rebuild does not come with a warranty unless your shop offers one. We do.
The other factor people forget is downtime. A rebuild takes a shop a week or more if they have to wait on parts. Our pumps ship same day from Buffalo or St. Catharines and arrive in two to five days continental.
If the machine is on a paying job, the math usually favors the new unit even when the rebuild looks cheaper on paper.
What to verify before ordering a replacement pump
Two quick checks save returns.
First, confirm the rotation. Most Kawasaki K3V pumps on New Holland machines are right-hand rotation viewed from the input shaft, but a small number of older units are not, and ordering the wrong one means the splines will eat themselves.
Second, confirm the regulator type. Some pumps come with a positive flow control regulator, others with negative flow control, and the controllers on the machine expect one specific signal pattern. The OEM number on the pump tells you which is which.
If you want us to confirm everything before you commit, send your machine model, the year, the serial number, and a photo of the pump data plate to our parts team at hydraulicamerica@gmail.com or call 1-844-232-0906.
We will match the right pump, ship it free anywhere in the continental US or Canada, and back it with our two-year unlimited-hour warranty. If the pump turns out not to be the problem after install, our 30-day return policy comes with no restocking fees, which is something most pump suppliers will not put in writing.
