Continental Hydraulics HPV-6B35, HPV-10B35, HPV-15B35, HPV-20B35, HPV-29B30 Technical Manual

I’ve seen more hydraulic pumps come through my shop with stripped mounting bolts and wrong compensator settings than I care to count. Usually because somebody grabbed a third-party summary instead of the real thing. This Continental Hydraulics HPV-6B35, HPV-10B35, HPV-15B35, HPV-20B35, HPV-29B30 Technical Manual is what you need on your bench before you touch a single fitting. 51 pages of OEM data – no aftermarket reheat. You want the correct displacement for an HPV-20B35 at 1750 RPM? It’s in there. Need the continuous pressure rating for the HPV-29B30? Page 2. Don’t guess.

HPV Series Axial Piston Pumps: Index and Model Coverage

First thing I check in a manual is the index. This one lists every model with its continuous pressure, flange mounting, displacement, and theoretical flow. You get the full range: .88 cu in/rev (HPV-6B35), 1.26 (HPV-10B35), 2.09 (HPV-15B35), 2.62 (HPV-20B35), and 3.78 (HPV-29B30). Each model has dedicated pages for disassembly, reassembly, and control adjustments. The index also points to the pressure compensator section and accessory pages for the FPVR and AB pumps. No flipping through 200 pages of generic instructions.

General Specifications – Fluid and System Requirements

Oil specs matter more than most DIY guys realize. This manual tells you to use petroleum-based hydraulic fluids with rust inhibitors, anti-wear, anti-foam, and deaerating agents. Page 4 covers recommended fluids and viscosity ranges. If you’re running a non-standard fluid, you better cross-check the OEM recommendations here. I’ve seen pumps fail from using the wrong additive package – this manual will keep you away from that mistake.

Control Options: Pressure Compensation, Load Sensing, and Horsepower Limiting

The HPV series comes with several control codes. The manual details each one: standard pressure compensator (Code not specified but built into all models), remote pressure control (Code 7), load sensing control (Code 19), and horsepower limiting control (Code 26). Each section includes adjustment procedures and testing steps. For example, the horsepower limiting control allows you to tailor the pump to system demands – high pressure/low flow or vice versa. You need the exact tuning procedure, not a guess. This is where the OEM steps matter.

7 Systems Covered in One 51-Page Book

Displacement adjustment, flange mounting specs, SAE industrial mounting dimensions, maximum volume adjustment, pressure compensator adjustment, remote control hookup, and rebuild procedures. That’s seven distinct areas. The manual even includes the ANSI symbol for the variable displacement pressure compensated pump. If you’re troubleshooting a pump that’s not holding compensator set pressure, you go straight to the compensator section – no cross-referencing five different sources.

Why OEM Documentation Outruns Any Aftermarket Reprint

I’ve been handed aftermarket manuals that claim to cover this pump series but leave out the flange mounting details or the remote pressure control wiring. This is the real Continental Hydraulics factory technical manual. The original PDF is 51 pages, exact same content the OEM technicians use. No reprints, no redacted sections. When you’re rebuilding a pump that runs at 3500 PSI continuous, you don’t want “typical” values – you want the exact spec from the manufacturer. That’s what you get here.

Frequently Asked Questions

Does this manual cover the HPV-29D35 model?

No. The index lists HPV-6B35, HPV-10B35, HPV-15B35, HPV-20B35, and HPV-29B30. The HPV-29D35 is not included. Double-check your model tag before ordering.

Are torque values included for the mounting bolts?

Yes. The manual includes SAE flange mounting specifications and bolt torque data within the individual model sections. Page 2 gives the flange type (SAE A, B, or C) for each pump. You’ll find the torque values in the assembly procedures for each model.

Can I use this manual to rebuild a pump that has a stuck compensator spool?

It gives you the disassembly and assembly steps for the compensator and pump core. However, if the spool is seized, you may need additional cleaning or replacement parts. The manual won’t tell you how to unstuck a spool, but the OEM procedure will show you how to remove and inspect it safely.

Why should I buy this instead of a free PDF from a forum?

Free PDFs often have missing pages, blurred schematics, or incorrect torque tables because of scanning errors. This is the original OEM file – every page is legible, every spec matches the factory blueprint. When you’re working on a pump that costs thousands, saving twenty bucks on a manual that might be wrong is stupid.

You need the factory data to do this job right. I’ve been turning wrenches for twenty-eight years, and I can tell you the difference between a pump that runs five more years and one that starts leaking after a month is the quality of the information you follow. This manual gives you the OEM procedures, the correct tolerances, and the safety warnings that keep your fingers attached. Access the Factory Manual and get the job done the first time.
