You've seen our hydraulic combo kits around for years, and we're now proud to offer our own line of reliable, easy-starting gasoline engines as part of the combos.  We've tested these engines against Kohler, Briggs & Stratton and a handful of other makes, and have proven ours to be just as reliable in all conditions, AND better starting in the DEEP COLD that can sometimes come with wood splitting activities. Of course, they run just as well in the heat for those that prepare for the winter well in advance! They seem to always start right up, even when we've left old gas in them for a year! (not that you should ever do that!).  


We have many varieties of these kits and components, so if you don't see exactly what you want, search our other listings or feel free to contact us!

  1. 16 GPM Commercial Duty 2-Stage Hydraulic Pump for Log Splitters


  • New Hydraulic Log Splitter Pump 16 GPM @ 3600RPM
  • Model # GP-CBN-160
  • Shaft: ½”
  • Inlet port: 1”
  • Outlet port: ½”
  • 7- 1/4" L with shaft
  • 5- 5/8” L without shaft
  • 3” across body
  • 3 -3/8” across mounting surface
  • Minimum 8 HP or larger gas engine, direct drive only, horizontal shaft (can be mounted vertical or horizontal)
  • For use with open center hydraulic systems only
  • First Stage: 13 GPM @ 650 PSI
  • Second Stage: 3 GPM @ 2500 PSI
  • Maximum pressure: 4000 PSI
  • Bolt circle: 2.83in.
  • 4 holes spaced 2” on center
  • Mounting hole diameter: .344in.
  • Woodruff key: 1/8in.
  • Rotation is clockwise
  • Flow rates on the hi-low tandem pumps are 0.256 cu in/rev on the low flow and 0.793 cu in/rev on the high flow pump.
  • This 2 stage pump can give you much faster cycle times and higher possible pressures with a small engine. Excellent for use on log splitters. 85% efficient.
  • Model GP-CBN is a HI/LO hydraulic gear pump with 12 different displacement combinations with maximum pressures of 900 psi for the low pressure pump and 3000 psi for the high pressure. The change from LO to HI pressure is automatic with the LO side pressure pre set from 400 psi to 900 psi.
  • The HI/LO section of the pump is all aluminum and the end plates are cast steel. Applications for the HI/LO pump are log splitters, presses etc where rapid movement of the cylinder at low pressure is required prior to automatically switching to the high pressure mode to meet load requirements.


  1. Auto-Return "A7" Detent Valve w/Adjustable Detent


This is the next generation in log splitter valves. The detent is usually what wears out and causes valves to fail. This valve allows user to adjust the kick out pressure to what they need and as detent balls and grooves wear.

  -  Single spool, Open center

  -  Max pressure rating: 3500psi.
  -  Relief valve set at 3100psi but is adjustable.

  -  Working ports ½” NPT

  -  In/Out ports ¾” NPT

  -  Detent Pressure set at 700 psi but is adjustable.

  -  Compatible with most splitters (SpeeCo, MTD, Brave, Swisher etc) in addition to working with this kit.

  -  Threaded end cap for easy detent adjustment (most valve "failures" are just tired detent mechanisms - with this valve, you can adjust the detent when the mechanism gets tired - then you're back to brand-new-spec operation!)

  -  Mounting bracket holes (4) are 5/16-18 thread pitch and are spaced 1" x 2-5/8" apart
