New Video – Hydraulics Log Splitter Valve

This our first in a series of short video installments to highlight & educate our audience on some of the basic features of hydraulic components. Today’s topic is the hydraulic log splitter valve. This video points out the port locations and the log splitter valve adjustment points.

Remember, if you are looking for how to adjust a log splitter valve, it’s clockwise to increase pressure, counter clockwise to decrease.

How to Wire a Dump Trailer Remote

Knowing how to wire a dump trailer remote can be a little confusing, but just relax, we are here to help!

The first thing to consider: Are you wiring a Power-Up/Power-Down (Double-Acting) or Power-Up/Gravity-Down (Single-Acting) hydraulic pump.

Dump Trailers with Power-Up/Power-Down Pump:

Usually, these units use a 4-Wire remote, unless you have an older Homesteader trailer, or wiring any pump with 2 “Starter Solenoids”. If that’s the case, you can still use the 4 wire remote, you’ll not use the “Master” wire. The 4-wire remote has a wire that is “hot” with each button, one for the lift valve and another for the lowering valve, plus it has the “master” wire that is hot with either button.

Wiring is as follows:
-Green – Power (to Battery)
-Red – Raise (to Lift Valve)
-White – Down (to Lowering Valve)
-Black – Start Master (to Starter)


Trailers with Power-Up/Gravity-Down Pumps:

These units are a bit more simple, so you just have the power, starter & lowering circuits. These pumps lift when the motor starts and lower when the lowering valve is fired.

Wiring is as follows (See diagram for details):

-Green – Power (to Battery)
-White – Down (to Lowering Valve)
-Black – Start (to Starter)


Thanks for tuning in to this installment and we hope you learned something!

Hydraulics 101: What is the Stroke of a Hydraulic Cylinder?

Welcome to the 2nd installment of Hydraulics 101! So what is the stroke of a hydraulic cylinder?

hydraulic cylinder strokeThe stroke is one of the more commonly confused terms when it comes to hydraulic cylinders. The stroke is actually the distance the cylinder can travel, from fully closed to fully open. When someone is talking about a 30″ cylinder, they aren’t (or shouldn’t be) talking about the overall length of the cylinder, but they should be talking about how far it will lift or move something. The basic description of any cylinder is BORE & STROKE, so a 2.5 X 30 hydraulic cylinder has a 30″ stroke, meaning it will lift or push something 30″.

If you aren’t sure what the stroke of your cylinder is, subtract the length “fully closed” from the length “fully open”. Easy enough?
