Wet Kit requirements

I know they make one with an onan motor and one with a Honda and onan is a lot better ! But I think it’s about $800 more

 

On our first truck and trailer (Ford LNT9000, Trailking hydraulic beavertail) we built our own pony hydraulic unit. Used a 30 or so gallon tank, honda GX160 motor, and a hydraulic pump we had from some obsolete equipment.

I sold it since, the pictures are here:

The good news is that worked. The bad news is that it had some sticky points. Number one is that it was hard to start in cold weather. Believe it or not, our solution was to cover it with tarp and run a exhaust hose from the truck exhaust under the tarp to warm it evenly. It worked well but was ridiculous.

What I know is that pressure matters, but the flow does not really matter. Pressure is force, and flow is speed. So, more flow, faster movements and less flow., slower movements.

I agree that a wet kit is the way to go. Much more reliable than a pony motor. And more power.

 

Most trailers run on 2500 psi, which is pretty standard in the industry. The gpm just depends on how fast you want the trailer to operate. Around 12 gpm will be plenty fast enough.

For what it's worth, I despise pony motors. Just another engine to upkeep and it seems like you run out of gas at the worst time, and another battery to have to deal with.

 

If the lowboy sets for any length of time, make sure you treat the gas.

 

I do this every time, it makes all the difference in the world.

 

I totally agree on shutting off the gas and running out of gas in the carb, it solves 99% of problems.
