Installed hydraulic wet kit on my semi truck

I have a hydraulic powered "beaver tail low boy" semi trailer. To run it, 3 years ago we built a hydraulic unit by adapting an electric power unit to run from a Honda GX-160 gasoline motor. It always worked, but was hard to start in winter and slow, due to small amount of flow.

So, I decided to install a wet kit to run the hydraulics off the truck itself.

So, now, everything is done. What this kit is, is a hydraulic power source that is fed from a PTO (Power Take Off), that is bolted to the transmission.

The kit has a PTO, pump that bolts to a PTO, a hydraulic tank, pressure relief, and hoses. I reused a tank from some old electric hydraulic unit, but we had to modify it to adapt it to outdoor use to prevent water ingress.

With this wet kit, everything is so much easier now. Everything is ready to be used the moment the truck is running. It has about twice the power of the old gasoline unit, even when the truck's engine is at idle.

The problem that I posted 2 days ago, with the pressure relief, was solved by buying another pressure relief.

Cool. How does the PTO work? Was the transmission built for a PTO option?

The PTO is a small gearbox. The transmission has a cover that can be removed, and a PTO bolted in its place. There is a gear in the PTO that corresponds to a gear in the transmission, and they mesh together when the PTO is installed.

There is a actuator inside that connects that gear with the output when air is supplied to this actuator. It is an air cylinder that makes two gears mesh. You use a pneumatic switch to supply air and actuate that cylinder.

The hydraulic pump bolts to the output of the PTO.
