Busted hydraulics on my Hinomoto -- Toast?

[qualityhardware]

My hydraulics went out on my Hino e264. The 3PH was holding a box blade, I was lifting it up and the whole thing started to shake and shudder.

Then it just lowered and has stayed there ever since.

I drained all of the fluid out of the transmission and opened up the suction lines.

There was a LOT of debris in the oil and there was no filter screen coming out of the transmission housing into the suction lines, so whatever gunk was in there is now in the hydraulic system.

I poured 5gal. of kerosene into the transmission and ran the engine for 10 minutes. Tried working the hydraulics again and got nothing.

Refilled the system with hydraulic oil and still nothing.

This leads me to believe that the control valve is broken and pump is probably damaged.

My question is; Do I have a hope in Hades of finding replacement parts for this?

Thanks.

Yes you can find replacement parts but you'll have to know what you need first. Have you changed the filter? Hinomoto's don't have the screen like Yanmars do.

Well,

I pulled the control valve and gave it a good cleaning. The relief valve contained two pieces of three pieces of a lock washer that somehow got sucked into the system.

The lift on the 3ph goes up about halfway now and works pretty well, which tells me there is something not right with the pump. Possibly piece number three is in there with a damaged a piston or cylinder wall.

Was able to secure a new pump unit from RCO tractor. Will post with result of that installation.
