Hydraulic Component ID - Cross Mfg.

[LodiCal]

What kind of hydraulic component is this; correct name so I can figure out what it does. Thank you.

For your Kangaroo? I don’t think the top reservoir with the bleeder is a Cross part. It is screwed into Cross valve? it looks like. More pictures of the valve would help.
What is your question for identifying the component? What is it doing/not doing?

Thank you for the reply TractorTech. Yes, for the Kangaroo.

The controls on the footplate of the boom and not working and I presume are not receiving hydraulic fluid

The levers labeled 1 and 2 move their respective components and are attached/adjacent to the tank/reservoir.

The red circles are the component in question. They connect to small hydraulic lines that are plumbed to the foot plate that lift and lower the boom and also power the hydraulic motors that power the tires.

X - slave cylinders that are currently stuck - [hat tip to Harry in Ky for slave cylinder ID].

1 - raises and lowers the lift
2 - forward and reverse.

Arrows point to what I believe are 3-way control valves; with number 1, when lever is depressed, just appears to release hydraulic pressure and the lift goes down and number 2, powers the motors to move the lift forward or back.

Another issue is represented by the last/bottom four photos. There is a lever on the basket that goes up and down that is frozen/stuck. The 1/4" rod is bent which I suspect was an issue sometime long before based on paint and stress marks etc.

First item. Those are fabricated oil chambers to operate the valve. Instead of a lever, the fabricated chamber is fed oil to push the valve spool down. I believe the valve is the same as the ones on the front; Cross BC valves with power beyond ports and adjustable relief.

Make that a CV or Converta valve:

By the way, the Cross part number, 1V####, is going to be on the bottom side of the valve that is bolted to the plate.

The lever that is frozen looks like a safety lock. You need to show what it is controlling and follow the hydraulic lines

"Those are fabricated oil chambers to operate the valve. Instead of a lever, the fabricated chamber is fed oil to push the valve spool down."

That makes total sense and now seems rather obvious. Thank you for explaining what was probably evident to everyone but me and additionally, thank you for the research. Now that I have an idea of what most of the components are, I will set about creating a crude schematic and try and figure out how everything is connected together.

In regard to the frozen lever, I somewhat expect/guess that I will find that it controls the flow of hydraulic fluid to the "custom" hydraulic valve under the basket footplate.

I will report what I find and fix etc. Thank you again Tractor Tech.
