Budget Full Hydro
« on: November 27, 2014, 05:44:47 PM »
Just read through part of Matt's build and found this:



Also found a post from Gif with a deleted spreadsheet I'm assuming was used for matching orbital/ram displacements. Gif, can you post this again?

Do you guys have any links to info on all the different types of orbitals? Load reactive, load sensing, etc. I'm thinking it's not safe to assume I want the same orbital as Matt. Looking to do something to Troy/571 originally/Jeff/Erik's CJ.

Will a hot rodded stock pump or something more HD like a WJ pump feed a single ended 8" ram

End goal will be easily steering 39" Reds. Occasional street use (no inspection here, not looking to start that debate)

Thanks guys

i used the stock pump on the i6 in the mj, worked just fine
used the stock pressure line and cut it ,smike gave me a high pressure compression fitting to attach to a hose

Stock pumps on 571 and 572. No hot rodding as far as I'm aware. Stock hydroboost pumps on both?

What about orbital types? What will I want for this application? PSC says they only sell load reactive. They have two different options, I put the cheaper in my cart below but have no idea what the difference is.

Also says the number of turns lock to lock is determined by dividing cylinder fluid volume by orbital volume. Makes sense. How is cylinder volume calculated? Simple as 2.5"dia x 8" length or does shaft size come into account?

Parts from PSC single ended ram kit, minus pump, res, and ram. Ram w same dimensions from Surplus Center. Can I get the lines cheaper? I'm assuming I'm stuck with their orbital to shaft adapter thingy.

My advice from piecing together hydro...buy the double ended full hydro kit from trail gear for $900 and be done with it.

My biggest reason for going single ended is space. Not excited about welding a shovel to the front of my axle. Hoping it might fit right where my assist ram is now.

Is there enough room to mount it high and incorporate angled skid?

I guess that's what I'm trying to avoid doing. Lots of options for mounting single ended high that won't require skid with drag link out of the way

Silly to focus on single ended when DE can be had so cheap.

On SE the Ram displaces fluid on one side only. Different steering speed each way.

Is double ended that much better? Worth fighting with the packaging to have over single ended?

No.

SE is fine for trail rig.

I run a stock pump / SE  2.5X10" cylinder / char lynn steering valve on my buggy.

SE is fine for a trail rig but I'd REALLY prefer double ended on the street myself. The wheel slowly turning all the way around with small steering corrections and corners would get to me.

Thanks Gif!

smike gave me a high pressure compression fitting to attach to a hose

Does anyone have info on this? Similar to the ends that come on the PSC DIY hoses kits? Didn't see anything that looked right on Surplus Center.

I am planning to ditch the stock steering wheel if I go the single ended route for that reason. I know even Dan's DE setup still ends up wonky though.

Screenshots for reference later. Will probably end up putting assist back together and selling as a kit when I can and use proceeds towards this stuff. Should be under $600 for everything with Dan's PSC discount.
