Chief buggy

[gt1guy]

this seems pretty reasonable really. just holesaw out some uhmw pucks.

but I might be able to get 11'' with grinding stops and 1550...

Perfect. Get your max steering set and if you don't use up all 11", puck it.

 

[Bebop]

But I have no idea if that is open center or closed.

I can tell you right now it's not closed center.

I see what you mean by threads different. Equal pain if it goes ***s up out on a weekend.

When is the last time a ram went "***s up"?

Broken fittings is all I ever saw. So not really the ram.

But thanks for the idea. I think I will get two. We can machine down that flange and I just called. There is a second port. It’s in the third pic right above blue seal. Had to zoom in to see

 

[Bebop]

There is a second port.

I know, I even wrote that you needed to weld another fitting to said port.

 

[Sean]

also i see PSC will limit travel for $65 when ram is new.

They limit internally. Station on the old PBB used to give you aluminum spacers that were a tight fit....heat 'em up in the oven, throw 'em on the shaft just behind the clevis and they stay there....been running 1/2" spacers on my DE cylinder since 2006 like that. Jesse Haines said to do the same to limit my portal steering if I was going to use the last iteration of the RCV 50° joints on his boxes.

fair.

this is the orbital i have on the current buggy or at least the closest on the web. I wouldnt might know the size as i would love to got a bit faster someday

I mis understood.

Holly buckets. 2 rams. Shipping 262 to Iowa. Cheaper than any one ram I been looking at. Weld on ports are like 2 buck each. So thinking about cutting off the the other metric and put to SEA or NPT or whatever in its place. Thanks again for the idea.

That's a great idea.
If you're really limited in space you can weld a JIC fitting directly to it.
Only thing you'll have to do is tweak the clevises to fit the 22mm bolts on the end or get some 22mm heim joints (they exist).

Careful that 3" rams require a lot of fluid to move and will absolutely max your pump out if you're trying to go fast.

For sure. And thanks.

So would a 6gpm pro pump from radial feed them?

 

[pennsylvaniaboy]

I know it’s not a 3” but for giggles, what about this

2.542(65MM)x10.875(276MM)x1.259(30MM) Double Acting Double Rod Hydraulic Cylinder Spicer D7302463601 | Spicer | Brands | www.surpluscenter.com

 

[RadialDynamics]

so be prepared to go down a deep rabbit hole. one cant just use a pump from radial dynamics...

Sure one can, but the pump works even better with the complete system 😉

This seems debatable from the guys I have talked to that have used it and have used other systems, and find little change. The most important thing I have seen, is running a sealed system to allow pressure.

The vortex reservoir makes a bigger difference the higher the flow rate and more demanding the system is. However, all I will say is do not run a completely sealed reservoir. While some pressure in the tank is good, more than 15-20 psi is putting the shaft seal of the pump at risk of failure. A tank needs a means of pressure relief which is what our breather valves are intended to control. Otherwise with a sealed tank, there are too many variables to ensure that the tank pressure stays below the pump max inlet pressure.

 

[RadialDynamics]

So would a 6gpm pro pump from radial feed them?

Pump flow is really matched more to the orbital size than just the ram size. The larger the orbital displacement, the more flow you need to be able to turn the steering wheel at a normal rate. The 6 GPM pump works great with 200cc orbitals which would be 4 turns lock to lock on a 3x9 cylinder. A 250cc orbital (3.25 turns) works great on a crawler but for go fast is starting to reach the flow limits. While we don't advertise it much, we do offer the Pro Series TC with up to an 8 GPM regulated flow rate for racing applications with the larger orbitals but at that rate through a TC pump, reservoir setup becomes much more critical and we pretty much require a vortex reservoir for going that high of a flow.

It just depends what you want to do.
The latest CutlerFab buggy uses one and the owner is very happy with it.
Feeds dual 3" rams no problem.
But it's a crawler.

Nephews buggy is a crawler with rear steer. Hence the 3” ram’s. Not too sure on how well it would do on go fast. So you might consider that as Bebop is suggesting.

 

[pennsylvaniaboy]

So in reading all this, I think my plan is as follows-

2.5x10 Surplus center ram
200ml orbital- Bigshocks.com
PSC clevis and tie rods
6gpm Pro pump and 4.5" pulley from radial dynamics

I plan to make my own reservoir, but will see when the time comes. I want to fit the cooling stack etc first.

As to the cooler, I am running this on 2 rigs with success.

[Bebop]

Yeah that's a big cooler you'll be completely fine with that

 

[pennsylvaniaboy]

the rest of the plan seem kosher too?

 

[Bebop]

Oh yeah.
As far as reservoir goes IDK if you're going to save a lot by building one yourself but why not.
I'd also add a filter, but that's just me.

well for the reservoir, I built my own last time.

$30 fill cap, $15 in pipe caps, $10 in an fittings and some 4" exhaust tubing. Make the reservoir whatever height you want.

 

[pennsylvaniaboy]

So also starting to get close to needing 2.5"x16" air shocks. In looking, there are lots of brands- fox, king, ads, radflo, JHF, etc...Then even foreign options...

Who is the best to use, and why? Currently leaning torwards ADS, and Radflo.

 

[SteerAndStuff]

I started with 2.5 standard radflo and swayaway shocks and swapped to JHF Radflo bypass and well worth the upgrade.

Yeah, for the price, the JHF's make sense for this type of lightweight application.

4312-JMX Double Ended Ram Tie Rod Kit, FK JMX PREMIUM ROD ENDS​

https://goatbuilt.com/product/4312-jmx-double-ended-ram-tie-rod-kit-fk-jmx-premium-rod-ends/

So this kit with the premium hiems is $250 shipped to me.

But it doesn't seem like to many use these compared to the PSC ones.. which are $300 shipped.

PSC style for reference..

 

[SteerAndStuff]

I used the goat built with fk rod ends on my buggy. With rod ends straight into cylinder rod it allows for longer tie rods and thus less angular movement thru stroke range. Slightly.....

It also seems more compact...

 

[pennsylvaniaboy]

Well I got some parts in,

Ordered 1550 stock shafts, the PSC clevis and tie rod kit from Summitracing. Super clean parts, I will convert the 1550 shafts to full circle clips before final install.

I also ordered up a Surplus center 2.5x10 double ended ram. As with all things, this seemed like the best compromise for price, function, and fit.

 

[pennsylvaniaboy]

I will add some more parts goodies later but this is a mockup of steering. Ram will mount on a plate that will bridge the front bash bar, and a bar that will span the link tower to the pumpkin of the top hat. Should be light be effective. The bash bar will be 2” x.25 wall.
