Well, he does have a NA golf cart. But it's fuel injected soooooo.You probably hate fuel injection and turbos too, fucking boomer.

Ripsaw driveline
- Thread starter WaterH
- Start date
I love turbos and fuel injection but I also love 100% driver input when it comes to the driving. I'm not saying computerized shit isn't faster I'm just saying that it was invented to give the slow guys an advantage. A good driver is a good driver with computers or without.
Like the engineers in Italy that design the equipment my company sells always tell me.....
"We have to make machine smarter and smarter every new generation because operator get stupider and stupier every generation."
He ain't lying....

and the target market for most vehicles is race car drivers?
I'm not ashamed to admit that computer intervention has saved my ass when I've run out of talent and I was glad to have it's help.
So the reason for starting this thread is in my back yard.
I would like to get it running. The stock driveline is a Detroit driving two verible hydro pumps that feed two verible hydro motors. The controls for those pumps/motors is gone. Not sure if any of that stuff is any good and the control technology is not available to buy Even if it did. All that hydro junk looks extremely expensive To rebuild. This will only be a toy, so not interested in spending more than 10K or there abouts.
The hydro motors drive big sprockets/chains inside the frame. The chain drives all the tires through swing arm suspension. I believe I could yank out the motor and all the hydro stuff. I have a 12 valve Cummins (bro) and I think I could source a tranny for a couple grand. That leaves building the ripsaw setup to drive the sprockets. I have a lathe/mill and can do basic machine shop stuff. The Howe stuff looks fairly easy to make. That’s why I’m interested.
If you guys got an easier idea, I’m all ears. (Remember the 10K budget.)
Okay, you really should have made this post as #1 or #2...
Keep what you have in there. Hydraulic controls are available everywhere, in this case find an old piece of industrial equipment with a blown engine and scavenge the controls from it. Or find surplus hydraulic control parts and piece the system together individually. Don't try to reinvent the wheel, countless skid/track steer things are driven by hydraulic controls. Both mechanical and electronic.

would the chain drives be up to the task of road speeds?

With 4 tires spinning I think that would be a instant chain break.
Depends on the chain. If it's open roller chain no. If it's oil bath hyvo chain then yes.
WaterH, do you have pictures or video of one of those is operational condition? What was it originally used for in the military, troop transport, missle carrier
or something else? It's odd....
Edit: Are those H1 size wheels & tires? If so, it's alot smaller than I was originally thinking it was. That's pretty bad ass.

And?
Speed is only a factor of gearing. That chassis will be a handful past 25 or 30 anyway.

If sized correctly sure.
I don't see it being an issue. Plenty of chain drives used in industry in more demanding situations.
Over the cab on earlier models, in a tube on the right side on later. Have one of each.

Probably not. That's a Vulcan Wheeled Carrier, which never actually made it into production or service. Only prototypes and test vehicles were made based on what I could find.

If you gonna spend the time to make it go might as well make it go fast.

Race between the Ripsaw and this beast? I want to hear that Detroit screaming...
They are, it's not nearly as big as it looks. I saw one complete with replica vulcan cannon a few years ago in the Dallas area, where I believe they were built. 8 wheel independent suspension with hydraulic over coil "shocks" with 12" of operator height adjustment. His is probably sitting at the lowest setting because hydraulics. IIRC it's chain from the motors to the top of each trailing arm and another chain inside the arm to the tire. Top speed in the 40s.
WaterH, please don't fuck that thing up by putting tracks on it, it'll be worse not better than tires. Plus the way that suspension works it probably has way too much articulation for tracks anyway. Get the drives figured out and worry about suspension control later.
I'd drive it.

Corrected for youI'd send it.
Lawn darting that thing would bring a whole new meaning to the phrase "eating your knees." You try first.

I always had that thought in the back of my mind driving HEMTTs. The only thing separating me from whatever I ran into would be the sheetmetal cab and a lightweight bumper. But they were also kinda sketchy over 45-50mph or so which helped keep speeds lower.
Any vehicle that uses the cab as a bumper is sketchy as fuck, I don't blame you for having that thought on your mind. Plus with a HEMTT, depending on how it's configured, there could potentially be an enormous amount of weight trying to squeeze the cab flat against the immovable object it comes into contact with. Momentum is a bitch.

Yeah... Our HEMTT tankers would be pushing 60k lb when fully loaded. And the brakes kinda sucked. Always fun.

I believe the hydraulics are all custom shit that I would have to either rebuild or replace with more common stuff. ($$)
I have no intention of fitting tracks, but the system is the same. The H & H setup could power the chain drive that is already there.
An auto trans for each side. Should be pretty simple, fab a bellhousing / chain case to power both.
That doesn’t sound simple to me at all.
The hydraulic controls on this thing are all proprietary patented stuff that is not available. It does not have simple hydro pumps or motors. From what little I know, driving fast vehicles with hydraulics is trouble.
It drove fast before with the chain drives, I’m just planning to swap the drive motors for a differential. The H & H setup looks like something I could make with my lathe/mill And junkyard parts.
Everyone, there are two giant chains in the box tube frame rails filled with oil. Each chains drives all the tires on that side. So it is a skid steer just like tracks. I’m not changing that.

oil filled chain drive, never considered that. are the drives to each wheel oil fill too?
i think ak250 sadi above it has 12" of ride height and 40mph. very cool rig

I have not opened the swing arm. I don’t even know if each one has a chain or gear driven. It has tons of selinoids that control the height of each wheel independently and grouped. So you can jack up each side or front and back like a Mexican low rider. When jacked up, it still has suspension. Standard Hummer wheels/tires. Disc brake on every wheel. I think it went faster than 40.

I don't think you realize how cheap modern hydro stuff is. Post specs of the OG system and we'll be able to help you find the shit you need.
I bet if you posted up some pictures of what you have left in there for hydraulics HYDRODYNAMIC and others may be able to point you in the right direction on getting it working without rethinking the entire drive system. Just because it has a bunch of complicated shit going on with that stuff doesn't mean basic forward, backward and steering functions like a wheeled bobcat won't be achievable keeping the plumbing simple at first.
What the fuck do you do with it if you get it running? Just seems like a bigger more useless version of an Argo 8x8 that everyone thinks is cool until they own one for 8 minutes.
