Hydro Assist - Do I need another reservoir?

[davido]

Another thing I thought about today when getting the hydro-assist mounted up (after only about 3 years of owning it).

Do I need a remote reservoir to carry more fluid?

Remember, I have hydro boost brakes also. If my power steering pump dies, I'm fubar'd. :(

[stx4wheeler]

you dont have to have one, but i recomend a power steering cooler, this will allow for some more fluid and keep it nice and cool. now i just need to put my cooler in.

[Sharpe]

Depending on what reservoir you currently have, you can bootyfab some more fluid capacity to it by slipping a piece of radiator hose over the neck of the reservoir, and cuting the neck off another reservoir to put at the top of the hose. Ghetto, but quite a few chevy people have done it with no problems.

[J Cooper]

maybe use an external resevoir like on a toyota... just kinda going in line with your low volume side for extra storage.

[davido]

Does the filler of a remote one have to be the same height as the stock one, or does it matter?

[J Cooper]

i think it has to be the same or higher.. it depends... which ever one has the over flow deal on top i guess would have to be higher... like i know the GM ones have a little seap hole on top... i dont think the toyota one does...

i have a toyota one here in a box at the house if you need one for the trip... i was thinking about using it on the jeep when ever i do my stuff.. but you could use it or buy it if you want it

[CRaSHnBuRN]

the toyota one is kinda sealed, but will still spray out if overfilled, so I would definitely try to keep them at the same height if possible. Or would it be possible to seal one, like the chevy one and mount the toyota one higher and just fill from there? BTW, the toyota reservoir will need a 1/4in ID hose on the inlet, and a 5/8 ID hose on the outlet

The problem I'm having with my toyota one is the volume of the ram (6x1.5) is nearly 2/3 of the reservoir, so when the ram is extended, the reservoir is nearly empty, and when the ram is compressed, it blows any excess fluid out through the cap. I'm hoping to combat this by adding a oil filter inline to hold more fluid in the system, and later adding a bigger reservior.

[tigweld]

i doubt the cooler and filter will solve your problem, u need the extra reservoir volume to deal with the volume change not increased oil capacity. you need a place for the oil to go when the ram is compressed, not more oil.

[uglyota]

I've tried to explain this 30 or 40 times but it doesn't seem to be sinking in.

[CRaSHnBuRN]

yes it does, but until I find a larger reservoir that fits in the little area I have, I got to make do with what I have. Every reservoir I've found so far is to tall, or lacks the added volume I need. As for the filter system, I already have everything to plumb it in, and had it all back when I first did the hydro assist, so I'm not out anything to run it. When I can find something larger, that will fit, then I will make the necesary changes, but right now I'm just gonna have to band aid it

one more time please

[CRaSHnBuRN]

remember when I asked about building a reservior? I knew it was a problem back then, and was searching for solutions, but so far I haven't found one. The closest thing I have found was a horizontal tank from speedway motors, but so far they haven't been able to give me any decent specs on it, and until I know if its is large enough to be worthwile, I'm not gonna spend the cash on it

[BMFScout]

I think Fred has one of the 6" ones.

[CRaSHnBuRN]

I need to keep it under 5 inches total, including where the hose connects tp the bottom and then goes to the pump. If I go more than this, it will either stick up past the hood and be unprotected (and look like ****), or it will make it next to impossible to operate the free spool lever on my winch. Any other place I attempt to move it to will have interference problems with something. What I really need is a horizontal tank with about a 3.5-4 inch diameter

or you could get one off of a camaro, but the mounting is a bit wierd.

[CRaSHnBuRN]

Okay, I'm confused? How is a nitrous tank gonna help?

as for the camaro idea, do you have any pics or specs. I can make do with wierd mounts, if I can fit it and increase the capacity

[agjohn02]

fixed the link. i was looking for a cheaper plastic one. iirc, you can drill the $15 ones out to 3/8".

this guy thinks you can use PVC, but then again, he drives a Neon

A couple of more times Eric, I'm almost there. :) One question on the volume change, since it's pumping it into the other side of the ram, is there really that much volume change? It's not in and out of the ram, it's really one side to the other. At least from what I can tell. But then again, I've only had it bolted up about an hour and I haven't yet gotten to play with it.

[CRaSHnBuRN]

I was curious about the pvc idea. It seemed like it would work, be easy to seal, and cheap. If it didn't work I wouldn't be out much money. The only thing was how to allow the system to breath without it leaking? A rollover valve perhaps, or would something like this work http://www.surpluscenter.com/item.asp?UID=2005121213001554&item=9-4195-8&catname=hydraulic

Will those work for power steering fluid? I sure could use one for my radiator overflow.

[redcagepatrol]

You need a reservoir if you are using a single ended ram because one direction (the side without the shaft) will require much more fluid than the other. If you are using a double ended ram, you will not NEED the reservoir but it is recomended to help with keeping the fluid cool etc...

The fluid level should move from full to midway depending on which way you are turning with a single ended ram.

[uglyota]

A couple of more times Eric, I'm almost there. :)
I was actually referring to Chris, BTW. you and I haven't talked hydro have we?

Chris, what is the diameter of the yota reservoir? I think it'd be cool if you could have someone tig a piece of exhaust tubing or something in to enlarge the stock one

that's right but on one side of the a single ended ram u have the rod that is taking up some of the volume on that side of the system. I think if you calculated the amount of volume the rod takes up in the cylinder you could increase your reservoir capacity by only that much and good to go, but having plenty of capacity for extra fluid is never a bad thing

Exactly :gigem:

PS, I just went to Royal Purple Synthetic PS Fluid

[davido]

Ah, that makes sense. Thanks for the description.

[Shaggy]

let us know what works on this... i might need to do something like this with mine

[Fredo]

Yeah, I've got that PSC 6" remote reservior for hydroboost and the 1405 series pump. I had that done, combined with my steering box being rebuilt, ported, and tapped for hydraulic assist. I went ahead and got it setup for the hydroboost and got the box tapped to plan for the future. So with the large tranny cooler I have as a power steering cooler, and the almost 2 quart capacity of the steering system, it is definitely a damn good working and cool running system. I can't Imagine how much it would hold if I had the ram and the hydroboost installed and plumbed.

[davido]

What are you waiting for? Hurry up and plumb it up so you can make all necessary adjustments and advise me to the nearest possible solution as to make my life easier. :D

Chris, what is the diameter of the yota reservoir? I think it'd be cool if you could have someone tig a piece of exhaust tubing or something in to enlarge the stock one

somewhere beween 3 to 3.5 inches I think. Yes, tiging a piece of tube in will work, and has been done before, but once again, it is to long. The stock toyoa reservoir just barely fits as it is. As for other options for remote reservoirs, I've heard that some old mazdas had a fairly large reservoir

[davido]

Well my front end is completedly torn apart now. I'm going to see if I can talk my girlfriend into making a Hutto run sometime tomorrow:

http://www.4wdfactory.com/product_info.php?products_id=52
http://www.4wdfactory.com/product_info.php?products_id=29

Should I just give up and get one of these also?

http://www.4wdfactory.com/product_info.php?manufacturers_id=15&products_id=31

My inner J2O doesn't want to, but it seems to be the best option.

Before I tore my front end off, I did however get to drive it around the block a few times with the hydro assist. Cool stuff. It turns as good as my Dmax at rest, but as I let off the gas to go into turns, it slows a bit. Steering also nearly disappears when I brake but I'm not totally sure it was really any better before. I'll have to see how it does on the trail. I think idling it up may help a bit. It also doesn't look like fluid volume is going to be a huge issue though. Again, I guess we'll see.

[Doug Krebs]

Any Idea on where to get those fancy caps they have? There is plenty of aluminum tube laying around the machine shop...

[Cajun]

I <3 unintentional humor. :flipoff2:

[CRaSHnBuRN]

and thats the diameter ***** :flipoff2:
