Psc install

[jeffj]

I just installed a hydro assist on my 2012 with the high flow kit. My caster is set at 3.2 which didn't seem to bad before but with the psc it seems to steer quick. Is it my caster or do I just need to get use to it sense I've only driven it twice.

Even with my set up, my steering is quick with the PSC ram assist. It took one or two days to adjust to it. But having "flighty" steering is very different than the quick steering from the PSC. Flighty steering (too much caster) is much harder to control, it's almost as though any steering input is overcorrection to the extreme. Give it a couple of days to try and learn the ram assist system, you should learn to be able to drive it in no time.

It takes a while to get used to the new feel of your steering. It helps to not hold on to the steering wheel to tight. You need to have a loose grip.

Thats the hydro. Once you get used to it, its nice!

 

[jeffj]

Thanks for the input. I can't wait to get some miles under my belt and get it on the trails. I did have it on the interstate and it felt really good at highway speed. Just the back roads of WV got my attention.

I have about 5 days in and I can say it really is a sweet setup. Still playing with getting the ESP to stay off. Is it more sensitive with the psc? I don't think I had this much trouble getting the steering wheel straight before. I'm close but it kicks on about 2 times when I'm having fun pushing it through the turns.

I've had my ESP turned off since day one :cheesy:

I can't get mine to stay off on the 2012's. PIA

I really would like steering assist before the summer, but it seems there are still a lot of issues with the 2012. :thinking:

Talk me into it people. :cheesy:

It is a really sweet set up. You run 37's so you know how the stock steering sucks. Once I got used to it on the roads I can really push it in the turns like before. I've only messed with my steering a couple of times so I think I'm going to be able to get it right. It only comes on when I push it hard in the turns. Slow speed turning is just unreal. And I can only imagine how it will be on the trails.

Mike, I only have about 20 miles in, but I constantly have to remind myself I am driving on 37" tires. The steering is effortless; really great. As Greg said, it is not flighty in that there is no direction change going over bumps. But it is more sensitive; it takes very little effort to turn the steering wheel, which is of course exactly what it is designed to do. The main disadvantage associated with 2012+ is finding a place to mount the reservoir, but others have reported that the stock reservoir works ok if you want to go that route.

I too have the ESC light on, but that might be other issues, like a bad speed sensor.

Just wait until the issues go away. Installed a new pump two days ago it quit running in less than a block!

Dave has that been your second pump? I know you had your system on when you were back east. Have you had any other issues?

Dave, Jeff (all the others following along too) I have installed two pumps over the course of a few years. The last one was at Silver Lake Michigan during last years JKX in the parking lot of the hotel. I am guessing you guys are not running steering coolers? Honestly, I don't know of anyone who has not burned up at least one pump during ownership of a rig with ram assist. Even on my old tube buggie with full hydraulic ram set-up and pretty massive coolers, steering pumps being burned up were fairly common. At King of the Hammers, steering set-ups getting cooked are a big reason for race cars having a DNF. Enough of the history lesson, if you haven't installed an external cooler, do it. Put the thing in a place that can get great air flow no matter what type of cooler you run; Heat sink style, Plate and Fin style or the traditional Tube and Fin style. In fact a cooler with its own fan is the optimum route to go, these can be mounted anyplace too, since they don't need vehicle movement to provide air flow. I run an 12" Derale Heat Sink Cooler, it's good, but not great, I am going to do a better one with a fan. Here in the pictures, the first set up with my steering cooler on top of the crossmember, this got good air flow due to it being in the path of the factory radiators airflow being sucked over it. Then in the next picture, because I got a new larger trans cooler, I had to relocate the steering cooler below the crossmember and I definitely noticed an immediate lack of cooling on hot days on really slow trails and crawling scenarios (It only gets airflow when moving forward at a good pace) I now have to start adding more throttle to get the steering to turn when at a stop, where as before when the fluid was colder, I could use one finger to turn the wheel with no throttle input. The latest PSC pump seems to be doing pretty good for me, sorry to hear about yours Dave that sounds like a defect, but I will know more about my newest one in a few more weeks (or a month) when the southwest heats up. I was on the trail yesterday and it's really the hottest conditions (85-90 degrees) I have run since the install of the newest pump last september. It seemed to not fade like the old one did in the heat. Not sure if any of this helped you guys, but it's simple physics- a pump that gets hot from running in an engine bay, the job it does making pressurized fluid to push the ram assist rod means its going to make heat, no airflow over the parts because of what we do on the trail means heat staying in the engine......parts are going to fail.

Mel Wade and I have been discussing ways to defeat this every time we wheel. Here is my ultimate solution= much, much larger fluid reservoir maybe double the capacity we are currently running and a larger plate and fin style cooler with electric fans.

Greg thanks for shedding some light on this. I did put a cooler on but I almost used the factory reservoir which I'm glad I didn't after what you said.

Jeff, no problem! Unfortunately if you burn a pump, it's not as simple as just going down to the parts store and buying a new replacement. However in reality, you actually could find a few different model off-the-shelf pumps that would work because of dimensions, but you need to drill and tap the ports on the pump to fit the -8 size fittings (I think, it's been awhile since I messed with the thing and there are -6,-8,-10 sizes). Also, there are springs that are rated for the higher flow within the PSC pump that an off-the-shelf pump does not have.

As for the cooler, the higher volume fluid capacity it can hold and the more air you can flow over it are obviously going to be the key to saving those pump internals. Hope you have zero troubles, but just realize these thing can be finicky. Don't let it kick you in balls and frustrate you. If you have ever seen the "Florence Junction Highlights" video that Eddie and Cindy shot last spring on our run down here in AZ, both Mel's EVO1 and my EVOJEEP had burned up steering pumps the entire time. So you can still drive should your pump burn up, it's just the really low rpm stuff that makes it feel like you are turning two flat tires unless you are in the throttle (2000+ rpm)

Greg, can you tell me exactly what I'll need then? My front 60 will be here in a month and ill be installing the PSC assist steering too. You can PM if you'd like. Thanks

Here is the set up that Off Road Evolution typically installs on the rigs like mine and Wayalife's that run aftermarket axles like the ProRock 60's

And this next link will give all the options that PSC sells. One of these kits should do it for you. Obviously you can piece all this together by getting the parts individually, but PSC can match all the stuff so there is no guessing about what, which, or how many of an item to get.

Hope this helps with your install

This is the cooler I used. Hopefully it will do the trick sense It doesn't get as hot back here in the east. But as you can see it might rust out though, from all the salt.

That looks nice! You should do really well since its getting a lot of draw through when at low speeds the radiator fan is pulling through :thumb:
