I Love My E & P Jacks

[John and Jo]

Another question ...what do the little arrows by the green centre dot/light signify? Sometimes there's one, sometimes two when the jacks are down and the green light in the middle is green (i take that as level if its green).

Cheers

 

[Southdowners]

Don’t They indicate which of the levellers is deploying?

 

[Speve]

That tells you what side needs lifting until the dot in the center if fully green

Yes what I kinda thought but the light is green and one little arrow is lit.

Is the automatic level set point set correctly, ie when you level it on "auto" does it go to level as checked with a spirit level? and yes the orange arrow tells you which button to press to get to level but only when using manual setting mode I guess.

I accept that two jacks are always deployed together, to avoid twisting the chassis. But does anyone know how that is achieved?

If raising one side of the vehicle, say, the rear ram could be supporting about twice as much weight as the front one. So what process ensures that each ram is extended by the same amount/at the same rate?

 

[John and Jo]

Me again ...I do get some movement (slight rocking) when the jacks are well extended and the wheels are off the ground. Front or back. Is this normal?

Quite some time since my jacks were fitted but I've now noticed corrosion.
My front pair seem fine and appear to be stainless steel inner and outer rams.
The rear pair are different in that the inner rams appear to be chromed steel rather than stainless and the chrome is blistering and flaking which will eventually damage the seals.
I've emailed SAP yesterday for advice but no reply as yet.

I have HPC Hydraulics and they seem to deploy differently from my previous E and P jacks on previous vehicle. I think E and P deploy front and then back (or the other easy around). The HPC Jacks deploy one side and then the other and it depends on what it needs to correct.

Let's say standing in the van looking at the front and it is clear that the left side needs to be raised up. In this case, the right hand jacks deploy first just as far as touching the ground - then the left hand side jacks - this means that the left side jacks are not bearing the full weight and the right side jacks go back in slightly as required.

Only after that, with all four jacks deployed does it then switch to level front to back.

Have you been spraying them with lube frequently?
A good squirt of silicone spray every couple of weeks is advised.

Thats not the point I'm making really. They are not the same specification. The front are fine the rears corroded because they are not Stainless but chrome.

 

[John and Jo]

mine are E&P and have corrosion. Be intereseted to see what SAP say. Cant see they would have different spec'd jacks. Oddly though I think my rears are the ones suffereing corrosion. I'll have a look in the morning.

 

[Techno]

The fronts and rears are different units having different brackets. Maybe a different production run

 

[jezport]

Mine also have pitting near the ends.

All or just rear?

Just fitted HPC levelling. GT 85 at the ready.

 

[two]

The rear ramps will need to lift more, so could be a different spec for that reason.

 

[jezport]

All or just rear?

Both have a band at the end of the rams but rears have pitting further up the ram

 

[David and Sally]

Interesting thread. I reckon manually extending all jacks to max and spraying with GT85, or even better ACF50, every now and then would be a good idea?

 

[Techno]

The very end of the ram is just painted steel so expect rust. The ram itself is the concern. My fronts are like brand new whilst the rears are clearly not stainless steel.
I would add that the silicon spray is for the benefit of the seals, inert so it won't attack them but lubricate. The supposed stainless steel does not need anti corrosion assistance.

My rears are corroded slightly, will drop them all tomorrow and report back.

I'll photograph mine tomorrow

Interesting long term test on corrosion inhibitors, chuck your ACF-50 and GT-85 in the bin. I have been a long term user of ACF-50.

Had mine for about 2yrs now and putting the rams down is the first thing I do. The missus was very anti due to the cost however now she absolutely loves them. Use them when the moho is in storage to take some of the weight off the tyres. In my mind best investment yet. Now to convince her that we need the air suspension, probably have to wait for the lottery result.

 

[MajesticBee]

Just had E& P system installed by Rosmia in West Sussex. Mat was brilliant. On site they are brilliant and van is so much more stable especially when we have grandkids with us as they are not the lightest on their feet lol. The only downside is my drive is too steep to use them? Would not be without them now.

Try these www.AS-AirSuspension.co.uk I had them fit self leveling hydraulic system at the same time as semi air suspension never looked back and dont get sea sick any more lol, had the wind down alko steadys before but wear not that good, the front still rocked on the suspension.

This is a front leg and both rams have machining marks so definitely turned from solid stainless. No corrosion at over 4 yrs old

This is a rear leg and the primary ram is machined stainless with no corrosion but the inner or secondary ram is chromed steel and corroding.

 

[Puddleduck]

On my wish list ........

That is worrying as those pits will tear the seals in no time. Feel the need to go check our HPC legs.

 

[John and Jo]

One of my rears. They are all pretty much the same.
