bleeding 355f1 system

I was thinking about that the other day. Other than turn the pump on while a mechanic opens the bleed fitting what could it possibly to do facilitate bleeding, and we can get the pump to operate in bursts by turning the key or build a simile cable to power it directly.

 

Oh and since you just replaced the pump, I recalled Watson posted this; When I replaced my F1 pump with a 360 one, the leads on the new pump were reversed and the pump ran backwards.

 

I simply hooked everything up and turned the system on. I filled the tank a bit and then cycled the gears a bit and drove off. It ran fine.

To properly bleed the system you need an SD2 computer. I had mine done with the SD system later but truthfully could not tell the difference.

 

The factory recommended procedure includes the SDx machine that cycles through the solenoids and purges the fluid out of all circuits. In reading the "other" board, there is a guy that invented a diagnostic switch that turns the pump on. He uses that to purge the system while manually cycle through the gears. He sells it on ebay for $250.

If you are lucky and did not let much air in the system, then it will likely drive just fine. If not, you can do what the "guy" did, or take it to the dealer and simply say "bleed it for me."

I think this is going to be a hit and miss thing for a DIY.

 

Canada is a big place - where are you located?

 

Good info, we really need to get the mystery out of the SDx as a magic wand in some regards. There are only so many things it can do given the hardware, it can operate the pump and the solenoids because that is all there is. So manually powering up the pump and cycling gears would do the same thing, that can be done with a harness and a switch. Some seem to tie the dependance on the SDx to exclusivity, I would rather maintain the car.

 

You dont want one anyway. I told the inventor all that his device did was to bypass several safeties in the system exposing it to damage. If you want hydraulic pressure, leave the key on. It will maintain F1 hydraulic pressure until the battery goes dead.

His inability to understand that just highlighted his total lack of understanding of how the system worked. Also I seriously doubt he carried liability insurance to cover your damaged hyper expensive F1 components when his stupid device destroyed one of them.


Simply creating hydraulic pressure does not give one the ability to bleed the system.
The shop manual has a very good explanation of how the system works and how to bleed it.

While a jury rigged device and the proper methodology could bleed the system you will still need to understand how to do it without damaging something expensive and that information is all there in the book.

 

Not true.



Maybe buy a shop manual and understand it so you can spread truth rather than wives tales.

 

Brian, are you referring to the workshop manual or some other shop manual?

I'm interested in learning about the system so please point me in the correct direction.

 

Thanks goes to Eddie for this bit of info.

I was having trouble getting the clutch in my 348 to bleed, and ended up having to dead head the clutch master cylinder. You can see what I did here http://www.ferrarichat.com/forum/technical-q/372483-348-throwout-bearing-removal-3.html But since the F1 has no clutch peddal I don't know how you would dead head it????? I also have no idea if the F1 has a bleed nipple on the master under the trunk carpet, but you may want to see if you can bleed it there first, and then follow Eddie's instructions for bleeding the F1 pump.

Hope that helps.

 

Man your needlessly abrasive.

If the SDx commands various components in sequence and uses various sensors, it stands to reason a general purpose computer like a raspberry pie could be interfaced via a harness to manually turn on the pump, cycle the valves etc. performing the function of the SDx.

 

that was you ???

 

You are reading too much into what I wrote. He shifts it in gear, then turns the car off, thereby turning off all the solenoids. Then he pressurizes the system manually from a separate battery to feed the fluid into a circuit that is now comprised of all solenoids turned off. That is probably not the best idea.

 

Brian is it in the shop manual because I read it twice and although a bit technical I thought basically it says to use an sd computer. My understanding was to set the octopus manually was just so you could get to a shop so they could do it properly? One question I have is can you bleed the clutch without the computer because I believe in the manual you need the sd to do that as well? Now I'm going to reread it again so I do not sound to stupid.

 

I am re reading now but I do know it says something about manual calibration give me an hour maybe it will make sense this time! No promises though.

 

The Subaru Brat AH seems to know everything.


I am sure he can guide you through it.

 

Just read the self calibration for F1 but can not find anything to bleed system still reading though in section d1 page 41 etc. I thought someone said you turn the screw with slot in it but I would not recommend without a reputable ferrari mech says its ok. These manuals give lots of info but I would not trust this without someone with a lot more experience that me giving directions.
