    I plan on upgrading the F1 transmission motor/pump head. To do so requires that the two fittings at the pump head be separated. One is the input from the reservoir, the second is the high pressure output.

    A procedure published by Juri Gelovani showed how to purge a new pump head. However, it is unclear whether this procedure was sufficient to adequate purge any introduced air in the high pressure output line. See, http://www.ferrarichat.com/forum/360-430-sponsored-yellow-compass-group/268458-360-f1-hydraulic-pump-relay-pictures-inside-2.html

    Has anyone tried Juri's procedure when fitting a new pump head and were you successful? If not, would just using the purge valve on the top of the engine frame allow for successful evacuation of any air that might be introduced into the system with a pump head change?

    Thanks.

    Jim

    Jim- I would have the system bled with a diagnostic tool if I were you. A good time to change out your F1 fluid, too, which should be done at least every three years, but was not in the maintenance recommendations until the 599 came out.

    I recently swapped out my F1 pump in my F430 ...but just the motor not the head. Was there a reason they you changed out the head as well?

    Just changing the F1 pump head you don,t need to purge system and if you need to purge it best with a scan tool or the F1 system you would need to be running the car and bleed the F1 pump with 2 bleeders

    I believe changing the pump head does require purging. Changing the motor that the pump head is attached to does not require purging. Those 2 can be separated without the release of hydraulic fluid and letting air in the system.

    When I decided to upgrade the motor, I was impressed with the performance increase that both an upgraded motor and pump would bring to both decreased pump priming time and the ability of the combination to keep system pressure at a constant level during rapid shifting. Since the cost of the new pump was $150, I figured I would upgrade the motor and pump at the same time.

    changing the F1 motor only and not the hydraulic head does not require purging

    So....what are you saying here?
    To me your saying that purge is not needed when changing the pump. It contradicts what you said later.
    I'm Just trying to put correct information out there. You're is incorrect.....again.

    I guess you never replace a f1 pump on an 430 then without purging the system, just remove the front 4 bolts and 1 in the back on bracket if you like to know very simple , I think you don't know what talking about it very correct , and yes that what I,am saying

    scuderia- What I have concluded on you is there are three possibilities:

    1) you do not know what you are talking about (my favorite)
    2) you do not understand what anybody is saying
    3) you cannot express yourself well enough to explain what you are trying to say

    If you remove the pump and head, any pro will tell you that introduces air into the system.

    Note that I ignore nearly all of your questions and only a rank amateur would think a 550 has an F1 system. All most of us can hope to do is steer folks away from your advice.

    Hey Terry , if you read the thread right were talking about replacing a F1 pump and were not introducing any air into the system or remove any lines just the F1 pump very simple job you DON'T need to purge the F1 system, what don,t you not understanding Terry, get your story straight before you open your big trap .

    Brian- I actually bought it for my techs. The AE software can do all the bleed and self-test functions, but my techs are the ones who get their hands (gloves, actually) dirty.

    With the help of all the post on this forum, I just finished changing the fluids on my F430 and the last fluid to change is the F1 hydraulic system. Like Brian, I have the AE Software and searching for a purge/bleed procedure for the F1 transmission. WSM is lacking in this area.

    Anyone have an ideas where to find the procedure, even if it is using an SD3.

    Thanks

    Look on Aldous Voice's site. Procedure for 360 should be very close.
