Convertible Hydrolic Drive Pump Replacement

[Jeffrey Nablo]

I have a 99 996 Cab(top not working)and the dealer has diagnosed my problem as a failed Hydrolic Drive Pump. I would consider doing this myself but would love to hear from someone with experience on this one. The estimate was $980 for the pump....add bracket, washers, fluid and 3 hours labor for a total of $1571.

Thanks for any input,

Jeff

i had mine replaced at the dealership for about that amount. When i checked into it there were some calibration procedures that have to be done with the porsche diagnostic computer, so it wasnt just a "replacement" thing from what i learned. If course there was also the variable sensor that i had to replace on mine

I would check our sunset porsche ( i think that is the sponsor) because i think when i looked it up after the fact they were like 300 bucks cheaper on the parts

if i were to personally do it over with i would replace the parts and then take it to them to calibrate it, to save money on parts and cut down on their labor.....

I have replaced the cylinders and fluid. I did'nt have to calibrate anything. Perhaps he meant bleeding air out of system.

Thanks for the replies, I'm waiting on a price from sunset and have a local shop with a PST-2 for calibration. Did you need to bleed the system when you changed cylinders and fluid and if so how did you do that?

there were other issues i was having, if you just replace the motor you may not need to calibrate it

once you open it up it is pretty easy to figure out, just unbolt the lines and pump and bolt the new one it, the filler bolt for the hydrolic oil on some are on the back, mine was on the bottom, i just filled the unit up with oil cycled it and made sure the level was full after cycling it
