Why use a recirculating system on a slave cylinder?Hello everyone
Im having a very hard time bleeding slave cylinder. Anyone familiar with Porsche and have any ideas? Im stumped lol. Its a recirculating system, on slave top is supply bottom teturn and both go back to recirculator.View attachment 130410View attachment 130411
Because i have no other way to hook up return lineWhy use a recirculating system on a slave cylinder?
Agreed but since transaxle is flipped lines are flipped aswell.Logic says bottom should be supply and top return so that the air will bleed out
Yes it is flipped. Ive bled from both slave and recirc. Im not getting anymore bubbles but still not engaging. When i go to put car in gear it rolls but wont actually lock in.Is this transaxle flipped upside down? If so, you may need to fab a device to hold the piston from blowing out the end so you can hold the slave up side down (from current position, right side up like OEM install) so when you bleed the bubbles can escape.
If the slave is in OEM orientation, you may just have to make a mess and crack open the return at the recirc valve.
Where are you trying to bleed from now?
OK, now I see what Porsche did. I was not aware that Porsche had changed from a simple slave cylinder with a single line from its M/C to a complicated system that added a separate return line simply to eliminate a bleeder fitting. Sometimes Porsche does weird thingsBecause i have no other way to hook up return line
Thank you, appreciate pics.Looks like you have the 997.1, that only has a supply with bleeder.Joe I also have a Porsche 997 transaxle with a Wilwood clutch setup. I created a fitting into the original trans hydraulic port and connected the hydraulic hose. I bled from the fitting (black cap) next to the hose on the transaxle. I never had an issue and works great. Hope this helps
