Has anyone tried rebuilding a vacuum actuator for the AC system?
Im taking a stab a replacing the diaphragm, which is completely destroyed.
As replacement cost for the actuator are in the $80 region and I need 3.
Ive managed to open one up (yay grinder).
I'm looking into different rubber sheets to just make a new diaphragm.
Then reseal the actuator. (thatll be fun)
Keep us posted on how this repair works out for you
I do not ever recall someone trying to repair one of these Vacuum valves --and on here a few times daily since 2006
I need two valves and will be fixing my confort control in the near future myself
The key may be getting the --correct blader material
The major issue is --you will not know how your own design might hold up --for the long haul -and you really do not want to redo this job again after just having had the entire CC system apart and then back together
Just that may justify having to go for the expense of the new valves
Redoing the CC system is very time consuming and expensive but OH what a nice thing to have working to enhance the rides pleasure
I don't think they are 80, I thought closer to 50. Did you check all three with a vacuum hand pump? I don't known if the one under the hood is rebuildable. Its plastic face gets destroyed by the under good heat and oils.
Ive removed all three. The diaphragm is essential GONE. Just remnants left behind. I have a commercial version, there are actually three of these things under the hood. They are aluminum. No plastic that i know of.
I do know i have seen many 20/80 Vacuum valves with a white plastic fronts mostly on the passenger side heater box under the hood
I am sure that is what Clovis was talking about
Ahh commercial car. Its always good to post what kind of car you have and also model and year.
