I have a 1973 and I rebuilt the actuators. I still am having a problem with them not holding vacuum. Can the "yoke" adjustment cause this? Maybe it is not opening all the way? Looking for any help! Thanks in advance. I did replace the inner seal, retainer ring and out seal.
Hi s&b,
When you say you rebuilt the inner seal... are you saying you un-crimped the canister and replaced the inner diaphragm? If not, that's where you leak could be now.
Perhaps the 2 parts you replaced were the rod seal and dust boot.
Happy Thanksgivig!
Regards,
Alan
FYI Willcox has these actuators for $105 for the pair...... I just installed a set....along with new control valves for $33 each... My lights flip up quick and even now....
