1967 PS control valve
« on: March 28, 2024, 08:15:40 AM »
Purchased a Bendix PS control valve from seller on eBay with 5/16" pressure port, with a date code on cap 2K 25 A. Is this valve off a 1972 model year car? Also keep seeing a 6-19-67 date Ford made a change from 1/4" to 5/16" pressure hose on all Mustang cars. Is this correct and the Ford code for this change.  Thanks

Yes Ford did change from 1/4 to 5/16 control valves in 67. As for 6-19-67date, I do not think there was a hard date for the changeover in the three plants.

The date code is stamped on the cap. Rebuilders mix the parts up so the date stamp becomes meaningless.

+1. I typically examine Shelby's and I have yet to identify a late production 67 Shelby built that had the larger fitting that hadn't been messed with. This leads me to the conclusion that it was not a hard date for change over but more for that was when Ford stopped getting inventory of the smaller style which allowed on hand stock to work its way through the system. Of course the same scenario goes for the accompanying lower pressure hose too.

The important thing is that the hydraulic line style changed maybe around 1974. You can't easily use the later line style on the earlier cars and vice - versa. The cap can be swapped to fix the date issue. Often the attaching screws are changed to a later style allen cap screw head too. The screws on a 1960's era control valve would be a integral washer filister head with a straight slot screw drive.

I suppose one without a date is better then one with the wrong date. The date is easy enough to stamp if it bothers you. https://www.npdlink.com/product/cap-kit-power-steering-valve-spool-centering-spring/149040?
