Title: 84 K30 Rear Proportion Valve Photos needed
Post by: srodster on May 25, 2014, 12:55:07 pm: Anyone have some photos of their rear axle with the height leveling proportion valve? I have seen the photos from the manual, but would like some up close photos of the linkage to the valve, and the bracket from anyone that has a functional valve. I'm doing a rebuild from a while ago and think I have misplaced some parts. Also, a source for new one would be great too.

I'll attach a photo of the one I have.
Thanks.

Post by: srodster on May 25, 2014, 02:53:48 pm: Yah, can I get another one on the left side of the valve to understand where the bracket that holds the rubber line from the pumpkin attaches to? Is it the frame?
(My issue is that I have a k30 suspension with a c20 frame (cc, longbed))

And trying to make sure parts and pieces match up. Don't know why I decided to do this, but I did....., about 18 yrs ago, and now trying to make progress before my Wife leaves me...., ha.

Post by: srodster on June 05, 2014, 08:27:03 pm: That is certainly an option, but I may need a little coaching on the correct hook-up, and do I have the correct valving left, if it is removed, or do I need a different one........ I have never dealt with that side of it before.
