Dan Yager Posted July 16, 2021 Report Posted July 16, 2021 Having zero luck finding vacuum actuator for 2 speed rear end. Has anyone ever done a manual shifter? I might just be nuts, but thinking about options. Thanks Dan Quote
Dan Yager Posted July 16, 2021 Author Report Posted July 16, 2021 Topic should have beef rear end and not brakes. Sorry for any confusion Quote
Brent B3B Posted July 16, 2021 Report Posted July 16, 2021 Hi Dan, sounds like you have a two speed rear axle and your looking for the rear axle vacuum control valve? (Photo from B3GA) my B3HH has what I would guess you could call a “manual”. It acts like a high/low under the choke knob, rather than the button on the shifter. it does not use the same vacuum control valve, but rather a later model or a “farmer fix” little cumbersome but, I don’t think you “nuts” (just yet ?) 1 Quote
Dan Yager Posted July 17, 2021 Author Report Posted July 17, 2021 BrentB3B. Looks like we have the same actuator on the fire wall. My problem is at the rear end. I was thinking of running some mechanism from the cab straight to the rear end Quote
Dodgeb4ya Posted July 17, 2021 Report Posted July 17, 2021 The early "W" series trucks used mechanicalinkage to shift the rear axle...using a two foot tall shift lever in the cab....long rods going back the the 2 speed shifter lever. 1 Quote

I have that same one attached but it’s all rusted and hammered. Have had no luck in finding a replacement. That’s why I was thinking mechanical shifter. Sorry for any confusion. I’m still really new to all of this old dodge stuff! Quote

I’m still really new to all of this old dodge stuff! did you try it anyway? mine looked pretty grim when i bought it, and it wouldn't shift (it was frozen in low). a bit of time spent cleaning off the old grease, and spraying the pivots/linkages with PB'laster and i had it working. that was back in 2007. it still works today. 1 Quote

I will give that a go. Never even considered trying to see if it’s free!!! Ha! Thank you Quote
wallytoo Posted July 19, 2021 Report Posted July 19, 2021 it's the cheapest option out there; a little elbow grease and some real grease, and a little luck and you might not have to do anything else.. 1 Quote

I didn't pay attention to your picture. I have a couple shifter diaphram's that look the same. They shift just fine. Lube the pivots up as previously mentioned. You really need the factory shop manual to fully understand how the 2 speed shifter system operates too. Quote

I have the manual and have been reading about it. Do you know what the vacuum do dad does behind the speedometer? Quote

Do you know what the vacuum do dad does behind the speedometer? That little gearbox at the back of the speedometer senses when the rear axle shifts into High or Low range and adjusts the speedometer reading so it reads correctly in both gear ratios. 1 Quote
