Bliue dm Posted March 25, 2022 Share Posted March 25, 2022 I have an 18spd maxitorque. I want to change shifter head but splitter goes up and down. Not side to side. Does anyone know where I can get aftermarket shifter or can I switch to an eaton style shifter knob?

But, I would assume you could change over to an Eaton knob. As long as the air pressure goes where you want it to go, I don't think it matters what the knob looks like. I mean, you just have a range shift and a splitter, right? Shucks, you might could even go old school and separate them into 2 selectors; one on the knob for the splitter and one on the shifter shank for the range!

880joe Posted March 25, 2022 Share Posted March 25, 2022 I believe the Eaton shift knob uses smaller air lines Quote Link to comment https://www.bigmacktrucks.com/topic/69434-aftermarket-shift-knob/#findComment-493346 Share on other sites More sharing options...
Joey Mack Posted March 25, 2022 Share Posted March 25, 2022 so you dont have a Mack shift knob with the range switch in front and a gray colored splitter on the left side, that is horizontal? what year are we talking about here?

Dirtymilkman Posted March 26, 2022 Share Posted March 26, 2022 I also thought about using an Eaton style because you can buy them for about $35. But I chickened out. I found a PAI one for about a third the price of a Mack one. They are a little expensive now. You want a PAI 3767. https://www.google.com/amp/s/www.finditparts.com/products/7895653/pai-lsv-3767.amp Quote Link to comment https://www.bigmacktrucks.com/topic/69434-aftermarket-shift-knob/#findComment-493402 Share on other sites More sharing options...
Hans Remmers Posted March 28, 2022 Share Posted March 28, 2022 I'm not sure about the Maxitorque. An Eaton valve supplies air back to the trans for low range and the over-gear.

A friend of mine did two old school splitter valves on 8spd.

I do. I want to change shifter but I see no aftermarket support for it. All the designer shift knobs are for eatons 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69434-aftermarket-shift-knob/#findComment-494050 Share on other sites More sharing options...
Hans Remmers Posted April 1, 2022 Share Posted April 1, 2022 Just compare the operation of your splitter to that of the Eaton 3 line I described. 1 supply red. 2 low range delivery black. 3 overgear delivery (unsure- green or blue). That company twisted shifters sells an eaton valve and top combo. The valves are 1/16" pipe thread. You could change the fittings to 1/8 or 3/16 tube if necessary. Current standard seems to be 5/32" Quote Link to comment https://www.bigmacktrucks.com/topic/69434-aftermarket-shift-knob/#findComment-494057 Share on other sites More sharing options...
Hans Remmers Posted April 1, 2022 Share Posted April 1, 2022 The other issue you might run into is the top of your Mack lever might not be 1/2-13 thread.
