skip Posted December 9, 2013 Share Posted December 9, 2013 Gday everyone. Ive got a 1970 model F785RS. It has an unusual gear stick lingage on it, but it looks genuine. It has a 9 spd roadranger in it now, but it did have a twin stick 6 spd in it from new. The stick/s stay with the cab when the cab is tilted. They are mounted into a ball socket arrangement in the floor, with the bottom part of the lever exposed to fit into a selector cup/slide which is bolted high up on the angled side of the cab gantry.All the other Australian F models Ive seen have a low mounted remote selector box mounted on the cab gantry. I will try and get a photo posted of it soon. Has anyone seen a linkage similar to this?Regards, Skip.

jakebrake86 Posted December 9, 2013 Share Posted December 9, 2013 That's a good question. Any F I've seen or owned here in the States had the shift tower mounted with the chassis, and the shifter(s) stayed with the shift tower.

Superdog Posted December 10, 2013 Share Posted December 10, 2013 that sounds like a Cruiseliner set up,protoype maybe? Quote Link to comment https://www.bigmacktrucks.com/topic/33806-f-model-gear-linkage/#findComment-220655 Share on other sites More sharing options...
39 Baby Mack Posted December 10, 2013 Share Posted December 10, 2013 That's what it sounds like to me too Mike.Ron Quote Link to comment https://www.bigmacktrucks.com/topic/33806-f-model-gear-linkage/#findComment-220657 Share on other sites More sharing options...
skip Posted December 12, 2013 Author Share Posted December 12, 2013 Thanks for the replies fellas. I had a mate tell me that it couldve been a cruiseliner setup, but I didnt think cruiseliners ever had a twin stick arrangement. Also this is on a 1970 model truck, and we didnt see cruiseliners out here until 1980. I will get a photo. I also have a quad box that I bought from a wrecker with the F model levers and it has a similar setup. I will try and get them posted soon. Thanks again everyone.

Joe Ditchkus Posted December 13, 2013 Share Posted December 13, 2013 Same subject my question. Is the shift tower and linkage on a F-Model the same for a Duplex, Tri-plex and Quadbox ? The one in question is mounted to frame with sticks mounted that do not tilt with cab.Skips's post had me wondering.The one I have is a pretty good sized unit. Thanks Joe D.

Superdog Posted December 13, 2013 Share Posted December 13, 2013 I've never been around a F model with a Duplex to know for sure,but they are they same for the Triplex,Quad and also the 2 stick 6 speed Quote Link to comment https://www.bigmacktrucks.com/topic/33806-f-model-gear-linkage/#findComment-221149 Share on other sites More sharing options...
39 Baby Mack Posted December 13, 2013 Share Posted December 13, 2013 We had early F models (steel dashes) with both duplexes and triplexes and as far as I can remember they were the same.Ron Quote Link to comment https://www.bigmacktrucks.com/topic/33806-f-model-gear-linkage/#findComment-221156 Share on other sites More sharing options...
Joe Ditchkus Posted December 13, 2013 Share Posted December 13, 2013 Thanks for replies. They were well built. I would imagine with all the compound shifts Mack did not want maintaince problems. Another question as the F-Model Mack and Brockway 400 cab were about the same would the shift tower work on a 400 series Brockway with split or married boxes. There were quite a few 400 Brockways with 4X4 trans but all I ever saw were the air shift ones. Thanks Joe D.
