gafarm49 Posted December 23, 2022 Share Posted December 23, 2022 its collapsed and the fuel gauge doesn't work. I have a dual tank setup off my 1086 that got the yar cab. How hard would it be to get the Guage working if I swap them. Now is the time if I'm gonna Quote Link to comment Share on other sites More sharing options...
Dan Robinson Posted December 23, 2022 Share Posted December 23, 2022 Should just have to plug in both senders. There should be a jumper wire plugged into the lower wire harness. Unplug that, plug in lower sender. Your 3pt arms may interfere with a 1086 tank. But I cannot conform that. 1 Quote Link to comment Share on other sites More sharing options...

We punched a hole in our 986 before because of the 3 pt arm. Quote Link to comment Share on other sites More sharing options...

gafarm49 Posted December 27, 2022 Author Share Posted December 27, 2022 Thanks for the heads up. I will swap the arms. I would have busted the tank for sure Quote Link to comment Share on other sites More sharing options...
acem Posted December 27, 2022 Share Posted December 27, 2022 You loose your tank drain when changing to the 1086 tank. Quote Link to comment Share on other sites More sharing options...
Matt Kirsch Posted December 27, 2022 Share Posted December 27, 2022 I can see where that would get messy. My question is, WHY? Just use the same tank and 3pt arms on all the tractors, save on inventory. Might've meant the difference between Tenneco in '85 and an Independent IH in 2022... 1 Quote Link to comment Share on other sites More sharing options...
Jeff-C-IL Posted December 27, 2022 Share Posted December 27, 2022 THe 986 arms and tank probably were like - $0.50 cheaper than the 1086. Which when you are building 10000 of something is a significant factor. The molding & casting companies were likely forced to eat the cost of the different molds if they wanted to keep the business. And thus IH could say that the 1086 had a heavier 3pt and a larger fuel tank then the 986 Quote Link to comment Share on other sites More sharing options...
12_Guy Posted December 27, 2022 Share Posted December 27, 2022 Don’t think I ever realized the difference in tanks or hitch arms. Thanks for the info. Always good stuff on here. Quote Link to comment Share on other sites More sharing options...

However if you consider the cost of inventoring 4 parts instead of two I doubt it would pencil out. Don't the 3088-3688 use the same arms and tank as the 786-986? I'm pretty sure IH did most of their own casting back then. Quote Link to comment Share on other sites More sharing options...

Diesel Doctor Posted December 29, 2022 Share Posted December 29, 2022 GM quit putting radiator petcocks in their pickups in 1973. It saved them $0.25 per vehicle. That adds up when you are cranking out tens of thousands of vehicles over time. But they got so much grief from the mechanics and owners, they put them back in again. They used to listen to the customers/mechanics in that period of time. 1 Quote Link to comment Share on other sites More sharing options...
