DeereMan Posted May 31, 2023 Share Posted May 31, 2023 Trying to plan what im going to do with the AC on my 84 R686. My evaporator is bad, heater core leaks, fan is loud, plastic is cracked etc. I was leaning towards the red dot 8820 upgrade, no longer available. I do have a RB parts cab with the newer system, i think its the same as the 8820. Thought about putting that in?

Joey Mack Posted May 31, 2023 Share Posted May 31, 2023 there is a unit that mounts under the right seat, and the cooling fan and condensor mounts on the frame rail. I t uses the A/C compressor on the engine... I have seen 3 of these in service. they work good but it blows on you from under the seat, so a small dash mounted fan ( just like any R model) does help.. I'm sorry that I dont have a picture of the Data Plate for one of them. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72909-r-model-ac-options/#findComment-532245 Share on other sites More sharing options...
Brian L Blaylock Posted May 31, 2023 Share Posted May 31, 2023 Those red dot units that mount to the back of the cab work really well Quote Link to comment https://www.bigmacktrucks.com/topic/72909-r-model-ac-options/#findComment-532246 Share on other sites More sharing options...
880joe Posted May 31, 2023 Share Posted May 31, 2023 I see no reason that the unit from your RB parts cab wouldn't fit right in your cab. Also you wouldn't happen to have the hood from your RB parts truck? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72909-r-model-ac-options/#findComment-532248 Share on other sites More sharing options...

Guy that gave me the cab tried to give the hood away for five years and couldnt and threw it away about two months ago. It wasnt in great shape. Thanks for your response 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72909-r-model-ac-options/#findComment-532250 Share on other sites More sharing options...

mrsmackpaul Posted June 2, 2023 Share Posted June 2, 2023 I bought a red dot under the dash thingy for my truck a few years ago Imported from the States Princess has no idea how much I spent and it will probably stay that way until Im planted Anyway after getting this marvelous bit of gear I have to chop it apart to make for RHD instead of LHD Should of just flipped the photo on the order form So god only knows when that might happen Apparently they are good units, will let you know in the next decade or two Paul 2 Quote Link to comment https://www.bigmacktrucks.com/topic/72909-r-model-ac-options/#findComment-532325 Share on other sites More sharing options...
