Needs to be wiped down with a wax/degreaser removing solvent before priming. I use 2 coats of UTECH epoxy primer, and follow it up an hour later with UTECH single stage paint. Here's the booth I made in February in my shop to prep/paint a cab for a truck that rolled over in November. There's a cardboard filter box attached to a ventilator fan, blowing air through poly stapled to a 2x4. I put more filters at the discharge end of poly tube, and that caught some paint. No idea how much paint made it into the atmosphere, I was busy inside the booth while the filters were working! The old cab is on the left, it caught a tree on its way into the ditch. Wow, that’s pretty much what I was going to do ….

JoeH Posted March 30 Share Posted March 30 If humidity is an issue in your shop air you can run it the air through 20 to 30 ft of metal pipe before the air hits the hose, this should allow any humidity in the compressed air to condensate before it gets to the hose. You'll want a purge valve (just a regular ball valve) on a vertical drop of pipe near the air hose coupling to be able to blow any excess moisture out as it collects. Blowing moisture with you paint is horrible, I have to use the air hose on the far side of the garage from the compressor to paint. The air goes 40ft across the ceiling through a metal pipe then drops 12 ft down from the ceiling to the air hose connections. By the time the air gets to the hose there's negligible humidity in it. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73175-mack-b873sx-restoration/page/3/#findComment-549118 Share on other sites More sharing options...

hicrop10 Posted March 30 Author Share Posted March 30 Is there any difference between the B80’s and the B60’s cabs other then the lip under the drivers seat of the B80’s.My reason for asking is the two panels that I have the sanding disc on are not original,but they do work so I will most likely leave them in.If someone out there would have a cab for a B80 series laying around I would like to get a look at it. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73175-mack-b873sx-restoration/page/3/#findComment-549150 Share on other sites More sharing options...

mowerman Posted March 31 Share Posted March 31 I think I probably might have mentioned this before. I don’t think most of us thought you were going to get so deep into this project. That’s excellent. Many pets on the back ha ha coming along nice thanks for letting us know….

Popular Post mattb73lt Posted April 3 Popular Post Share Posted April 3 Both cabs are identical and would interchange without much issue. One difference is the cowl area on the passenger side depending on the air cleaner arrangement, it may or may not have cut outs for them. Most B81 arrangements pass through the rear corner of the hood. The main difference is the depressed floor under the driver's feet. Those couple of extra inches really make the cab more comfortable for taller drivers. I saved this picture from somewhere on the internet of a repair someone made to their depressed cab floor. I thought it was a decent repair using heavier material to do it. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73175-mack-b873sx-restoration/page/3/#findComment-549339 Share on other sites More sharing options...

mattb73lt Posted May 26 Share Posted May 26 I've been having trouble posting pictures, too. If I add them when I post they fail. After I post I go back and edit and add them there. Then they appear.
