Popular Post h67st Posted September 14, 2018 Popular Post Share Posted September 14, 2018 I wanted to get the transmission and differentials blasted clean before I rebuild them so I wouldn't be doing that with new seals and such. Yesterday I had a guy come out and blast them (he used crushed glass; it did a great job and left less mess than sand) and then I put on a coat of primer. I used a Devilbiss FLG4 HVLP gun and Nason epoxy primer; I'm no body man but it was easy to use and went on really nice. It's great to see something look good after dealing with so much rust, grease, and crud. 4 Quote Link to comment https://www.bigmacktrucks.com/topic/54280-blast-and-paint/ Share on other sites More sharing options...
eddeere Posted September 14, 2018 Share Posted September 14, 2018 Great work . That is a good paint gun for the price . I have one and have used it mostly for primers and some finish work . That Nason epoxy may have a recoat window . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/54280-blast-and-paint/#findComment-406003 Share on other sites More sharing options...
Freightrain Posted September 14, 2018 Share Posted September 14, 2018 Dustless blasting, same thing I did with my rims/hubs on my truck this spring. Still some glass residue in the gravel in the driveway, but worked well. 1 Quote Larry 1959 B61 Liv'n Large......................

Yeah, I'll be way past the window, but I can scuff it and shoot another coat of primer when it's time to top coat. My goal here was to get them blasted before I rebuild them and put the primer on to slow down the rust.

eddeere Posted September 16, 2018 Share Posted September 16, 2018 Epoxy primer is the way to go . Sometimes difficult to scuff up . I sometimes follow the next day with a coat of urethane primer it is easier to sand or scuff . It looks as you are off to a good start.

My goal here was to get them blasted before I rebuild them and put the primer on to slow down the rust. If you're going to rebuild them I'd say take the carriers out and revise the bearings the interwheel diffs turn on. I got there on two pairs of 1945 Mack carriers which looked almost the same style as yours and later on a pair of CRD92/93 off 1988 R-model. Found out outer races deadly pitted on 3 pairs of the bearings (6 pieces of 8 at all) of 1945 and on two pairs (all bearings) of the R. Could buy new races and cones but spent sufficient worth on them and pre-load reinstall is a procedure to pass through. On the other hand I'm not sure to advice you to get in there or to not. I'd expect nearly 80% chances your bearings are bad but I'd also expect the same thing for the most running old Macks. And they're all running at the same time Edited September 16, 2018 by Vladislav 2 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/54280-blast-and-paint/#findComment-406101 Share on other sites More sharing options...
