Joey Mack Posted August 12, 2023 Share Posted August 12, 2023 I found this on E-Bay.. It was cheap, and it is a bit hard to read because it looks like photo copies of photo copies.. However, it also looks like the real book.. I think I paid $25 for it. and I received a book, not a download.. I gues I am assuming you dont have the books you need.

It only covers the fuel system. Must’ve been a big stack of books for these, because my manuals over 100 pages ha. Yeah, I need some books for sure. Got a cheap oil pressure gauge working for now at least. I was rummaging though my Mack parts that came with the truck. I have all sorts of small, interior stuff that came with this. Anyone have any idea what some of these are for? Thought the B 422 emblem was cool.

mowerman Posted August 16, 2023 Share Posted August 16, 2023 Only drove one once Mack dealer Los Angeles took it for a test ride a 1965 twin drive… wound up passing they said they couldn’t finance it because it was too old wound up buying a 73 R model Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/23/#findComment-537059 Share on other sites More sharing options...

Joey Mack Posted August 16, 2023 Share Posted August 16, 2023 Bob, The wheel seals are readily available.. I cant remember the number, but Stemco has a good one piece rubberized seal, that is easy to install without a special driver. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/23/#findComment-537061 Share on other sites More sharing options...

Craig N Posted August 24, 2023 Author Share Posted August 24, 2023 (edited) So, I’m gonna tackle the rear inner wheel seal soon. I’m gonna pull the wheels, then, I’m gonna pull the spider, right? Then I can slide the drum off? Just making sure I have a decent plan before I go ahead. Also, how do I get grease into these front wheel bearings? This is the old grease cap, right? Do these covers unscrew? Anyone going to the truck show in Bolton, MA this weekend?

Mean Green Posted August 24, 2023 Share Posted August 24, 2023 Remove the hub cap remove the nut and outer bearing then Dayton wheel and drum will come off as one piece inner bearing and seal will be in the back side of the wheel assembly you removed . You don’t have to remove the spider that’s what holds the shoes to the spindle 2 Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/70672-pulling-injectors-on-a-673/page/23/#findComment-537614 Share on other sites More sharing options...
