ThermoDog Posted December 26, 2020 Share Posted December 26, 2020 (edited) Greetings, My first posting on this really amazing site. I’ve casually browsed here on and off. The dog runs deep in my blood. Used to bug the crap out of the guys in the shop at the dealer when I was a kid. “What’s this for” What does that do?” I’ve owned a couple B models and two or three R models over the years. I currently have a 1980 RS686; an ex-mixer. I’d love to have a B83SX and while I think my favorite are the RB series with setback axle (not sure I’ve ever seen one out West here), I’ll stick with what I’ve got and enjoy it. This leads me to a question about steer axle wheels, tires and hubs. Hoping someone can help identify the rims and spoked brake hubs on the green R model in the attached picture. My truck is the red R model. I would like to install the wheel assemblies identical to the green one on my red one. Anyone happen to have a pair (set of parts & pieces) taking up space or know where I could source them? What’s involved in swapping them? Much appreciated!

alex g Posted December 26, 2020 Share Posted December 26, 2020 Greetings Thermodog. I think I have what your looking for on a 87 DM I would sell but depending on where your located the shipping would probably be too expensive. I'm in Ontario Canada.

ThermoDog Posted December 26, 2020 Author Share Posted December 26, 2020 Wow, what a quick reply. If you could send a picture my way, I could handle the shipping. Any idea of what you’d want? Thank you, Alex! Quote Link to comment https://www.bigmacktrucks.com/topic/65380-wheelhub-identification-help/#findComment-466172 Share on other sites More sharing options...
alex g Posted December 26, 2020 Share Posted December 26, 2020 I'll try to get a pic this week. It's at the farm not my house. Do you want complete front axle or just the hubs?

ThermoDog Posted December 26, 2020 Author Share Posted December 26, 2020 I guess I would need to figure out if the parts and pieces are a direct swap onto the existing spindles of my axle. I can’t imagine why they wouldn’t be a direct fit. Maybe someone can jump in on that with an answer.

ThermoDog Posted December 26, 2020 Author Share Posted December 26, 2020 Alex, What are you doing/going to do with that truck? That looks like an RB hood on a DM cab? Setback axle(angled headlamps)? Is she a runner? Quote Link to comment https://www.bigmacktrucks.com/topic/65380-wheelhub-identification-help/#findComment-466190 Share on other sites More sharing options...

ThermoDog Posted December 26, 2020 Author Share Posted December 26, 2020 So I’m guessing the hubs are Daytons then? Quote Link to comment https://www.bigmacktrucks.com/topic/65380-wheelhub-identification-help/#findComment-466194 Share on other sites More sharing options...
ThermoDog Posted December 26, 2020 Author Share Posted December 26, 2020 You guys, back East, have all my favorite Macks! Especially New England and the Jersey area. I could swear that’s an RB only grille. Or so I was told by a dealer parts tech.

ThermoDog Posted December 27, 2020 Author Share Posted December 27, 2020 Let’s see if I have this right ~ Dayton six spoke hub attaches to the brake drum with six nuts. Rim attaches to the hub with six clamps. I need: 2 rims for 425’s 12 clamps & nuts 2 six spoke hubs 2 hub covers 2 brake drums Is that about it?

Joey Mack Posted December 27, 2020 Share Posted December 27, 2020 Hello Alex.. Have you got one of these dust shields? I am working on an '86 RW and the owner wants them put on the rears. I have 3, Go figure 🤔 Thanks, Jojo Quote Link to comment https://www.bigmacktrucks.com/topic/65380-wheelhub-identification-help/#findComment-466202 Share on other sites More sharing options...

Joey Mack Posted December 27, 2020 Share Posted December 27, 2020 Thanks Alex... Those usually get tossed out during a wheel end repair... I will try to convince my customer to leave them off...

Mark T Posted December 27, 2020 Share Posted December 27, 2020 (edited) Don't forget you're going to need the 20" if you plan on using wide base steering tires (425s) That picture has 22" and 20" in it . You'll need these guys Edited December 27, 2020 by Mark T add pictures Quote Link to comment https://www.bigmacktrucks.com/topic/65380-wheelhub-identification-help/#findComment-466214 Share on other sites More sharing options...
ThermoDog Posted December 27, 2020 Author Share Posted December 27, 2020 Thank you, Alex. Mark, any idea on how wide the rims are for 425’s?

Mark T Posted December 27, 2020 Share Posted December 27, 2020 I believe you'll want a 12.25 X 22.5 rim. But as far as what offset will end up working ?? That's a little more specific to the truck.

ThermoDog Posted December 27, 2020 Author Share Posted December 27, 2020 Okay. Thanks, Mark. Those open spokes sure look great and it would be great if I could come up with something for my R. But I suppose I’d really need the rears as well.
