xdudebrahx Posted September 26, 2014 Share Posted September 26, 2014 It's on an 86 R. I want to buy some of those half moon hub covers and I don't want to order the wrong ones. Any tips on where to buy those? Quote Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/ Share on other sites More sharing options...
41chevy Posted September 26, 2014 Share Posted September 26, 2014 I've always went to Speedway Motors and bought a set of Baby Moon hub caps. I set them upside down and level put a ball from a bearing and give it a rap to mark the center. Drill a 3/8 hole and Chrome Acorn nut to bolt it on to the 3/8 bolt and a stop nut that you have welded to the center of the hub. Course someone here may have an easier way to do it.

doubleclutchinweasel Posted September 26, 2014 Share Posted September 26, 2014 'Bout all I can tell you about that hub is that it appears to use a double-splined axle shaft!

Superdog Posted September 26, 2014 Share Posted September 26, 2014 If I was you I'd just paint it up nice,then get chrome nut covers for all the nuts 2 Quote Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/#findComment-261191 Share on other sites More sharing options...

I thought the baby moon hub caps would really set it off but I'm having a hard time finding anything for those style axle shafts. What are they even called?

Superdog Posted September 26, 2014 Share Posted September 26, 2014 just your normal 44k rear set up,instead of the axle shaft being welded to the hub cap,both ends were splined,so your axle was actually 2 pieces,the shaft and the cap 1 Quote Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/#findComment-261203 Share on other sites More sharing options...

I thought the baby moon hub caps would really set it off but I'm having a hard time finding anything for those style axle shafts. What are they even called?They're double-spline axles.Pretty sure they made 44K rears with both welded axle and double-splined axles.Those having 6 bolts, instead of 8, would suggest lighter than 44K...I do believe.

2stacksuperdog Posted September 26, 2014 Share Posted September 26, 2014 I would do what superdog said and just put the chrome nut covers and paint it up. I personally like the look of the cone axles. 2 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/#findComment-261205 Share on other sites More sharing options...

2stacksuperdog Posted September 26, 2014 Share Posted September 26, 2014 My R-model with 38s has 8 bolts, our RD has 44s and 6 bolts, our superliner has 46s with 6 bolts and a Dm800 i moved has 65s with 8 bolts. 2 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/#findComment-261209 Share on other sites More sharing options...

Bigdogtrucker Posted September 27, 2014 Share Posted September 27, 2014 6 bolt cone for 44's,8 bolts are heavier.38K flats are 8 also I believe. Quote Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/#findComment-261224 Share on other sites More sharing options...
doubleclutchinweasel Posted September 27, 2014 Share Posted September 27, 2014 Suppose the double-spline axle setup uses a different number of bolts than the flanged axle?My 8-bolt 44s are the flanged axle, not the double-spline version.

2stacksuperdog Posted September 27, 2014 Share Posted September 27, 2014 I looked through my pictures and seems all 44k/46k have 6. 38s all have 8. 58s and 65s have 8.

6368 Posted September 27, 2014 Share Posted September 27, 2014 I always thought it would be neat to send the cones out for chroming. bet it would be pricey though. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/37194-what-hub-is-this/#findComment-261230 Share on other sites More sharing options...
doubleclutchinweasel Posted September 27, 2014 Share Posted September 27, 2014 I can't find the document I had which gave the axle ratings for the old axle numbers. Sorry. Pretty sure I looked mine up somewhere (possibly a Euclid chart?), and it said 44s. Could be wrong, though, since I can't find the blasted thing.My springs are light. Probably 34s or 38s. So, they COULD be 38s. I just plain can't remember.They are SWDL-751s, if anybody has the numbers. Should be same rating as more common SWD-75.And, yes, these are 5-spoke wheels. That might also point to 38s... 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

That should state the rating.Looking at it right now. The problem is that Mack had more SPRING ratings than they had AXLE ratings. Like I said, the springs are light. In fact, the build sheet only shows 32K on the rears, as well as on the trailer, as that was the legal max on tandems in 1970.Somewhere I had located the actual axle ratings, which were higher than the springs. I think I may have found it by looking at bearings. It is actually the bearings which limit the load you can put on an axle, anyway.I just can't freakin' find that blasted sheet. I think I'm finished for the night! Quote "Eagles may soar, but weasels don't get sucked into jet engines."

xdudebrahx Posted September 27, 2014 Author Share Posted September 27, 2014 I guess I'll just get them painted up nice first. Probably buy a boat load of caps for the nuts. What's the best place to buy em cheapest? And does anyone know what size they are off hand? I wanna do the nuts on the cleats and the nuts that hold the spoke to the drum.
