Mack B63SX

I hadn't given that much thought, but that may just work! Anyone have his address handy? I think I have it somewhere but may have lost it. Thanks!

Thanks Guys, I'm thinking that the offset bracket and type 24/24 is the route I may take. I have a donor source for the cans, but I doubt the backing plates off of a Freightliner will bolt up to a mack rearend without hassle. Any further ideas would be a great help. Arctic Mack I got lucky on my B63 all budd wheels! This helps quite a bit on the rears too. If I'm not mistaken the hubs should be interchangeble.

Thought I would drag this one back out and see if anyone had an answer! Thanks

Hey Rob, Thanks for the reply. My backing plates are cast steel. I believe the rears are 38,000 but not sure. How does one determine that on these old rears? I'm pretty new to this game in case you cant tell! Thanks for the help.

Hey guys, I was wondering if you could shed some light on Maxi brake conversion on a B63 with s-cam roto-chambers. There seems to be a need for an offset bracket of some sort. Correct me if I'm wrong but an offset slack adjuster may be in order to do this too. Any help on this brake modernize job will be greatly appreciated! Thank you.

Well I made it back! You guys know as well as I do how hard it is to get anything done at Christmas time. Anyway, the main transmission that I intend to use is Part # 284KB-584-B, Casting # 284KBK-582-B. The brownie is part # 281KB531. This main is an 18 speed, the brownie is from the 20 Speed. The 20 Speed main is Part # 284KB-584-B. The 18 speed brownie is part # 281KB53. These two units both have some bad bearings in them. So I thought I would use the others which are in good shape. Thanks

Will get some numbers and post back. Thanks guys.

Hey everyone, I'm new to the forum, so I'll give you some background. I have been in the process of restoring my grandfathers B63 SX self loader log truck for almost a year now. It had been in the family since the 60's and was on the verge of going to the scrap yard! So I bought the truck and have been in love with B models ever since! Pretty unusual for a 23 year old kid huh? Anyway I have gone thru the main and browny on the mack now and am almost ready to put the cab back on, two parts trucks later. Now for my first of many stupid question, many more to follow I'm sure. The B63 had a 20 speed quad, my B75 parts truck had an 18 speed quad. So I ended up using the main from the 18 speed and the browny from the 20 speed. What do I have now? 18 or 20. Where does the difference lie? More importantly will this work? Any help will be greatly appreciated!
