I picked up a 14 bolt rear axlefrom Big Rob's boss yesterday. Its an 80s Chassis cab dually, with a wms-wms of 63"-64", and has the mosterouse dually drum brakes.
I want to get it swapped in this week, but have a few questions.
I read that the carrier break for the 14 was at 4.10 and lower. I havent opened it up yet, but Im assuming its 4.10 gears, I need to got to 4.56 gears. Will I need a new carrier, even though Im installing a Detroit? I have heard that the reason the Detroits for the 14 are so cheap is because it is not a typical full carrier type for this monster.
Also has anyone got detailed dimensions for the disk brake caliper mounting plates, to convert to disks.
Thanks for the help

And Big Rob, thanks for everything. I owe you a few <IMG SRC="smilies/beer.gif" border="0"> <IMG SRC="smilies/beer.gif" border="0"> , you came through big time.

Its been a few years. But I picked up the 4.56's, Detroit, all the bearings and the yoke for 250.00 from Boyce. You might call them to see if they offer this still. <IMG SRC="smilies/usa.gif" border="0">

No way i could get lucky enough to actually have matching gears. I opened it up today and started stripping off the unnecessary bracketry. Its in great shape, but I counted 41 ring gears and 10 pinion gears so that adds up to 4.10 to me.
The dually drums are massive but they came right off, it looks like the brakes were recently serviced, before they retired it.
The dually drums put the backing plate to far away to use for the disc conversion, so I assume I just need to fabricate a new backing plate, and a caliper mounting plate to bolt to it.
I sure do like the simplicity of the full floater axle assembly, you couldnt ask for an easier assembly to remove an axle shaft. I had both side axle bearring and brake assemblies, disassembled in a bout 20 minutes.
