Hub Nut Box Spanner

[ajmac]

I haven't got one to hand at the moment, so could anyone give me the details of the box spanner required to remove the large hub retaining nuts and the recomended way to side out the locking plate. Also why is the locking plate so complicated, modern hub nuts are normally locked in place with a tab washer, so cheap and simple!

The lockplate should have U section ring around it, this is to stop oil migrating from axle to hub. It can be withdrawn by screwing in a couple of screws in the tapped holes and easing it out. The eight sided hub box spanner, I forget the size, but mine was bought from a motor factors a few years back, do a search on Ebay, etc for Melco hub spanners.

You can also flame cut one out of a piece of 3/16 plate and weld it on a pipe
with a cross hole in the pipe for the turning bar
works great!

Is the correct part number. Wrench, rear axle bearing nut. Presently I have a spare to trade. Part number is rarely marked on these. Please contact me for details...

Cheers,
Harris

I think I have one of these too.

Thanks everyone, I'll pop over to the farm and measure one of the nuts when I get time. Richard, oil had crossed my mind, do you know if they are still available, all mine are fractured as the outer ring is cast iron and that doesn't take kindly to HE going off in close proximity

Regarding the ring, not sure if it is a Carrier specific part or whether it was also fitted to the trucks, if the latter, then someone like Mac's might have them.

Alastair,

You need an eight sided wrench that measures 3" across the flats.

And of course the slots are to fit the jack handle.

Are readily available in inches this side of the pond..... about $35 Cdn....... fits standard axle nuts on rear axle of C15a....... designed to be used with a 3/4 in. drive ....... adaptors from 3/4 to 1/2 inch are available...... proper socket makes adjusting the pressure on bearing much more accurate.

....but for CRS I cannot remember the manufacturer.

The maker of the bearing adjusting socket in the barn is OTC. I suspect that your memory of $35 in Canada is about what they want to charge, but $20-25 online in the US seems pretty standard. A link to one website follows - I know nothing about the company, they were just the first to pop up on a quick search. The OTC part number is 1907 for an 8 point 3" socket.

If anyone is interested the corresponding tool for the M135 is OTC part number 1924 3-3/8" 8 point.

So far there has been no mention that BB17033B is specified for Ford F15A and probably other Ford CMP's ( books says BB version for some applications and C01Q for other applications) I don't the significance of the 2 different applications.
So BB17033B is probably fairly common. My example is clearly marked with the part number.
