Hub Nut Box Spanner

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 It can be withdrawn by screwing in a couple of screws in the tapped holes and easing it out.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
