Welding on a rear axle hub

muddstopper · Feb 27, 2015

A 60th #60 sprocket is a little more than 14.75 in dia. My axle hub is right at 13 in dia. . http://www.embmfg.com/File.aspx?id=2fcf52b7-77fe-416b-bcdc-7d9ec50ca357&display=full uses a double 68 tooth, #60 sprocket which is around 17in dia. When this weather breaks and I get back in my shop, I have to do some measureing, but it looks like a 60tooth is probably the smallest sprocket I will be able to use. My plans are to mount the sprocket to the back side of the hub, but I might end up mounting it to the end of a axle shaft down at the bottom. Dont really want to mount to a axle shaft as it would require more fabricating, more bearings, and I dont know what else. Right now my rearend housing is covered in snow. I might try to pull the hub and get it in the shop where I can actually set and stare at it and come up with a plan.

I'm sure you know you will need to leave the axle on it with bearings at the differential end to hold the axle straight.

Dont think I am following you Brad. Right now, I only plan on using the hub and spindle and also plan on cutting the center section off the axle tube. The axle tube is sq and I plan on just making a base with gussetts to hold the tube upright.

Unless it's a 'full floating' axle.

It is a full floating axle..

In that case I stand corrected.

If anybody has a small knuckle boom loader, I need to know the maxmium angle, with boom fully extended, that the boom will go down to. I figure on a maximum of 75* upright. I am trying to figure the mounting points of the cyl to the boom and the base. I am thinking about 25* below level and 75* up for a total of 100* lift.

Ebay score on a #60 double row 72tooth sprocket for the swivel, https://www.nriparts.com/power-tran...ough-bore-chain-double-row-1-716-in-sprocket/. $118.00. It was on Ebay for $89+ shipping. New Ustsubaki is $315.00, plus shipping. So far I have $400 in this boom build and havent cut or welded a single piece of metal.
