New to the Forum, new owner of a box cat, starting to clean,paint and assemble without a manual yet, sadly!
Wondered if anyone knew how much torque to apply to the drive sprocket nut.

Be happy for a ballpark number to start with.
Thanks

No idea. There are torque specs for specific sizes and thread pitches. With that info, you can get close. The link is to a manual I found. Jim

I have a few HD-5 parts left from one my father in law had.

The torque should be 1500lbs for the sprocket nut

DadsdozerHD5 here agrees with Hector 1500 ft lbs

Thanks for the number. I've found what may be a repair Manual on ebay. But for now I'll just hang my 150# carcass on the end of a 10 ft pipe over the handle of my wrench. I removed the old nearly toothless sprocket and I don't remember the nut being all that tight. Both splines were like new? ?
