843 wheel lug nuts - torque

[donald73d]

I looked in the service manual and could not find the torque for the wheel lugs nuts and if I need to tighten in any specific order. Or can I just tighten in a circle with my cordless impact and call it a day. I know with cars you need to worry about warping the rotor. But probably not with the Bobcat.

105-115 ft lbs. on page 8-4 of the service manual. Lugs on everything should be tightened in a pattern.

Agree with OldMachinist, the reason for cross torquing bolts (done in stages is better too!) is to establish linear compression of the structure ie., the hub / rotor / flywheel or whatever. Cross torquing will also ensure longer wear life of the part(s) involved. Torquing bolts (or engineered stretch) is probably one of the most overlooked items when it comes to proper maintenance of machinery today! my 2c.. JLM

I agree with the cross torquing. So why isn't it 1-2-8-7.....?

8 lug pattern starts out the same as a 4 lug to get the wheel centered.

Found one for 10 lugs
