hemtt wheel nuts

[baxter]

Does anybody know if there is a specific pattern to tightening the nuts holding the two halves together.

just like a rim to the hub. just cross the pattern

I posted it once and it was "poo-poo"'d as too troublesome to those involved. It is in a cross pattern in 3 successive steps as I recall, torque to 450-500 ft.lb. At least it is less than the lug nut torque.

It is in a TM. But I'm too lazy to look.

 

[Stalwart]

I did look . . . once. The torque is correct.

Thanks guys i put it together and it leaked so i thought i would ask.

Baxter, bring all the nuts down until they just touch and start to compress the o-ring. The initial part is the most critical. That is when you are going to extrude the o-ring into a non sealing surface. On the HEMTT they need the 450-500 lb.ft. to stretch the bolts so the wheel is clamped so that they can take the immense weight.

If you PM me I'll send you a link to the 25MB manual.

I just torqued mine down with probably 50-60 pounds of pressure at the end of an 8' bar and my o-rings have held up just great. Although, it might have been more than 50-60 pounds, but I'm sure they are over the specificed 450 pounds.
