locknut w/wo washer for thermal clutch?

[Solomon7]

My Hayden thermal clutch came with 4 washers to go under the mounting nuts to the engine side. My mounting nuts already are locking nuts. Do I still need to put the ones in the box under my locknuts?Are thy just to take stress off the clutch flange when I torque them on to the engine? Stuck under the hood till I know! Thanks all! It's one thing after another with a new rig

If they will fit, I would use them.

Is the Hayden slotted so the hole is not round?

[Solomon7]

Yeah it's slotted. Thinkin' I'm gonna put the washers on and just make sure the split is on the clutch flange b4 I tighten the nuts down . Sound right?

[AlohaBra]

Yep..that is why they are supplied.
