water impeller nut

Or high temp RTV. Please dont strip it out!

I use the knuckle of a Socket and wrench decent hand tight with a small amount of blue Loctite.

Make sure the impeller is correctly seated on the shaft splines and snug it by hand with a socket. As the impeller rotates the prevalent stress of rotation keeps it tight.



As others have warned above, do not over-tighten.

Your question took my breath away. As others have said, do not overtighten. You could break off the end of the camshaft and then you'll be in a world of hurt. If that happens, you have to get a new motor. I've successfully used high temp silicone sealer on the copper washer. Some of us on this forum anneal the copper washer and some of us get new ones. Auto parts stores usually have them.

Snap. Yep that was to tight.



The second question is how much work does it take to fix a snapped off set of threads. It has been done and you don't want to know.



Also Harbor freight has basic 1/4 drive torque wrenches. Some may argue that they aren't calibrated right but 0-10 pounds is just fine.

I think those smaller ones are fine Don.It's the larger 1/2" + ones that get vague at the low settings and those Bar type ones are just not up to it and also so cumbersome in small places.

Oh i'm not going to disagree Shep. I like both of my harbor freight torque wrenches. Obviously I really only need the 1/4 drive on these engines but some have went out of their way to tell me ....................... and that anyone using them can ......................

On a budget they work fine.

I just torqued some head bolts on a Jeep with the 1/2 inch Harbor freight torque wrench. Then I went to use it on the valve cover gasket. 140 pounds to 8. Watched my buddy snap the bolt off. So I grabbed the wrench and did the same. Totally not accurate less than ? pounds.

It takes a"feel" for the bolt being tightened, and a little common sense. When you are tightening the bolt, nut, whatever and it starts "feeling" DIFFERENT?....Thats either the threads stripping, or the bolt shearing. ALL'S that is NEEDED, is when you feel the fastener seat?.........I would think, an 1/8 to 1/4 turn would be sufficient , in most cases.

IMHO.......ESPECIALLY, on those smaller threads. If you're worried about the vibration backing them off?........A little lock-tite does good. If you think that you can tighten these smaller threads ONE TIME and NEVER have to check 'em again?....In more cases than not, you're going to twist off or strip it!!



Hope this helps.

A "FEEL" is a firm CONSTANT pressure........NOT A JERK!!!!!.......SSSSSNAP!!!!!!!!!!!!.....



That is for TIGHTENING........For Loosening?.....On THESE old bikes? (and I KNOW what you're thinking.......lol), tighten those Mothers with the SAME torque you LOOSENED 'em with?.......SSSSSSSSSSSNAP!!!!!!!!!...........AGAIN!!!!!!



This is getting me "thirsty".........rofl

Does Snap-On have a sister company. Maybe two. Hand-tight and Snapped-Off
