Knock it off?

Can someone tell me how tight Dayton knock off spinners really have to be? Is there a recomended torque?

I have the 72 spoke set & sometimes I think maybe I'm hitting the on too tight... /bcforum/images/%%GRAEMLIN_URL%%/nonono.gif

When you get a big brass hammer that has a torque readout on it, let me know.
 
Now how long before we see a Photoshop of that?

I have the two eared nuts on mine. I purchased the big long wrench thingy that Moss sells... It's nice. I torque it down pretty tight.

Great, I think I'll purchase one of those then, Plus it's alot less wear and tear on the hub.

is it possible to wreck the threads by hitting it too hard?

Nah, you'll wreck the ears on the knockoff first.

When I got my 59 TR3A, the splines were ruined and the DPO had reefed down on the knockoffs until the friction in the tapers was enough to keep the wheels from turning on the adapters. I had a terrible time getting them off, but the threads were fine.
 
I use a 1"x1" 10" length of oak against the ear of the knock-off and hit that with a 3 lb. dead-blow hammer. All I do is snug it up real good.

It's my understanding that they will get tighter as you drive due to the flexing of the wheel. Indeed that is why they are handed differently left & right... mount them on the wrong side (or tow the car backwards) and they will loosen as you drive.
 
On my 3 I tighten the knock off as tight as possible by hand. Then while the car is still jacked up in the air I will hold the tire with my left hand and hit the knock off easily with just the weight of the hammer (but not lean in to it) till the knock-off stops spinning or the tire moves against the hammer. Once the car is on the ground I will hit it again once or twice with just the weight of the hammer and not lean in to it. I will then drive it a couple of miles (usually to the first stop of the drive) and then whack it again with one or two easy swings just using the weight of the hammer. I have heard it is bad news to fully tighten the knock off to the hub with the car on the ground static.

A whole lotta whackin goin on! /bcforum/images/%%GRAEMLIN_URL%%/hammer.gif
 
I read the VTR paper a few years ago and decided to test it out. I live on a circle with no stop signs about 3/4 mile long. I left the back left wheel hand tight and drove it around the circle 5 times. When I stoped the wheel was as tight as the others. Now I use a soft lead hammer and just give them a couple of taps when I put them on. I will say that I did the test with new wheels and hubs so I'm not sure I would trust ones that have been overtightened in the past.
