Torque Values ???

Ok Please explain torque values as well at least Harley uses them. They list things in the service manual like:
stabilizer link screw 25 - 35 ft lbs
rear brake hose clamp screw 30 - 40 in lbs
just to name a few. My question is where do I go with the spread, high low or the middle. I will be doing a lot of work on the bike next weekend and could really use some help in clearing this up.

Thanks in advance Be Safe JIM

I always shoot for the mean setting. That is machinist talk for going for the mid point.

The spread is min/max specification. Min. being the minimum torque value for the fastener to stay fastened. Max is the value above which there is a risk of damaging the fastener. At least that's how my mechanical engineer riding buddy explained to me.

Short answer: use the midpoint between the two values.

I always went for the midpoint, I figured it was safer that way.

considering that most of the Torque wrenches I've tested were so far off they were useless, I guess if you go for the mid-point, you may be in the ball park. Don

Midpoint is good, like everyone is saying...

Keep this in mind
Most Torque values are set -up for dry.
If you lube the bolt, nut, whatever it will change the value slightly.
Also, general rule is to torque the nut end when-ever possible not the bolt.
