Glow plug relay connection bolt torque

[SnowDrift]

The 25 ft. lbs. from the torque spec. thread for this is for the electrical connections, correct? Not the hold down bolts. This sounds right, from when I did this recently, but couldn't quite remember and didn't want to strip the studs out.

I am not sure but there are a few people who tighten it too much and it ruins the relay.

I did not remember I put a torque wrench when I replaced mine a while back.

I just snug them down by feel.

I thought I remember seeing a spec but it was inch pounds not feet

Not so good. I used to break off 3/8 bolts torquing them down to feel. The ratchet never slowed down and they would just break

Use a shorter 1/4" ratchet/socket/torque wrench instead of 3/8".

Umm, I hope you weren't using an air rachet! I just use my fingers around the head of my 3/8 drive rachet and use my thumb and pinky to twirl the rachet, not the handle, to reduce the torque applied. The free swinging mass of the handle on my 3/8 acts like a mini-impact. Compresses the split lock washer nicely, haven't broken a stud and haven't had a ring terminal loosen since I put a new GP relay on back in Jan 2011.

It's all a practice thing. I haven't turned wrenches for a few years, but was teaching my older boy last month how to use different styles of torque wrenches. When I tightened down with a ratchet and had him use a beam style to loosen it I questioned the tool, because I used to be crazy accurate. I ment to tighten to 75lbs, but went to 82. I did a "35" and it was 38 using another torque wrench to check it. Kills me, I was always within 1 pound all the way to 250 lbs range, and figuring the 1% standard error rule- that was something I showed off with to friends.

It's a practice thing like shooting or playing an instrument is. Torque wrenches recal rule is once a year, everytime dropped, or 1,000 cycles.

Want to get better- waste $15. Buy a harbor freight throw away one, compare it to your real one to make sure it's in spec, double check your monthly. Most HF are 5-6% off new and 10% off in a year I learned when working for a large company that only bought HF tools when I started there (into my 2nd year I had them off the crack). Use the HF one as a ratchet for everything you do for a while. You'll get the feel real soon. Then you have a loaner for the neighbor who doesn't understand to take care of stuff. You'll also learn why you don't buy accurate tools at HF.

On the air tool usage, I get close with them but worked with guys that had a feel for it and can be within a couple pounds everytime using impacts. Usually grey hair and very faded toolboxes was involved

Snug it. No tq spec needed.

 

[SnowDrift]

It's snug, but not broken

Like my wife

Your not doing it right then.
