garmon head bolt torque specs anyone?

So I got raped on getting snap on tourqe plus angle wrenches? Please show me where I can get them cheaper. I'm a mechanic so my tools are my livelihood and because if that I buy the best. They let me know the tourqe of the bolt to the 0.1th and gives me a live reading. Have fun with you 100$ wrenches....

f that is right

harbor freight "pittsburgh brand" rachet box ends have worked on 3 motor drops

the torque wrench i bought worked once

bought a snap on tq wrench - never looked back - not digital, but have the small adjust knob on the side




I bought it to do my head bolts, nothing else. I'm pretty sure harbor freight are within +/-5%..

Maybe forest will chime in, he use to calibrate tq wrenchs IIRC.

And last all that matters if you use slow and steady pull.

Been pushing 60-70psi for over 2 years. I'm happy with that.
 
If you are using a click type wrench, take them to about 130 and leave it be, the sudden jerk you get from the click is no bueno on a bolt you are trying to keep from stretching.

You said they cost you "$600 a pop" correct? I can get a snap-on 1/2" techangle for under $400 through my dealer so that's why I made that comment (regular techwrenches are cheaper which is what I have). To hell with the techangles, I'll use a paintmarker for that kinda money lol.

The only reason I have snap-on techwrenches is because cummins calibrates them every 6mo for us. Half the time new wrenches fail cal also, which is why I bought Proto clickers for backup $.02
 
I bought them a few years ago when I got out of tech school they have never failed me yet and honestly don't rember how much I paied for them LOL. which cummins do you work for I worked for cummins rocky mountain.

I have always wondered about this..... wonder how much difference it really does make.
 
I've got an older Klein Click type. It gets calibrated everyday, sometimes twice a day. I'd put it against every torque wrench out there.

A $80 craftsman wrench is adequate for most everything.

Not much at all, but it depends how you yourself pull the click type, if your the kind that goes slow and easy your alright, if your the other type you could have issues.

An on-sale $15 1/2" Harbor Freight torque wrench did the bolts in my Junker Drag Truck. The torque setting only goes up to 150 ft lbs, so I had to guesstimate the torque on my last two torque steps up to 155-160 ft lbs.



Still holding fine with no signs of a blown headgasket at 75 psi boost and 25* timing.

I acknowledge that there are much better tools out there, but for my particular project, the $15 torque wrench made the most sense.
 
I own a craftsman digital bout 250 but they are dead on to .3+/- I use the dog crap out of it vie owned it two weeks and used it 10 times more than my old clicker wrench
 
New bolts, apply some grease to the threads.
Torque to 50, 75, 100 ft/lbs
Let cool for 30 minutes.
Go up 5ft/lbs at a time every 30's minutes until you reach 150/155ft lbs.
Take care to note if the bolts start stretching around 145/150ft lbs. The last time I torqued a set they started stretching at 150 so I stopped there.

So when doing this do you back the bolt off between each increment before you retighten, do you take the whole bolt out and regrease it before going up to the next increment, or do you tighten it more without backing it out or removing it each time?
