Torque wrench help in Western Mass?

Also, the vast majority of torque wrenches only measure in one direction.. I have one that goes both ways (no pun intended) for a few reverse threaded applications but that's about all I use it for.. I also use it for checking breaking torque when loosening cylinder head bolts on problem engines..

those are called "breaker bars"

torque wrenches are ONLY for re-assembly. when putting nice, clean parts back together.

Dude, in this case, you couldn't be more wrong. It's VERY important to use a torque wrench to remove the glow plugs. The maximum torque for removing 10mm glow plugs is 25 ft. lbs. Any more and the glow plug will break.

Then how would you torque left handed nut and bolts, all my torque wrench's will go both ways.

The reason for using a torque wrench for removing the glow plugs is not to break them off. Don't use more than 25 foot pounds for removing them.

BUT you could still break one!!

WE need it too for the '65 Barracuda YEP LH threads on the drivers side..

What brand of glowplug breaks at 25 ft-lbs? I will avoid purchasing them..

So far I've never used a torque wrench to remove a glow plug... I've probably changed the glowplugs on 3000 engines LOL... I can understand the need for someone who doesn't turn a wrench every day to use one when loosening them since they probably have no idea what 25 ft-lbs feels like until it breaks...

The best advice I can give is to use a 1/4" drive short ratchet and an 8-12" extension.. 25 ft-lbs is pretty hard to achieve with a 4" long ratchet...

Well seeing how my 1/2 torque wrench cost $350 and my 3/8 cost $250. I never never never use them to take things apart.

Don't want destroy expensive wrenches. Carefully use regular wrenches or a breaker when needed.

Never broken off a GP. In fact my worst broken bolt was thee turbo return on my alh. I was useing a 1/4 ratchet. And not even torquing it hard.

Beru used to have a document on their website that stated:

"Do not exceed the maximum release torque – 8mm GP-20Nm, 10mm GP-35Nm, 12mm GP-45Nm."

They no longer have the document (TI04_e.pdf) on their website... (If anyone has saved a copy, it would be nice to have access to it...
