and I have question. to open drain nut? something i have 3/8" drive ratchet. also when I tight it should be 25 ft torque.

so.. do I have 3/8" torque wrench? i already have 1/2' torque wrench...

and why they use drive ratchet? if it need torque wrench anyway? I mean why they also don't use torque wrench to open drain nut

 

You can guess 25 ft lb... if you want to use your torque wrench just use an adapter, it's not exact but it's just a drain plug. You don't need a torque wrench 25 ft lbs is a little past hand tight.

 

Do you have a 3/8" torque wrench? I don't know, do you? I'm going to guess no.

A ratchet driver is used instead of a torque wrench because its what is was designed for. A torque wrench is a calibrated tool, not a breaker bar.

 

Just make it tight.

 

Exactly.....DON'T use your torque wrench as a breaker bar, you should only use it to torque something after it has already been tightened up!

 

O.. I didn't know that.. Thanks
