The Torque Spec. Guide

Unless stated otherwise, torque specs are likely for dry , clean threads. If you plan to apply anti-seize, liquid thread lock or other lubricant or have oil residue on the threads then you need to use a wet torque value, generally 15% lower than the dry torque value to avoid over torqueIng the bolt Anything that acts as a lubricant will reduce the torque necessary to stretch the bolt to get the self lock affect and for same reason reduce the torque value where bolts stretches past the elastic range to the yield point. Likewise, any dirt on the threads or under bolt head will increase the torque required to stretch bolt to a self lock condition and can lead to under torqued bolts if you follow the dry torque value. Ideally you should have a washer under the bolt head so bolt head friction is metal on metal and not metal on paint

 

Just found this post today. Best post ever. Going to be doing a bunch of suspension work soon and this will come in real handy.

 

Thank you so much for this document! I am installing my lift kit and this is really the best and only trustworthy info I found on torques. Life saver!

 

Incredible.. Thank you so Much !

 

I tried a quick search and didn't hit on it, probably not using the right terms.

Just got some bed steps (not sliders, just the crappy steps for my kids) and trying to locate proper torque for them (into the recessed threaded spots near what I think is called the pinch weld). Also curious if anti-sieze is good or the bolts should be left dry.

 

The OEM ones I bought said 14 ft lbs. Nothing has exploded yet. I did not use anti-seize and had no issues when I needed to remove them over a year after install.

 

Cant imagine those are too critical. Nice and snug would be good I think. If you are anywhere near the salt belt, I would use anti-sieze yes

 

Does anyone have the torque setting for the front subframe support bolts or know what page # it is in the service manual? TIA!

 

Going off one of my screenshots I took when I was replacing those, if those are 17mm bolts then they should be 33ft lbs

 

Most handy!

 

This guy deserves a medal for this. I can't count how many times I've visited this thread for reference. THANK YOU!!

 

If there was an award for the most visited thread with the least amount of posts per view....yup....this one has it hands down.

 

Want to back myself up here. About to drop and clean the transmission pan and filter. Pan is attached to the case with 22 10mm bolts.

The torque spec appears to be 7.4 Nm or 65 INCH pounds. My torque wrench has no inch pound markings only foot pounds, and lowest Nm marking is 13.6. This appears to be an incredibly low torque setting. Should I just hand crank these and maybe go a fraction of a turn beyond with my 10mm socket?

 

That does equal to about 5.25 ft/lbs.....even that seems a little small. Which page did you find that on in the first post?

 

On the original post, had to do a text search to find it:

 

Just wanted to say thank you! I'm finally able to start wrenching on the Tacoma and having this pdf loaded up on all my devices has been very helpful.

 

Good on you for accepting the torque value (and not arguing it).
Oil pan bolts typically use very light torque. In fact the majority of oil leaks at the pan are from over-torqueing the bolts. Far too many shadetree mechanics think more torque is better. Definitely not the case with thin stamped metal oil pans!
The gasket is to stop the leaks, not the bolt snugness.

Nothing wrong with investing in an "inch-pound" torque wrench. It may not be the most used tool in your box, but it may be one of the most important ones.

 

I did end up buying one, and the transmission pan is still the only location I’ve used it. But that’s ok, any excuse to buy a new tool.

 

I've got four toque wrenches. Don't have them in front of me and I'm drawing a blank on their exact ranges.

One 1/4" drive, is in inch-pounds, and tops out at 200 (I think).
Two are 3/8" drive, in foot-pounds up to 80 & 100. One is click type and the other is dial indicating.
Last one is a monster at 40 inches long, 3/4 drive (which I adapt to 1/2"), and reads up to 350 foot-pounds. I have maybe 3 sockets in the 3/4" drive size, but sitting pretty with a full 1/2" set.

I learned early on as a Crew Chief on helicopters just how immensely important proper toque is! That lesson never left me and I look-up and use the proper torque value for every bolt I touch. (No kidding, damn near every one.)

 

I’m the same way, I look for a torque value before reinstalling just about any bolt on the truck. Came from the aviation community as well, and although I was a flyer I did a stint in the aviation department and I’m familiar with QA callouts for torque settings and the importance of such things. We had outstanding maintainers.
