Torque/Tightening Specs

Recommended Posts

I’m frustrated in my efforts to source easily discernable torque specs for my 996 C4S. I’ve found them in a table format (i.e., without an accompanying illustration) in my CD of the Factory Shop Manual, but the difficulty is in translating the written description of the part that the bolt attaches to an illustration that employs the same wording. A typical listing reads:

“Control arm on side member M12 x 1.5 120 (89)”

But forming a mental picture of exactly what that “Control arm on side member” looks like as I’m under the car is challenging. I’ve attached a page from a Toyota shop manual which illustrates the assembly, and has the tightening specs of each threaded fastener shown alongside it. Is there any document (possibly the Bentley Manual) that provides the 996 torque specs in a similar fashion?

For the most part the determining torque value will depend on the quality (grade) of the bolt, the material you're installing the bolt into, and

whether you're lubricating the bolt with either Lock-Tite, anti-seize or installing the bolt dry. There are all sorts of charts on the internet that will help you determine

the correct torque settings. Here's one: https://www.swtc.edu/ag_power/diesel_engines/lecture/metric%20torque%20values.pdf

You can also get the same information in the 996 Bentley manual, although they are usually listed in small tables in the section referring to the repair at hand. The Bentley manual is available at the RennTech "store" at Amazon.
