Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Prevention:
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Prevention:
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Prevention:
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Prevention:
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Prevention:
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Q2 What tools should I use to ensure accurate torque application?
Q2
What tools should I use to ensure accurate torque application?
Use a calibrated torque wrench in good condition. Digital torque wrenches may provide more precise readings than traditional click-type wrenches.
Q3 How can I prevent overtightening bolts?
Q3
How can I prevent overtightening bolts?
Always start with a lower torque setting and gradually increase it until the specified value IS reached. Overtightening can damage threads and lead to safety issues.
Q4 What IS the correct procedure for tightening bolts in a sequence?
Q4
What IS the correct procedure for tightening bolts in a sequence?
Follow the Mercedes-Benz specified bolt tightening sequence to ensure even distribution of force. Tighten bolts in a star pattern, gradually working from the center outward.
Q5 Do I need to re-torque bolts after a certain period of time?
Q5
Do I need to re-torque bolts after a certain period of time?
Refer to Mercedes-Benz service intervals for specific recommendations. Generally, bolts in critical areas may require re-torquing after a few thousand miles to maintain proper tension.
Q6 What are the consequences of improper torque application?
Q6
What are the consequences of improper torque application?
Under-tightening can lead to loose bolts and potential component failure. Overtightening can damage threads, cause bolt breakage, or deform components.
