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.
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.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
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.
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.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What is the recommended torque specification for exhaust bolts on a 2016-Present Ram 5500?
What is the recommended torque specification for exhaust bolts on a 2016-Present Ram 5500?
The recommended torque specification for exhaust bolts on a 2016-Present Ram 5500 is 35-40 ft-lbs (47-54 Nm) for the exhaust manifold bolts and 20-25 ft-lbs (27-34 Nm) for the exhaust pipe flange bolts. It's essential to consult the repair manual or the manufacturer's website for specific torque values, as they may vary depending on the engine type and exhaust system configuration.
Q2 Why is it important to follow the recommended torque specification for exhaust bolts?
Why is it important to follow the recommended torque specification for exhaust bolts?
Following the recommended torque specification for exhaust bolts is crucial to ensure the exhaust system is properly sealed and to prevent damage to the engine, exhaust components, and surrounding structures. Over-torquing can lead to stripped threads, while under-torquing can cause leaks and decreased performance.
Q3 How often should I inspect and maintain the exhaust system on my 2016-Present Ram 5500?
How often should I inspect and maintain the exhaust system on my 2016-Present Ram 5500?
