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 the fuel bolt on a 1982-1987 Dodge Charger?
What is the recommended torque specification for the fuel bolt on a 1982-1987 Dodge Charger?
The recommended torque specification for the fuel bolt on a 1982-1987 Dodge Charger is typically 18-22 ft-lbs (24-30 Nm). Always refer to the vehicle's service manual for the exact specification, as variations may exist depending on the engine model and fuel system configuration.
Q2 What happens if I over-torque the fuel bolt?
What happens if I over-torque the fuel bolt?
Over-torquing the fuel bolt can damage the threads on the fuel rail or the bolt itself, leading to fuel leaks or component failure. It can also deform the sealing surfaces, compromising the fuel system's integrity. Always use a calibrated torque wrench to avoid over-tightening.
Q3 How often should I check the torque on the fuel bolt?
How often should I check the torque on the fuel bolt?
The torque on the fuel bolt should be checked during routine maintenance or whenever the fuel system is serviced. If you notice any fuel leaks or unusual engine performance, inspect the fuel bolt torque as part of your troubleshooting process.
Q4 Can I reuse the fuel bolt after removal?
Can I reuse the fuel bolt after removal?
Reusing the fuel bolt is generally acceptable if it is in good condition and the threads are not damaged. However, it is recommended to replace the bolt if it shows signs of wear, corrosion, or deformation. Always use a new sealing washer or gasket to ensure a proper seal.
