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 are the torque specifications for the F5A transmission bolts on a 2004-2011 Mitsubishi Endeavor?
What are the torque specifications for the F5A transmission bolts on a 2004-2011 Mitsubishi Endeavor?
The torque specifications for the F5A transmission bolts vary depending on the specific bolt and location. For example, the bellhousing bolts typically require 55-65 ft-lbs, while the transmission pan bolts require 7-9 ft-lbs. Always refer to the manufacturer's service manual for precise torque values and tightening sequences.
Q2 How often should I check the torque on my F5A transmission bolts?
How often should I check the torque on my F5A transmission bolts?
It is recommended to check the torque on your F5A transmission bolts during routine maintenance, such as during an oil change or transmission fluid replacement. Additionally, inspect the bolts if you notice any unusual vibrations, leaks, or noises, as these could indicate loose bolts.
Q3 Can I reuse the transmission bolts after removal?
Can I reuse the transmission bolts after removal?
While some transmission bolts can be reused, it is generally recommended to replace them, especially if they are torque-to-yield (TTY) bolts. Reusing TTY bolts can compromise their integrity and lead to improper torque application, potentially causing leaks or component failure.
