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 Why is using the correct torque specifications important for the DQ500 transmission?
Why is using the correct torque specifications important for the DQ500 transmission?
Using the correct torque specifications is crucial to ensure proper clamping force and prevent damage to the transmission components. Over-tightening bolts can cause stripping of threads, deformation of parts, and failure, while under-tightening can lead to leaks, vibrations, and component loosening. Correct torque ensures the longevity and reliability of the DQ500.
Q2 Do torque specifications change if I use aftermarket bolts?
Do torque specifications change if I use aftermarket bolts?
Yes, torque specifications can change significantly if you use aftermarket bolts. Different materials, thread pitches, and coatings can impact the required torque for proper clamping force. Always refer to the manufacturer's specifications for the specific aftermarket bolts you are using. If no specs are provided, consult with the bolt manufacturer or a qualified mechanic.
Q3 What happens if I accidentally over-torque a bolt on the DQ500 transmission?
What happens if I accidentally over-torque a bolt on the DQ500 transmission?
Over-torquing a bolt on the DQ500 can lead to serious issues, such as stripped threads in the transmission case or the bolt itself, potentially requiring a more involved and costly repair. In some cases, you might also damage the components that are held by the bolts. It's critical to back off the over-torqued bolt and inspect for damage. Depending on the damage, you may need to replace the bolt, the surrounding part, or use thread repair techniques.
Q4 Should I replace transmission bolts after removing them?
Should I replace transmission bolts after removing them?
It is generally recommended to replace certain types of bolts, especially those that are torque-to-yield (TTY) or stretch bolts, whenever they are removed. These bolts are designed to stretch slightly upon tightening and cannot be reused. TTY bolts are commonly used in critical areas like engine mounts or certain transmission components. Refer to the factory service manual for specific replacement guidelines. For bolts that are not TTY, they can sometimes be reused, but a careful inspection of the bolt threads is essential.
Q5 Do I need to use thread locker on the DQ500 transmission bolts?
Do I need to use thread locker on the DQ500 transmission bolts?
Yes, some bolts in the DQ500 transmission system may require thread locker depending on their specific location and function. The factory service manual will indicate which bolts need a thread locker like Loctite, and which type to use. Using the wrong thread locker or applying it improperly can cause issues and lead to loosening or incorrect clamping. Some areas, such as where external vibration is present, will benefit from thread locking agent application
