Flywheel to Torque Converter Bolts Torque Specs

The torque specification for flywheel to torque converter bolts is typically 80-90 foot pounds. This should be double checked in the vehicle’s service manual as some manufacturers may have specific requirements. The bolts should be tightened in a crisscross pattern and the process repeated several times until all of the bolts are tight and conform to the manufacturer’s specifications.

If there is an existing torque converter, it can be removed first by unbolting it from the transmission bellhousing before removing any of its mounting bolts from the engine block or flywheel. For safety purposes, all fastener hardware needs to be replaced with new components when reassembling parts on any engine or transmission component related project.

When it comes to replacing the flywheel on your vehicle, it’s important to use the correct torque specs when bolting the torque converter onto the flywheel. It is recommended that you use a torque wrench and tighten each bolt in a criss-cross pattern until they reach their specified torque rating of 35 ft-lbs for most vehicles. To ensure that you don’t damage any components, be sure to check with your vehicle manual for specific instructions regarding the bolts and other fasteners used during installation.

Quick Tip: Installing Torque Converter Bolts

How Tight Should Torque Converter Bolts Be?

When it comes to tightening the bolts of a torque converter, the amount of force you apply is important. Too much or too little can cause damage to the torque converter, and if done incorrectly, lead to costly repairs down the line. Torque converters generally require around 20 ft-lbs of torque when installing them.

However, always consult your user manual before applying any force as different manufacturers may have different specifications that should be followed precisely in order to ensure safety and proper operation. Additionally, make sure to use a quality torque wrench when tightening your bolts so that you get an accurate reading so you’re not over-tightening or under-tightening your bolts. When using a torque wrench for more precise readings, 10 ft-lbs is usually sufficient for smaller applications such as those found on most vehicles today while larger industrial applications may require up to 40 ft-lbs depending on their size and design requirements.

Taking all these precautions will help prevent problems from occurring later on due to improper installation.

What Should Flywheel Bolts Be Torqued To?

Flywheel bolts must be torqued to the manufacturer’s specifications in order to ensure proper engine operation and prevent premature failure. Generally, flywheel bolts should be tightened between 25-30 ft.-lbs. However, some engines may require higher torque settings such as 35-40 ft.-lbs.

, or even up to 50 ft.-lbs. for high performance applications; always refer to your vehicle’s specification manual before beginning any work on your car’s engine. It is important to follow the manufacturer’s instructions when tightening flywheel bolts, as too much torque can cause damage and/or accelerated wear.

Additionally, using a good thread lubricant (such as Loctite) will help reduce friction during installation and make it easier for you to achieve accurate results without over or under tightening the bolt heads.

How Much Play between Torque Converter And Flywheel?

When it comes to torque converters and flywheels, there is a significant amount of play between the two components. The torque converter itself is responsible for converting engine power into rotational motion. This motion then drives the flywheel, which converts that energy into useful work for the vehicle such as propelling the car forward or powering accessories like air conditioning and power steering.

In order to do this efficiently, it is important that there be just enough space (or “play”) between the two parts so that they can move freely without any binding or resistance from one another. If there is too much play between them, however, it will cause slippage and reduce fuel efficiency; if there isn’t enough play, then you won’t get optimal performance out of your motor either way. As such, finding an ideal balance between these two components should be a key component in keeping your car running smoothly and at peak performance levels throughout its lifespan!

What is the Torque on Flexplate Bolts?

When it comes to torque on flexplate bolts, there are a few different factors that come into play. The first and most important factor is the size of the bolt being used. Different sizes require different amounts of torque in order to ensure proper installation and prevent unnecessary damage or wear on the part itself.

Generally speaking, standard grade 8 bolts with 1/2″ threads should be torqued at between 35-45 ft-lbs for most applications. If you’re using a higher grade bolt, then you’ll need to adjust accordingly as these will usually have slightly higher torque requirements. Additionally, if your application requires more than just tightening down the bolt itself (for example, when there’s an extra washer or nut involved) then make sure you check the specific instructions provided by your manufacturer for how much additional torque should be applied in those scenarios.

Finally, always remember to double check any fasteners after installation – especially flexplate bolts – as even small discrepancies can lead to major issues down the line!

Flywheel to Torque Converter Bolts Torque Specs


350 Torque Converter Torque Specs

The torque converter in a 350 engine is typically rated at 250 to 300 ft-lbs of torque, depending on the make and model. It should be noted that exact specifications may vary by manufacturer and should always be checked before installation. Properly torquing your torque converter helps ensure it will perform effectively as well as potentially extend its lifespan.

Torque Converter to Flexplate Torque Specs

A torque converter to flexplate connection is an important part of a vehicle’s drivetrain system. To ensure the best performance and reliability, it is important to use the correct torque specs for this type of connection. The recommended torque specs for a torque converter to flexplate connection are typically between 35 and 50 ft-lbs.

It is also important to make sure that you use thread locker on all bolts during installation in order to prevent them from loosening over time due to vibration or other factors.

Torque Converter Bolt Torque Specs

When installing a torque converter, it is important to adhere to the manufacturer’s specifications for bolt torque. Most converters require that the bolts be tightened to between 25 and 30 ft-lbs of torque. It is also recommended that anti-seize compounds such as molybdenum disulfide be used on all threads when assembling the parts.

Following these guidelines will ensure a secure installation and optimal performance of your torque converter.


Overall, this blog post was a useful guide to correctly torque flywheel to torque converter bolts. It provided information on the amount of torque needed for each type of bolt, as well as tips and tricks to ensure successful installation. By following these steps and specifications, anyone can easily install their flywheel or torque converter with confidence that it will be secure and ready for use.
