Frequently Asked Questions
What is the 6V3918 bolt used for?
The 6V3918 bolt clamps components together with a controlled, repeatable force that holds them aligned under load and vibration. Reliable bolts are fundamental to a secure assembly.
How do I install the 6V3918 bolt?
To install the 6V3918 properly, prepare the area first and confirm the result afterward. Use these steps:
- Shut the machine down and isolate power before service
- Clean the threads and mating faces so debris doesn't affect clamp load
- Inspect the threaded bore and the 6V3918 for damage
- Start the bolt by hand to avoid cross-threading
- Torque it to the value and sequence listed in your service manual
- Re-check torque after the first operating cycle if the manual advises
Which Caterpillar machines is the 6V3918 compatible with?
The 6V3918 is matched to particular Caterpillar equipment, so always verify the application against your parts reference before purchasing. Or reach out to Propel Parts for help verifying fitment.
Does the 6V3918 bolt meet performance standards?
