New 6G1633 (2D3397) Chain G Replacement suitable for Caterpillar Equipment

The 6G1633 chain is a heavy‑duty traction or drive chain used in motor graders and other Caterpillar equipment to transmit power and support movement between gears, sprockets, or linkage components. It helps ensure synchronized motion and reliable performance under load.

Here’s a general guide for proper installation:

1. Turn off the machine, park it on level ground, and ensure it is safely supported.
2. Relieve any tension from the current chain (such as by loosening adjusters or tensioners).
3. Remove the old chain carefully, noting its routing.
4. Inspect sprockets, guides, and associated parts for wear or damage and replace if necessary.
5. Position the new 6G1633 chain along the correct path, making sure it seats properly in all sprocket teeth and guides.
6. Adjust chain tension per the specifications outlined in your service manual.
7. Test the movement to confirm smooth operation without binding.

The 6G1633 chain is typically used in Caterpillar motor graders and other heavy equipment where a link chain of this specification is specified for power transmission or track‑like applications. Compatibility varies by model and configuration, so verify fitment using your machine’s service documentation before ordering. Check your manual or reach out to Propel Parts for help verifying fitment.

Yes, the 6G1633 chain is engineered to meet or exceed OEM standards for strength, wear resistance, and dimensional accuracy. When installed correctly, it helps maintain consistent performance and withstand the heavy loads and impacts encountered in grading, hauling, or traction tasks.

Chains should be inspected during routine undercarriage or drivetrain maintenance. Look for signs of stretching, corrosion, broken links, or excessive wear on pins and rollers. Replace the chain if any of these issues are present to maintain reliable performance and prevent damage to sprockets or bearings.

Typical indicators include:

1. Chain elongation (measured stretch beyond acceptable limits)
2. Broken, cracked, or bent links
3. Uneven or jerky movement during operation
4. Excessive noise from the chain and sprocket interface

A quality chain like the 6G1633 ensures consistent power transfer, smoother movement, and reduced risk of unexpected failures. Using chains that meet or exceed OEM specifications improves machine reliability, extends the life of associated components (such as sprockets), and contributes to long‑term equipment performance and uptime.
