Can You Still Get Replacement Parts for Legacy NightHawk, Tercel, and Rubicon Motors?

The NightHawk motor, along with its later versions under Tercel and Rubicon, has built a reputation for durability and performance in drilling operations worldwide. While these motors are no longer in active production, many operators still run them every day—especially in markets where proven, reliable designs are valued over untested alternatives.

If you own or operate one of these motors, finding NightHawk motor parts, Tercel motor parts, or Rubicon motor parts can be a challenge. OEM inventories are limited, and aftermarket replacements often fail to match the original specifications. That’s where Commander Downhole Technologies can help.

The Legacy of NightHawk, Tercel, and Rubicon Motors

The NightHawk design started as a rugged lower end built for high torque and long run times. Over time, ownership of the design passed through Tercel Oil and Gas and later Rubicon Oilfield International, each making updates and refinements to the model.

Today, these motors are still in service in the Permian Basin, across the U.S., and in international markets. Operators keep them running because:

• They have a proven track record in multiple formations.

• Their components are compatible with existing fleets.

• Maintaining a legacy motor can be more cost-effective than replacing it entirely.
