  • Remove the Servo motor and then unbolt, and lift one end (use a chain fall) to expose the under carriage. Remember to block the lift so that it cannot fall while you perform maintenance.
  • Wash down and remove any sediment. Don't wash dirt under the steel band that protects the internal mechanism.
  • Remove the end covers on the linear actuators and check if the motor belts need tightening.
  • Examine the cable management system for abraded cables or other indications of wear.
  • Remove the top covers of the linear actuators and check the ball screws to see if they need cleaning or additional lubrication.

The Core Splitter is a very robust piece of equipment and only needs a full service every five years or so. The Core Splitter should only be dismantled under the direct supervision of the Lab Officer or their appointed designee. Have the ship's electricians isolate the power to the Core Splitter before beginning the work.
The following images document, in part, the full dismantling of the Core Splitter in 2015. Additional images are in the Uber Saw folder in IODP_Share.
