Clocking a Gear Reduction 39MT Starter | Delco Remy Product Tech Tip

The Delco Remy 39MT heavy duty starter rotatable flange models were designed specifically to improve service flexibility and part number consolidation. The new service models provide full industry and application coverage, easily replacing competitive units.
The rotatable mounting flange models can be rotated, or clocked, to take the place of many other fixed mounting flange starters. By utilizing these part numbers, you can reduce inventory part numbers while maintaining coverage for virtually all of the applications on the road today.
There are three key steps to keep in mind when clocking the starter:
• Obtaining the correct solenoid position
• Repositioning the Integrated Magnetic Switch (IMS)-if required
• Positioning the drain holes
You perform these steps to clear any obstruction that may hinder the starter from being mounted, such as the frame rail, bell housing, mounting brackets, hoses, lines or any other object that may be in or near the mounting area, and allow the starter to drain
condensation properly.
This Tech Tip video explains the three key steps in detail.
