Drake-recommended replacement
Direct replacement.
| Preferred item | Description | Applies when |
|---|---|---|
| 9907-014 | Improved standard 2301A speed control (Caterpillar part number 131-5453), fixed and variable speed versions | Recommended replacement; customer wiring to control terminals differs due to internal control design differences (see App Note 51191 / manual 82020 for wiring changes) |
Note: Not a plug-and-play swap: internal control design differs, so customer terminal wiring changes (droop potentiometer slider moves terminal 14->13, CW lead 13->14; rated/idle contact moves to terminals 2 and 5; remote potentiometer assembly replaced by a single 10-turn 1K potentiometer). Refer to Woodward manual 82020 and App Note 51191 for the full retrofit wiring.
