Frequently Asked Questions
Q: What is the CT 913998 soft recovery diode used for?
A: The CT 913998 is a Caterpillar OEM soft recovery diode designed for electric lift truck applications. It functions as a critical electrical component in the trucks control and power management systems, protecting the electrical circuit from voltage spikes and reverse current conditions.
Q: Which equipment brands and systems is the CT 913998 compatible with?
A: This diode is compatible with Caterpillar electric lift trucks and Daewoo electric material handling equipment. It fits various Caterpillar and Daewoo forklift control systems and power modules. Verify your equipments electrical diagram matches OEM part number 091-3998 before ordering.
Q: What are the cross-reference and equivalent part numbers for CT 913998?
A: CT 913998 is equivalent to OEM part number 091-3998 and Daewoo part number DW913998. When sourcing replacements, confirm the exact part number matches your equipment documentation, as similar diode types may not be direct substitutes.
Q: What symptoms indicate that the CT 913998 diode needs replacement?
A: Common failure indicators include intermittent power loss during truck operation, repeated circuit breaker trips, erratic control system behavior, or burned-out electrical components downstream. If the trucks main contactor fails to engage reliably or the battery charger shuts down prematurely, the diode may be faulty.
Q: Is the CT 913998 compatible with other electric truck manufacturers besides Caterpillar and Daewoo?
A: No. The CT 913998 is engineered specifically for Caterpillar and Daewoo systems. Electric truck manufacturers including Toyota, Crown, Raymond, and Hyster use different diode specifications and mounting configurations. Using a non-compatible diode can cause electrical faults or equipment damage.
