Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing circuit breaker may not trip during an overcurrent event, leaving the electrical system vulnerable. Alternatively, it might trip without cause, leading to unexpected power loss. Continued operation with a faulty breaker risks damage to wiring harnesses and sensitive electronic components.

Installation Tip

Ensure the battery is disconnected before attempting any electrical work to prevent short circuits. Do not force the breaker into its mounting socket; it should fit snugly without excessive pressure.

Service Note

Inspect all associated wiring and terminal connections for signs of corrosion or damage when replacing the circuit breaker.
