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.
The most common symptom of a faulty rocker switch is the inability to turn the work lights on or off reliably. Intermittent operation or flickering lights can also occur. If left unaddressed, the switch may fail completely, leaving the operator without essential lighting for nighttime or low-visibility conditions.
Ensure the machine's battery is disconnected before attempting any electrical work to prevent short circuits. Make sure the wire terminals are clean and securely attached to the switch's posts.
Inspect the wiring and connectors associated with the work light circuit for any signs of corrosion or damage.
