Description
RAYMARINE ST4000 Mk2 Wheel Drive Replacement Belt – A18083 is the replacement internal drive belt for the grey ST4000 Mk2 wheel-drive mechanism. It is a practical service part for a wheel pilot that slips, has a broken belt or requires preventative overhaul, and it is also relevant to the wheel-drive hardware used with EV-100 Wheel Pilot systems.
Features
- Replacement internal belt for the ST4000 Mk2 grey wheel-drive assembly.
- Restores mechanical power transfer when an original belt is worn, stretched or broken.
- Useful spare for cruising vessels that rely on a wheel pilot for routine steering assistance.
- Compatible with the Mk2 wheel-drive design used in later Raymarine wheel-pilot installations.
- Model-specific service part that avoids replacing the complete drive when only the belt has failed.
This belt does not fit the earlier black-cover ST4000 wheel-drive version. Verify the wheel-drive generation and housing style before ordering.
