Faults and Fixes
Why will the gearbox not engage ahead or astern?
Before blaming the internals, look at the control side: cable adjustment, the coupling and gearbox oil level. Those three account for most cases.
Why it works this way
Where the internals are involved, metal particles show in the oil — which is why the gearbox oil is inspected as part of the engine room survey rather than only the shift action.
