How is a bent shaft identified and what does it lead to?
A bend is not visible directly; it shows itself as vibration, accelerated wear in the cutless bearing and increased drip at the stern gland. The shaft is therefore measured together with coupling alignment and bearing clearance.
Why it works this way
Caught late, unusual bearing wear ends as water ingress through the gland. That is the sequence that turns a measurable fault into an expensive one.
