What is a pintle bearing? – Roadlesstraveledstore

Clearance in the neck bearing can be measured after the rudder is overhauled. Unless other wise the measurement is carried out using a feeler gauge. The standard clearance is 4.0 mm, If the clearance exceeds 5.0mm, the bush should be replaced. Actually the wear down of the neck bearing bush is smaller than the pintle. What is bumper pull?
