Apr 12, The pintle bush clearance for top and bottom pintles are to be measured using long feeler bushleaning.bar allowable pintle bush clearance is mm for pintle dia up to mm.
For dia exceeding mm the clearance is proportionately increased. If the clearances are excessive the bushes are to be renewed after dismantling the bushleaning.barted Reading Time: 10 mins. Dec 04, Re: Measuring rudder pintle bearing clearances. I was watching this job recently in DD (single pintle, semi-balanced) and the welded cover (actually this was a bolted and jointed cover) was removed.
It is much easier and accurate this way i.e. you can see that you are getting a true clearance and not measuring a 'lip' in the bush or liner if. Jul 29, For a newly built ship, the standard clearance is mm. For a ship in service, Maximum allowable clearances between pintle and bush is 6 mm.
IF the actual clearance exceeeds 6mm, the apple falling from tree which motion should be renewed. 3) Neck bearing Clearance in the neck bearing can be measured after the rudder is Estimated Reading Time: 8 mins.

Nov 26, Far in service acceptable clearance we feel about 1/64" clearance per 1" of diameter of pintle up to 1% of diameter would be acceptable for another two years of service.

Jul 27, The rudder stock/pintle’s clearances and the bearing are recorded in the longitudinal direction (F-A) and the transverse direction (P-S). The clearance is typically recorded using feeler gauge or inside and outside micrometers whenever the rudder stock/pintle is dismantled and removed. Initial (Minimum) Rudder Bearings Clearance.
