GENERAL MAINTENANCE
This section covers hull and machinery maintenance.
6.1
PERIODIC CHECKS
Perform periodic checks in accordance with Table 2. The items are arranged such that the table can be
reproduced and used as a check list. Item numbers have been assigned to assist in programming your checks.
The meaning of each letter follows:
E = each use
D = daily
W = weekly
M = monthly
Q = quarterly
R = as required by the manual
6.2
PREVENTATIVE MAINTENANCE
a)
Preventative maintenance generally refers to the application of lubricants, removal of corrosion, tightening of
fittings, etc. It is maintenance performed to prevent equipment failure. By defining it this way, we include
certain corrective maintenance procedures which will stop a small problem from becoming a big problem. As
an example; if during checking belt tightness a worn bearing is observed, replace the bearing before it fails.
Murphy's law says that the bearing will fail no less than a mile from shore.
b)
Preventive maintenance on machinery is covered in the equipment manuals.
c)
A trailer will benefit from six basic preventive maintenance tasks: (1) a fresh water washdown after
submersion in salt, brackish or polluted water, (2) grease “bearing buddies” after each use to push out water,
(3) a few drops of oil on winch and trailer jack shafts each week, (4) repack bearings quarterly, (5) top off
brake system hydraulic oil quarterly, (6) adjust brakes quarterly.
d)
Zincs on the hull, shafts and rudders, as applicable, should be replaced everytime the vessel is hauled for
recoating or when the zincs appear
