5.7 TRAILER LUBRICATION

Trailer lubrication should be performed with the aid of a manually or foot operated grease
gun, filled with recommended grease. Before commencing work insofar as is possible
remove old grease and other contamination. Remove and wipe off excess oil or grease.
During trailer operation, the user is obliged to observe lubrication instructions according
to attached lubrication schedule.
Change of grease in hub bearings should be entrusted to specialised service points,
equipped with the appropriate tools. According to the recommendations of the axle
Manufacturer, dismantle the entire hub, remove the bearing and individual sealing rings. After
careful washing and inspection, mount lubricated elements. If necessary, bearing and seals
should be replaced with new parts. Lubrication of axle bearings shall be performed at least
once in 2 years or every 50,000 km. In the event of intensive use, lubrication should be
performed more frequently.
Before beginning to grease leaf springs remove contamination, wash with water and leave to
dry. Do not use pressure washers, which may cause moisture penetration between individual
suspension spring plates. Absorber plates should be lubricated using an agent having both
anticorrosion and lubricating properties, it is recommended to apply on outer leaf spring
surfaces very thin layer of lithium or lime alkali grease. For this purpose, silicone spray (for
lubricating of guides, lock etc. see table) can be used. Sliding surface of suspension spring
and suspension spring pin should be lubricated according to recommendations contained in
table (5.6).
In order to lubricate the hook frame guiding surfaces, first remove old grease and
accumulated contaminations and then, apply grease using a brush. Remove and wipe off
excess oil or grease
Parts that should be lubricated with machine oil should be wiped with dry clean cloth and
then a small quantity of oil should be applied to surfaces (using oil can or brush). Wipe off
excess oil.
