DESCRIPTION
A machine general-purpose grease (lithium, calcium grease),
B permanent grease for heavily loaded elements with addition of MOS
2
or
graphite
C anticorrosion preparation in aerosol
D ordinary machine oil, silicon grease in aerosol
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
leaf 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 aerosol
preparation (for lubricating guides, locks etc. - see table) can be also used. Sliding surface of
leaf spring and leaf spring pin should be lubricated according to recommendations contained
in table (5.4).
Parts to be lubricated with machine oil should be wiped with dry clean cloth and then a small
quantity of oil should be applied to their surfaces (using oil can or brush). Wipe off excess oil.
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.
During trailer operation, the user is obliged to observe lubrication instructions according
to attached lubrication schedule.
