Hull unit lubrication
The hull unit is fully lubricated when it is installed on the vessel,
and this is also checked during installation. During normal
conditions, the lubricants applied will last for a long period of
time.

Note
Additional lubrication of the hull unit must only take place
when it is required.
Observe the following procedure. The numbers refer to the
lubrication points on the illustration.
1 Inspect the ball bearings on the top and the bottom
of the hoist/lower screw (1). Grease only if required
using normal ball bearing grease.
2 Inspect the hoisting spindle (2). Lubricate only if
required using Tonna Slideway Oils S68 or similar
grade lubricant. If too much lubricant is applied to the
hoisting spindle, you may experience a lot of spillage
when it rotates in high speed.
3 Inspect the top of the transducer shaft sleeve, and
check for water penetration. Check the appearance of
grease on the transducer shaft.
4 If you detect a water leakage, or if the transducer shaft
is dry, you may add extra grease.
a Open the pressure release plug (A).
b Add extra grease into the shaft sleeve through the
grease nipple (3).
c D
o not add excessive amounts of grease. The total
capacity of the shaft sleeve is less than four kilos.
d Use one of these grease types, or an equivalent
type with similar characteristics:
• Esso Cazar K1
• Shell Rhodina EP2
• Shell Alvina EP2
WARNING
When you top up the shaft sleeve with oil, you
must open the pressure release plug to avoid
damage to the shaft bearings.
