Greasing And Oiling - DG Flugzeugbau DG-1000T Maintenance Manual

3.3 Greasing and oiling

A The contact surfaces of the canopies to the fuselage are to be rubbed with
colourless floor-polish (canopy and fuselage side) to reduce grating noise in
flight. Polish at the beginning of the flight season and then every month.
B Once a year your glider should be carefully checked and all bearings,
including control surface hinges, should be cleaned and greased if necessary.
The various greasing points are as follows:

Aileron drive connections at the inboard aileron.

Airbrake drive connection - in airbrake box, also grease the brake paddle
pivots.

Remove the access panels on the left hand cockpit walls and grease all
the pushrod guides, but not those with Teflon linings, note see below.

Remove the baggage compartment floors and open the baggage
compartment rear cover to grease all bearings.

Open the access panels (2 in the front and 2 in the rear cockpit). In the
rear cockpit you have to remove the height adjustable seat pan first.
Grease all accessible bearings (ball bearings and rod ends with universal
bearings)

Remove the control column boots and grease all the bearings associated
with the control columns.

Grease the rudder pedal adjustment slide.

Oil all hinge points on the undercarriage in the undercarriage box.

Clean and grease all control surfaces hinges.

Clean and grease the control hook ups for ailerons, airbrakes and elevator
control.

Clean and grease all pins and bushes of the wing and tailplane
attachment.

Clean and grease the lower ball fitting of the gas strut at the front canopy
(if installed).
Note: The greases we recommend are lithium based pressure-resistant anti-
corrosion greases or lithium-soap greases (multi-purpose greases for rolling
element bearings).
Use thin engine oil eg. SAE 5W30
Caution: The sliding guides of the following parts are made from Teflon and
should not be greased:
 Landing gear controlhandle 5FW39 on 5St68/2
 Airbrake control handle 5St69 on 5St68/1
If these parts have been greased inadvertently you have to disassemble the parts
and to clean them completely with Acetone.
