Shimmy Damper Servicing at every 100 hours:
 (1) Remove the shimmy damper.
 (2) While you hold the damper in a vertical position with the fitting end pointed down, pull the fitting end of the damper shaft to its limit of travel.
 (3) While you hold the damper in this position, fill the damper through the open end of the cylinder withhydraulic fluid.
 (4) Push the shaft up slowly to seal off filler hole.
 (5) Clean the damper with solvent. Make sure that the shaft comes out through the filler hole until the damper is installed on the aircraft.
 (6) Install the damper on the airplane.

Shimmy Damper Servicing (Lord Shimmy Damper)
Lord Shimmy Dampers do not need special servicing. lubricate the nose wheel shimmy damper pivots with general purpose oil MIL-L-7870.
Keep the shimmy damper clean. with a clean, lint-free cloth to prevent the collection of dust and grit.
Make sure that the part of the damper piston shaft that you can see is always clean.
Clean the machined surfaces of the shimmy damper with a clean, lint-free cloth to prevent the collection of dust and dust.
Exercise a shimmy damper before installation.
If a shimmy damper has been in storage for a long period, make sure that it moves freely before you install
CAUTION: Make sure that you do not push or pull on the shaft of the shimmy damper after it has reached its limit in either the up or the down position. If you continue to push a fully compressed, bottomed-out shaft, you can cause damage to the shimmy damper. If you continue to pull on a fully extended shaft, you can cause damage to the shimmy damper.
(2) If the shimmy damper does not move freely, push and pull the shaft through complete cycles until it does move freely. When the shimmy damper shaft has come to its limit of travel up and down as you push and pull, make sure that you do not continue to push or pull it beyond that limit of travel

VACUUM SYSTEM

By -
TTP B1-L3 ATA37 Cessna 172 B2-L2   V acuum system has a filter, vacuum gage, vacuum instruments, regulator valve, vacuum manifold,  low vacuum annunciator switches, engine-driven vacuum pumps and related plumbing.   With   Garmin G1000, the source of vacuum air is in the cabin and is pulled through the  system by the engine-driven vacuum pumps. This air goes through the gyro filter at the cabin inlet source  before it goes through the vacuum gage and gyro instruments. The vacuum is controlled by the regulator  valve. The regulator valve is on the aft side of the firewall. The vacuum air is then pulled through the  vacuum manifold and past the low vacuum annunciator switches and then into the vacuum pumps. Without Garmin G1000, vacuum pressure is measured by the low vacuum annunciator   switches in the engine compartment. The vacuum gage in the instrument panel shows the vacuum  pressure. Vacuum gag e gives a direct indication of the
