One of the most critical aspects of snowmobile mainte-
nance is off-season storage. Proper storage prevents en-
gine and suspension damage and fuel system
contamination. Improper storage causes deterioration and
damage.
Preparation for Storage
Careful preparation will minimize deterioration and
make it easier to restore the snowmobile to service later.
When performing the following procedure, make a list of
replacement or damaged parts in order to order and install
them before next season.
1. Remove the seat and clean the area underneath the seat
thoroughly. Wipe the seat off with a damp cloth and wipe
a preservative over the seat to keep it from drying out. If
concerned about the seat during storage, store it away
from the snowmobile in a safe place.
2. Flush the cooling system as described in Chapter
Three. Before refilling the cooling system, check all the
hoses for cracks or deterioration. Replace hoses as de-
scribed in Chapter Eight. Make sure all hose clamps are
tight. Replace questionable hose clamps as required.
3. Change the chaincase oil as described in Chapter
Three.

electrical contact pins for damage or looseness. Repair
connectors as required. After the contact cleaner evapo-
rates, apply a dielectric grease to one connector half and
reconnect the connectors.

Dielectric grease is formulated for electri-
cal use. Do not use a regular type grease on
electrical connectors.
