Crankshaft Repair
Rebuilding
The Spirit engine uses a crankshaft consisting of
many replaceable components. Individual re-
placement parts are shown in the parts manuals
and can be ordered as needed.
Because the crankshaft is one of the principal
moving parts in the engine, the crankshaft must
be handled carefully to ensure balance and
trueness. Arctic recommends that replacement of
any crankshaft parts be done only by pro-
fessional servicemen in shops equipped with the
proper tooling and equipment.
Any dealer wishing the necessary tooling for
A088
crankshaft repair can contact the Field Service
Department at Arctic for a list of suppliers.
6.
Slide the crankcase seal off the MAG end of
the crankshaft. The Pantera series crank-
shaft and seals are shown.
Remove Bearings
The Arctic bearing puller kit and additional shells
may be used to remove crankshaft bearings from
any of the Spirit snowmobile engines.
