Engine - Husqvarna Rider 850 Workshop Manual

Design and function

Engine

All Husqvarna Riders have engines from Briggs &
Stratton. Rider 850 and Rider 970 have single-
cylinder engines whilst Rider 1030 Bioclip and
Rider 1200 have two-cylinder engines. Both the
single and two-cylinder engines are air cooled.
More intricate engine repairs are not described in
this workshop handbook, these can instead be read
in Briggs & Stratton's own handbooks which contain
detailed information about adjusting and repairing
the engines. The handbooks can be ordered from
an authorized service workshop.
Rider 850 has a 10.5 or 12.5 hp single-cylinder side
valved engine with spray lubrication.
Rider 970 has a 15.5 hp single-cylinder, top valved
engine with spray lubrication.

It is important that only original spare parts are
used when repairing the engines. If other parts are
used, the guarantee shall no longer be valid.
Rider 1030 Bioclip and Rider 1200 have 18 hp two-
cylinder top valved engines with pressure
lubrication and a separate oil filter. These engines
can also be equipped with catalytic converters
which reduce hydrocarbon and nitrogen oxide
emissions by up to 65% and carbon monoxide
emissions by 45%.
