|About Stihl Pistons:
The piston in a Stihl blower, chainsaw, cutter,
trimmer or other equipment is made from
aluminum. To function properly the piston must be
machined with a high level of accuracy and
precision. This is especially important for obtaining
the proper clearances between the piston and
cylinder bore. The operating temperatures within
the engine causes the piston to expand, and can
result in engine seizure if the piston is machined too
large. When replacing a worn or damaged piston in
Stihl equipment, it is important to carefully inspect
the cylinder before deciding to replace only the
piston or both the piston and cylinder.
Careful consideration should be given to replacing
a Stihl piston with the correct part number. In some
Stihl model numbers there are multiple piston sizes
and displacements available. An example is the
Stihl 034 model chainsaw which uses a 46mm
diameter piston and cylinder bore for the standard
models but uses a 48mm diameter piston and
cylinder for the 034 Super model. This 48mm
piston and cylinder is also the same as is used in
the Stihl 036 and MS360 chainsaw models.
If the piston does not include the piston rings,
careful consideration should also be given to
matching the proper size rings to the piston. In
some cases there are Stihl pistons that use rings
with a thickness of 1.2mm while another Stihl
piston with the same diameter uses rings with a
thickness of 1.5mm.
