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.
