About Stihl Cylinder Kits:
Cylinder kits are often required when Stihl equipment is
diagnosed to have a damaged cylinder bore. Most kits
contain the cylinder, piston, piston rings, piston pin and pin
retainer clips. The cylinder base gasket, exhaust gasket,
cylinder bolts and piston needle bearing are usually not
included and must be purchased separately.
In some situations a full cylinder kit is not required and the
engine fault can be corrected by replacing the piston rings,
piston, cylinder only, cylinder base gasket or a combination
of any of these.
Stihl cylinders are made from cast magnesium that have
been machined to close tolerances with a chrome plated
cylinder bore for wear resistance. Stihl pistons are made
from closely machined aluminum.
Most Stihl cylinders are fastened in place using Torx
number 27 (T-27) head bolts, and a long shaft #27 Torx
wrench is required to reach these bolts through the cylinder
access holes.
