Semi-finished gas pistons without recesses
Motorservice offers semi-finished
pistons without recesses for the special
requirements of gas engines for which
there is no standard piston. The crowns
of these pistons can be freely formed and
can therefore be machined to match your
precise requirements.

Scope of supply
The pistons are supplied including an
enclosed piston ring set, piston pin and
circlips.

Order information
To order the gas pistons, please get in
touch with your contact person from our
Sales team.

If required, we can machine the gas

pistons in our Competence Centre in
Asperg according to your requirements and
specifications, and based on drawings or
templates.
Our Sales team will be happy to provide
you with a quotation for this machining
work.

You can obtain corresponding cylinder

liners from Motorservice.
