Introduction Of New Spark Ignited Single-Cylinder Gasket Kits {7555}

Usage:

G3508 (4WD, 2JF, 9TG),
G3512 (4KC, 5JD, 7NJ),
G3516 (3RC, 8LD, 4EK, 5PN) Industrial Engines

Description of Change: Three new gasket kits have been released that are specifically designed for three general engine applications:

* Engines equipped with a magneto

* Engines equipped with an Electronic Ignition System (EIS): Dry manifold or wet manifold

The new gasket kits include the new integral seal and cover.

The new integral seal replaces the former integral gasket.

The new cover may be installed around the cylinder liner. This keeps debris from falling into the crankcase while cleaning the ash deposits from the piston crown and off the walls of the liner above the turn-around line.

Adaptable To: See the chart for adaptability of the new gasket kits.

The new gasket kits are serviceable and designed to be used as a single cylinder repair kit.
