New Debris Shield Is Added To Cylinder Head Gasket Kits{1124}

Usage:


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

Description of Change: The new debris shield is now included with the top end gasket kits listed below. The debris shield is made out of triple-walled cardboard with a plasticized coating to resist water and oil. This debris shield is designed to fit over the liner flange to seal the cylinder block deck water, oil and drain passages from flying debris which is generated when cleaning the combustion chamber. The debris shield is held in place by three dowels that locate the cylinder head. There is a punch out piece that can be inserted into the cylinder bore after cleaning to protect it until re-assembly.

Adaptable To: A new 133-1774 Debris Shield is now included in the following new gasket kits:

* 137-1933 Gasket Kit for magneto ignition engines
* 137-1934 Gasket Kit for electronic ignition systems with water cooled exhaust manifold
* 137-1935 Gasket Kit for electronic ignition with dry exhaust manifold

The new gaskets kits are effective with the G3508 (4WD, 2JF, 9TG), G3512 (4KC, 5JD, 7NJ), G3516 (3RC, 8LD, 4EK, 5PN) Gas Engines. The 137-1933 Gasket Kit cancels and replaces the 105-1865 and 105-2550 Gasket Kits. The 137-1934 Gasket Kit cancels and replaces the 116-6744 Gasket Kit. The 137-1935 Gasket Kit cancels and replaces the 135-8814 Gasket Kit.
