Locations of the filled-in ends on the new 7E6000 Gasket and on the temporary parts service 7E3240 Gasket. The added material shown at both ends also makes it possible to identify from the outside of the engine the new 7E6000 Gaskets from the former 2W7983 or 9Y7786 Gaskets. (A parts service only 7E3240 Gasket also had both ends filled in.)... This gasket is NOT coated on the cylinder head side. It DOES have a single layer of black Teflon® (PTFE) on the spacer plate side. The PTFE prevents sticking to the aluminum spacer plate. Adaptable To: The gasket is effective with the following engine serial numbers. 3406B Vehicular Engine: 70V311543406B Truck Engine: 4MG622773406 Truck Engine: 92U664433406B (PEEC) Truck Engine: 8TC85193406 Spark-Ignited Engine: 4FD1753406 Industrial Engine: 90U198093406B Industrial Engine: 6TB59503406B Generator Set Engine: 2WB72523406B Marine Engine: 4TB22163406B Generator Set Engine (Standby): 4RG446This new 7E6000 Gasket can be installed in place of the former 2W7983, 9Y7786, or 7E3240 Gaskets which are all canceled. For your information, a summary of their use on truck engines only and the features of these four gaskets are in the chart.
Any time the new head gasket is to be installed, refer to the following topics so that maximum life can be obtained from the new gasket, head, block, spacer plate, and engine block.
Liner Projection And Machining The Block And/Or Head
Do NOT adjust the liner projection above the block if it measures in the range of 0.03 to 0.15 mm (.001 to .006"). ALSO, make sure that the differences between all four measurements at any one cylinder do not exceed 0.05 mm (.002"). AND, the difference between the average projection of two liners next to each other must not exceed 0.05 mm (.002"). These specifications are in the Service Manuals for these engines.
Wear or erosion under the liner flange will require use of a stainless steel insert. Read the reference article about the new liner seat insert. The head and/or block surfaces may have been damaged if the engine was operated extensively after a head gasket failure.
To prevent entry of debris into the engine when cleaning excess Teflon from the block and head, use a clean Scotchbrite® pad only. Read the second reference article which gives additional guidelines on cleaning, inspection, and repair considerations. Be careful with a rotary pad to be sure the flatness of the block and/or head is not changed.
The maximum amount of material that can be machined from the top deck of the block is controlled by the minimum dimension from the crankshaft centerline to the top deck on the block. This minimum is 425.02 mm (16.733"), and is also in the Service Manuals. Use the 6V7840 Deck Checking Tool Group to measure this dimension. Special Instruction SEHS8187 explains the use of this device.
There is also a minimum allowable thickness for the head. This is 111.51 mm (4.390"), and limits the amount of material that can be taken off the bottom of the head.
