Engine News SEBD9887, 8 August 2013, "A New Cylinder Head Gasket and Spacer Plate Are Used for Certain 3500 Locomotive Engines". The article was revised to add part numbers to Table 4 and 5.Description of Change: A new multi-layered steel cylinder head gasket and a new spacer plate are used.The new cylinder head gasket can be used with the new spacer plate and with the old spacer plate.The old cylinder head gasket can be used with the new spacer plate and with the old spacer plate.The new spacer plate requires a new specification for cylinder liner projection.The new cylinder head gasket requires a new torque procedure for the cylinder head bolts.Adaptable To: The part numbers of the new cylinder head gasket and spacer plate are listed in Illustration 1 and Table 1. The old part numbers are not canceled.

S/N:T2X00123 Measuring Wear of the Cylinder Block at the Cylinder Liner Contact Surface
Illustration 2 g02657157
Points at which to measure the depth of the wear around the circumference of the cylinder bore
Illustration 3 g02658239
Using tool (A) to measure the depth of the wear in the cylinder block under the cylinder liner flangeUse tool (A) to measure the depth of the wear in the cylinder block in the area under the cylinder liner flange. Take measurements at the eight points that are identified in Illustration 2. Illustration 3 demonstrates proper placement of the dial indicator between the tapped hole and the cylinder bore.If the depth of the wear under the cylinder liner flange is greater than 0.013 mm (0.0005 inch), the block must be salvaged according to Reuse And Salvage Guidelines, SEBF8255, "Procedure to Salvage Top Decks of Cylinder Blocks of 3500 Engines".Calculating Cylinder Liner Projection
The following method for calculating the liner projection is the preferred method under these circumstances:
Single cylinder head joint repair
Engine rebuildThis procedure also enables use of the 110-6994 Spacer Plate with the new 362-8264 Cylinder Head Gasket .Note: When installation of spare
