All 1100 Series, 3100 Series, And 3208 Remanufactured Engines
Caterpillar resurfaces (machines a new surface) cylinder blocks and cylinder heads for Remanufactured Engines when it is necessary to give a better junction between the cylinder block and heads. Resurfaced cylinder blocks and heads have an identification mark on them as shown in the illustrations.
It is possible that only one deck (side) of the block will be resurfaced. If this is done, only the side that was resurfaced will have the identification mark on it.
Caterpillar will not assemble engines with a resurfaced cylinder block deck and a resurfaced cylinder head on the same side. This will make it possible to resurface the components again if the engine is rebuilt again in the future.
Illustrations 1 and 3 show where to measure the cylinder blocks and heads. The chart that follows gives the original and the minimum permissible resurfaced dimensions.
It is possible to use a resurfaced cylinder head on a resurfaced cylinder block deck, but dimension A plus dimension B must be a minimum 418.39 mm (16.472") to prevent valve to piston contact.
Illustration 1. Location of dimension A and the identification mark on the cylinder block.
Illustration 2. Location of View B-B and the identification mark on the cylinder head.
Illustration 3. Location of dimension B.
