O-RING 0983204 - Caterpillar

1 Look at location (A) of the former cylinder block. Some engines have a 1S1768 Sleeve (1) and 4L3395 Dowel (2) at location (A), and other engines will have a 4B3938 Plug (3) and 2A3798 Dowels (4). Install the correct parts at location (A) of the new cylinder block, so it will be exactly the same as the former cylinder block.2 When the spacer plate gasket, spacer plate and head gasket are installed, they are to be clean and dry. Do not use sealant. Be sure to install the 7N8018 Seals and 4W8087 Seals before installation of the cylinder head. Install all other needed parts from the former cylinder block, on the new cylinder block. See the information that follows for installation procedures. See the Service Manual for specifications.Installation Of Fuel System (Early Counterbore Engines That Have Scroll Type Fuel System)
1 When the scroll type fuel system from an early model 3306 Engine (with cylinder liner counterbores) is to be installed on a Remanufactured Short Block Group, it will be necessary to use a 2P8704 Fuel Pump Bracket to fasten the fuel pump and governor to the side of the cylinder block on those short block groups that do not have cylinder liner counterbores (a spacer plate block). The bracket that was used with the former cylinder block (block with cylinder liner counterbore) cannot be used on a Remanufactured Short Block Group that does not have cylinder liner counterbores. At installation of the fuel pump bracket, always use new seals and gaskets.Earlier Engines That Are Equipped With An Air Compressor
1 For those earlier engines that are equipped with an air compressor, it will be necessary to drill and tap a hole at boss (A) for installation of an oil drain line for the air compressor. Make the threads in the new hole the same size as those for the old cylinder block.9L5797 Oil Pan Group (Front Sump)
1 For those 3306 Engines that have a 9L5797 Oil Pan Group, use three T65 Bolts (1) at
