ALTERNATOR GP-CHARGING 1005047 - Caterpillar

All 1100, 3100, 3208NA and 3208T EnginesAn installation procedure for the cylinder block kit is shown in this instruction. There may be enough parts in the service kit to make it adaptable to more than one engine application. This means that there may be more parts in the kit than are needed for a single engine arrangement. Put identification on any parts not needed and either put them back in stock, or discard them. After the engine has been rebuilt using either the new short block group or the new cylinder block service group and the necessary parts from the old engine, be sure to do the pressure lubrication procedure before the initial (first) start-up of the engine. See Form SMHS7701 for the pressure lubrication procedure.Installation Of Short Block Group Or Cylinder Block Service Group For 1100, 3100 and 3208 Naturally Aspirated Engines
In those applications where the original crankshaft is to be used again with a new cylinder block service group, check the crankshaft carefully to find the location of the oil supply passage for the No. 1 connecting rod bearing. (1) If the crankshaft has an oil passage (A) from the No. 1 (front) main bearing journal (1) to the No. 1 connecting rod bearing, it will be necessary to install a No. 1 main bearing with an upper half (2) that has a lubrication groove (B). (2) If the crankshaft has an oil passage (C) from No. 2 main bearing journal (3) to the No. 1 connecting rod bearing, it will be necessary to install a No. 1 main bearing that has an upper half similar to upper half (4), with no oil groove. (3) Install the correct upper half of the No. 1 (front) main bearing in the cylinder block. Locating tab (D) of the upper half of the No. 1 (front) main bearing, must fit in tab slot (5), in the center of the bore. Tab slots 6, 7, 8 and 9, for main bearings 2, 3, 4 and 5 are to the right of center as shown in the illustration. Install main bearings 2, 3, 4 and 5 in their correct location. Tighten the main bearing caps according to the Specifications in the Service Manual.Installation Of 5B1866 Plug And 9M575 Dowel On 1100, 3100 And 3208 Naturally Aspirated Engines
Sleeve Metering Fuel System
Compact (Scroll Type) Fuel System
Before installation of a short block group or the cylinder block service group, see the illustrations above to determine which type of fuel system is on the original engine. If the engine has a compact (scroll type) fuel system, do not install the dowel and plug. Lubrication to and from fuel injection pump and governor will be stopped.
(1) If the engine has a sleeve metering fuel system, install 9M575 Dowel (1) and 5B1866 Plug (2) to the dimension shown.(2) If the engine has a compact (scroll type) fuel system, do not install dowel (1) or plug (2).Installation Of Short Block Group Or Cylinder Block Service Group For 3208
