All G3600Engine News SEBD9844, 06 February 2013, "Proper Installation of Connecting Rod Bearings for G3600, 3600, and C280 Engines". Disregard the previous article. Refer to the information below.The 227-2902 Bearing is harder than the previous bearing, therefore additional caution must be taken during the assembly process to ensure cleanliness. The assembly steps listed here will help prevent contamination of the bearing surface.Note: For G3600 low compression engines, the 227-2902 Bearing is relatively new. For these engines, the 227-2902 Bearing is a direct replacement for the 192-7870 Connecting Rod Bearing. The change is effective at the factory with the engine serial numbers that are listed in Table 1.

Handle parts and store parts properly.
Inspect all parts for contaminants and defects.
Keep all parts free of contaminants.Refer to Table 2 in order to select the correct bearing.

Only install the bearing in a clean environment. Avoid open doors or fans that might allow dust to be blown into the crankshaft and rod bearing area. If the engine is not in a building, a temporary wall may be necessary in order to control the environment.
If the crankshaft has been turned or polished, the oil passage plugs must be removed. Clean the threaded holes and oil passages thoroughly with a brush and solvent. A new 7W-1632 Plug must then be installed and staked. Apply Loctite Dri- Loc 200 to all of the male threads and all around the circumference of the threads.Torque for the plug ... 300 40 N m (220 30 lb ft)
Rotate the crankshaft in order to position the piston being removed at TDC. Install the 145-5190 Piston Support or the 156-7160 Piston Support As in place of the piston cooling jet.
During the removal process, remove the connecting rod cap. Remove the connecting rod bolts.
Rotate the crankshaft journal away from the connecting rod in order to provide clearance for cleaning the connecting rod bore. When the journal is clear of the connecting rod, cover the journal with a clean cloth and tape the cloth to the journal. This precaution will prevent debris from landing on the journal or from entering an oil passage.
