2. Check crankcase mating surfaces with cylinder head for unevenness with the help of straight edge and feeler gauge. If necessary grind this surface just to clear unevenness. Measure across the length and breadth to specific mention value in table. 3. Ensure main bearing parent bore dimensions are within specified limits. (For specified limit and procedure refer cylinder block inspection chapter.) 4. Ensure that the minimum height of crank case is not less than the specified minimum height. 5. Tighten the hex socket counter sunk screw to join the crank sensor target wheel to crankshaft. 6. Match the lug of thrust washer with block. Insert the thrust washers from 3rd bearing from 7. cylinder block and place the upper bearing shell. (Apply the coat of engine oil.) 8. Place the crankshaft into the crankcase. NOTE Apply light coat of grease to the fourth main bearing cap. Ensure the slot on thrust washers are facing on outer side. NOTE Ensure the dowel pin. While replacing target wheel or ECU we have to do flywheel learning (for procedure refer page no 147 of petrol Engine.) NOTE Apply light coat of engine oil to all main bearing shells and crankshaft journals. Ensure crankshaft holes are properly cleaned and free from any blockages. 1.2L REVOTRON CNG PHASE-2 ENGINE 177
