4. DISASSEMBLY, INSPECTION AND REASSEMBLY OF ENGINES [Reassemble] Apply sealant (Part No.YM 977770-01212) and install the mounting flange by matching the two dowel pins. After assembly, raise the engine with its mounting flange on the bottom side. Unforeseen injury may arise due to falling of slipping when raising or reversing the engine. Carefully operate so as not to lose balance. Point 4: Journal bearing cap [Disassemble] Before removing the journal bearing, measure the crankshaft side gap. Measure it in either method because there are the next two meth- ods.
1) Install a dial gauge on the cylinder block, and move a crankshaft in front and back, and measure the side gap as shown in the right figure. 2) Put a thickness gauge in the clearance between thrust metal and crankshaft directly, and measure it. Side gap standard mm [Reassemble] If the side gap exceeds the standard, replace the thrust metal with an oversize one. Machine the standard width of the crankshaft thrust part into the dimension of the below table at the same time. Refer to a parts book when ordering the part. The surface finishing precision (refer to 4.4.5(2) in Chapter4):
