82E-5 – 98E-5 SERIES 4-35
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):
0.25mm Oversized thrust metal (0.25DS) mm
The standard width of the crankshaft thrust part mm
