4. Use a 10# sleeve to remove the fixing bolt of
crankshaft lower bearing cap and cylinder block.
5. Use a 19# sleeve to remove the fixing bolt of
crankshaft main bearing cap.
Note:
The surface between cylinder block and bearing cap
is ensured by high precision machining plane, so, do not
use any hard article to scuff this surface.
6. Take off crankshaft rear oil seal assembly, remove
bearing shell cover, and then take off crankshaft
assembly.
II. Overhaul of Crank-Connecting Rod System
1. Detection of crankshaft.
1.1 Detection of crankshaft main journal: use an
outside micrometer to measure main journal of
crankshaft and the normal value should be
46.01mm.
1.2 Detection of connecting rod journal: use an
outside micrometer to measure connecting rod
journal of crankshaft and the normal value should
be 44.485-44.495mm.
