Back in '05, I disassembled and then re-assembled my Bass/Tohatsu M50D2 engine.
This is a partial photo journal of that procedure.
I disassembled my engine to have the
crankshaft pins welded in place.
This procedure, although not required,
is recommended by Bass Machines
to increase the engine's durability
under race conditions.
Below you can see the engine block.
First, the complete block.
Then, with the reed blocks removed.
Last, with the crankcase cover removed.
