BBC / BOS / BCS
Under Deck Components Disassembly
(Toro Vacu Power/Lawn-Boy Medallion)
5. If further disassembly is required, begin by removing
the crankshaft nut. An impact wrench works best.
However, if you must remove it manually, use a large
screwdriver or bar to wedge the BBC flywheel while
removing the nut (Fig. 170).
1.
Stop the engine and disconnect the spark plug lead
to prevent accidental starting. Drain fuel.
Note: Be careful not to damage the bearing seal
when removing this nut, or premature bearing
failure could result.
2.
Remove the 2 flanged nylon locknuts securing the
blade to the bearing block and remove the anti-scalp
cup, the blade, the blade spacer, and the lower BBC
screen (Fig. 169).

6.
Pivot the brake plate counterclockwise slightly and
remove the bearing block and brake drum from the
crankshaft (Fig. 171).
3.
4.
Remove the 4 flanged head self-tapping screws
securing the lower BBC cover to the housing, and
remove the lower BBC cover.
Before disassembling further, check to make sure
that the BBC components are functioning normally.
Make sure that the brake and brake drum fully
disengage when the control bar is cocked, then
raised. Make sure that the BBC flywheel and the
brake drum rotate together when the control bar
is raised. Make sure that the belt loosens properly
when the control bar is lowered. Repair or replace
parts as required.
