Remove 4 bolts attaching spindle assembly to mower frame and remove as a unit,
since pulley will come out through the hole in the deck.
SPINDLE ASSEMBLY INSTALLATION:
Reverse above procedure. Be sure spindle mounting area of deck is clean of any
foreign material before attaching spindle assembly.
SPINDLE REPAIR:
Spindle repair requires special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in this type of repair, you may
be time and money ahead to use a new spindle assembly.
Remove pulley from spindle assembly. Place assembly in press and force spindle
down through housing. Once pressed apart, replace bearings, as removal will have
damaged bearings internally.
