BLADE REPLACEMENT
i.
Removing The Shaft
First remove belt cover from engine, then loosen (4) mounting bolts on
base of engine. Tension on drive belt is removed by moving engine
forward on deck. Remove V-belt. The pulley on the blade shaft is a taper
lock type. Remove the (3) screws from the outer pulley’s blind holes and
thread them into the tapped holes. Tighten these screws evenly ¼ turn at
a time, until the outer pulley comes away from the inner piece. Remove
the (2) bolts holding each bearing and the shaft can be removed from the
deck.
ii.
Removing The Blades
Spiral Blade Pattern (BLT-15)
The bearings are an eccentric locking type.
Loosen the set screw first, then use a punch
in the hole of the collar to twist it to unlock.
If the collar does not move in the first few
hits, try going to the way. Once the bearing
is removed, loosen the (2) lock nuts at the
end of the shaft, and remove the shaft
collar.
The blades and spaces will slide easily off of
the shaft. When re-installing the blades,
place each successive blade 1/8 of a turn
(one notch) in the same direction to
produce
a spiral effect. The BLT-14 & BLT-15 use (2)
spacers between each blade, the BGT-27
model uses (1) spacer between each blade.
Re-install the collar and nuts, and reverse
procedure.
