Passo 1

Before you begin, ensure the machine is powered down and cool to the touch.
Turn the ignition switch to the off position.

Passo 2

Flip the fuel cutoff valve switch into the off position.

Passo 3

Grab the plastic housing at the end of the spark plug wire.
Pull firmly to disconnect the wire from the spark plug.

Passo 4

Tilt the machine so that it is resting on the handle with the cutter wheel raised.

Passo 5

Use a 14 mm socket to remove the fasteners securing the belt guard:
One 10 mm bolt
One 10 mm nut

these are 10mm fasteners, not 14mm , measure the distance from the outer thread on one side to the outer thread on the other side, this is called : major diameter

Passo 7

Use a 9/16 inch socket to loosen the four nuts securing the bottom of the motor enough to allow the motor to slide freely. Do not remove the nuts.
Use a 1/2 inch wrench in combination with the socket wrench to hold the bolts in place.

Passo 8

Use a 1/2 inch wrench to loosen the two bolts behind the centrifugal clutch enough to allow the motor to slide freely. Do not remove the bolts.

Passo 9

Wrap a piece of tape around the upper half of the tensioner bolt to mark the location of the second nut.
Use a 9/16 inch wrench to loosen the nut on the lower half of the tensioner bolt until the motor can slide forward as much as possible.
During reassembly, reference the tape to position the outer nut into the same location as before to ensure proper belt tension.

Passo 10

Slide the engine towards the cutter blade to loosen the drive belt.

Passo 11

Lift the drive belt up and away from the machine while rolling it towards the cutter head to gradually roll it off of the pulley.

Passo 13

Use a 1/8 inch hex key to remove the pulley set screw.

The set screw secures the bushing, which secures the pully.

Passo 14

Use a universal puller to remove the pulley from the cutter wheel shaft:
Attach the universal puller to the pulley using the three bolts provided on the pulley.
Use a wrench to torque down the center screw to slowly loosen the pulley.
This may take a lot of force.
If the pulley seems to be stuck after significant pressure is applied with the universal puller, use a blowtorch to apply heat where the pulley contacts the shaft.

The bushing attached to the pully has 6 holes.

Three are used to attach the bushing to the pully when the machine is operational.

The other three are used during disassembly to pull the bushing from the pully using the universal puller.

Once the bushing is pulled away from the pully, everything slides out easy.

If you try to pull the bushing while it is attached to the pully you will be pulling the pully and the bushing at the same time, everything will compress on the axel and make removal of the bushing and pully more difficult.

The universal puller removes the pulley. What is the tool to put it back on?
