Adjust the position of the Extension Shaft Adjuster 
so that the Extension Shaft is running 

PARALLEL 

with the Mower Body. 

 

Note: 

It is 

CRITICAL

 that the Extension Shaft is 

PARALLEL

 to the Body when fitting the Pulleys! 

This is to ensure the correct alignment of 

BOTH 

the Rotor and Gearbox Extension Pulleys! 

 

 

 

 

IMPORTANT: 

There are 

TWO 

types of Rotor Pulley used on 

Warlord. 

 

 

 

The 

TYPE 2

 Rotor Pulley has a

 FLAT

 back 

side. 

 

 

The 

TYPE 4

 Rotor Pulley has a 

RECESSED 

back side. 

 

Inspect your Rotor pulley and determine which 
type you have. 

 

The positioning of these two types of Rotor 
Pulleys is slightly different, however the securing 
process is identical!  
See below for positioning details for each type. 

 

 

 

Flat Back - Type 2 Pulley Position

 

Align the keyway in the Taper Lock Bush with the 
Key fitted to the Rotor Stub. 

 

Slide/lightly tap the Rotor Pulley onto the Rotor 
Stub until the back of the Pulley is against the 
Rotor Bearing Locking Nut as shown opposite. 

 

Note: 

There are 

TWO 

types of Rotor Pulley used on 

Warlord, see above for detail.

 

 

 

 

Recessed Back - Type 4 Pulley Position

 

Align the keyway in the Taper Lock Bush with the 
Key fitted to the Rotor Stub. 

 

Slide/lightly tap the Rotor Pulley onto the Rotor 
Stub until the back of the Pulley is just over the 
edge of the Rotor Bearing Housing as shown 
opposite. 

 

Note: 

There are 

TWO 

types of Rotor Pulley used on 

Warlord, see above for detail.
