Tap the key into the wheel hubs, centralize axle, & tighten 
the hub clamping soc cap.  

(N.B. The key should not be too tight that it is unable to be 
tapped into position & also should not be too loose that it is 
a sloppy fit. If the key is too tight it may be lightly dressed 
with a file, if it is too loose it can be centre punched from the 
top & if necessary dressed back with a file to produce a tap 
fit.). 

 
On either end of the axle place the external contracting 

30mm circlips 

in the grooves provided. 

 
When you are happy that the axle is centralized, small 
 indents aprox 2mm to 3mm should be drilled in the axle 
through the bearing grub screw holes & the grub screws  
refitted  
 
N.B. Take care not to damage the threads when drilling or lose 
the grub screws. 

(Remove any swarf). 

These, once fitted, will 

prevent the axle moving sideways under heavy side loads. If a 
small recess is not made & the screws are fitted, the surface of 
the axle will be damaged making it difficult to remove the 
bearings.  
 
Mount the rear wheels to the hubs with the tapered end of the 
nuts against the wheel & the valves facing outwards. 

 
 
Insert the 

6mm key 

into the 

sprocket carrier, adjusting the 
fit as before. It is good practice 
to clamp to the axle firmly 
first then tighten , the six 
sprocket fixings.  
 

 
 
The whole assembly may now be un-clamped, the alignment 
adjusted , the key checked & then re-clamped. 
 
 

 
 
Insert the 6mm key into the brake 
carrier, adjusting the fit as before, 
& clamp the disc centrally. It is 
good practice to clamp the carrier 
to the axle firmly first, then tight-
en the six disc fixings. 
 
 

 
 
The whole disc assembly may now be un-clamped, the 
alignment adjusted, the key checked & then re-clamped. 

Mount the brake calliper over the disc,  

2x M8 x 20 soc cap & 2x M8 washers.  

Run hydraulic tube around the recoil 
side of the engine, secure the tube away 
from the engine with tie wraps.  

 

Mount the master cylinder to the  
inboard side of the bracket behind the 
seat. The hydraulic tube underneath 
facing the rear, actuating arm pointing 
up to the rear. 

2x M8 x 20 soc caps.  

2 x M8 washers. 

Fit the brake rod with 

1 x M6 lock nut 

either end followed by 

clevis, pins & clips. Secure assembly to the pedal &  brake 
cylinder arm. 

Please refer now to the following mechanical brake fitting 

instructions.
