Requirements: check out whether the 
brake drum is cracking or over-worn 
 
2.3 Installation the brake drum 
Clean the wheel hub surface connected to 
the brake drum and then tighten it with 
cross recessed countersunk head screw 
after it alignment with Bolt hole and cross 
recessed countersunk head screw. 
 
2.4Measurement drum-shoe clearance and 
Drum-shoe clearance difference 
1） Using a wrench adjust the whole arm 
worm six Angle head clockwise until the 
brake drum contacts with brake drum and 
then rotates it counterclockwise. (270) 
 
2）Open the sealing plug, measure 
drum-shoe clearance with filler gauge。 
Requirements :drum-shoe clearance:
（0.7-1.2）mm 
drum-shoe clearance difference≤0.30mm 
 
3）If the drum-shoe clearance does not 
meet the requirements, you need to rotate 
worm six Angle head of adjusting arm 
with wrench to meet the requirements 
and then slack adjusters worm hex head 
clearance adjustment to regulation and 
then after put the sealing plug in place.
