®

 II assembly. 

 

 Remove both shackles from one ARCOUPL bar. 

 

 Align the holes of the ARCOUPL bar with the BUMP3. 

 

 Secure both ends of the BUMP3/ ARCOUPL assembly. 

 

a.

 

Drive a pierced bolt into the holes at one of the bar end 

 

b.

 

Drive the pierced nut 

 

c.

 

Secure with a cotter pin.
