!
Set rear end of Main Root Tube between center supports on Back Frame.
2.
!
Insert Delrin spacer into rear of Main Root Tube.
3.
!
Align bolt holes in Root Tube to holes in Main Root Tube.
Insert both AN5-36A bolts through holes, using a AN970-5 washer at head of bolt, and
two AN960-516 washers at bottom of bolt, and secure with a AN365-524A Nylock Nut.
By using 2 washers at bottom of each bolt, you can ensure that when you tighten the bolt
securely, you will minimize the chance of over-tightening the bolt and compromising the
threads and bolt shank.
