1. Attach Root Tube Angle Plate (HT463) to Front Root Tube (HT431A) and Main Root Tube 
with 6 bolts (AN4-27A).  Use AN960-416L Thin Washers on both sides, and secure with 
MS21083N4 Thin Nylock Nuts. 
 
2. Insert Root Tube Bearings into top holes.  Use a rubber mallet to gently pound bearings into 
holes.  Note how the picture shows a 

¾

” socket placed over bearings to aid the compression of 

bearing into hole as you pound it in.  There are two holes with bearings, so you can choose 
which hole to use.  A taller pilot would prefer to mount the front fork in the hole near the front 
of trike, and a shorter pilot may elect to use the rear hole, for a comfortable distance from seat 
to fork pedals for steering, braking, and foot throttle.
