Center Wheel Assembly Instructions (QTY 2) 

Step 1:

 Place a 6mm D-Bore Double Boss Nub 

(am-3215a) into the center bore of a 4" 8mm 
Bore Wheel on the flat side of the wheel.  

 

 

Step 2:

 Flip the wheel over and secure the 

Nub to the wheel by threading two 6-32 x 
1.25 in Hex Head Screws (am-1437) into 
the Nub. Be sure to place the 6-32 screws 
in opposite holes of the wheels.  

 

Step 3:

 Place a 24 Tooth HTD Pulley Extender 

(am-3404) between two 24 Tooth HTD Pulley 
Halves (am-3401_half), and place all three 
components onto the boss of the Nub. 

 

2X 

Step 4: 

Align the bolt circles of the Nub and the 

Pulley Assembly, and secure the pulley by 
threading two 6-32 x 1.25 in Hex Head Screws 
(am-1437) into the Nub. Be sure to thread the 
screws into the opposite holes that were used to 
secure the Nub to the Wheel.  

 

Repeat one more time to make 2 total Center Wheel Assemblies. 

 

 

NOTE: This subassembly applies to any 6WD TileRunner 
configuration utilizing a Stealth, Performance, or 
Compliant Wheel as the center wheel. See Page 20 for 
Performance Wheel Assembly Instructions.
