Step 12: Inflate Tires
Inflate the tires; 2025 psi is optimum for traction, load capacity, and shock absorption. HIGHLY ADVISE
using a bicycle hand pump to inflate the tires since the air capacity is so small, or a regulated air
compressor set between 20 and 25 psi for safety and best results. DO NOT EXCEED 35 PSI as this may
cause the tube to rupture and/or break the inner rim of the HDPE version of the kit.
Step 13: Mount Assemblies to Drive Shaft
Next, mount the wheel assemblies to the drive shaft, being careful to align the drive pin to the slots cut
into the rim assemblies. Attach the wheels with (1) #¼-20 x 5/8” Button Head Screw on each assembly.
You should now have two drive assemblies that look like this:
