buttons by drilling a 0.18" hole in the center of a button
on one side of the spider.
2. Place a pin punch through the drilled hole in the button
an
d drive the opposing button and pin out.

t
he trailing (right) side of the spider leg as viewed from

Roller Installation
NOTE: Use care to start the pin straight. Aluminum
burrs could pass through into the roller bushing
causing it to bind and stick. Also use care to make
sure the roller remains aligned when the pin is driven
through. The roller busing could be damaged causing
premature wear and roller failure.
1. Drive pin into the spider leg .100" -.125" (0.25 -
0.3
2cm) beyond the first land of the spider leg.

pr
otruding from the spider leg.
3. Place roller in spider leg and center it on the pin.
