FYI: I've been wondering about the rear idler system and wanted you to see it and maybe help me figure out the reason for how it's designed. I'm just curious and somebody may know.
The two rear idler wheels each have pretty beefy idler arms independent of each other. There's a slide adjuster on each one that can be set where ya want it, up to down. THEN the idler itself has it's own brass idler angle adjuster.
One pic shows the frame swingarm down and the other side shows it up. Down is almost level with the roadwheels on the ground and the other is up high like an idler. And you can see the heavy swingarms and the slide adjusters on each side.
When I took this apart the swingarms, adjusters, nuts, shafts, were 'frozen' in place cause they didn't have any grease on'em. I took'em apart, cleaned, and greased'em and now they all move free.
It's just a wonderment to me WHY it has swingarms to adjust up/down AND idlers for back and forth track adjustment. Was it for extra ground pressure over soft ground? Do anybody know? Just curious.
