If these are replacing rubber bushings I don't see the need to heat

replacement, like the off-roaders 4 wheelers use.

These bushing assemblies attach the front of the swingarm (rear
fork , to some) to the pivot shaft . This shaft attaches to the
frame , and also supports the rear of the engine/transmission
assembly . This is an 800 pound touring motorcycle ... and those
composite bushing assemblies are quite a bit more complicated than a
"rubber bushing" .

What you're making is similar to these, no? http://tinyurl.com/2el9xx
Those are delrin with high carbon steel sleeves. I didn't ask if
they're heat treated, but I suspect so.

Actually, I just pinged Kevin there and will letcha know.

Actually , the ones I've made are as close to the OEM cleve block
dimensions as I can get (a kind soul sent me some cad files ...wanna copy ?)
.. All the other small parts will still be used , including the compliance
ring on the outside of the unit .
I looked at the sta-bo and another , couldn't see from the pics where they
allow rotation between the swingarm and the pivot bolt . The inner sleeve on
these will be held captive between the tranny case and the outer rubber
mounts , just as original . The outer shell will rotate with the swing arm .
I haven't decided yet how I'm going to establish end play , I can either
press precisely , or set tthe outer to a preset depth and shim the thrust
faces .
I got all the stuff together to heat these , and still can't decide if
they really need it .
