The following pictures document my success at extracting my "reluctant" 48 yr. old clutch pilot bushing from its housing. Thank you, Bigdog for all your encouragement.
My tools, clear & simple: 3/4" X 10 tap, 3/4" X 4" bolt (3/4" X 6" bolt w/ 3" of thread would have been a better choice and eliminated the need for a socket used as a spacer.), 12" tap wrench.
The careful chasing of threads in the worn bushing begins. Notice my arched block & wedges to immobilize the fly wheel.
Threads have been chased & thoroughly cleaned (I removed tap several times for more complete chip removal; WD-40 for lubricant)
Bolt threaded in w/ 1/2" drive ratchet and 1 1/8" socket; bolt end bottoms out; bushing begins its forward movement.
Forward progress visible; almost effortless extraction.
More than half way of its 1" of travel.
Almost effortless extraction; absolutely no damage anywhere. Notice 1/4" socket in hole, used as spacer for more thread travel. This would have been unnecessary if a 3/4" X 6" bolt w/ 3" of thread and been available.
Perfect side wall clearance.
