ABSTRACT:
An improved camshaft bushing puller comprising a split collar comprising two hemi-annular sections which can be flexibly compressed to a smaller diameter for insertion into a camshaft bushing. The outer ends of each hemi-annular section have integral outer peripheral lips adapted to engage the outer end of the bushing. Complementary threaded grooves receive the end of a conventional pulling handle which urges the bushing puller into uniform solid contact with the camshaft bushing for effective uniform pulling action.
