Functions

The tool is designed to pull items 

such as bearings, pulleys,  and chucks 

from shafts. The Jaws (1) grip the item 

from the inside or outside, whichever of-

fers a better grip. The Piston (8) will push 

on the central shaft while the Jaws pull 

away. This will remove the item from the 

shaft by pulling it straight out evenly, with-

out hammering or binding from pulling at 

an angle.
