OPERATIONAL FEATURES
6 TON PROTO-EASE™ CONE PULLERS
Forcing Screws should be easy to turn—
and most are—when the load is fairly light.
But tough pulling jobs are a different story.
Most screws tighten up when the going gets rough,
resulting in far less output than you apply. Why? Because
there’s frictional resistance. The thread and threaded hole
are fighting each other all the way. Not with Proto! We’ve
got Acme threads to increase your muscle power. Acme is
the thread with a long-lasting reputation for easy turning and
smooth-as-silk performance. Reversible 3-Jaw Puller Used to
remove the drive and head and
bearing of an alternator.
Since the Adjusting Cone
threads on the Crossblock and
not onto the Forcing Screw, it is
isolated from the torque of the Screw.

NOTE: ALL PROTO-EASE™ forcing screws are coated at the factory with the latest aero
space dry film lubricant to increase screw life, reduce wear and torque required for
screw turning. It is recommended that a few drops of medium grade oil (SAE 30 or equiva
lent) be added to screw threads prior to every use. Screw threads must be kept clean at
all times.
