Tool Assembly and Operation
- Select the proper expanding driver and washer from the expanding
driver and washer information.
Important: To install or remove the expanding driver, always push on or pull from
the ends.
Pressure on the outside diameter may cause a bind against the rubber
expanding sleeve.
- Place the expanding driver onto the expander assembly.
- Check to insure that the separation lines between the segments
of the expanding driver align with the separation lines of the expander assembly.
- Place the guide cone over the driving bar (with the small end
of the cone facing the driver assembly).
- Place the driving washer over the threaded portion of the expander
assembly.
- Screw the expander assembly (with driving washer) onto the driving
bar.
It may be necessary to install the driver bar extension for removal
of the inner bearings.
- Insert the tool into a
inner camshaft bearing and tighten until snug.
Operate the tool from the front or rear of the engine block.
On some engine blocks the nut on the expander assembly is inaccessible
except from either end. In this case you must use a socket and extension to
enlarge and reduce the expander assembly.
- Slide the nylon cone into the front or rear camshaft bearing (this
will properly align the tool).
- Drive the bearing out of or into the engine block.
- Repeat the procedure for the additional inner bearings.
- For the two end bearings
(front and rear), remove the nylon cone and driver bar extension.
- Drive the bearings out of or into the engine block.
