3.4 Long Fishing Neck Configuration
The Tool Catcher can be configured for long fishing necks by removing the
upper finger set. Follow this procedure to re-configure the assembly for this
purpose
Split the top and bottom sub connection and remove the top sub
Remove the spacer spring, finger assembly and shock absorber from
the top sub
Fit the spacer ring at the bottom of the top sub bore then the spacer
spring
Ensure that the finger seal sub is still fully made up to the bottom sub
as this connection may have backed off when removing the top sub
Verify that the ‘O’ ring is still in good condition – replace if required
Make up the top sub again taking care not to dislodge the parts inside it
Feel from the top end that the parts inside are held together correctly
Open and close the fingers to ensure that they are operating correctly
Note – When ever the top sub is removed check
that the seal sub has not backed off before re-
assembling.
