Until recent years Vulcan Pile Extractors utilized a Steel Spring and Spring Guide in the Cylinder head as shown below:
To convert older Extractors to the new configuration which replaces the Spring and Spring Guide with a Rubber Bumper the procedure is as follows:
- Drill through at “A” 1 1/2″ diameter.
- Remove Spring Guide and discard.
- Tap hole for 1 1/4″ NPT.
- Insert countersunk Pipe Plug 1 1/4″ size.
- Install Bumper as shown.
