Part of Lesson Plan: **Remove and Replace a Valve (updated) by Steve Nagle

Activity Overview / Details

In order to remove the two tapered valve locks the spring must be compressed.  On the manual valve spring compressors move the handle upwards (towards the fingers).  On pneumatic valve spring compressors locate the depress and release buttons.  Activate the buttons before trying to remove the valve spring to see how far the piston extends.
