Crank Shaft Double Groove Pulley

This is a new heavy built and high quality double grove crank pulley. This is for the CJ2A, CJ3A, and CJ3B.  This has one large grove and one small grove.  The large grove is for the standard large belt for the water pump and generator and the small grove is for the governor system.  These can be used just like a regular single groove pulley on your 134L and 134F motors but you will just have an extra groove.  

NOTE: If you have the extra flange on the front of your timing cover this may not fit. Inside measurement of depression is 3 7/8″.
