Tool Kit for 37000-28K.
Tool kit F-37000-TL28 includes two reamers. The reamers are used from opposite ends of the manual valve bore. The reamer marked "REAMER A" is a "self-guiding" reamer and is used alone without guide pin, reamer jig or VB-FIX. The reamer marked "REAMER B" requires use of the guide pin, reamer jig and VB-FIX to properly ream. It is critical to use the self-guiding "REAMER A" for the first reaming operation. Failure to follow this warning can render the valve body casting unusable.
