Dispute: Claim of Employes:





Findings:

The Second Division of the Adjustment Board, upon the whole record and all the evidence, finds that:

The carrier or carriers and the employe or employes involved in this dispute are respectively carrier and employe within the meaning of the Railway Labor Act as approved June 21, 1931+.

This Division of the Adjustment Board has jurisdiction over the dispute involved herein.



Adjacent to Carrier's Diesel Facility in Kansas City is a building known as the Power House, wherein are located steam generators and two stationary air compressors. On December 12, 1977, a machinist was instructed by his foreman to replace the diaphragms in one of the air compressors. Carrier's description of the work involved is not challenged by the Organization. We therefore quote from Carrier's Statement of Facts: "Replacing the diaphragms requires disconnecting 3/8" copper tubing, one end of which attaches to the unloading assembly located on the low pressure cylinder head. The tubing is attached at each end by pulling a hex nut down over a compression fitting. Disconnecting simply requires the loosening of the nut at each end of the tubing. The machinist must then loosen four nuts holding the unloader assembly to the cylinder which permits the machinist to remove and replace the diaphragm. The machinery is reassembled in the reverse order."

Further language of Carrier is criticized by the Organization only as being an over-simplification: "The claims were filed on behalf of sheet metal workers because a sheet metal worker was not used in each case to loosen the hex nuts holding the tubing in place. The loosening of the hex nuts requires no more than three or four minutes. Tightening the hex nut (sic requires four or five minutes."

We find that the disputed work is governed by the last sentence of RULE 52, MACHINISTS' CLASSIFICATION OF WORK, reading in pertinent part:

"Machinists may connect and disconnect any ... pipe connections necessary to make or repair machinery or equipment."
