It is important to keep your Vulcan hammer properly lubricated to insure the maximum possible hammer life and driving performance.

Also, for the threads of the cable fittings. use an an anti-seize compound to prevent galIing and freezing of the threads.

*NLGI EP2 greases will vary widely in the results for this application. Another alternative to this is a heavy open gear lubricant with MoS2 anti-wear additive. This should be applied directly to the exposed columns.

Lubrication Diagram

Right: an air line oiler for the Vulcan #0 (0, OR) and the 80C hammers, from 1955. Vulcan eventually migrated to a tank-type oiler for the smaller hammers and a piston-fed oiler for the larger ones. You can see examples of both on this page.

Note: Tip dated 1 August 1980. Another presentation of this data is contained in the Onshore Field Service Manual. Click here for more details.
