ENGINE REBUILDING - CRANKSHAFT

| Four indexing locations on the head stock with the air operated index pins make it faster to dial in the crankshaft properly. Easily adjusted outboard counterweights never need to be supplemented by inboard weights. These machines are built very heavily with widely spaced ways to assure positive alignment of the wheel head to the table. Moreover, the controls are easier to use. Precision Incremental In-Feed Lever is much easier to use than a hand wheel to achieve the precise desired journal size. |
