Crankshaft/ Journal Grinding Goltens Advantages Over the past 60 years, we have applied our tooling and expertise to recondition over 25,000 crankshafts worldwide, as well as countless other rotating journals and shafting.

4 As the first company in the world to complete in-place crankshaft grinding in the early 1950s, Goltens ' tooling patents revolutionized the industry with massive reductions in downtime for owners. In-situ cutting M/E crankpin journal Continuous R&D and field trials have given us the best tooling for crankshaft/ journal machining in the industry. This allows us to perform large-scale jobs in a fraction of the time of traditional grinding, often with a single cut fillet to fillet with the highest tolerances. We apply our technology to challenges in the marine, industrial, stationary power and offshore sectors. We repair damaged journals on any and all manner of rotating equipment including compressors, turbines and other shafts. New tool removes these concerns with: In-situ grinding intermediate shaft journal Less Redundancy. Only one tool is needed for grinding, milling or turning. Simpler Repair Management. Depending on the engine type and the extent of damage, Goltens can choose the best possible method for repair.

5 Less Repair Time. Proven on board, the new generation tools reduce the repair time for a large crankshaft with more than 50. In-situ grinding rudder stock sleeve Page -1- IN-SITU MACHINING SERVICE. Crankshaft/ Journal Annealing Over the past 5 years, Goltens stations around the Class Approval world have successfully annealed over 75 crankshafts, saving Goltens has undertaken extensive workshop trials with customers tens of millions of dollars in unnecessary Class Society and select OEM involvement and subsequent crankshaft purchases, major engine rebuilds, as well as metallurgical analysis to demonstrate the results of the countless days of lost operational capacity. process. Loss of a crankshaft or any rotating shaft due to high Goltens has received job specific approvals for In-situ hardness values is a costly, time consuming, and extremely annealing of marine crankshafts from several Class disruptive occurrence. As the market leader in In-Situ Societies crankshaft repairs, we encounter many crankshafts with areas of excessive hardness each year.

6 Goltens Advantages Excessive hardness can often be machined away by Comprehensive capability to handle all aspects of Goltens ' In-Situ teams, provided that there is sufficient hardness treatment inclusive of engine preparation, remaining material to remain within manufacturer's maximum inspection, pre-Machining, hardness removal and finish allowable undersize. However, when this is not possible, the machining as well as only remaining options are either to scrap the crankshaft, or engine reassembly remove hardness by annealing. A large, global team of highly skilled In-Situ technicians to ensure a rapid, expert response anytime and anywhere Over the years, we have refined our process for Extensive experience successfully annealing crankshafts annealing crankshafts and other shafting, and can do this across a broad array of makes and models of engines and successfully in-place as well as in our workshops around the rotating machinery world.

7 Our deep understanding of the metallurgy, expansion Globally deployed and available portable annealing characteristics, and safety Precautions, has been developed and equipment for In-Situ application refined over the years, to create a safe, repeatable, highly controlled process.

Sometimes the damage is so severe that the engine pockets have been damaged and the engine requires line boring. We have invested heavily over the past decade to enhance and refine our world-class line boring tools for use in all single and multiple in-line boring applications across industry lines.
