The service procedure of the main shaft sleeve requires a torque wrench and a hand-driven oil pump to release the main shaft sleeve. With our oil pressure-driven “pop-off” release solution, we’ve reduced the risks to workers, eliminated the grinding and heating procedures, and shortened the turnaround time. It’s safer, simpler and quicker.

No grinding. No heating. 80% quicker turn around*
