In this application, Promess utilized the REMAP Multi-Axis Press System to enable a more controlled harmonic balancer assembly process—eliminating thrust bearing damage common to traditional press-fit methods and extending engine life.

Protecting Thrust Bearings with a Pull-Based Crankshaft Assembly
Press-fitting a harmonic balancer can be a complex process. In conventional assembly processes, high linear force applied to the front of the crankshaft pushes the shaft against internal thrust bearings. Over time, this metal-on-metal contact causes microscopic deformation, reduced bearing clearance, and premature engine wear—often surfacing later as vibration issues or warranty claims.
To solve this, Promess utilized the REMAP Multi-Axis Press System with a completely different strategy. Instead of pushing the balancer onto a stationary crankshaft, the REMAP was programmed to pull the crankshaft into the balancer using a precisely controlled, closed-loop force path.
This shift from a traditional “push” method to an intelligent “pull” process allowed the manufacturer to preserve thrust bearing clearance, protect surface integrity, and significantly reduce warranty exposure related to crankshaft end-play and engine vibration.
