In high precision engine manufacturing, hidden risks can exist even in well established assembly processes.
One example is harmonic balancer installation. Traditional press fit methods push the balancer onto the crankshaft, transferring axial force through the crank and into the engine’s thrust bearings. While the damage is often invisible at assembly, it can lead to increased end play, vibration, shortened bearing life, and costly warranty claims later on.
A manufacturer partnered with Promess to eliminate this risk by rethinking how force is applied. Using the Promess REMAP, the process shifted from a push method to a pull method. Instead of pressing the balancer on, the REMAP threads into the crankshaft and pulls the crankshaft into the balancer, while tooling holds the balancer in place.
This approach creates a closed force loop entirely between the REMAP tooling and the crankshaft to balancer interface. The result is zero axial load transmitted into the engine block and complete protection of the thrust bearings.
By isolating assembly forces where they belong, the manufacturer preserved thrust bearing clearance, reduced vibration related issues, and lowered warranty claims, all without sacrificing production efficiency.
Smarter force application leads to better engines.
Sometimes precision is not about pushing harder, but pulling smarter.
