CHALLENGE

During traditional press-fit operations, applying high linear force to the front of a crankshaft can push the shaft against the internal thrust bearings. This metal-on-metal pressure often leads to “pre-loading” or microscopic flattening of the bearing surfaces, which significantly shortens engine life and causes premature failure.

SOLUTION

Rather than pushing the balancer onto a stationary engine block, the Promess REMAP was programmed to utilize its unique Multi-Axis capabilities to pull the crankshaft into the balancer.

How It Works:

• Threaded Engagement: The REMAP’s rotational axis engages with the internal threads of the crankshaft snout.
• Constrained Force Loop: As the REMAP retracts, it pulls the crankshaft forward into the balancer while tooling holds the balancer in place.
• Zero Internal Loading: Because the force is localized entirely between the REMAP tool and the crankshaft/balancer interface, zero force is transmitted through the crankshaft to the thrust bearings.

Elimination of Bearing Damage: By isolating assembly forces, the engine’s internal components remain completely unloaded during the press cycle.

By pivoting from a “push” to a “pull” methodology enabled by the REMAP, the manufacturer achieved:

• Total Preservation of thrust bearing clearance and surface integrity.
• Reduced Warranty Claims related to crankshaft end-play and engine vibration.
