If the front torsion damper fails the crankshaft may break.
I would suck it up and follow John Deere's advice and put on a new or rebuilt damper.

"Pennywise and pound foolish" comes to mind.

"A torsional damper, also known as a harmonic balancer or vibration damper, is a crucial engine component designed to reduce torsional vibrations in the crankshaft. These vibrations are a natural byproduct of the engine's operation, caused by the reciprocating motion of pistons and combustion forces. By dampening these vibrations, the damper protects the crankshaft from excessive stress and wear, improves engine performance, and enhances overall durability.
Here's a more detailed explanation:
Purpose of a Torsional Damper:
Crankshaft Protection:
The primary function is to protect the crankshaft from torsional vibrations, which can lead to cracks or even failure over time. "
