Harmonic balancer weight and size

For starters, how does the weight and size of a harmonic balancer impact the vibration
and torque output of a diesel? Is bigger always better (weight and diameter), if the crank nose can handle it? I’ve been thinking about running a big semi truck balancer, something with the diameter bigger than 12.5”... |

The crankshaft harmonic balancer is sized to a specific set of pistons, rods, and crankshaft.
It is dialed in to that setup, similar to how the throws are balanced with the rods and pistons. Harmonic balancers reduce the vibration and stresses in the crankshaft to reduce the chance of it breaking at high torque output. The torque output will be the same regardless of a harmonic balancer being installed. Stronger crankshafts generally take bigger harmonic balancers. Viscous (fluid) harmonic balancers are more forgiving when it comes to tuning it to a crankshaft setup compared to a rubber harmonic balancer. If you are using a production crankshaft I would recommend talking to fluid damper to see if they can recommend a product for you to use. What engine did the damper come off of? What engine is the damper being attached to? Why not use what everyone else is using? |

If we all use the sameo - SAMEO, how can new products be developed and put in service, the guys out front mostly do not use what the back of the pack,(everyone else uses), parts. LOL |
