  March 30, 2024 at 6:57 pm Tony, thank you will first start to confirm true RPM with strobe light. P & SB engine RPM currently the same at idle. Only P engine vibrates in idle and when in gear. SB engine no problem. I am not sure the connection between Cummins engine and Twindisc gearbox configuration? Damper plate? Springs? Rubber?

Of course the sellers, of these say different, but 30+ yrs of field experience work with 100’…

  May 14, 2018 at 8:11 pm Awie, This is not an IMO, take this as FACT…..
