Flail Mower Caroni Flail TM1900BSC Bolt/Nuts Torque Specifications

[HoHum]

My searching skills must be really bad. Does anyone know what the torque specifications are for the bolts that hold Left/Right hand Support brackets for the back roller of the TM1900?

The bolt numbers, per Caroni parts diagram for the TM, are 7 and 19.

For some reason, my Right Side Support Bracket keeps falling off and I, subsequently, lose my roller and scraping bar...
