I'm restoring FT10S Johnson. It has GT 115 gearcase.
Does anyone know what is the torque on the pinion nut?
There are two pinion gears and nuts.
Attachment 61967Attachment 61968
I understood that Speedmaster pinion nut torque is 70 Nm and with Loctite.
70n-m = 52 ft-lb seems high for such a small nut (from what I can estimate in the pic) yes on the locktite. Get a firm reliable answer on the torque.
Now I have other problem with that lower unit. I don`t know what is correct load on the driveshaft when adjusting upper gears. Does anyone know?
