As far as I know I don,t think they list it for them so just go by a nominal torque sheet for it. If you don,t have a sheet usually hardware stores have them or post the size of the studs and we,ll come back with it.I have rebuilt dozen of the starting engines on Cats & just tightened them up till they were good and tight.After doing so many you know when things are tight but not over too much so you strip the threads.
