'90 Polaris Indy Sport 340 Chaincase

Hi, I have a 1990 Indy Sport 340, looking for the chaincase gear bolt torques. I removed the bolts (grade 2, 1/2 inch) that were torqued to about 5 foot lb. I don't have a castle nut and cotter pin on the upper bearing, both gears have a locking washer to the gears.

Thanks
