Eaton HO72 Axle Shop Manual

[Joe P]

Good day all! Could someone direct me to a repair manual for the HO72 Axle? I want to replace my leaky pinion seal but cannot undo the large yoke nut. Yes, I did get the rusty cotter pin out completely and yes, I do have the leverage and correct socket, which I ground the OD to fit into the yoke and get full engagement on the nut. Thinking I can undo the flange bolts and pull out the pinion gear together with the pinion bearing but want to be sure there's nothing else like a snap ring or circlip holding it together. Thanks!
