If you have a puller laying around you can use it.You just need two m8x1.24 mm bolts for the gear.
2 rear lower pump bracket bolts
4 ip bolts
keyway with #ers and arrow point to rear of pump
preliminary pump nut 22 lbs.
4 pump nuts 32 lbs
pump nut 125 ft.lbs

Lol, maybe need to go into it a little more. The breather on the front of the engine take that off and you will see the pump nut. Take the pump nut off and you will see a line or whatever match that up with the TDC line on the engine cover. Just bar the engine over by the alternator nut its alot easier.
take a paint marker and paint the front of the keyway white, helps to make sure it lines up right.
you will also need a mirror and a good flashlight to check the keyway.
