Chains & weights wheel weights and steering gear lube for Ariens a20va46 (Husq)

Hello,

Just got a new Ariens and lubed all the fittings with the purple stuff, but I can't decipher how to lube the steering sector gear teeth. Can anyone help? Also, is there a set of wheel weights that "match up" to the 20" rear wheels... the wheels do have pre-drilled holes.

Thanks much,
Ken
