Small Engines (Lawn Mowers, etc.): Craftsman 13 hp. 30 rider., dana model, ohc engine

Question
I have a used just bought Craftsman rear engine riding mower model number 502.256220 ser. no. 7288605652j00166 about a 1996 year 13 h.p.engine no. 143.961300
The book calls for a RJ4C plug  but it has a rn9YC in it which seems to be the right reach plug as it is a OHC ENGINE .And I can not find this engine in any plug charts .What plug is it really to have? I no the RN9YC must be a misprint.
Also what kind of grease does the DANA model 4450 5 speed trans axle take because I need to replace the brake pads and it looks like I need to drain it and split the unit in half to get to them.
Thanks for any help you can give.
Have a nice day.

Hello Again Darel:

>>Have them Cross the Plug Number with a Different Brand. It Does Not have to be a Champion Plug, an Autolite or AC Plug that Crosses over to the Champion Plug will give you the Same Performance.
