Just bought a disassembled AX-15. How hard will it be to rebuild?
 

Just bought an AX-15 and a rebuild kit that someone started rebuilding but they gave up after they got it all apart. I'm swapping it into my XJ to replace my AW-4, but I've never rebuilt anything more complex than a lawnmower engine or a differential before and don't exactly know what im doing. How hard is to rebuild one of these, any good how to's out there? Also will I need any special tools to do this, I have a good set of shop tools with presses and bearing pullers and stuff but I dont have many specialized tools. Well any help is appreciated thanks.
