TS185 Crankcase Assembly Tool
 

I've inherited a ts185 dirtbike that requires internal repairs. The manual (Clymer Prod. Sevice Repair Handbook) says that I'm requred to use a special tool for proper engine re-assembly on my model, as well as the TS-125 and TC-125. I was wondering if the tool is requred, or recommended, since I would like to avoid purchasing a tool I would use very rarely.
