G clips are a bit tricky to say the least. BEFORE starting put on eye protection. They will FLY if they get loose while being pressed into piston…one left a grease spot dead center on lens of my glasses. (polycarbonate actually) I am sure the real pros have tools and techniques unknown to most in hobby, That said,,, I will share a method that usually gets the job done. I will warn you TOOLS are involved… probably tools you can aproximate from stuff already cluttering up your work area.
Tool #1 a wood handle scraper Tool #2 a short piece of brass rod with a square end the same diameter as piston pin Press the end of G clip into grooves in piston pin hole, use the rounded end of wood handle to force the G clip into hole, then use blunt end of brass rod to seat clip in groove. Be very aware that C clip is compressed and ready to fly until it is firmly seated in the grove. Groove should be cleaned if neededl I ASSUME that if needed G clips from other motors with same diameter piston pins might be suitable.
Will pose and post photos to illustrate later. About all the instruction a manual provides is “reassemble in reverse order”
Note: there may be a better way. It took a couple tries to get the G clips to cooperate.
Why brass tool? Because I had brass stock, easy to machine and reasonably durable.
