Hey folks! I'm, trying to replace my worn out super tigre g75 connection rod but I dont know how to take off the Piston Wrist Pin..any suggestions on how and tools needed?
It Goes Between the Crankshaft and the Piston Wrist Pin



Thanks!

You need to remove the snap rings in the piston holes the the conneting rod goes thru. http://www3.towerhobbies.com/cgi-bin...LXFY43&P=Z

awesome! thanks

You only need to remove one of the circlips then push the wrist pin through far enough to clear the rod. A big caution though, the rod only fits on the crankshaft one way so the new rod must be fitted to the piston exactly the same way the old one was so the piston goes back in the liner the same way it's been running. It's a bit hard to tell from the photo of that rod if it's the front or back that's showing but if you look carefully at the bottom rod bushing you'll see that one end of the bush has a very small chamfer on the inside. That end fits on the crankpin first so it's up against the crankweb, the chamfer is there to clear the very small radius machined where the crankpin joins the crankweb. The side of the rod where the bush is machined flat obviously then is towards the backplate.

I use tweezers with an angled end to get at the circlip tang and it's a good idea to do it inside a large plastic bag because if it springs loose it'll disappear into a black hole never to be found again . When you fit the circlip, turn it in the groove to make sure it's seated properly and have the tang at the bottom pointing up.

I've edited to add a pic of a rod showing the chamfer on one end and the flat on the other end.

got it tweezers did the trick!
