Morning all:

I know im not the only person in the world that has found this problem. I recieved a YS 140FZ motor and one of the pushtube sockets on the crankcase where the tushtube o-ring goes has a small chunk chiped out of the casting, so the o-ring wont stay in place or hold tube correctly. My question short of a new case I would like any advise as to how t fix it .
thanks for your time and experience.
see attached photos. one is of chiped place and other is of normal one.

thanks again

How about useing some jb weld? Might work i'd try it if it were mine.

I second the JB Weld idea if you still have the little broken off piece. I used JB Weld on a broken off cooling fin on a 50cc gas engine and it's held for several years now. This should get you the YS Support forum.http://www.rcuniverse.com/forum/forumid_197/tt.htm

Go over to giant scale and punch up gas engines then at the top of that is A thread for glow engines, when you get there you can go right into the manufacture direct. I know there is an easy way to get there but I don't know what it is so I have to do this.
Is this A new engine?? If so just send it back!!

This is an easy fix with JB if you have or don't have the piece.

Ok Guys here is my repair , I haven't painted the jb yet and its not totally Cured to do the finish work but ii think it is going to work.
After getting the correct size filler 0.350t tubing I coated it with silicone mold release spray. let it dry got the tube plumb and square with the other pushtube locked it in place with the head. took some aluminum duct tape to make a cup for a larger fillet to have extra strength,.
let is setup over night. 6 hours.

removed the tape and tubing, filled to little imperfection i had inside the cavity where the original chip was missing from, added a .90t aluminum strap half way around the pushtube standoff, glued it on with more jb weld let it setup for 6 hours. did a Little rough trimming to get what you see here, after it cures tonight and tomorrow i will final finish t Had drop a little aluminum paint on it just to camouflage it.

The O-ring fit nice and tight and are as perfectly round as i could get it with my end mills.


comments are welcome.
