There are 2 sources that I know of: Hobby Services (probably expensive) and another fellow in Florida that Frank Tiano recommended in RC Report but I can't seem to find the e-mail address.

do it yourself as it is easy. Get a set of good bearings from Boca bearing and a ring from Frank Bowman and go at it. Take off the head and the pushrods., pull the sleeve and thenb use a toothpick and drive it intothe hole in the back and pull out the wristpin. Take the case and heat it up in the oven and out coems the crank.
Use 1000 grit and sand with oil the inside ot he sleev, make sure the ring rotates freely so that there is no carbon buildup in the groove and re asemble. Make sure the clip is in the piston on the far side and to be safe buy another telflon pad and put it intot he hole that the clip fits in . In this way if the little clip would come loos4e it cannot go anywhere. Put it together in reverse and you have a new engine.

Hey!

Be carefull to note the position of the cam gear/cranksaft if you need to take off the cranck shaft. None of the posts that I have seen on the matter are correct. DON'T RELY ON THEM. Even if they come from OS.

No pun intended.
