ive done a bunch 0f c 123 wet sleeve mototrs and been around or helped with a bunch of h sleeve jobs. we usualy use an old piston (this process usually ruins a piston and the rings for sure) put a ring in the top groove, bevel side down. compress the ring, and put the piston down into the sleeve, go to the bottom till the ring pops out.be careful as there isnt much room between the botom of the sleeve,and the bottom of the bore. we make a fake connecting rod about one and a half times the length of the real rod out of tubing. just weld a t on the top, then put a bottle jack under both sides of the t, and pump them up. the sleeve usually walks right up. usually have to use a new ring for each piston. i have only had one i couldnt get this way, and it was a newer job, with green loctite holding them in. a former ih mechanic came to the rescue,and said this was the second hardest sleeve pull he had ever done. the first hardest he said his puller base went down through the top of the block ruining it. when i did my 300, i took it to the loclal machine shop. i was putting thinner sleeves in, and didnt want to worry about breaking a new one.the machine shop only charged about 35 bucks to switch sleeves.i also had them put in new cam bearings, which i didnt have the tool to do. a 10-20 block may be a diiferent story. it might be a little much for the average machine shop.
