ITO is a genuis!!! Time to break out the HH135!!!

Yup, on a old bad 87/na housing. Next time I go over to my buds house I'll bring along the housing and give the MIG welder method a try. Thanks for revealing your secret.

Glad I could be of help.

Thanks Judge!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I was VERY interested in knowing a trick for this one since I had been putting off pulling a sleeve from an old housing for the engine I am about to build. I once had luck with a self tapping screw that would go in just far enough to catch and allow you to pull the pin with a pair of sidecutters, but that was ages ago and I haven't found any that work recently. Those pins are hard!



I just went downstairs and tried the Ito trick. Took me less than 5 minutes to pull the sleeve without doing damage to anything except the 2 rolled pins!



Thank you!!! https://www.nopistons.com/forums/pub...1047683894.gif

I was thinking not to give up my homemade tip, but after taking into consideration how hard does pins are to pull out, I felt it was my rotary engine civic duty to help my rotary engine brothers. JLB I'm happy you already saw some success with the ITO-Spec PIN pulling trick https://www.nopistons.com/forums/pub...IR#>/bigok.gif
