Mr Fro Posted May 29, 2015 Share Posted May 29, 2015 You mean the gudgeon pin?You'll probably need to heat the rod up to allow it to release the pin. Quote Link to comment Share on other sites More sharing options...
fq-craigus Posted May 29, 2015 Share Posted May 29, 2015 Like above, heat will be needed to expand the piston and then drift the pin out Quote Link to comment Share on other sites More sharing options...
megawatt Posted May 29, 2015 Share Posted May 29, 2015 Buy or hire a gudgeon pin removal tool. Don't lean on the top of the conrod or you will damage the big end bearing. Quote Link to comment Share on other sites More sharing options...
oldie59 Posted May 29, 2015 Share Posted May 29, 2015 Like above, heat will be needed to expand the piston and then drift the pin outRead that as gentle heat, too much can deform the piston. A cloth/tea towel dipped into hot water then wrapped around the piston and left for a few minuites sometimes works. Quote Link to comment Share on other sites More sharing options...

Well pointed out, i would have thought no one would heat it until cherry red or melting though Quote Link to comment Share on other sites More sharing options...

megawatt Posted May 29, 2015 Share Posted May 29, 2015 You won't deform the piston unless it gets close to melting point. Use a proper tool to push the pin out or you will damage something. Quote Link to comment Share on other sites More sharing options...
