Hi guys, just fitting another reg to a s400 and have been having real issues removing cylinder from block, after a good few trys useing many methods I thought this sucker must be welded on 😄

Then had a brainwave, I installed a short caphead allen bolt into stock mount and screwing in snug, I then used an automotive oil filter removing tool with the fabric strap, held cylinder in vice between two rubber pads and then wound out block as fabric gripped bolt head, hey presto

Hope this may help anyone else stuck with a tight one

Chris
