Hi Paul,
sorry the reply took so long,didn't get the email on post replies.
On my micron delta the hex bolt on the exit end cap was removed and after a bit of tapping with a rubber malet it popped off,then just cut and shut as i described,don't know how old yours is but it may be fused together,the micron delta's are designed to be repacked or repaired and there are many replacement kit's on ebay to rebuild the can if you damage something like the rubber seals,quite cheap too,good luck with your can.
regards,Mat
