So I am trying to take my tailshaft off to change the drive gear for the speedo. I have everything off and it comes time to tap the drive pin through the shift block so i can realse the tailhousing from the main case. WELL IT SEEMS THAT THE LAST PERSON THAT WAS IN THERE F****** THE PIN UP AND IT IS MUSHROOMED OUT A LITTLE OVER THE TOP OF THE HOLE. IT ALMOST LOOKS LIKE THEY USED SOMETING OTHER THAN A PUNCH TO TAP IT IN AND WHATEVER THEY USED BROKE OFF IN THE HOLE. SO NEEDLESS TO SAY THE PIN IS BIGGER THAN IT SHOULD BE AND I CANNOT GET IT TO DROP DOWN. I HAVE TRIED DRILLING IT...SMASHING IT DOWN WITH A PUNCH...AND I CANNOT GET ANYTHING TO WORK...ANYONE WITH ANY SIMILAR PROBLEMS EVER PLEASE HELP???
