The shaft of the peg should measure .740" in length...They have a slight taper and are driven into the shaft...The opposite end to the head then appears to be 'staked' to expand it and lock it in the shaft...
The pegs can be driven out with a hammer and suitable punch...When refitting I use some retaining fit Loctite on the shaft of the peg and then restake the other end as well as I can...The head of the peg must be rested on a piece of shaft and then staked from the other end using a hammer and pointed punch...It's a fiddly job...Also, don't overdo it with the Loctite, if it gets under the selector fork it will lock it to the shaft...I haven't had one come adrift to date and you certainly wouldn't want that to happen...Damaged or more particularly, locked up gearboxes aren't a lot of fun! Russell Motors might be worh a call for new pegs, they have all sorts of small parts hidden away....
If anyone has developed a better/easier procedure for replacement I'd be interested to hear about it!....Ian
