Identifying the Master pin on my IH 100E

The track adjuster seals went out on my right hand track. I am trying to find out which pin is the master pin. All the pins have a bump on them, therefore; making it hard for me to know which one is the master. Can someone please offer some insight.
 
If the track has been off before, look for hammer lick marks. Consult your manual, it might tell you what to look for, like a shorter pin, or different front edge profile on the inside of the pin. Also look for different bolts on the grouser plate, might give a clue!
 
If you are sure that all the pins ends are the same it may have SALT chains fitted,with that type track you do not remove any pin,the track link splits by removing the four pad bolts from the joining link,look at all the chain links,if you find a solid one thats the joining link,remove the four pad bolts to split the track.

ok, thanks for all your help. i located the master pin. Now comes the task of knocking it out.. any hints? other thank penetrating oil, heat and a big hammer?
 
I made my own track press, a short piece of H- beam with a base welded on one end and wing with a piece of pipe on the other end for the pin to pass through, my 30 ton jack works laying down to provide the force. Also made a cap with a piece of shaft for the jack to push the pin. Sometimes heat is still needed. Some hydraulic jacks only work laying down if the pump is on the bottom. I think I was able to use this on the idler sliding the wing end between pads so didn't have to remove any pads. Good luck
 
On m cat I took one pad off and cut the link into.When done weld back together.I also welded a small plate between each pin for a little xtr strength.Aint botherd in 3 yrs. Hoss
 
ok track is off i removed the adjuster. Now im trying to figure out which way the seals go... there were no seals left in the adjuster. I know the one is the final seal and it only goes one way but i dont know which way the "cone shapped" one goes
