Hi,
I have a '69 450 that needs some steering clutch work done.
I am trying to get the master pins out of the links but they don't seem to want to budge or move at all.
First, I do have both snap rings off of the pins. The tracks are positioned as per specs - at the rear and about approx. at the corned of the gearbox. I do not have oxy-acetylene and am using a tiger torch with propane, to put heat to the plates. I have tried driving the pins out with a sledge and drift but they don't want to move - yet .
So, what do you experienced owners use to remove your "master track pins" ?
I am thinking heating and then maybe using a hydraulic jack - providing it is properly supported and positioned.
Any advice would be very welcome - I am in a bit of a bind and the weather is starting to get very wintery now .
Thanks in advance

It sounds like you are doing the right things....just have to get bigger and rougher with it! Not to question you, but are you sure tension has been taken off the tracks?
One more trick...I think someone has mentioned before about using dry ice on the master pin as well as heating the link. May want to see what others say!

Steve,
Thx for your comments.
Today I have managed to loan an oxy-acetylene set, so I might do a bit better now.
Re heating the links. I assume that they are heated with the pads still attched by the four bolts? How about removing the pads either side of the master pin as it would make heating much easier, as well as making access to the pin better. Using a sledge on the links without the pads on - would that be likely to damage anything as I am sure the pads takesoe of the force from hammer blows etc.? The bulk of th force would be bsorbed by the thick sprocket wheel?
Any other pointers would be greatly appreciated.
Thanks
