D47u track master pin?

I need a pin pressed out of another machine next week and was wondering how a D47U comes apart.....pressed as well? I believe one side needs a idler bearing and might as well do both while the guy is here.

Some D4's had split end pins with wedge plugs. Unless it has newer rails with a standard pins.

look for cork in the end of the wedge plug--if so remove it and there is threads in the plug to pull it out

Here is what the D4 Tractor Servicemen's Reference Book, form FEO30521-02 says:

Seems unlikely that a 7U would still have one of these style track pin systems - probably replaced with a drive in/ out pin.
