Nope, just oil it, grease it, and enjoy. Club member of mine did that way back when, as in when the only FO Tamiya was the brand new Tiger 1. He later went the full package, a FO King about 3 months before Tam intro'd the FO King. Your system will work well. His did for quite some time.
One tip, though. You may want to reverse all your track pins, to wit, remove them one by one and install them from the outside of the track, not the inside. On the inside, as some of the pins will slowly work their way out. one will eventually catch on something and rip the track link. Installing them from the outside seems to eleviate that problem. Also, it's easier to see one that is beginning to work out, and just shove him back in again.
