Caterpillar D4D aligning track roller frame with sprocket.

[Hollyrock]

Hello I have a Cat D4D 78A, does anyone have any tips for aligning the track roller frame with the sprocket on D4D, 78A?

I am getting some where and the track tends to fall off.

Front idler wear out /yoke seal leaking?

Front idlers are good. And I don't see a yoke seal leaking, if you mean the one in the middle of the equalizer bar.

So i have attached some pictures here. You can see the idler sits/ aligns more to one side than the other. The other idler on the other track of the dozer is centered between the yoke.
