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.

Have you had the dozer for an extended time and was the problem with the tracks showing when you first got it ? It could have a bent dead shaft or broken one .

Idlers look really thin!
