T-190 What maintenance while tracks are off?

[JRP]

I have the tracks off for changing final drive oi. What other maintenance should I do while the tracks are off?

Inspect your rollers, front & rear idlers for any bearing wear. Should be no freeplay in the bearing.
When reinstalling tracks, I like to reverse sprockets side to side then turn the track end for end (leave it on same side). This moves the heaviest friction load (pushing forward) to opposite side to the sprocket tooth and track imbed.
