First off I need to be up front about not having much experience with dozers even after working on heavy equipment for over 40 years. 90% of the equipment I have worked on has been either front end loaders and haul truck in the 30 to 65 ton range.
In all these years I think I replaced a track adjuster on one Cat dozer. So now with just over a month till I retire seems like I have been working on dozers at least half the time!
To get to the question/problem that came up just before quitting time today. D6D LGP 6X00408 right track very loose, operator attempter to adjust it and it only held till he moved dozer. Walked it down off hill and to wash bay. Then we removed the guards off the track frame. So much wet clay under covers it looked like the covers were still on!
Another shot at the wash bay and from what he said most of the gobs of grease were inside the spring area. I was hoping the leak was going to be something simple like the grease fitting had come loose. As it was end of shift and also end of work week for us have not had chance to pump grease in to confirm where it is leaking out.
A quick look in SIS and it appears that if the adjusting cylinder is the problem we will have to drop the track off to get the front idler to move forward to have room to remove the cylinder. Just looking for advice if that is correct. I did see where the manual says to compress the spring by outting a pin in the sprocket and then run the nut on some to hold the spring compressed. As nasty as this thing looks I'll be surprised if that nut will ever turn, any safe options to go to in that case?
I recall a detailed project someone on this forum worked on last year but so far have not found that thread, anyone able to point me in that direction?
I will be getting back to this project Monday morning so I was hoping to have some good ideas of what way to go so I look as smart as some people think I am:D
