pt 1, D8H CAT track adjuster, tear down detail

[@dplant8961]

Hi, Phillip Pfister.
Good video. Thank you.
I had the good fortune to assist a VERY good field mechanic put new seals into a track adjuster on a 36A D8H in the field - without even breaking the track. It took a little work with a 20-ton hydraulic jack to push the idler all the way forward and it was tight getting the adjuster cylinder out but it did come out.
I suspect that it would not be possible with track pins and bushes in good condition but these were about 60-70% worn.
The 'bar that you are referring to is called the equalizer bar.
Just my 0.02.
You have a wonderful day. Best wishes. Deas Plant.

Don't need to take the track " off " but of course you need to unbolt / separate the track. You can use a BIG bottle jack sideways to push it apart so You can get that grease filled piston housing ram out and double seal inner piston out. Take a chain hoist come-a-long to pull it back together to bolt up the flanges. Check the track links for break - cracks that need welding repair while you're at it.

Thanks for the info. I have a 977H I'm going to give it a try without breaking the tracks. We will serif that works.
