Hi, Phillip Pfister.

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 sharing , just bought a d8 h , trying to prepare myself for all the common stuff

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.

At 4 min in the vid, those are guides. No seals. An its the equalizer bar

With as worn as those tracks are it can be done. Get to thevpoi t. Lot ad lib. Good luck
