Track tension seal replacement

Hey guys, been a long time.

Some nice person here posted the service manual pages on how to change the track tensioner seal on my D6-B 44A###### quite a while ago.
Dam, now I finally get the time to fix it, I cant find the file!

I loaned my service manual to someone and it never came back, neither did he😠

Greatly appreciated if someone could post how to do this before I start removing bolts. That spring looks pretty deadly!😮

Thanks.........

Oh and I might need a bit of help in replacing the front idler from a 9U I got for parts.

Free parts if you want them from the 9U. Just keeping the finals, clutch packs, and spur/crown gear.
