Aligning Centurion engine to gearbox

[Malcolm Towrie]

John,
The tracks came new with 108 links. The users manual says when you use up all the threads available on the tensioner trying to set the correct sag, you need to remove a link. When you are down to 102 links, get REME involved.
That's 6 links you can remove, which surprised me since that's about 2.5 feet of track!
We've got 102 links on one track and 103 links on the other, so we're still good, barely.

The problem is when I loosen the tensioner nut off to slacken the right hand track, which is way too tight, the tensioner doesn't back off, even when I drive the tank in reverse. So it's jammed. Looks like I'll need to get medieval.
