84 XJ6 Timing Chain Question
 

The head removal continues apace, and I am finally getting close to trying to get the !$%#$&^ thing off the block. I have the cam covers off, and I'm getting ready to slacken the timing chain to disconnect the sprockets.

I loosened the nut on the serrated plate, and was able to get the pin depressed to be flush with the plate with a couple whacks. I can't get the plate to turn, however. Am I going to need the tensioning tool at this point as well as later when I retighten the chain? If so, where is a good place to pick one up.

Thanks!

Most Jaguar specialists should have the adjuster tools, they don't cost much. If you can't move the disc, take the nut off and try tapping lightly with a small hammer. The adjuster will seize up after the car has been standing for many years; it had on a 2.4 Mark 2 I rebuilt in the 80s.

Use some dismantling fluid, or WD40 as well.

I made this one, and I was able to get the wheel to start to turn. It got tight after less than a 1/4 turn, and then the center nut in my DIY tool started turning in the washer assembly.

I'll hose it down with WD-40 and see what happens.

Thanks!

Never mind! I expected the chain to get a lot looser. It looks like I got it!
