If the tensioner only holds up the chain (keeping tight) and it is only installed with two bolts. Why the need for all the special tools, if you not removing the chains?

I can understand making sure it is at TDC, but why take of the chain gears?

From looking at the pictures, it should only be a R&R (remove and replace).

 

You don't need all the tools if you are just replacing the secondary tensioners.
You can use the zip tie method details here https://www.jaguarforums.com/forum/x...ics-faq-52653/

 

That much better than trying to source the tools, by Friday.

There is one thing that I will do that wasn't done in the post, is position the engine at TDC.

Thanks, to you and the creator of the post.

 

Top dead center has no relationship to cam timing. When the cams are locked with the alignment tool the number 1 cylinder is, I believe, 45 degrees past TDC.

With the zip tie method the exhaust cam should be positioned so that all the lobes are off the valve stems, at least as much as possible. That eliminates pressure on the cam which, in worst case, can break the cam when loosening or tightening.

 

Dummy that I am, I just went in, tied the chains down, lifted the exhaust cams and replaced the tensioners. Looking back, I suppose it would have been safer to position the cams so that the tension is off the valve springs. In any event, all went well with the correct tensioners, tensioner bolts, spark plugs and gaskets.

 

This may be a good day to buy a lottery ticket. Then again, maybe you used all your luck for today and should now get in bed until tomorrow.
Seriously, as long as the cap bolts are backed off and tightened in small increments, and the cam checked for binding during the process, it is possible to complete the process without too much risk.

Thats the reason I want to be at TDC, I don't seems to be having that much luck this month with all that is happen. Its good to have a strong will and mind.

 

It is far safer to rotate until the exhaust cam is not under tension. After reassembly the engine can then be rotated to ensure the cam flats are in alignment.
