Here is my final installment.
I initially used Loctite 263 High Strength Threadlocker (red in colour)

but wasn't happy with the result for use on the cam sprockets. After rebuilding the engine using the Loctite I then tried an experiment by applying the Loctite Threadlocker to two washers which were left compressed together in my bench vice for two days. When the vise was released the two washers just slid apart using finger pressure.
So after a trip to an Auto Store and some good advice to use a special Retaining fluid Holdtite Retainer R62 (green in colour)

I repeated the experiment. After just one day the two washers could not be parted using fingers. It took considerable force as the shear strength was enormous.
Thus the engine was reassembled and retimed for the third time but now using the R62 Retaining fluid on all the friction coupling points, ie the timing chain sprockets, the cam sprockets, the jackshaft sprockets etc.
Today the engine was 100% back together again. With the fuel pump fuse (#3, 20A yellow) removed and the ingintion plug pack disconnected I cranked the engine many times to get the oil circulating and more importantly pressurising the Timing Chain Tensioners. Then after the fuel pump fuse was reinstalled and a plastic hose placed over the fuel rail test port, petrol and air were expelled each time the ignition was turned on as the fuel pump then runs for a few seconds.
Finally the big test. Will it start and run?
To my amazement it started instantly and ran as smooth as a baby's bottom. There were no rattles from the chains and the engine RPM soon settled down to a normal idle speed. The engine sounds fantastically quiet and performs beautifully on the road.
The bonnet/hood is now back on and the whole project is done and dusted.
Thank you sincerely to the Ford Explorer Forum for all the help and encouragement. You assistance was much appreciated.
I hope my experience using the R62 Retaining Fluid on the friction couplings will help someone else. I would not do the job without using this stuff as the consequence of a slipped camshaft is just so catastrophic as I well know.
Thank you again and regards from Down Under,
Brian
