Does anyone know where I might buy the spx 303-540 valve bucket tool?
It seems like a good Idea because it depresses 2 valve buckets at a time

 

Here is a example:
Product Catalog - TAPPET HOLD DOWN TOOL TAPPET HOLD DOWN TOOL 303-540


I think I have the same tool, its just a long time ago I used it, and then only 1 bucket at a time.

 

The bigger question is:

Where do we get the shims?!

When I raced an eight valve Fiat back in the 80's, I had a complete shim set in stock so I could do the whole adjustment in one sitting.

With 32(!) shims now, and them being "Jaguar" shims, I can't imagine what the cost of a similar set might be. Which means I would have to remove, measure and re-install all the shims; then go to the Jag dealer to either buy or place on order the ones I needed; then go at the engine AGAIN to install them.

Sheesh....

 

I would think you could get them from Ford. Since the 4.0 and the 3.9 Ford have timing tensioners and chains are the same. If not check with a shop that reworks heads they should sell you some.

 

I would suggest that you use the tool for the intake cams and remove/install the exhaust cam to replace tappet shims.

You can remove the intake cam also but the front cover needs to come off. (alot more work)

It is easier/faster to remove the exhaust cam than to use the tool. (it is tedious)
After you swap a few shims on the intake cam you will see what I mean, take my advise and just pull the exhaust cam after measuring.

The shims can be ordered from the Jaguar dealer but they are a little 'pricey'.

I never priced them from a Ford dealer.

The trick is getting the shims out of the buckets

 

You are CORRECT SIR!!!!!

I usually spray some solvent to lower the oil viscosity between the shim/tappet and blow compressed air in the edge to ATTEMPT to dislodge the shim.

A strong magnet might help also and it will work fine if the cam is removed.

Is not the risk of using a magnet that you finish up with a magnetised bucket/shim? Not very magnetised, but enough to attract metal particles from normal wear and tear, right onto the loaded surfaces!
