4.0 Engine Tjming Sets

[brianhood]

Hey Everyone,
I’ve read horror stories about people using non-oe ford cam phasers and timing parts on 4.6’s and 5.4’s. I’m going to replace the front and rear timing set on my 2002 4.0 engine that I pick up. I can’t seem to find any Motorcraft or Ford parts. All I can find are off brands. Has anyone had and good or bad experiences using Cloyes or other off brands of 4.0 timing sets?

Here is a nearly complete list of Ford part numbers for the job. The cassette kits include the guide, sprockets and chain. I don't now why but the front kit included the lower bolt with the O-ring but the rear one did not. I reused the rear lower bolt but replaced the O-ring. I recommend using a Viton O-ring.

I can't find the part number for the Crankshaft/Damper bolt. It is a TTY bolt and is supposed to be replaced. I could not find it online and went to my local Ford Dealer for it. They had it in stock.

You don't need to the Pan Gaskets if you don't replace the Balance Shaft Tensioner and Guide. My Engine did not have the Balance Shaft, but I replaced my Oil Pump so I still needed the Pan Gaskets.

I highly recommend replacing the Chain Tensioner and Guide for the Chain that goes from the Crankshaft to the Jackshaft. My Tensioner was totally broken off. I replaced the Chain too. I wanted to replace the Crankshaft Sprocket but the one I order and was told was correct caused a misalignment. Maybe it was for an engine with the Balance Shaft. My old Sprocket was still in good condition, so I reused it.

All these prices are from Village Ford. The were slow in shipping but had the best prices.

I don't know about the Cloyes parts. I have heard they are good but have no experience with them. I just prefer to go with OEM whenever I can. I have heard that you should at least use the Ford Tensioners even if you use the Cloyes cassette kits.

Since I’m on my phone, I can’t if you have an OHV or and SOHC engine. Based on the year you posted, I’m going to guess you have an SOHC.

You will need special tools to do the job if that is the case. Fortunately, tool kits for that job have greatly come down in price and are available on amazon.

I would also check out some videos on youtube so you know what to expect. Fordtechmakuloco is one. I’m sure there are others.

I studied the Fordtechmakuloco YouTube video over and over before I did mine. Fortunately, my brother in Kansas had the correct tools for the job and had done it before. He did it without removing the rockers like is done on the video. I am not sure why they remove the rockers unless it just makes it easier to rotate the cam. I think it may make the timing a little more precise but my engine runs very well without having removed the rockers during the cam timing.

The video has some very helpful tips for doing the job. Not all the tips were needed for my engine though. The video shows how you can take the new front cassette apart to make it easier to drop into place. I decided to try it first without taking it apart and it fell right into place. So, it is a good idea to check first. Not all engines are alike. The video tip for taking the old front cassette out was very useful and made it a lot easier.
