SOURCE: 2001 Ford Sport Trac - Front & Rear Timing Chains

The rear timing chain (or "cassette" as it's called in Ford lingo) is the chain that drives bank #1 (passenger side) cam. The front timing chain drives bank #2 (driver side) cam. There is a also a primary "jackshaft" chain that is driven by the crankshaft in order to enable both banks to be driven through a common shaft. The reason for this peculiar layout is because this engine is a "derivative" of the 4.0L OHV V6 engine it replaces. Ford simply installed a dummy shaft in place of where the camshaft used to reside on the original OHV engines. But above all else, the job you describe SHOULD NOT be carried out by anyone unfamiliar with this particular engine. There are NO timing marks on any of the drive sprockets, nor are they key to their corresponding shafts. To time this particular engine requires use of FIVE dedicated Ford/Rotunda tools that hold all relevant parts in proper position. Failing to carry this procedure out correctly, will result in the bending of ALL valves with 100% certainty!!! Therefore, it is best left to a Ford dealer technician to carry out. If you would like more information regarding diagrams, TSBs, and procedures with detailed illustrations, please e-mail me directly with your FULL Yahoo e-mail address so I can attach PDF files. Hope this helps.

SOURCE: 2001 ford Explorer - engine rattling - is that timing belt/chain

What engine is this? if it is the 4.0L then talk to the dealer there is a recall on the camshaft drive chain hydraulic tensors, these will cause a rattle noise.

SOURCE: Need timing marks for 2002 ford explorer 4.0

There are no marks on this one. There is a special tool set to align camshafts ($900). The best you can do is to bring #1 cyl to TDC compression with both cam(valve) covers off. #5 cyl should have lobes at equal opening, exhaust just closing and intake just opening.. #1 cyl cam lobes should each be diametrically opposed to the positions of #5. If cams need to be moved, there is no registration of gear onto cam. Just loosen bolt holding gear and move cam. Retighten bolt. Roll thru 2 crank revolutions and check cam timing again.Simple.

SOURCE: how hard is it to replace timing chain on ford

There are 2 different 4.0L type engines on Ford Explorers if it is the VIN letter E (8th number reading left to right) then yes it has a timing chain on the back and there are 3 timing chains on the front. You will need special tools to hold the timing in place whille you change the chains. You can buy them from several different tool manufacturers. I bought mine from Snap-on but it was several hundred dollars and came with many different adapters for several different engines. But be prepared to spend a little money they aren't cheap even the small sets. Depending upon how much you'll use them you may want to see how much it would cost to have it done or try to find someone to loan you some. If you do then it's just a matter of following the procedure in the maintenance manual. As far as how hard is it? It isn't rocket science but I would make sure you read over the procedure in a repair manual, see if you can get the special tools you will need and depending upon your mechanical aptitude determine if it's something you want to tackle yourself. Good luck.

SOURCE: does a 2001 ford explorer sport have a timing belt

being that you most likely have a 4.0l s.o.h.c. engine you have a timing chain which only needs inspection around 100,000 miles for excessive wear on chain guides and leaking cam seals. this setup tends to last far beyond that mileage without any maintenence. if this was helpful please leave positive rating.

Setting of timing chains


Get Ford timing tool kit, part = otc-6488 (For about $119 USD on eBay)

4 timing chains (3 front including the optional balance shaft chain + 1 back)

2 cam guides (1 front + 1 back)

2 oil tensioners (1 front + 1 back)

1 jackshaft tensioner (1 front)

1 jackshaft guide/cassette (1 front)

1 balance shaft tensioner (1 front) (will probably be ok, so dont replace it)

1 balance shaft guide (1 front) (will probably be ok, so dont replace it)

new sprockets + bolts + gaskets etc.

new spark plugs + throttle body cleaner + lithium grease spray + oil change

head gaskets


some of these parts (the front stuff) can be obtained as a primary timing chain rattle noise kit Part# = 2u3e-6d256-** ab for 4*4 & bb for 2*4.

The kits also have later part numbers for us$ 76 @ http://www.fordpartsonline.com


My parts order (without the balance shaft stuff) was:

$76.04 KIT-TENSIONER TIMING 2u3e-6d256-ab

$47.93 Engine, Camshaft and timing, Timing chain, TIMING CHAIN, Explorer, Mountaineer, Rear - 4.0L SOHC - 4.0L SOHC

$57.36 Engine, Camshaft and timing, Chain guide, CHAIN GUIDE, Explorer, Mountaineer, Jackshaft To Cam - 4.0L SOHC - 4.0L SOHC

$103.22 Engine, Overhaul gasket set, OVERHAUL GASKET SET, Explorer, Mountaineer, Upper (Valve Grind) - 4.0L SOHC - 4.0L SOHC

$28.93 Engine, Camshaft and timing, Tensioner, TENSIONER, Explorer, Mountaineer, Upper - 4.0L SOHC - 4.0L SOHC

Its worth mentioning that this procedure is not enjoyable at all and should be undertaken with at least 8 full days to completion (I recon you could do it in half the time the second time).

It is basically on entire engine re-build with both heads off and the engine out of the vehicle.

It is not possible to do the rear chain or sprocket with the engine in the car as the flywheel needs to come off + at least 1 head, but it is possible to do the front primary chain and or front cam chain with the engine in the car.

You will be a ford exploder and timing expert after you do this - the main reason should be the love of your American built vehicle. Its a solid car - except for the plastic guides!

Disclaimer Note: This is how i successfully did the job, but i am not a ford mechanic and don't hold me responsible if this does not work for you.
Timing Overview

A Small Sprocket on the crank turns a larger (2 to 1 ratio) jackshaft sprocket that is in turn connected front & back to the 2 camshafts.

Thus a 360o turn of the crank will turn both the camshafts 180o.

Firing order is 1-4 2-5 3-6, Right side numbers 1,2,3. Left Side = 4,5,6.

At TDC pistons 1 & 5 are fully raised, thus 1 is about to spark & 5 is evacuated.

The engine will turn freely (no piston to valve contact) with the cams 180o out, it will even run (roughly) with 1 out 180o, any other settings may cause major damage to the valves.

The 2 cam shafts come with timing markings, "yes" real timing marks that anyone can use (even without special tools) to ensure correct timing.

The way to time it is to ensure both the off centre cam shaft slits are level/flat with the head.

With the engine at TDC both the cams need to have the off centre slot in the same position either up and level or down and level.

It is super critical that both the camshafts are 100% in sink with each other, i.e. not a few degrees off, the engine computer can compensate for crank timing but not engineering failure.

Be warned the camshafts can turn easily fast & hard by themselves as a few springs are compressed at TDC, I got my finger jammed and its still healing + if the engine is not at TDC you may damage a valve.

Now heres the hard thing that you will need special tools for - if you need to change the timing, you will need to be able to undo the cam sprocket bolt on both cams & these are done up real tight.

There is a tool that you attach that has 2 pencil thick shafts that fit into the sprocket and prevent it from turning - then you need to put about 90Nm of force on the bolt (remember the rear one if LHT)

For the $money$, its well worth getting yourself the tool kit - it will save you hours in the long run. Search eBay for otc-6488 should be US $119 - then sell them again for say $100.

There is also a tool version of the oil tensioner in the kit that screws right in and puts the correct amount of force on the chain + guide, to enable you to do up the cam bolt with the chain and sprocket in the right spot on the cam.

I have a Ford Explorer 1999. I have been told timing chain gards need replacing which are plastic. The motor need to come out to do front and back at $7,000 AUS.


Yes Ford Explorers are like that, The timing chain tensioners are plastic and need replaced with the chains. The engine has to be removed, please replace all chains and related parts at this time. This will save you money and downtime later. There are multiple chains on these Fords.

2001 Ford Ranger V6 timing chain


Hello;
The Ford motors are pretty good. I had 280K on a 2.9 V-8 that only needed the oil changed every 3K. Unless you have fluctuatuation in the timing then you should be ok.
These engines use a chain rather than a belt and have excellent life.
Thanks;
