    You do need the timing tool kit to replace any of the timing chains or cassettes etc. Loosening one cam bolt or jackshaft bolt lets the timing go. It's an infinite timing setup, the parts don't have any splines or gears, just smooth round hole against smooth shaft, held by the tightness of the bolt.

    hey guys we have talked about removing the balanced shaft but it looks like you have to remove the oil pan to get the tensioner iut or am I missing something?

    The BS tensioner is in the front/bottom. You can easily remove the chain from it with care.

    I knew where the chain was it wont come off unless you remove the woodruff key in the crank. I cut it with bolt cutters

    I see that its being suggested that all 4.0s made after 09 have the balance shafts in them whether used in a 2wd or 4wd. IS that correct? I am looking at a 2010 4.0 for my 4wd explorer. ANd is a "N" designation for a Mustang meant to signify that it does not have the balance shaft or is that something else? Thanks and good day.

    I just put an early 4x4 motor in my 01 explorer sport trac. I just cut the counter balance chain because its not needed on the 2wd. mine runs fine.

    I just purchased a 2003 Explorer XLS 4.0 2WD Flex Fuel model (I had no idea there was such a thing as a Flex Fuel model). When I took the timing cover off, to my surprise, there is a balance shaft. Any way to determine if this is the original motor by the cast numbers or any other markings on the motor? I'm curious to see if the motor had been replaced with a 4x4 SOHC motor.

    All 02+ 4dr explorers have balance shafts reguardless of 2wd or 4wd I have seen (easily 50 by now). I'm actually working on an 05 2wd now and it has a balance shaft chain.

    There's a stamp on the back of the block above the bellhousing for actual build date. Its a rectangle box. I've found the date stamped is usually a week before the date printed on the valve covers. If your engine is very rusty it'll be impossible to see. You can kinda see it in this pic, it's below the passenger head.

    is it possible to transfer the balance shaft from a 4x4 to a 4x2 engine?
    i bought an engine based on the vin number (E) and it is still to be delivered but i am thinking on replacing all the timing components prior to installation even tho the engine has only 60000 miles on it.
    at this point not sure if the donor vehicle was a 2x4 or 4x4.

    Ditto, I trust others here saying the balance shaft isn't needed. My 99 work truck I don't care if there is any slight vibration from the engine, if that is possible to feel. I'm removing the balance shaft chain when I get there.

    I'll just add that Mitsu owners have been pulling Balance Shaft Belts & deleting Balance Shafts for 20+ years with only GOOD effects - In a typical 2 Liter 4cyl Mitsu all u get is the normal vibe at idle u wd get fm ANY 4cyl designed w/ no Balance Shafts - Above idle there's very little if any difference in vibes - The biggest prob w/ Mitsu balance Shafts is that Balance Shaft turns at TWICE the RPM the Crank does so its prone to Bearing Failures... & that takes out the entire Motor when it throws Balance Shaft Belt & that throws Timing belt & Valves start hitting Pistons in keeping with a long standing Mitsubishi Kamikaze Tradition - Deleting Shaft & Blanking the Bearing Oil feed holes gives better Oil Flow for the Crank & Head - But Deleting just the Balance Shaft Belt in a Mitsu can save u some money too.

    DON'T CUT THE BALANCE SHAFT CHAIN

    cutting it allows metal flakes into your engine. It comes apart easy enough just PRY it apart..... this way you can catch all the bits from the one link you pry apart and no metal shavings.

    Below is a photo of my engine with no balance shaft.

    And here's a photo of CDW6212R (Don's) engine.

    It looks like both blocks have the bosses to mount the balance shaft but I wouldn't bother. The balance shaft is balanced with the engine at the factory and I doubt a local machine shop would have the equipment or the experience to balance your engine with an added balance shaft.

    Clean new parts are great, fewer parts help too.

    BTW Dale, were the jackshaft bolts TTY? I bought a new balancer bolt($3) last week, but couldn't remember if the jackshaft bolts were also.

    Even though the jackshaft sprocket retaining bolts are torqued in two stages they are not listed as TTY bolts. The following thread may be helpful: Solved - SOHC V6 Torque Specifications

    Thank you for the info,
    I got another engine with 60000 miles on it.
    I am thinking on replacing the upper and lower oil pan gaskets as well as the timing cassettes just because it will be already out and hopefully won't have to mess with it for a while.
    Does any body knows how many miles before the timing cassettes can became an issue?
    My vehicle is an 2006 and I am replacing it with a 2008 engine, I know that ford corrected or redesigned the cassettes but do not know in which year that iwas corrected.
    I am hoping someone has an idea of what year the correction was made and hopefully I won't have to make any changes and just install it as it is.
