Thank you very much, it worked perfectly

I’ve done the same thing but I used 1/2 inch drive socket run the bolt through the socket works way better good video

That is also a torque to yield bolt holding the damper pulley on. TTY bolts are to be replaced after one use due to the stretch after torquing.

harmonic balancer installation tools are available as free loner kits at most auto parts stores.

A $500 harmonic balancer installer? Must be made of gold or platinum. They have them down at the local tool store for ~$40. Worth it. If this bolt method works then so would the tool.

Thanks for the tip, I was able to my explorer up and running after a timing chain failure.

Very great video

I changed out my timing cover gasket on my ford taurus, it took me five minute with my impact gun if you use your impact right just cant hammer it in every 2 second she was moving in slowly just before she settle i used my torque wrench and torque her down to 90 ft lbs didn't want the engine to rotate all i use was my 2 pullies bolts an a wrench and braced it against my water pump no leaks from the power steering pump, coolant or oil pan gasketlot of work everything came off the front of that engine, i paper bag parts and bolt that cam off with it the bags was itimize and number in the order they came off you definitely wont be left with any extra bolts all my pullies were lined up correctly couldn't figure out why my temp gauge was acting crazy but it was all because of that gasket the engine wasn't seal tightly. i have two friends work at ford they said it was safe to use a impact just don't lay into it just make sure it lube

Good ideas. Thank you.

My engine is in my truck (not on an engine stand). I don't have an impact wrench. When I go to loosen the crank bolt (using a breaker bar), will I be able to use the belt to keep the engine from rotating counterclockwise? Please advise. Many thanks!

Its funny a retired automotive machinist showed me this method of balancer install twenty years ago. I have not had an issue with a thread going south, but I always make sure that I'm 3/4 the way in the crank thread before any pressure is applied. If a person is really worried about causing thread damage with this method then they should buy the installation tool. /K&K

Yeah I wouldn't recommend reuse of that balancer then. If you can see through the balancer they can become unbalanced or spin as it were. Most balancers are made in a two piece design that once the inner rubber o-ring deteriorates the outer ring can slip a bit and cause a vibration that can wipe out the crank bearings. I like the 4.0L Ford balance but its still a two piece design that is subject to failure due to normal wear and tear. Dorman does make a replacement balancer for this engine. /K&K

What about the crank shaft that doesn't have a bolt in the middle of it.. how do you install a hormonic balancer?

Thanks, nice work

Does Ford recommend using a new crank bolt each time you do a final reinstall of the harmonic balancer?

Keith & Kevin's Repair & Restorations - Thanks! Adding an extra 90 or 100 degrees after a specified torque setting, in order to lock the bolt down, is usually a hallmark of Torque-to-Yield Bolts (TYBs). The following is a link to an article that discusses the differences between regular engine bolts and TYBs - www.hemmings.com/blog/article/the-lost-art-of-bolts-fasteners/ I am not a pro mechanic, but I have learned the hard way to determine the precise torque specs for what I'm working on, and whether or not a TYB is required by using one or more of the following: a local or online parts store; either a factory parts website or printed/electronic shop manual (if available), factory TSBs on the internet, a free online manual though the public library, a Haynes-type manual(borrow from a public library or buy through Amazon or Barnes & Noble), online through a paid subscription to Alldata or Mitchell's, or by using an on-line forum whose members know about the vehicle/motor type. Some car makers let you buy a limited block of on-line time to use their official service resources to verify the latest specs, parts numbers, and procedures that apply to the vehicle you're working on. Thanks again for making this video.

It was a 12mm bolt and was 8 inches long. The longer the bolt the better as it will have more threads to make sure you have 3/4 the thread inserted in the crank before force is a applied. /K&K

Just hammer it in for a little bit and insert the original bolt, push them in and take the old bolt and and put the new one on.

Great 💯

We do them all the time. Tools needed: Beside a socket big enough to pound the new seal on the timing cover its business as usual. Its simple to do with a small twist, this setup also use a dust seal (Looks like a fan) that spins with the balancer. Don't over torque the balance and jam the dust shield seal into the crank timing cover oil seal, there must be some end gap for heat expansion. We did not use a special tools on this seal setup. Ford was nice to us on seal service for the 4.0L V6. /K&K

@KNKRNR

6 жыл бұрын

Not sure what a timing cover aligner is, we don't use them because the engine already has aligning pins for the timing cover. As far as the timing cover crank oil seal I believed we use either a 3/4, 7/8 socket to drive the new seal in. The crankshaft oil seal does sit below the face of the timing cover. The dust shield that goes on the balancer, we will leave a couple of thousands end gap in between the dust shield and timing cover oil seal. Easiest way to set gap is simply to leave a small gap. In this order, remove and clean the timing cover, remove old oil seal and install new crank oil seal on the timing cover, bolt on timing cover and torque it to spec, then install the balance and set final gap for the dust shield when the balancer is almost torqued up. Once the balance is almost torqued up "always be checking" the final gap where the dust shield meets the oil seal. You won't be able to see much beside the dust shield. In this case we follow the dust shield in as we do the final torque of the balancer. In this video towards the end you will see the gap we left between dust shield and the timing cover crankshaft oil seal. If you follow the order listed here, you should have very little issue with alignment and fitment issues. /K&K

You can leave the timing cover on and try to replace the seal, but it can be rather difficult. Worst case try to remove the oil seal with cover on, if that don't work you can always pull the cover off later if needed. There are different types of seal pullers and seal drivers designed to remove & Install seals with parts in place like (timing covers) at Harbor freight and most auto part store.

You going need some smaller drill bits to start the Extractor hole and then you need a set of "EZ Outs" Screw bit Extractor with varies sizes to remove the broken bolt from that crankshaft if that head snapped off. Link below shows the types of "EZ Outs" at Lowe's you will need to get. This is not an easy process but we have found by drilling the broken bolt dead center and increase the drill bit size as needed till you can fit the smallest "EZ Out" in first works best. You may need to increase the size of the extractor bit till the bolt reverse out. Start with the smallest extractor bit first and work up till the bolt come back out. Also do not drill past or into the crankshaft! That crankshaft bolt hole is deep but better to leave wiggle room as they say then drill into that crankshaft. Drill the starter hole into the broken bolt about the 1/2 to 3/4 the length of the size "EZ Out" you plan to use first and no more then needed! Use a small piece of tape on the bit to set a stop point if needed. www.lowes.com/pd/KD-Tools-4-Piece-Spiral-Fluted-Screw-Extractor-Set/4731419?cm_mmc=SCE_PLA_ONLY-_-ToolsAndHardware-_-SosAtg-PowerTools-_-4731419:KD_Tools&CAWELAID=&kpid=4731419&CAGPSPN=pla&k_clickID=bad99ad5-c25b-467a-92dd-b2b929535b24&gclid=CjwKCAjwq57cBRBYEiwAdpx0vbwQYnH0nWtOX7_2rMkPGQXUMiwICO93FLHspEUgJ8tJ1E5XI2H-6hoCuwcQAvD_BwE As far as the replacement bolt goes I would suggest going to the Junkyard, Dealership, or Ebay.

Has anyone thought about just using a piece of threaded rod and a nut? Threads aren't particularly delicate if you pay attention to what you are doing and are patient. With a steel bolt going into threads of equivalent strength steel, you ONLY need the bolt's diameter worth the thread length for maximum strength. Threads beyond that do absolutely nothing to help you. That's why you will almost never find a nut that is thicker that the minor diameter of the threads within it.

We live in a very small town and that bolt I used was the only threaded bolt ACE hardware had that would fit the crank thread. If I could have found a fully threaded bolt instead I would have used it. Its much safer to keep the force on the outside of the balancer then rely on crank threads alone. I made sure I was 3/4 the way in with 13 turns of the grade 8 bolt before any force was applied to the crank treads, I stated that a few times in the video. Some people will disagree with this method, but it has worked well for me for over 20 years. /K&K

The 4.0L OHV is a great engine, but does have minor issues to work through like most brands often do. Its a little under powered but I have seen many make it 300,000 miles. Once the cooling system has a major problem (204,000 Miles) like this one did, you do run the risk of the transmission (470RW) losing first gear and codes PO730, PO731, PO733, PO734 become present. Loss of first gear or incorrect gear ration obtained. This problem is cause the ATF fluid not being cooled in an empty radiator and the transmission quickly overheats and hard parts brake. Keep the cooling system in good shape do normal maintenance and they can run for a very-very long time. /K&K

It is a skookum engine. The pushrod versions are a bit better, with the difference being the timing chain issues of the overhead cam version. It really sucks to have to deal with those timing chains since the engine *has* to come out, and by service procedure, one cylinder head needs to come off to remove a chain guide on the front of the engine, but aside from that, the engines don't have any problems. Valves don't go to pot, pistons don't break, they don't consume lots of oil, heads and blocks don't crack, head gaskets aren't much of a problem. You *can* get that timing chain guide replaced without head removal, but you have to be clever. I just got done with a timing chain job a couple of months ago. It went 208,xxx miles since 2006 (2005 model year) with *ZERO* engine repairs. A belt and spark plugs were the only things ever done to it engine-wise. Literally, *ZERO* repairs other than the chains. The chain repair was expensive and enough to condemn the rest of an otherwise good-shape vehicle, but I fixed it and its back on the road again.

No, 37 foot pounds sounds more like main barring bolts. For a harmonic balancer it would be well over 100 foot pounds of torque. 105 to 130, maybe more. Better check spec's!!!!!!
