http://s69.photobucket.com/albums/i75/He4l2t/?action=view¤t=IMG_0360.jpgA harmonic balancer installer tool did not work out because i could not grab the nut with my wrench because it was to deep into the balancer. I also tried to use the balancer bolt to press the balancer on but even with a lot of force and holding the crank from spinning the balancer can be pulled off by hand. any ideas would be much apreciated.
------------------------------------
 I'm a bit confused because it sounds like two different problems and I wasn't sure what was what in the picture. However I've done my share of timing covers and balancer R & Rs so I'll throw out some things which come to mind. If the balancer isn't sitting far enough on the nose of the crank it's possible the oil slinger could be on backwards. I've never had a balancer that could be pulled off by hand unless it was very close to the edge. If nothing was done in the way of sanding or filing (gulp) check for a crack where the balancer goes over the crank. Something isn't right and you have to make sure the balancer is okay. Anyone who has ever seen a balancer let go when the engine is running will tell you it's like a bomb going off under the hood and can do about as much damage. | Flick01@... flick12003 | Jun 18, 2009 3:10 am |
| sorry i did not explain the picture, that is inside of the balancer while it is on the crank. That is as far as it goes whether it is slid on by hand or torqued down hard. it will not sit flush with the crank no matter what i do. Good suggestion about the oil slinger but i believe it is on correctly with the flat side facing the cover not the chain. here is a picture of my balancer  ://s69.photobucket.com/albums/i75/He4l2t/?action=view¤t=IMG_0346.jpgSomeone told me to try a sleeve to take up the slack or maybe an impact wrench to get it on there. | ultimaweaponzero2000 ultimaweapon... | Jun 18, 2009 8:33 pm |
| First question: There seems to be a lot of excess grease in there. Second: Are you aligning the Woodruff key with the slot in the damper? | Walt Boeninger walt@... | Jun 18, 2009 4:16 am |
| Hi, That is just a little white grease i used for lubrication. Yes i lined up the balancer with the crank key. It slides all the way into that exact position in the first picture. From that position the balancer will not move anymore, some one suggested using an impact wrench from that point but im a little worried, i dont want to put to much force that fast on it. here is a picture of my balancer maybe it needs replacing the rubber looks a little old | ultimaweaponzero2000 ultimaweapon... | Jun 18, 2009 8:25 pm |
| The looseness aside, if the balancer was all the way down before you took it apart and now it doesn't go down as far, and you didn't replace the timing gears (possible wrong bottom gear in that case) I don't see how it can be anything else except the slinger or something down in that area. For the cost of the gasket and some labor I would remove the cover and try putting the balancer on when everything is exposed. | Flick01@... flick12003 | Jun 18, 2009 9:03 pm |
| Alright flick ill take everything off and slide the balancer on to see if with nothing on, the inner shaft can line up with the crank end.Its just about a cm from being aligned with the crank so what could hold it that small amount of space. p.s. which way should the flat end of the oil slinger face? | ultimaweaponzero2000 ultimaweapon... | Jun 19, 2009 7:02 pm |
| hello flick its been a few days because i have been working so much. I took the timing cover off to get a better look at things and the slinger is on correctly. I also noticed the lower gear slides a little bit forward and backward on the crank. That being said with the slinger on and the gear all the way back the harmonic balancer slides all the way back with no effort. Pressed hammered or any other method it looks like it cannot go farther. Because it can be installed by hand does that mean the balancer is worn out and is to loose? Or, i dont even want to think about this,could that also mean my crank shaft end has been worn out and that is the cause of the looseness? | ultimaweaponzero2000 ultimaweapon... | Jun 24, 2009 11:58 pm |
| P.S. I know this is only a remote possibility, but I once locked up a camshaft by putting a half a pinky tip of grease in the wrong place. (yes, I really did) There's an outside chance the white grease you put on the crank nose got pushed back into the oil slinger, got trapped in the little concave area, and is preventing the balancer from going all the way down. (We use grease to remove pilot bearings, right? Hydraulics is some powerful stuff!) | Flick01@... flick12003 | Jun 18, 2009 9:13 pm |
| Hence my comment on the amount of grease..... grease doesn't compress!... | Walt Boeninger walt@... | Jun 18, 2009 11:37 pm |
| Here is the obvious question. Checked for burrs on the crank or inside of the balancer? I am assuming this came off of the same motor.... Last thing you want to do is to force it on. It will take a bit of pressure, (enough to require a puller to remove it) but not so much that you have to apply major torque to it. Mahalo!! Jim Ohrt | Jim Ohrt jpohrt | Jun 18, 2009 9:19 pm |
| The small concave area at the bottom of the slinger should be touching the bottom timing gear. If it is reversed, the larger diameter will rub against the chain. The oil slinger essentially keeps oil from splashing up against the seal in the timing cover. If left out, the chain will still receive oil but there may be a leak from the seal because too much oil is being thrown against it. | Flick01@... flick12003 | Jun 19, 2009 8:13 pm |
| My first instinct is to think there is a crack in the balancer, therefore making the hole larger than it should be. I am doubtful the crank has worn as it is made to take the force of the reciprocating engine parts which moves the vehicle. If possible, see if you can get a cheap used balancer from a junkyard (or friend, or another source) to compare the fit. (I have an old one I can send you) I think the others will agree, it should not slide on by hand. | Flick01@... flick12003 | Jun 25, 2009 12:07 am |
| I have a good friend with a replica GT350 with a 302.. The engine builder erred in assembly by using a slightly too long of a bolt to secure the damper.... The bolt actually bottomed in the crank and did not keep the damper from moving..... after several years, maybe 10(!), now the damper slides onto the crank *really* easy..... at least it has the right length bolt now..... we tested the damper on a spare crank and it fits snug leading us to conclude the snout of the crank is slightly worn from the damper "walking" .... hard to believe.... he's not planning on doing anything about and it's been several years since we discovered the wrong bolt.... he noticed it because the pulleys were no longer aligned YMMV | Walt Boeninger walt@... | Jun 25, 2009 12:35 am |
| I know the bold was not the only thing holding it on becasue i had to use a puller to get the balancer off and i had been driving it for about 2 years prior to taking it off, before that it was parked for about 8 years. But is like now that it was pulled off with a puller the tension is gone and it just slides back in now. | ultimaweaponzero2000 ultimaweapon... | Jun 25, 2009 3:36 pm |
| I would have to believe that a balancer that does not fit properly is not going to effectively do the job it was designed to do, and that could lead to failure. Take cover when that goes. Phil | Phil Snyder phils3888 | Jun 25, 2009 8:35 pm |
Thank you flick but that won't be necessary, I live in Dallas and I wouldn't want you to pay shipping for that. I think I will order a new one its only about 60$ and take a couple of days to get here. Besides, I think it needs to be replaced anyhow the rubber around it is all torn up and uneven. Strange though, that a puller was used to get it off and now the tension is all gone and it just slides back on. | ultimaweaponzero2000 ultimaweapon... | Jun 25, 2009 3:46 pm |
| If it's the original and as you said, the rubber is starting to dry rot then yeah, a new one would be advisable. Not only can the dry rubber cause the balancer to come apart but if the top ring slips your ignition timing will be off as that's where the timing marks are located. I just rebuilt my engine (it's still sitting on the floor..... to hot in the garage right now to work) and I bought a one piece dampener from a speed shop that's a beautiful piece of work. It looks wider than my stock balancer, resembles a hipo unit but everything lined up when assembled. I don't recall the price but it wasn't expensive enough to change blood pressure so perhaps you'd want to look into something like that before you place your order. I'd still like to know why your original balancer too the 'normal' amount of force to remove and yet went on by hand and didn't seem to sit all the way down when the cover was on. Please let us know if you should find the answer. | Flick01@... flick12003 |
