Hello All, It's been way too long that I have posted anything although I have looked in on The HAMB from time to time. I started a 265 Chevy build a long time ago and have finally put my mind to getting it done this year. I picked up a Fisher dampener up over the weekend for $50. (will load pics later when my phone lets me upload them!) I would like anybodies input on it. Seems to be in very good shape but I would like to know if there is a way to inspect it (or have it inspected) to make sure it is in good working order. I look forward to posting more and adding some parts for sale to the cl***ified ads.
neat! If you take pictures from an angle, both sides, we might could see stuff that might affect it's operation. Like groove in the hub, pulley wear, etc.
Here is one. Phone is really being a pain sending pics. I do hear a slight "click" sound inside when I rotate it.
Is it a solid hub? OR is there a layer of rubber in the middle? I like the graduation stamped on it. No need for a timing tape when setting TOTAL ADVANCE...... 6sally6
I took some Squirrel but my phone is still being a pain ! As soon as I can I will post them. Until then, this pic from the internet looks exactly the same just mine is bare aluminum like the front.
6sally6, I didn't see a layer of rubber in the middle but I will have to look real close. From what I can tell, it looks to bolt the from and rear aluminum face together with (2) steel "wafers" in between. I found a pic on the internet with (4) wafers and it said it was a 9 Lb. balancer. So I ***ume each wafer is a specific weight. and yes the timing marks are cool. It is marked in 360 degrees. It is even marked with a number as high as 90 degrees advanced ! Don't think i will be running my little 265 90 degrees advanced but you never know ! LOL !
We gonna 'cam-it-up......better breathing heads.....nice hi-rise intake with plenty of carburetion....free-flow headers & muff(optional) ??! If so..... you want to modify the ignition timing to make it more driveable and perform like it should. Jus-say'in..... 6sally6
Hey Squirrel, what are your thoughts after seeing the pics ? Let me know. I would appreciate your input.
Let me know what kind of pics I need to take and I will do my best. It seems to solid material other than that I hear slight click type noise like there is a small ball bearing or shot inside. Can these be taken apart to inspect the inside ?
Those Genuine Fisher balancers just do not like to have their picture taken. They tend to be a little shy and non photogenic at times. Keep working at it, bfalfa55.
Most balancers are either have a rubber element or contain silicone fluid. After a quick google search It looks like Fisher uses dry friction. I have never ever seen this style used by OEMs. Personally, i would not use this style, especialy second hand as it has a much greater potential to fail. You wont get to find this out until you crank breaks.
Umm, that would be a "Harmonic Damper". NOT...a harmonic balancer !! No counterweight...no "balancing" action. There is no external balancing going on with the dampers pictures above. To be a "balancer"...it has to..."balance". As with a small Chevy 400, or a Chevy 454. These have a counterweight that...helps balance that crank shaft. Mike
Both harmonic balancer and harmonic damper are terms commonly used for this device, along with crankshaft damper (mostly in europe). The term balancer is still a valid term as it balances torsional vibration harmonics.
I'm sure that's a fact in a high RPM situation but..... would it really be catastrophic in a street driven situation !? Not an argument just wonder'in........ considering there are some guys (race engines that don't even run one) 6sally6
Absolutley it would. By far the best parts to use are the ones developed by an OEM for the car manufacturer. I was an applications engineer for a european crankshaft damper manufacturer in the late 80s.
I put a Fisher on my Slant. It’s a super nice piece. That click you’re hearing is indeed some “shot”. I guess it’s just part of what they used to absorb vibration. Mine made that noise brand new. My engine runs very smooth and I’ve got no complaints/issues so far. Only thing I had to deal with was spacing the pullies out a bit to meet up with the crank pulley. I don’t see anything concerning with yours. That’s just some surface rust and a couple scuffs. Just make sure the hub bolts are torqued and throw it on there. Best of luck!
Thanks ! That's what I was hoping to hear. All the research I did, not one person said these were bad. As a matter of fact, many swore by them being a great piece. My little 265 will be cranked up to just about 7,000 RPM with this build so I don't trust a factory dampener and I sure don't trust the tiny 60+ year old factory one on it now ! As part of the engine machine work, somebody already tapped the nose of the crank for a bolt. These early engines didn't have them, they just pressed the dampener on. I figured that click was some type of shot as part of the design. I see these for sale from $250 and up. I think I got a score at $50. It's Nostalgic enough for this old engine !
I have to agree with you Mike. I am using the wrong term as both of these have been used interchangeable and are not exactly correct. I know my engine is not externally balanced, so this damper should work great for what I am building. I will call this a "damper" from now on just like I call it an "engine" and not a "motor" because those are two words that are interchanged and they are not actually correct replacements for the other, calling an engine a motor is really kind of a slang term.
Yup mine sees 5-6k pretty regularly and the Fisher is the last thing on my mind. The only that shakes are the tires. Hey if it aint nostalgic enough for you, paint it black. Glad you’re getting moving on the build now. I’ve really enjoyed reading all the planning.
