Damper Dudes is great. I held off for awhile thinking it'd take a month to get back, but I shipped my balancer out on Friday and got it back by the next Friday.
It's hard information to find, even on the old interwebs, but the 260 did indeed have a different imbalance than 289s. From the January/February 2008 Fairlaner (Fairlane club of America) magazine article titled Small Block V8 balancing: 62 to 63 221 had a 23.1 imbalance. 62 to 63 260 had a 24.5 imbalance. 64 260 had a 26.2 imbalance. 63 to 68 289 had a 28.2 imbalance. So while you can run the 28.2 imbalance damper on a '64 260, it won't run quite as smooth as it will with the matched 26.2 damper. Best to get the Damper Dudes to rebuild the original damper. Everyone likes a balanced engine.
@2 decades ago a Dyno test was done back to back comparing dampers on. SBC.... There was major power differences. As I recall the best one was a factory 8+ inch diameter. I'd like to see somebody compare factory dampers with aftermarkets... Like the rattler, etc.
I would like to find someone who can figure out why a brand harmonic balancer does the same thing that the old one did move away from the motor toward the radiator and then go back in place depending on rpm
Hey Jeff Real good advice about replacing that harmonic balancer but on camera it looks like you will have pulley alignment issues with that new one. Hard to tell without measuring though. Was iit just an optical illlusion? Thanks keep up the good work.
does a bad harmonic balancer cause motor vibration? My engine has a vibration sitting in park at different rpm's. It smooths out also at different rpm's. The vibration can be felt in the steering wheel and seen like the ash tray shaking. It's a 1973 F100 with a 1980 302.
I recently had a 350 sec built, I was just looking at it and realized that the harmonic balancer looks too small for the motor because the outside circumference is about an inch and a quarter away from the timing gauge pointer, what size harmonic balancer should I have on this thing… help!
Great video, love your context. I have a 65 mustang I just bought.. vibrates insane at all times when I press the excelerator. In park, drive, at all times when i press the gas the car is vibrating like crazy. Any ideas? Thinking it could be the harmonic balancer but I’m not sure? Thanks!
That is most likely an engine vibration. Check the balancer, then check to make sure that your engine is firing on all cylinders. Contact me directly and we can whittle on it together. Jford@autorestomod.com
hey bro hope you fixued your issue , i have same vibration in my dodge charger 400 , same as yours vibrate in drive and in neutral when i press the gas . did you figure it out ?
thanks for the video ,need help please. am having vibrations in my 73 Charger 4 speeds (originally automatic car) , vibrates in drive and in neutral if i raise the RPM ( if even goes more bad when i raise the RPM while standing still ) did my driveshaft , wheels , alignment and the engine is running fine ( appart from running rich ). few told it that because i don't have a pilot bushing on my flywheel ( judging by an old picture of my engine before installing it ) could this be my harmonic balancer or something else ? thanks in advance love the channel
@@AutoRestoMod is it possible to get an intermittent vibration from a bad harmonic balancer? I have an intermittent vibration that is coming from the engine. I camt isolate it to any specific running conditions. While driving down the road and the vibration starts I can throw trans in neutral. Let off the throttle. Rpm's slow, so does the vibration. Rev engine up vibration speefs up. Put trans back in gear. And drive. The vibration comes and goes randomly. It doesn't coincide with acceleration, braking, cruising or, idling. Ive replaced plugs, wires, cap and rotor. No change in the issue. Ive wondered if the egr could cause this issue but I dont know if its possible. And it seems to be ok. The vacuum lines all seem to be good. The carb functions well and has been recently adjusted properly. When the vibration isnt present the engine runs perfectly. It runs so smooth when running down the road you cant even feel it running. This has been very frustrating. Any help would be highly appreciated and Id be very thankful. Any ideas ?
@@whatyoumakeofit6635 hope you found out your issue , i have the same problem now in my dodge charger 400 4 speeds ( some told me flywheel , others pilot bearings and other harmonic balancer ) drive shaft and wheels are good engine is running good. if you found out your problem please tell me thanks in advance
I wanted to ask something being that this is about dampers. When you have a engine built and its balanced to lets say 50oz and lets say 5 years down the road your damper goes bad, can you swap it for a new one even though the new one wasn't balanced with that engine? I'm assuming you can or they wouldn't sell dampers, i mean Ive done it many times and the engine ran beautifully with zero vibrations but i was just wondering how that works? I'm guessing if when the engine is built if the builder messed with the damper or the flexplate then one would be screwed cause the crank and whatever piece was altered are now married together. Ive always wondered about that, I'm guessing its just like replacing a driveshaft? a lot of folks say "be careful,mark your driveshaft before you work on your car!!" well... what if i wanna get a super duper million dollar carbon fiber driveshaft, then what??? i have no reference point since that driveshaft would be new, thank you for your input, i like asking weird questions from time to time.
Hey guys, I have another question about my 63 Galaxie... again :) Can a bad harmonic balancer cause vibration/harmonics while driving? I have a weird vibration between 40 and 60 MPH that I have been chasing for a while. I have had the tires balanced by 3 different shops because I thought it HAD to be the tires. Now I am convinced it is in the drive train somewhere. The engine is a bit old and the harmonic balancer is certainly questionable. A new harmonic balancer is only 100 bucks-ish but if it wouldn't cause this problem, I could put that 100 bucks towards something else. What do you think? Thanks again for the advice and the great content!!! Love your show!!!
Frank Rizzo: Nice name there jerky! =) Uncle Freddy died??? As for your question, it could be a driveshaft out of balance. I think you can take the driveshaft to a driveline shop and get the balance of the shaft and the u-joints checked out. Or a belt in one of the tires... which sounds odd, but it happens. If tires are the problem you can diagnose front tire problems as a vibration felt in the steering wheel and rear tire problems as a vibration felt in the seat. Doing a tire rotation will help you further diagnose this too. If you swap the fronts to the rears and the vibration moves, you are on the right path. Hope that helps you out brother.
@@fwh79FOXR6 You killed uncle Freddy????!?!?! Hey there, just saw your reply today. I'm still chasing the vibration. I drive the car about once a month. So its not a huge deal. I think it may just be crappy tires
@@rob69270 I had a vibration in the drive line when accelerating hard in my Mustang. I changed the gear oil in the rear axle and that almost completely eliminated the vibration. I was not expecting that to happen. I think my problem is being caused by the lowering springs I installed. The lower ride height changes the pinion angle of the rear axle, which can cause a vibration. Cars are strange... sometimes when you finally solve a problem, you can't believe what the actually cause of it was.
Hey Guys, Please HELP! I just had a new remanufactured engine installed at no small price and I'm worried the mechanic damaged the harmonic balancer or something else on install. I'm just getting started on mechanics and maybe this guy thinks he can give me the run around, I don't know but I can't seem to get a straight answer. Wouldn't be so bad if I didn't spend my grocery money on this engine. In any case the vibration in the engine is WORSE now than when there was an old engine and an old harmonic balancer. Also I can see that crankshaft pulley has a wobble even though the harmonic balancer is BRAND NEW! My questions: Did he damage/bend something, what could be damaged, should I get it fixed, could this damage the crankshaft? If you can help I'll be forever grateful. Thanks!
I would clean the threads up on the bolt then push the balancer on the crank and start the bolt it should self align as long as the big washer is on the bolt.
I've got a LS swapped foxbody that I put a BTR stg 3 cam into, 3500stall converter, th400. At 2500+ rpm, I get a vibration that pulses. It does this in park and at any speed. 2400RPM, it's fine but as soon as it hits 2500RPM it starts. I'm replacing the balancer this weekend in hopes this fixes the issue. Just wondering if anyone thinks this is the issue?
You have something in there that is causing a balance issue since the LS is internally balanced. Or it could be a converter balance issue too as this spins with the engine even at idle.
Thanks guy’s, this is a timeless classic. My front seal is leaking and this is helping with my prep. 👍
Glad to be of service
Again, fun to see Cam get more comfortable in front of the camera. Nice, clear presentation.
Damper Dudes is great. I held off for awhile thinking it'd take a month to get back, but I shipped my balancer out on Friday and got it back by the next Friday.
Damper Dudes rock!!! I can attest to that.
Agreed it's no good. Looked like the one I just replaced, the rubber was all squished out unevenly. Couldn't believe the difference a new one made.
really important information!
well done 🌻
It's hard information to find, even on the old interwebs, but the 260 did indeed have a different imbalance than 289s.

62 to 63 260 had a 24.5 imbalance.
64 260 had a 26.2 imbalance.
63 to 68 289 had a 28.2 imbalance.
So while you can run the 28.2 imbalance damper on a '64 260, it won't run quite as smooth as it will with the matched 26.2 damper. Best to get the Damper Dudes to rebuild the original damper. Everyone likes a balanced engine.
Well... that is pretty confusing! Lots of different imbalance going on there. Nice post, i'm sure it will help a few people out!

If there is no pilot bushing that needs to be fixed or you will be rebuilding the transmission.
Other than the risk of separation, what problems could the dried out and cracked rubber cause?
vibration issues.

Many cars have NVH weights on tail shafts, drive shafts, etc
My restomod Ford liked a junkyard trans weight under the tailshaft.

We'd definitely have him look at it. If you paid the man, the man should check out the engine.
Any special tools required to put the new one back in?
I would clean the threads up on the bolt then push the balancer on the crank and start the bolt it should self align as long as the big washer is on the bolt.
Heat the new one up in your oven to 250 degrees and it will slide on like butter
To set timing do I look in the round hole of the timing pointer or the sharp edge?
Use the sharp edge.

3 bolt pulley? *looks at the 4 bolts on his Ford small block pulley* Huh....
Early 1962 to 1968 cars came with three bolt harmonic balance pulleys. in 1969 Ford switched to four bolts.
No impact sockets and no safety glasses? Suit yourself....
Yes. Yes we will.
That's an attention getter....
The downside was the Chinese tool worked and you still complain and complain about the cheap tools even it worked ( classic American)
This guy could use a diet balancer.
You could use a filter.
