06SubLegTx Posted May 6, 2017 Share Posted May 6, 2017 Hello, I have a few questions. 1. Does anyone on this site ever installed one of these on there cars? 2. Do they work? Could you see or feel the difference? 3. Is there a secret to getting in on without causing blunt trauma to the balancer? FYI, I have read there return policy and they say treat this like it a new born baby. 4. Where did you get it from and where you happy with them? How 5. I have not tried to install mine. I want to get what I paid for, if it will fit properly. See Below I purchased mine from THMotorsports online. When I received it, I took it from the box immediately noticed that it look used, I have called them twice now, and I am getting the run around. They offered $50.00 off if I would keep it. I told them I want what I paid for a NEW one, not scratched or anything. Just send me a new one.... This is what I recieved, thoughts? Link to comment Share on other sites More sharing options...
Max Capacity Posted May 6, 2017 Share Posted May 6, 2017 The ID looks like it has not been installed, looks like some one pushed it around on the work bench, that's where the scratches came from. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

I disagree, you can clearly see damage where somebody tried and failed to install it. A crank pulley does not need to be hammered on; it should slide on easily. This pre-failed aftermarket part is setting off all my alarms. What problem are you trying to solve by installing it? Does it weigh the same as a stock pulley? If not, it may cause problems. If you do manage to cram it on, how will you get it off? That last question is critical in my opinion. Link to comment Share on other sites More sharing options...
snm95ls Posted May 6, 2017 Share Posted May 6, 2017 Dampers have been press fit on many engines for the last 80 years. Installation and removal is not rocket science. I agree with Max. They can be installed with a tool like this: https://mobiledistributorsupply.com/harmonic-balancer-installer-1.html?gclid=Cj0KEQjw6LXIBRCUqIjXmdKBxZUBEiQA_f50Pg7mju995MW-hpT8YTMjz0eYCwUDUaVYJ9WoeBxvizsaAs-78P8HAQ# Yes, they work. No you won't likely "feel" any difference. Good luck with getting THMotorsports to take it back because of cosemtic damage that does not affect the part's functionality.

relative4 Posted May 6, 2017 Share Posted May 6, 2017 Dampers have been press fit on many engines for the last 80 years. Not these engines. You got a plan for fitting that tool between the engine and the radiator (and condenser)? Link to comment Share on other sites More sharing options...
snm95ls Posted May 6, 2017 Share Posted May 6, 2017 Not these engines. You got a plan for fitting that tool between the engine and the radiator (and condenser)? The OEM dampers/pullies on Honda engines as a general rule aren't press fit either, but the Fluidamper for them is and I am pretty damn sure that the ATI damper is as well. I hope you aren't under the illusion that the factory pulley is not press fit for serviceability because I can assure that is probably just about the last consideration. There are many, many more factors that come into play in the engineering and design of automobiles, and serviceability is usually way down on that list. I am going to ask you a serious question without the intention of starting an internet pissing contest, but how many different vehicles have you worked on in a professional environment? I ask because it is not uncommon to have to disassemble nearby sections of a vehicle in order to perform a service. Hell, it is all a moot point anyway because according to Subaru lore, there is no need to have a damper on the crankshaft at all. Link to comment Share on other sites More sharing options...

I see that white powder looking stuff as just dust not a scuff where where it was slid onto a crank. I think there would be more linear marks on the ID from where the crank was. These dampers should slide on without much effort, the bolt and washer hold it on and the woodruff key. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

apexi Posted May 6, 2017 Share Posted May 6, 2017 Definitely looks used to me, or like someone attempted to push it on without much luck. Looks like they also stuck something in the keyway and nicked the edge. Link to comment Share on other sites More sharing options...

pseank Posted May 8, 2017 Share Posted May 8, 2017 I do not think it was installed. I have never used one. I would send it back for no other reason than the scratches. Poor indeed Sent from my XT1254 using Tapatalk Link to comment Share on other sites More sharing options...
Volta55 Posted May 8, 2017 Share Posted May 8, 2017 I dont think it was installed there is no damage on the chamfers from someone trying to wiggle/ press it on scratches are just from poor handling at the shop Link to comment Share on other sites More sharing options...
HeyLoad Posted May 8, 2017 Share Posted May 8, 2017 I put one on my car. It went on easily, just like the stocker. It is about the same weight as a stock pulley but balances a broader range of harmonic vibration. I put one on because I replaced all of the valvetrain with the exception of the cams and buckets. I would recommend it if you are changing the parts in the top or bottom end from stock. Link to comment Share on other sites More sharing options...
06SubLegTx Posted May 9, 2017 Author Share Posted May 9, 2017 Thanks, I will keep it in mind. I sent it back today. If I get a GT later on, I will get one... Link to comment Share on other sites More sharing options...
Enlight Posted September 3, 2017 Share Posted September 3, 2017 I've been looking into getting a Fluidamper to replace the Perrin that my car came with and came across this video. This engine builder says that boiling the damper hub to above 200 degrees and putting on a dab of oil will help to get it on more easily. Relevant portion is at 4:21.
