I have the 765LT on my 720. So far zero issues and the ride dynamic has changed, especially in sport mode.
Was yours reprogrammed?
@@McMedics absolutely. Was in talks with you guys about having your combat change then out. At that time we both learned about McLaren replacing the 720s ones with the larger 765LT ones. McLaren Houston did the work and had the car reprogrammed.
Ah yes I remember. I am a little curious how it rides without reprogramming but I also don't want to cause an unnecessary problem finding out.
YOU ARE THE BEST
THANK EMF
Excellent video. A couple of things come to mind: the first two older examples obviously look like they probably could never be rebuilt. Which is a shame. Although if someone could figure out how to do that… that would be something. If there were a way to take the last one and put an adapter on it and make it so that you can mount it to the older cars that might also be something. That should not be “all that“ difficult. And I am going to bet that if you were to dig into the last one ….that you could rebuild it.
The physical dimensions make that not a thing. There is something else you don't know though, the software update. When you fit 765's to a 720 there is a software calibration to do as well. It's not as clean cut as you'd think. McLaren keeps as few part numbers as possible. If there was a way to adapt a new part to the older model, McLaren would sell it.
Thanks for posting the video. You've mentioned the car would need to be reprogrammed if you want to upgrade the 720s collector to the 765lt collector. What exactly does the dealer need to know? My local mechanic said they'd happily do the work, but they don't have the programming tool. Also, mine is on springs; not sure how that would affect it. Thanks!
You have to have MDS to program it, a dealer would need to know they've been changed to 765 style. The springs you should put back to factory regardless.
It is gas filled inside with a piston instead of diaphragm.. concept is same as DQ200 accumulator
That is correct.
I was debating on the possibility of being nitrogen or a spring. Maybe one day I'll come across a failed one I can open up
Are you putting the new 765 versions on your 720S????
I already did. It's not just a direct swap and call it done though, there is a software update that needs done.
@@McMedics Please make a video on the whole process including the software update. I talked to John Thron at SEMA this year. He told me once the 720S accumulators fail and are replaced with the McLaren updated ones they do not seem to fail. He stated that he has never had to replace them after being replaced after the first failure.
@@orangegrowers I'm not doing any accumulator videos because it can be a dangerous activity that can get people injured and I don't want to be a part of that. The software update requires MDS, so if you don't have it, it won't do you any good. It's too early to say they won't fail because they've been out for 2 years. Even the old style last longer than 2 years. I can tell you doing 765's takes over twice the time and requires 2 people also.
@@McMedics I understand why you will not encourage people to do their own accumulators. I was an aircraft mechanic for 37 years and replaced many accumulators. I get it. Thanks for the videos.
Think these fit on a 650S?
They do not.
