TSB for Secondary Cam Chain Tensioner

[Houston Kid]

Check out the video here. Post 96.
This is why many feel it's a builder problem and not a part problem and if the builder activated one side they in all likelihood activated both.

I was doing some research this morning and apparently they are activated by the builder. I saw this in an article that stated some were not correctly activated during assembly. I can not tell you if this is accurate info or not. But it is the latest I have seen. BTW, checked mine and you can clearly see it is activated. Additionally, I did not receive a Ford Pass Notification and at the Recall website it did say my car was not affected.

Interesting about pushing down on the chain/tensioner to activate it. I tried pushing down on mine, which isn't activated, but It didn't move. I wasn't applying great pressure because I didn't know how much pressure is needed. I'll try again using more pressure next time.
But even if I do get it activated, how do I know if the driver's side isn't activated? You can't access that one like on the passenger side. And how do I know if any damage was done to the chain besides?
Remember my car isn't on the list, so I need a tech to see that it's not activated, and then for them to make a case to Ford to somehow authorize repairs

Very interesting, so the builder is required to activate it...

No dog in the hunt here, was just interested to see what this was all about. If it were me, I would not try to activate it myself. If you are successful, Ford will claim it was always activated and you may have any claims related to any damage denied. Especially since it is not on the list.

Which article did you see, do you happen to have a link?

Hopefully it is in fact a build process issue, and thus logically if one is activated then it is more likely that the other one also is activated.

It shouldn't be. These parts are fairly dummy proof.



Article is misinterpreting the TSB. Here's the actual language:

No focus on the actual builder. It's a faulty part. If you look deeper into the TSB, the first thing they recommend doing is replacing the tensioner. It's definitely a faulty part, not a poorly installed part.

It could be faulty parts but the builder activates during engine build so it seems that the builder should have found the issue during the build.

Have they changed the part number? Mine did not need to be activated when I installed them during my engine build.

Also, that compression would likely happen naturally under a running engine if it was forgotten since the chain moves around a good bit. If you rotate the engine over, you’ll see the secondary chain move up and down with the tensioner a decent amount.

Perhaps the secondary chain tensioner was already activated prior to your install? Accidentally or prematurely?

But no guarantee it is.

I was thinking the same thing, I have an appointment in the morning. Anyone here have experience with Serramonte Ford? I never take my cars to the dealer, I try to do all the PM myself.

For some reason i assumed you were going to tow it your self on a trailer.

Besides seeing that the shaft is not extended, my chain never did look taunt, or have that slight tri-oval look about it as it looks in the video. It actually looked somewhat slack

Did your car ever have trouble starting or rough idle?

Never an issue starting, no rough idling. As stated in one of my prior post, I would catch a little blip at a red light, this was very rarely, it typically surprised me. Chalked this up to maybe being a FPC.

I have noticed the same blip.
