In this video we install the timing drive system in the engine. Not at all a trivial process, but with patience, it's very doable.

Just wanted to thank you again Trey for your in depth videos on this 3.7l. I can't tell you how many times i watched them and how much they've helped me on my rebuild! I've never rebuilt an engine before this and your videos plus a lot of in depth reading gave me the knowledge and confidence to do this and made it go do smoothly. Thank you sir!

Trey, your presentations are outstanding. You should be teaching at a University or College. You give explanations as to what each part is, what it does, where it goes, and you give caveats as needed. You add NO FLUFF to your presentations, and your video views are excellent. Using your multi-part presentation, my Daughter... a Nursing student, and myself, an old AC repair guy, are rebuilding her 08 Jeep 3.7 Liberty after head failure from over heating. Neither of us have done this before... I do all our vehicle maintenances but never something this complex. With YOUR videos along with those of Issac Moreno and Martinbuilt, we are rebuilding her vehicle. THANK YOU for the time you have taken to create this EXCELLENT step-by-step series...

Changed out sensor still flickers, looks like i’ll have to change the oil pump again. But thanks for all the great info especially on the timing.

@TreyClanton3 жыл бұрын
aaron campbell The tensioners should have come with pins installed in them to keep them compressed. You should pull those pins. In my experience once those pins are removed, the tensioners tighten up by themselves. When there is oil pressure present, they will tighten up more, but they shouldn’t be slack after they are installed. You might try to pull the tensioners toward the tighter position. They might just need some encouragement.

Very observative. The last time I installed the idler, the chain was off by one tooth, but it was off on both gears, so the engine was in time. I did realigned the chain even though it did not affect the timing. The key to success with the idler chain is that your dots on the gears be right. The crank gear mark should be at 6 o'clock and the idler gear be at 12 o'clock. Thanks for noticing.

@TreyClanton7 жыл бұрын
Kro- Man I'm pretty certain you can, but if you have access to an engine lift and engine stand, you might consider pulling it. The challenge is that with overhead cams, you will likely have to pull the timing system. You might be able to figure out a way to wedge the chains and keep them from dropping, but the tensioners will likely give you fits. If the truck is going to be a long term driver, it might be worth just rebuilding it. Either way you go, I wish you the best results!

Trey Clanton. I understand. It sure seems like a pain to get to the back side to loosen from the tranny.

Is your concern that we might miss something on the bottom end like you found in this video series?

@TreyClanton6 жыл бұрын
Forgive me. I'm a bit confused. If the engine is at TDC and you line up the cam sprockets on the head (V6 pointing up), both valves on #1 cylinder should be closed. (compression stroke).
@MMGJ106 жыл бұрын
Do basically it was a dumb question lol. I thought it was. So If the #1 cylinder is at tdc and the "v6" on each cam shaft is at the top then it's timed correctly. Each revolution of the crank only turns the camshaft one half of the way?

Hello Chris. I know that feeling. I had a little trouble getting this one to begin to move. Once it did move, it wasn't too bad though. I had to carefully use a pry bar behind the gear to get it to break free. I had to tap on the pry bar, but do it very carefully! I don't remember if there is room for a puller behind the gear, but that might also yield results.

Hi Trey, when you say you confirmed TDC, how do you determine that? I know that it means first piston is on the very top, but can the crank be 180 degrees off? Or can it be mistakenly put on the exhaust stroke? Just wondering how you confirmed. Thanks for any input.
@TreyClanton3 жыл бұрын
Ethan Reddick For this timing system, TDC is self resolving. If you place the marks on all of the gears, in the correct orientation, the engine is in time. This includes the mark on the crank gear, the mark on the balance shaft gear, and the two gears on the cam shafts. There is no need to check piston location.
