  • I desperately need some advice on a 1983 AMC v8 timing chain
  • A friend brought his 1983 AMC jeep 360cid v8 engine over to me in several boxes and ask me to help reassemble it. He sent the engine out to a shop 6, months ago to get it rebuilt,all they did was disassemble it cook it out and never touched it again.I've done several engines but never one of these.So far with the help of a Haines manual I've got it mostly put back together.But I'm stumped on the timing chain, most engines you line up the dots on the crank gear and timing gears at 6 oclock and 12 oclock, but the manual seems to say that the crank gear dot goes on the bottom at 6 oclock but the cam gear dot goes at 3 oclock with 20 chain pins between the dots. I've looked all over the internet for information to find if this is correct or not. Are any of you guys familiar with these engines or know where I can find the information I need.HELP!!!!!!!!, God Bless, Beth and Allen.

  • I checked with my local Chrysler/Jeep mechanic and he said that Bruce Dorsi and I were right. Just to make sure he looked it up on the Chrysler/ Jeep computer and it agreed. Bottom shaft mark at 12 o'clock and top shaft mark at 6 o'clock. Hope this helps.

  • Thanks Carl, That confirms what I thought and Bruce also posted. I really appreciate every ones help on this, the owner insisted that the timing chain be installed at 6 oclock and 3 oclock. This will save me a lot of time although I would have turned the engine by hand while on the stand BEFORE I installed the timing cover. God Bless, Beth and Allen.

  • Check with a mom and pop engine rebuilder in your area and ask them, and or find a motors manual of that era and look in that. What auto zone info was conflicting. Y-block ford engine isn't timed quite the same, so don't go by that.

  • I'm almost positive that it is like Bruce Dorsi's diagram. I will check with my local Chrysler/Jeep dealer tomorrow. I have a good repertoire with him..

  • I believe the y-block timing was like what hane's manual stated. Maybe not the same as amc, but still not togeather like gm. You could probably check it out on the internet. O yes that was a ford 1954 and up v8.

  • VERY MUCH, appreciated. As I said in my other post this jeep is very special to my friend, it's been in his family since day one. It is super clean inside and out, very low mileage, but what did the engine in was the fact that the original family member (now deceased) only drove it a couple of miles a day and it never got up to operating temperature and he used cheep oil, so sludge built up and plugged everything up. God Bless, Beth and Allen.

  • If the links works, scroll down to 2 pics of timing gear marks for the 360 V8.

    I didn't read the text, but it may be what you are looking for.

  • I couldnt find it either but I can't imagine that the two timing marks shouldn't be facing directly across from each other. I.e. 6 o'clock (cam) and 12 o'clock (crank).

  • Re: Reply to Bruce and Stump Blasters
  • Thanks to both of you,1st, Bruce that is somewhat like what the Haines manual is showing,but as Stump Blasters is saying it totally goes against what is normal timing chain installation. But what you posted confirms what the manual is showing. Since I wasn't the one tearing engine down I don't have a visual image in my mind to refer to.I really want to get this right, my friend spent a lot of money on this that he really doesn't have, the Jeep is a family heirloom so it is special to him. I'll go ahead and install it that way and then turn it over by hand on the engine stand and check every thing. If it is wrong it is better to find it that way than after it is in the vehicle. If wrong in the vehicle it could bend push rods,break or bend valves and even break the tops of pistons. It will be next Wednesday before I can get back on it, I'll post back as what the outcome is. Thanks and God Bless, Beth and Allen.

  • Re: Reply to Bruce and Stump Blasters
  • The brain is tired as I have been working an early morning split shift routine this week. Normal returns soon. Just not today. Me? I would goggle or U-Tube the 360 timing chain for installation. Find an oil pump prime tool and pressurize the oil system before installation if possible. This should also help to get the hyd lifters up to snuff before installation. Chances are priming and rotating engine should be done at the same time. This gets everything working, lifters pumped up, etc, and gives you knowledge it will work before installing.
    Small block chev has donated a dist in the past for me with a stud welded to the top and the cam gear ground down. Connect a drill and have a spinning good time.
    The chev engine needs the lifter galley sealed so it will get pressurized.

  • See Diagrams AGAIN
  • If you look at the first of those diagrams for the 360 V8, you will see that the gears are installed with the dots opposite each other (12:00 & 6:00).

    The 2nd diagram illustrates how to VERIFY the installation is correct by rotating the crankshaft until the dots are in the position shown.

  • Re: See Diagrams AGAIN Reply to Bruce
  • Thank you my friend, That is exactly what I thought. But the owner insisted it be installed with the crank gear at 6 oclock and cam gear at 3 oclock. Thankfully I talked him in to letting me research it. That makes total sense that the 6 and 3 would be the way you would check to see if it was installed right.Thanks to all of my friends on here I knew that if there was any place to find the right info it would be on the good old nclub. God Bless, Beth and Allen.
