    Timing chain

    Well tomorrow i'm going to be putting a new water pump in, getting the smog pump shit out, painting the valve covers and putting on new gaskets.I need a new timing chain also, mine has a lot of slack since i think it might be stock (205k miles). I have heard from some people that it is a PITA to replace if you havent done it before, and others say it is very simple. I'm willing to spend time and money for parts, but i dont want to mess anything up that i am not going to know how to fix. Specifically, does the timing need set after the new chain and gears are on, or do you just line up the dots on the gears and go? Besides a harmonic balancer puller, is there any special tools required? And what brand of gears and a double roller chain do you suggest that they would carry at napa, schucks, or autozone? I dont need anything too fancy, just reliable. Any other small parts or things i should remember to get, or any other suggestions before i try this out? Feel free to state the obvious, i really dont want to forget anything. I am going to take apart the timing chain stuff off a car at the u-pull it place here first as a bit of a learning experience before i try it on my car. I'l post pics assuming all goes well, thanks in advance for the help.

    I don't know much about timing chains, so take pics even if all hell breaks loose!

      Replaceing the timing chain is relatively easy, but getting to it is rather involved.
      Most of the accessories have to come off the front of the motor. once that is done, you need special tool to pull the Harmonic balancer off. also be carefull of the long bolts that hold the water pump and timing cover on, they are notorious for breaking in the block because they rust/corrode over time.

        Well its a good thing i tried taking apart the car at the junkyard first, i ran into a problem. I need to get off what i think is the crank bolt (in the picture below) but i dont have a socket big enough. Is it a 15/16"? Once i do have the socket will i be able to get it off with a wrench and a big pipe, or will it be on there really good? Once i do get that bolt out, is it just the harmonic balancer left, then i'm to the timing chain?

          yeah, you need a 15/16" socket.
          you also need a special tool to pull the balancer off.

          once the balancer is off you will need to take the bolts off for the timing cover. Remember there are 4 bolts in the oil pan that go into the timing cover from the bottom.

            you also will need to somehow keep the pulley/crankshaft from tunring while you try to remove the bolt.

              This is exactly where i'm stuck, any suggestions on keeping it from turning?

                Ok, now i got it to stop turning but i just break the wrench. Besides an impact gun or a socket wrench what is there to get it off?

                  Well i'm finally done for tonight...or i guess this morning... i started at 9AM saturday and its now 4:45 A.M. sunday. I got the crank bolt off, the balancer, most of the smog stuff, got on the new timing chain and everything else is back on except 1 hose, both belts, the fan, and the air cleaner assembly. Then fill up the coolant, and hopefully i did everything right and it will work fine. There was about an inch of slack in the old chain, almost enough to take the chain off while still on the gears. The new one is nice and snug.

                      Good deal. I was going to suggest a breaker bar and a nice long pipe to get the crank bolt out, but I see you must have figured that out.

                        I worked on it another four hours this morning and finished. Amazingly, everything works fine. When i started her up i figured i would hear some loud metal breaking sounds followed by plumes of smoke, due to the fact that i have never done any engine work at all besides a valve cover gasket... hell i've never even changed my oil before. I guess replacing a timing chain is a good way to learn some stuff though. Everything i have ever done to that car i have learned from reading everything on this site, if i never found the site i dont know what the hell i would do... thanks everyone!

                        I would say the hardest part about this process was not the timing chain, or harmonic balancer, or even the crank bolt, but just some other random bolts that gave me shit along the way. Spent a good hour putting the drivers side oil pan bolts back in, they just refused to work. Also the bolt on the ac bracket that the tensioner plate pivots on took another hour and a half for some reason. As long as you have good tools and at least a full day to work this is a pretty easy job, much cheaper than going to a mechanic too.

                        I eventually came up with a solution to the crank bolt problem. To keep the engine from turning i took a 15" ratchet extention, put one end in a big socket and placed it against part of the frame, and put the other end on a raised part on the harmonic balancer. Once that was wedged in there i took a socket wrench w/ extension, then put the jack that came with the car over the handle and gave it hell. Broke the first wrench, but i tried again going nice and slow and it came off. It was one of those "there's no way that should have worked" moments.



                        The old chain had about an inch of slack, i'm not sure if it was stock or not but it was old.



                        new chain:


                        I was planning to clean out the engine bay good and do a few other things but i ran out of energy after 20 hours and saturday is my only day off. I did scrape about a half gallon of oil sludge off of just the front of the engine, still needs a lot more cleaning.

                          I should have suggested a double roller chain. They don't stretch as much over time, but good deal in any case.

                              I tried to get one but none of the stores around here had any in stock and i had to get it done on saturday. I am probably going to get a new engine, or upgrade somehow before that one goes bad so it shouldn't be to big of a deal. I barely drive 400 miles in a month so it will last a while.
