...Today is the day I start my Maxima for the first time in 2 weeks!!! :shakeshout:
I have been performing the dreaded Timing Chain/Tensioner replacement job and it has actually gone fairly smooth. I worked on it for 4 full days so far, by myself, and all I have left is to put on the main accessory belt, fill her up with oil and antifreeze, hook up my battery and turn the key... WISH ME LUCK!!!!
I have taken some pics along the way, these are just with my cell phone... more with camera to come. So I thought I would share for anyone interested in seeing this job in action...
First, here is a list of the items I needed to perform this job:
SOME NOTES TO REMEMBER:
Remember to change your water pump while you are in there (and don't forget the (2) additional M8 bolts needed to remove it!)
If you do not own a set of SAE Allen wrenches, you will need one in order to remove the tension side guide bolt inside the timing chain cover.
I COULD NOT have done this job without a breaker bar, 2 swivel socket adapters and various sizes of extensions for my ratchets (BOTH 3/8" and 1/2")
The plastic shielding on the back of my alternator was so brittle it broke to pieces when I handled it. I did not remove my radiator to get the alternator out, I simply removed the thermostat and lower radiator hose and it slid out (TIGHTLY) through that whole. I had mine tested while I had it out (100K miles on the car) and it checked out perfect (outputting slightly over 15 volts). I got some electrical parts cleaner and dielectric grease to try and protect the, now unshielded, solder joints.
Get both new accessory belts and replace them now. Now is the time since you have the power steering pump free anyway!
I did this job WITHOUT using any of the Nissan specified tools (J-50288 or J-50246) as they were on backorder. To get around this, I did three things:
1. I followed the accepted method of using a breaker bar and cranking the motor to release the crank bolt.
2. I kept all of the tensioners, guides and chains on while I broke the Camshaft sprocket bolts loose.
3. I bought and replaced the primary timing chain tensioner. Purchasing this piece gives you the needed "tool" so to speak in order to hold the secondary timing chain tensioners retracted while you work on each side.
BEFORE starting on this job, I HIGHLY recommend printing out all of the sections of the Factory Service Manual that relate to the timing chain job and putting them into a binder that you can keep with the car while this job is performed. IT IS A LIFESAVER!!! And make sure you print out all of the removal/installation sections for the alternator, power steering pump, water pump and AC compressor. This will ALL come in handy more than you realize.
This is the diagram that I used to set my timing. I turned the motor over manually until the timing marks lined up just like this. Then I just aligned all of the new equipment this same exact way.
I will say this: The primary timing chain has a goldish link and the other (2) links are a dark blue-ish color and do not look like copper. Finding them on the one on the car is difficult but they are apparent on the new one.
Perhaps the tension side guide uses a different material now? I know the color changed and feels like a different material...
Right side assembled
Left side disassembled
Secondary timing chain differences
Make sure they are lined up right!
And this is where I left her last night:drool5: I can't wait to get home and give her a turn. Any last minute recommended checks before I crank it up (besides saying my prayers)? Sure wish I could pull the plugs easily so I could rotate it manually and make sure she spins free... guess I'll just have to take that chance!
::EDIT:: The Max started right up with no issues just yet... only time will tell! Thanks!
