Timing chain

[eclipsespeed2003]

Does anyone know how to install a timing chain onto a 2000 LS? The person working on the car already took the old one off but doesn't know how to put the know on back on. He doesn't know what to line up the new chain with.

You forgot to say if it was a V6 or V8... but if it is a V8:


First thing you want to be absolutely sure about is that the cam bearing caps were installed in thier original locations. This is very important, each has its own specific lash.
Note: You will need a crankshaft positioning tool mounted durring installation to maintain TDC.


-Start with LEFT head!-
1: Put crank shaft @ 45 degrees @ ATDC.
2: Colapse the hydraulic tensioners (you will see a valve on the tensioners, press it with a paper clip, or tiny pick to relieve the pressure). Then properly position the tensioners. After positioning, install the secondary timing chain tensioner bolts.
3: Install the Intake sprocket, exhaust sprocket, chain, and damper as one unit. Install the bolts in both sprockets finger tight for now (dont forget the exhaust sprocket has a washer.) Reset the timing chain tensioner. (open the check valve again and squeeze with your fingers)
4osition the crankshaft gear and timing chain over the crankshaft as one unit.
5: Install the timing chain tensioner (a large zip tie works well to hold the slack while working)
6:Use the camshaft positioning tool to lock the camshafts while tightening the sprocket bolts.
Crankshaft sprocket timing marks should be positioned forward.

You will also need a new crankshaft pulley bolt and washer.

This is all i can remember off the top of my head, you will obviously need torque specs and sequences. I will check tomorrow if i remember, and put in all of the missing info, but you can at least get everything assembled for now. (unless one of you other LS guys here can copy/past it from your own tech DVD, i dont have mine on this computer.)

But, in my honest opinion... Have someone who knows what they are doing finish the job. Everything should have been marked from the begining.

Oh sorry, it's a V8. We ordered the Chilton book but it's supposed to take like 2 weeks to get here. I was just hoping someone could help me out so he could finish it sooner. Thanks for the information, hopefully you can get me the rest.

The local Library is a good start.

Timing Chain Replacement

Just a few quick notes....

1 >>> This job can be done without the speciality tools, that the service
manual refer to... (Crankshaft Positioning Tool, Camshaft Lockdown- Tool).....

2 >>> And this is only my opinion...... Replace the hydraulic tensioners !!!!!!
Not 100 % positive, but I think my timing chain failure was caused
by a Tensioner failure... I replace both upper tensioners (one failed)
and I replaced all four chains..... Due to the magnitude of this job,
it is worth replacing all four chains, and the upper tensioners... When
the car is back together it is better to know that all these related
parts are new....

3 >>> I was unable to locate a camshaft hold down tool, so it was easier
for me to just remove the entire camshaft, rather than break the
sprocket bolts....

4 >>> And to repeat what an earlier post said, the Camsaft bearings caps
need to be re-insalled in the same location, and in the same
orientation... This is extremely important...

5 >>> All Torque to Yeld bolts that are removed of course need to be
replaced....

If anyone has any specific questions regarding this please ask, and I will be
glad to fill you in on what I have experienced.....

By the way, I did my timing chain replacement under my cover in my driveway.

It is a very difficult job to do, and if you have no past experience with automotive repair it is best to pay someone to do this job...

P.S. Besides parts, and my labor. I purchased plenty Aspirin, and Beer..

Re

I guess I kinda look at it this way...

I get the satisfaction knowing that I am doing the repairs, and not a mechanic that may or may not know what he is doing....

I have never and will never pay someone to do something I am capable of doing myself !!!

:iconcur:

About the only time I will use a shop is for diagnostic services when I can't figure the problem out or we, LvC, cannot figure it out.

Well i guess its good idea if you've already spent thousands and thousands of dollars worth of tools and have everything you need to do the repairs comes in handy, and in the long run will pay for itself rather than paying 100 dollars and hour for someone else to fix it. Guess the mechanic can just as easy mess up the timing as good as the next man right. lol.

From what I have read the shops are using fewer Master Techs on jobs that Ford says requires a Master Tech, including recall work which is a major no no. Instead the shop managers are hiring newbies with little or no experience and using Master Techs as Mentor/Managers. So yes it is more likely these days for you car to get screwed up than if you do the work yourself.

As far as tools ago to dat I have only need standard and phillips screw drivers, 8,9,10 and 13 mm sockets and wrenches. A deep 8 and 10mm socket and a crescent wrench. All of these you can get in a tool set for under 100 dollars.
