I need timing alignment help quick!

Eric SS · 11-03-2001, 02:18 PM

OK, I'm about to put my rocker assembly together and I can;t figure out how to allign anything because of all the marks. On my crank timing belt pulley there is a blue dot, a triangle, and a line. all in different areas.

On my two cam sprockets there are a big arrow, a blue painted on dot, and a little line like on the crank timing pulley.

What lines up with what??? Please help here.
Thanks

Eric

the aarow's point up on the cam pulleys....you will see white dots painted on the CAM and CRANK pulley. There will 3 white lines on your T-Belt...line that all up and you'll be set to go but MAKE sure all those white marks line up otherwise you just thru your valve timing all to hell.

I don't have any white marks on my timing belt at all. it is all black

Eric

Eric SS · 11-03-2001, 04:20 PM

Here is the first cam sprocket. Notice the arrows and dots and lines:

Here is the second cam sprocket. same stuff :

Here is the crank sprocket Notice it has an arrow, a line, and even another blue dot!:

What lines up with what. like I said, there are no marks on the belt

Don't listen to someone who works on Hondas!

The arrows at 12:00 mean #1 TDC. To install the Cam Belt, arrange the Cam gears and the Crank gear with the "Line" at 12:00. This will put them in APPROXIMATE position to install the belt. The left Cam will be loaded and the right Cam will not.

To install the belt, either go buy a new Cam Belt from Subaru or find a Subaru Service Manual so you can get the tooth-count between cam marks and crank mark. You should have marked these on the belt as well as the direction of rotation before you took it off. The position of the gears is only approximate because it doesn't really matter, the number of teeth between the marks is what is important.

What are you sealing your Cam Cases with? Don't use RTV Silicone.

Eric SS · 11-03-2001, 06:42 PM

Why shouldn;t I use RTV? That's what the Shop manual suggests and what was on it from the factory. Do you know how many teeth should be on the belt between gears?

Eric

SubyTechMaster · 11-03-2001, 08:59 PM

Here is the tooth count instructions from the SM. It is from the Forester book but is the same for Impreza.

Nevermind. It is too much work to post a pic here. I have the SM on CD and was going to copy the page.
Between the Crank mark and the R. Cam mark is 46.8 teeth
Between the Crank mark and the L. Cam mark is 43.7 teeth

After you set-up the belt and release the tensioner, turn the crank back and forth and check to make sure the marks still line up. Turn the crank over 2 revolutions and make sure the Crank and Cam marks still line up. Once you turn over the engine the belt marks will no longer match up to the gears.

I don't know what Service Manual you are reading, but Subaru does not say to use Silicone RTV. The solvent in the RTV is destructive to O2 sensors, and it doesn't work well. For the Cam Case Subaru recommends Threebond 1280B, part #K0877YA018. This is also what came on the engine "from the factory".

Hey tech master.... did you ever work at the dealer in walnut creek?

Eric SS · 11-03-2001, 09:56 PM

When you say right and left, you mean Left is Driver and right is Passenger correct?

Eric

Eric SS · 11-03-2001, 10:09 PM

OK, I must be doing somethign wrong.. No matter how hard I try, I can't get the timing belt on and the Tnetioner is fully compressed! Wht's the secret

Eric

SubyTechMaster · 11-03-2001, 10:09 PM

That is the universally accepted referance. As though you are seated in the Drivers Seat.

Eric SS · 11-03-2001, 10:20 PM

Just wanted to make sure we were on the same track. so waht the secret to getting the belt on? it is Sooooo close.

Eric

Midwayman · 11-04-2001, 02:02 AM

SubyTechMaster, Hondatech actually has torn down ej25's quite a few times now. Dont discount it. He has practical experience inside of subary motors. Just cause he mainly works on hondas doesnt mean he doesnt know what he's talking about.

HndaTch627 · 11-04-2001, 06:00 AM

yeah that was a rather rude comment. But thanks anyways. Just trying to help someone out...oh yeah if you went and bought a new belt you'd have 3 white lines on it....cam crank cam....but thanks.

Eric SS · 11-04-2001, 12:15 PM

Thanks for all the help guys. I ended up going to Cobb Tunning's site adn saw something on it that said something about takign the red pulley off and bingo! the belt went right on. I counted the number of teeth and marked it there everything lined up perfectly. Now I am goign ot be putting the engine back in the car today

Eric

SubyTechMaster · 11-04-2001, 12:55 PM

While my comment may have been snide, it does not discount the fact that WRONG info was posted.

My apologies if I impinged on anyones honor.

HndaTch627 · 11-04-2001, 02:02 PM
