Timing belt 1 day later

M

mbjj

I got the crank bolt loose and proceeded to change the belt. It was all
straight forward and I took care in each and every step. I noticed that the
left [passenger] side wheel moved a little as I was positioning the belt
and counting the teeth. I moved it back and used a smallish c-clamp to keep
it from moving as I completed the belt installation. When I had it on with
all the beltmarks lined up I ran it through one complete cycle [by hand] to
take any slop out of the belt and kind of just seat everything. I put on
the center timing cover and then tried to fire it up to hear my success.
Well, I didn't have any. It doesn't even sound like it wants to fire. Where
did I go wrong and what can I do from here. It's a '98 Impreza 2.2L 5
speed.
Thanks
 
Did you by any chance break off one of those 'lugs' on the crank pulley?
If one is broken off it won't start - they are used by the crank angle
sensor for firing sequence (and ,with the cam sensor, for RPM and other
purposes).

Also, the torque listed in some books for some Subaru crank pulley bolts
is low - has caused significan problems after a few hundre/thousand
miles. maybe someoine here can double check for you. What torque setting
did you use?

I'm going to go back out and check it here in a little bit. I wanted to see
if I had any responses first. I was extremely careful working in and
around the belt, pullys and gears. I did notice when I slipped the belt off
that the center gear [cam] slid out a little with the belt. Not enough to
come off but enough to get my attention and I slid it back and held it in
place when I took the belt off. I don't think I broke any lugs and as far
as I could tell nothing went wrong. Except for the passenger side wheel
moving a little. As far as torqing the bolt. I did not use a torque
wrench. I wanted to see if it would fire before I finalized everything. I
put the bolt in finger tight and used my socket to "snug it up" firmly but
no so tight that I would have to jump through the hoops of getting it back
off again. My question now is: The fact that I tried to start it and it
wouldn't fire [I didn't over start it 3 or 4 times maybe 2 times]. If the
left wheel moved a little, is that motor zero tolerance and did I
unknowingly damage any valves during the start process? I don't thing the
wheel moved enough to get the whole thing out of whack but the thought did
cross my mind.

First, here are two sources of info with pictures to help you check if
you did it right.
1) http://motor.com/ go to «motor manazine», click on «articles and
features», «back issues». The info you want is inside july and august
2001 issues. In both cases, look for «Foreign Service, Dan Marrucci»

2) The other is http://www.endwrench.com/pdf/engine/FtCamBeltReplaceW01.pdf

That taken car off, it could be a number of things. (1) Not using the
proper marks on the pulleys to line up the belt/pulleys/mark on the
case. The info you'll find at the adresses above will help you check
that. (2) You probably had to remove the crank and cam sensors. Did you
put them back and reconnect them? (3) You might have interverted the
left and right cam pulleys. They are not interchangeable.
Good luck and let us know how you make out.
Gilles, Montreal.

Well, I went to motor.com and read the articles. There were no pictures. So
I tried the website using windows and still no pix. Here is what I found
when I re-examined the belt. The sensors are no issue. I did not have to
take them off to get the belt free. I did, though, retrace my steps and
tried to reproduce the belt/sprocket alignment again. This time I found
out that 2 of the 3 sprockets line up. Center/right or center/left. None
matched up like they did when I installed the belt originally. My question
now is: How do I get them to line up again? Each sprocket has a benchmark
with a paint dot. The left and right sprockets each have an arrow along
with an allignment mark. But they aren't in line with each other.
According to what I have read, I was to allign the benchmarks and paint
dots with the marks on the motor. Which I did, I thought. I lined up the
painted lines on the belt [ I thought] according to the diagram in my
Haynes manual. Now when I tried to reproduce that [belt marks in proper
sequence], the left [passenger] side sprocket mark is pointing to 9 0'clock
while the others line up correctly. What is my next step? Do I loosen the
bolt and just allign the sprocket? Do I take the belt back off and allign
the sprocket that way? What are the arrows all about on the left and right
sprockets? Should I use them to allign the beltt? This is my first attempt
at this so any help would be grateful.

Check your email. I sent you a PDF file that should help
 
Yes. evidently the arrows are only for TDC positioning of the cams for
valve work - not used for TB installation. And it is normal for the
marks on the belt to NOT line up after the engine has been rotated.

I wish someone would confirm the correct torque value for your pulley
though. I have read there are incorrect published numbers that have
ruined crankshafts. beware

Like someone else wrote, it's normal for the marks not to align once the
belt has been mooved at least one turn (I found out the hard way).
You'll have to remove the belt and try once more.
ON the Motor Magazine's site you have to click on the PDF (Acrobat)
version to get the pics with the text. The EndWrench adress I posted
leads you directly to a PDF file. If that did'nt work it's because you
dont have the PDF reader that's needed to have access to these files.
It's free. Make a search using «Acrobat reader» and you'll find it. Just
a fast download.
I read someone is sending you a PDF file. You'll also need this reader
to have access to it.
Good luck.

I have the latest Acrobat reader and it's a 13.4 megabyte
download...pretty substantiol if you don't have broadband...
 
Keep spinning the engine and they will eventually line up, or take the belt
loose and manually spin the cams (not just the sprockets)...remember..Top
