Line Up Cam Shafft Pulley 1990 Loyale.

1990 Subaru Loyale turbo automatic:

My drivers side timing belt slipped due to the tensioner going bad.
Now the cam is off. How do you turn the cam pulley to get the mark
lined back up?
 
I just use a wrench on one of the three bolts. Need to do it slowly t
prevent snapping it off. You do know how to time the camshafts? If yo
time them with both timing marks "straight up" then it is wrong.

The manual says to line up the middle of three marks on the flywheel
with a sribe on the timing hole cover . Then line the mark on drivers
cam pulley with the notch on the plate behind timing chain cover.
Thats is suposed to get that cam back in the correct position. Does
that sound right ?
 
Yes it does but after the first belt is installed, the engine has to b
rotated one revolution. Because the cams turn at 1/2 crank speed, thi
moves the timing marks 180 degrees on the belt just installed. Just mak
sure when both belts are installed, timing marks one one camshaft are i
alignment and the ones on the other camshaft are "off" by 180 degrees.

Hi,

Sorta... it's been a while since I was inside my engine, so I don't
recall whether the mark you mention is at the 12 o'clock or 6 o'clock
position, but I'm thinkin' 12 o'clock (the book should have the
picture.) Regardless, the cams are timed so the marks are installed to
be 180 deg OPPOSITE each other when everything's ready to be buttoned
up.

In other words, you put on the first belt and time its cam at (assuming)
12 o'clock. Then you rotate the engine 360 deg so that cam is now at 6
o'clock (cams turn 1/2 speed of engine), and install the SECOND belt w/
its cam at 12 o'clock.

Otherwise, you're never gonna get the engine restarted! (We won't ask
for a show of hands from the "Don't ask me how I know this" crowd!)

The drivers side belt is the one that slipped . The passenger belt
didnt slip. Isn't the passenger side still in correct position? The
book implies that the drivers side cam pulley just needs to be
realigned when the center of the three marks on flywheel are lined up
with the scribe on timing mark hole.

I see what you guys are saying about 180 dergree difference. I was
trying to avoid taking off the passenger side timing belt cover,
because I didn't want to remove the crank pully. However I can see
that I'm going to have to, to see that the cam pulley timing marks are
180 different. Thank to everyone

Update:
I pulled off the passenger timing cover and the belt is still lined
up correctly. Both cam pulley timing marks were already marked with
yellow paint Right no the passenger side is at 6 oclock and the
drivers side is at 9 oclock..I need to move the drivers side to 12
oclock l'm still trying to figure out a way to slip the drivers side
timing belt off the cam sprocket so I can realign it without taking
the center timing belt cover off. That would require taking the crank
pulley off which sounds like a pain.
 
Use the dot on the sprocket and the notch in the cover to time the cams.
6:00 and 12:00 are just general, get you in the ballpark, terms. Also yo
could have just pulled the timing cover end cap to verify the position o
the other sprocket.

Normal procedure timing the belts involves first installing the driver'
side belt, rotating the engine 360 degrees and then installing the othe
belt. But you will have to reverse this procedure since the second bel
is already installed. You need to keep rotating the engine until th
passenger side timing marks, the dot and notch, are in alignment and th
pointer in the bellhousing is pointing at the middle of the 3 lines on th
flywheel. Use this as your starting point. Now rotate the engine one ful
revolution and install the driver's side timing belt. You know the belt
are installed correctly by just rotating the engine and stopping at th
middle timing mark. One dot/notch on one of the camshafts will be i
alignment. Rotate another 360 degrees and the other camshaft dot/notc
will be in alignment. Sort of confusing but you'll figure it out

At this point the passenger side is lined up with the notch/dot on the
cam pulley and the belhousing pointer is in the middle of the three
lines. Its at approx. 6 oclock.

The drivers side dot is at approx. 9 oclock The drivers and passengers
timing belts are still connected.. So the cam pulley is out of line,
it should be at approx 12 oclock where the dot/ match right now.
Right? If I rotate the engine, drivers side will still be off by the
same amount. Dont I just take the drivers belt off and manually rotate
the drivers side cam sprocket so the dot/notch is aligned at approx.12
oclock. At that poiint the passenger dot/notch will be 180 dergrees
from the drivers dot/notch.

Hi,

Another thought since you're in that far:

Install NEW belts, both sides! Cheap insurance... you don't know what
the old belt went thru when it "slipped" plus do you know for sure how
many miles are on the belts?

Inspect ALL the tensioners and pulleys. ANYTHING even possibly suspect
should be replaced. If one side's tensioner went, it's safe to guess the
other one has the same kind of mileage and wear...

Do the "standard" replace all the seals drill: both camshafts, the crank
mainseal, O-rings on the back of the oil pump, and the small seal at the
front of the oil pump.

Consider very seriously replacing the water pump, too.

Yeah, this will cost you a few extra bucks. But in the long run you'll
save time (and possibly money) while possibly avoiding some failures and
almost certainly a leak or two...

I just replaced the water pump, this morning.I can't find good
instrutions on the crank and oil pump seal replacement. Also not sure
how to hold tension on the timing belt tensioner. My Chiltons manual
doesn't go into any details on how to do eithe task. I have nerver
done timing belt/front crank/oil pump seal.
 
The manual version I worked on had some holes that you could insert a drill
bit into. Have you tried rotating the engine while viewing throught the
window?
