I'm in the process of changing my timing belt and I'm having problems keeping the timing belt on the cam gears.
When I took the everything apart, I noticed that the old timing belt was rubbing against the plastic housing.
Here's are some pictures of the OLD timing belt at 100K miles.
as you can see from the pictures, the edge of the timing belt was worn away.
here's the junk that I found on the timing belt cover
****new timing belt****
To make a long story short, I installed the new timing belt and found out that I somehow misaligned the cam to the crank and had to take everything part...again
I noticed that my NEW belt is ALSO falling to the same edge of the cam gears. Part of my new timing belt is already worn away.
After aligning everything correctly, I put the timing belt back on and activated the auto tensioner buy pulling out the holding bracket.
I then turn the crank several full revolutions manually while keeping an eye on the belt. After about 5 revolutions, I can see the belt coming closer to the edge and actually starting to fall off it. It doesn't matter which direction I turn it...both clockwise and counterclockwise give the same belt slipping scenario
If I turn it counterclockwise, it appears that the belt starts to slip off the intake cam first (cam nearest to the window).
The good news is that the marks always line up after each revolution.
Has anyone experience such a problem? Any suggestions?
When I changed the timing belt, I changed everything.
Belts, auto tensioner, water pump, bearings, spring etc
pretty much the only thing I didn't replace were the balancer gears, the crank gear and cam gears.
