Why wont my timing marks line up?

Install lower timing cover and harmonic balancer. Rotate the engine a few times then align the crank pulley to exactly zero. Check cams, you may have to rotate the crank once to bring the marks to the top. At this point the belt marks will not line up ignore this.

What happens if the timing belt is not aligned?

If a timing belt breaks, the engine will no longer work. If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. The heavier crankshaft will continue rotating by inertia, moving pistons up and down.

What’s the best way to replace a timing belt?

With all the timing marks lined up, route the new belt around the largest diameters first, leaving the smallest pulley or sprocket for last. It’s tricky to slip the new, stiffer belt over that last one, but you’ll get it after a couple of different wiggling, jiggling attempts.

Where to find the TDC mark on a timing belt?

(2b) The flywheel pulley TDC mark is accessible through a hole in the bellhousing. (2c) The camshaft TDC is easy to find — especially if you add white paint as we did. We cannot stress this enough: Be careful!

How to line up timing marks on a Subaru?

Then you can free spin the cam sprockets as much as you want with any tool you choose – since the crank is lined up, all 4 pistons are half way down the cylinder walls and nothing will touch no matter what you do. ^thats exactly what i did, got the belt on, everything works great. :sunny:

What does the timing belt do on an OHC engine?

The timing belt (or chain) is the sole component that keeps the camshaft (make that camshafts on a DOHC or V-type OHC engine) and crankshaft in sync.

When to replace timing belt?

Every car manufacturer recommends replacing the timing belt after a given time, and it is imperative to take this advice. The time or distance between timing belt replacement depends on the specific make and model of the vehicle, but on average it should be changed every 100,000 miles.

  What are the timing marks?

  A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel, being the largest radius rotating at crankshaft speed and therefore the place where marks at one degree intervals will be farthest apart. On older engines it is…

  Is it important to replace my timing belt?

  The importance & benefits of replacing your timing belt. Your timing belt helps run many fundamental parts of your car, including the vehicle’s engine, alternator, air conditioner and power steering pump. In older vehicles, the standard timeframe to replace a timing belt is around 60,000 miles.
