Question Rotating crank pulley

Hi guys,

Finally my friend and I are going to tickle the timing belt for the first time (both of us) tomorrow. Really excited and anxious about it cause I have NO extra for another Eng...

Anyways, I have heard people saying to rotate the crank pulley to line up the timing mark and hand rotate the pulley to make sure no contact is made after the new belt is on. I am wondering do I do that in neutral (I have a 5MT) and with e-brake off?

I know if I need to take the crank bolt off I need to pop it in 5th and e-brake/brake on. I figure that would lock the crank tight but when I need to turn it I need to do the opposite.

Am I getting it right?

Thank you so much. You guys have been really helpful!

Vincent

You are on the right track. Before my first TB job on my '00 Outback, I did some searches here and on google for Subaru timing belt and found many good guides showing how to do everything w/ pics. I also had a Haynes manual and some Subaru Service guide info as well.

I actually drained & removed the whole radiator first for more room, easy & worth it to me.

Yes, engage parking brake; then put the trans in neutral to manually rotate the crank until the timing marks line up on the cam & crank pulleys. I loosened all the spark plugs to make it easy to turn the crank manually since there's no compression with the air in the cylinders escaping around the loose plugs.

To break the crank bolt loose, I actually put the trans in 5th gear and put a couple big screw drivers in the access hole for the flywheel / starter gear teeth (on top of motor, small black cover that pops off covers this area) to hold the crank still while I broke the crank bolt loose. An impact wrench made this super easy, otherwise breaker bar & pipe to extend the handle length works as well.

Once I got everything reinstalled (new timing belt, tensioner, etc) and spark plugs still loose, I manually turned the crank again to be sure that all of the pulley / crank timing marks lined up during rotations and that there wasn't any piston to valve interference before I ever started the motor up. Since that was the first time I'd ever done a timing belt job myself, it helped me immensely in doublechecking that I had done everything correctly and wouldn't trash the motor.
This is my basic knowledge, others might have far more detailed recommendations.

Thank you.

I have been reading... or more like cramping a lot of threads about how to do a timing belt job for the past month since I got my car. I just want to re-affirm that I'm on the right track.

Thanks again!

Vincent

I learned how to do my timing belt exclusively from this forum and advice like yours.

Thank you everyone for the help.

You can also use a 24" chain wrench to hold the crank pully. Use a piece of an old alternator belt to protect the grooves.
