timing belt question

just opened my timing belt kit with the pulleys that i got online, seems the belt doesn't have the line up markers anywhere on the belt. just the brand name etc. my question is there any way to install this belt without the marks, i search and found nothing but teeth counting can someone fill me in on this.

any help would be great, if worst came to worst i will buy one locally

thanks

The marks on the belt are merely a convenience, they are NOT critical in any way.

Simply line up the timing marks on the crank and cam sprockets with the corresponding marks on the motor, and install the belt starting with the crank pulley. From there, put the belt on the proper pulleys, going in a counter-clockwise direction, keeping tension on the belt. All the slack in the belt will then be right at the tensioner where it should be, so when you tighten it, everything will still be line up perfectly.

If you wanna be extra sure, rotate the crank 2 revolutions afterwards, and make sure the marks still line up...if so, you're golden.

Hope that helped!

You align the pulleys to their top marks and count the teeth between them as the thread states. Keep in mind that the tensioner will move things a little, so not all the marks will be dead perfectly pointing upwards on the pulleys. You should figure on that movement setting the pulleys a little straight.

You can make your own marks....Its pretty simple...

Along the belt there are teeth and troughs. We will say if there is a rubber ridge, then that is a tooth. If you are in between two teeth then you are in a trough.

Put a mark anywhere along the belt at a trough. This is the mark for the passenger side cam gear. Then count 44 troughs going clockwise and put a mark on the trough. This is for the crank gear. Then count 40.5 troughs. Yes 40.5, this will land you in between two troughs, which is a tooth, put a mark there. This should line up the drivers side cam gear.

When you go to put the belt on, get the cam and crank gears aligned close to the markers on the service cover. Then install the belt and make sure that the marks on the gears are perfectly marked with your marks you put on the belt.

Also, white-out works good for making marks on the belt.

I haven't ever really been able to get the marks line back up after rotating the engine. I probably didn't rotate the engine enough. Just keep that in mind if you plan to use the above method to check yourself.

Sorry if I was being unclear...I'm only talking about lining the marks on the sprockets back up with the marks on the timing covers & oil pump. I wouldn't even try to get the belt marks to line up after turning it over, hehe. Most of the t-belt jobs I've done didn't have marked belts, so it's just standard practice in my (twisted) mind.
