ive got a 77 cruisin wagon and the timing belt broke we messed with it and cant figure out how to get the crank pulley off the motor can i get some help???
can I ask a question... why do you need to pull the crank pulley off? to replace the belt you only need to loosen the belt tensioner.. Unless you are tearing the motor down for some reason.
My thought exactly.

Actually, I think you do need to remove the pulley to get the belt on the lower spline piece that is on the crank. If I remember correctly, it is because of the timing cover and the way it is designed. Plus I do not think you will be able to see the timing marks to line the belt up with the pulley in the way.
aimone, to answer you question. You need to remove the crank bolt. This may be difficult to do without air tools. You will probably have to remove the radiator to get enough clearance for the air tools. Once the bolt is loose, I just use a 3 prong jaw type pulley and the pulley just slides off. I does not take a lot of force to slide off. Good luck!
sorry tigger.. I have replaced the timing belt on my 1977 2.3 cruising wagon twice and once on my 1973 2.0 runabout last summer and didn't have to remove any pulley, just the belt tensioner. Oh yea... and also the 1980 2.3 that I just replaced the head gasket on in Febuary (I sound like a broken record.. I can change a timing belt in my sleep now :P ) anyhow.. it's difficult but it can be done and you can see to line up the marks.
If a "motor newbie" like me can do it.. well you get the point..
I think if the belt covers were left off from the last intstall, you might be fine. Not something I would do for a "driver". There have been posts about a small rock taking out the belt.
The metal outer cover can be removed fairly easy IF the car has the single groove waterpump pulley. It can be done with the double pulley too, but it needs to be BENT.
It is so easy just to remove all that stuff, and it makes the job even easier.
If the crank pulley is lined up with the time mark to o* and you don't move it, you don't need to remove the crank pulley, BUT from what I remember, it takes some work to get the new belt into place.
I only had one crank pulley give me ANY issues during it's removal after the bolt was out.
I agree with TP72. Once you get the bolt out, MOST of the time all it takes is some mild effort of rocking the pulley in different directions and it will slide off.
BTW: If the car has a 4spd it should be easier to get the bolt out.

I have done over 100 belts on 2.0 and 2.3s.You must remove the lower crank pulley,snaking the belt in can damage the cords in the belt.you don't remove the tensioner.A 2.0 takes about 20 min,a 2.3 takes about 30 to 45 min.Most straight forward timing belt job there is.A 2 ear steering wheel puller will work to remove the lower pulley.
ok the radiator and stuff is already out and we have air tools we had to change the water pump also. the bolt in the pulley is it like a regular bolt or wut cuz i dont remember any bolt in there
Yeah it's a great big bolt, dead center. I can't remember if it's threaded backwards or not, but I believe it is.

No, regular threads; 15/16" IIRC.

take the time to do it right like earthquake mentions. just because it can be done one way doesn't mean it's th ecorrect way
I guess my manuals do say to remove the pulley so I have been doing it wrong. I've always done it the other way, I have small hands and fingers and I take my time. Never did like the way the belt had to be "squeezed" in but as I stated above I'm a "motor newbie" and I didn't feel confortable removing the pully.
..and Earthquake is right, just loosen the tensioner, I should have been more clear in that post.
CookieBoy,
I removed my pulley the first time I changed it then after that I would positon the belt just so and then snap it into place.
