Default Orifice tube 01 blazer

hello, i just replaced the compressor and condencer. I bought the kit on ebay for about 300 dollars. My problem is i somehow forgot which way the orifice tube goes in. I tried sliding it in both ways, but it dont seem to want to go in. Is it keyed or something. Please help, I just left it out and put the old evaporator on and pulled a vacuum so that the air dont stay in system. I ended up breaking the new orifice tube trying to force it in thinking the new o ring was just tight. Is it normal to be that tight?

thanks, I dug around all night last night and found a few diagrams that showed that the small end goes in first. Im not sure how i convinced myself that the long end went in first. I got the new tube and im gonna try to install it correctly this time. Ill post final results. thanks very much 2door.

Default update

Update, Well i installed the orifice tube the correct way and everything slid together like it should. As of now, no leaks. A couple things are a little weird to me though. The compressor seems to be running cold where my last one was running hot. It also kinda makes a little racket on the front of it as it is running. It isnt much but there is some noise there. So far everything seems to be working as it should. Thanks for all your help and hopefully this compressor lasts a while.

My compressor is a little noisy too and has been for the 5 years I've owned it. I've come to regard it as a design feature. <G> The returning refrigerant cools the compressor. Might be you were a bit low on charge before and this time of year you're not working the system too hard anyhow.

well my compressor is definatly bad. When i turned it on today, i thought it was going to scatter. it shakes violently as rpms increase. could this have to do with my installation or did i just get a bad compressor? I made sure to vacuum every time i opened a port or anything. The compressor had 8 oz of fluid in it so i did not add any.
