having a problem my drive belts do not line up with my damper
i bought the truck about a year ago have had to replace the belts twice noticed the belts was a little out of line looking around i notice the damper was beat up pretty bad looked like somebody beat it on with a hammer so figured i would change it bought a power force damper used a install tool still the same problem damper seems to be all the way in how do you tell when its in all the way dosn't seem like the alt water pump pulley power steering pulley could all be off any help is apreciated

My guess is wrong/ba pulley on the balancer, or it's not mounted correctly. Nothing goes between the pulley and balancer. Unless it's the wrong damper, the only thing that could be fouling you would be a messed up "woodruff key" in the crank. I've never had any not go all the way in....I've even had to pull them back forwards a touch to line up everything. So I'd find another drive pulley.

thanks i will try a different pulley was just thinking about key wished i had changed it i will keep trying to figure it out will let you know if i figure it out just thought i would put it out there and somebody could put me in the right direction

Could it be possible that you've got the wrong crank pulley for the water pump setup? As there were two lengths of water pump, and I wouldnt put it past a guy that would put a balancer on with a hammer to have used the wrong pulley also. Is the crank pulley out of alignment by short or long?
-
i have the long water pump alt water pump power steering all line up crank pulley needs to go in about two inches i am thinking either wrong or defective crank pulley
-
If you're off by two whole inches then it's the wrong pulley....that or something is seriously jacked up! Sounds like he has a late 80's serpentine drive pulley and you need a mid 90's that only used one serpentine belt to drive ALL of the accessories?
-
Can you post a couple of pics?
-
will try to take pic tomorrow day off from work tomorrow so might figure it out
forgot to say what year truck its a 76 gmc with a 350 engine so no serpentine
hope to figure it out tomorrow if i dont will post picture and more information
thanks for all the help

I don't see how it would be possible to get a V-belt pulley off of any SBC and be two whole inches off. Yes pics would be great!

I think the long water pump came out in 73 so yours should be as you've said as long as nobody changed it over the years. The pulley almost surely has to be wrong. The balancer barely installs over 2 inches deep so I cant see how you could need that much more. Or maybe the balancer is wrong? When you installed it did you heat it first? I have a 4 lb one on mine and it absolutely wouldnt seat without both heating it in my oven and using the installer tool.

i got it finally it was the crank pulley the pulley was to long think it was a defective pulley chrome pulley made in china sure look good but now in junk pile where it belongs
thanks for all the help i got from everyone
