I bought this truck, 92 C1500 305 TBI, last week Monday. It's great except for this issue. I noticed, when I was looking it over while it was running, the water pump pulley wobbling and the belt wasn't on the crank pulley all the way. I figured it was just because of the water pump bearing being bad, and it was so I replaced the water pump and fan clutch. After putting it together, the moment I turned it over the belt came back to ride on the back of the crank pulley. I've measured the balancer and pulleys and they are correct from the information I can find and measuring against ones at work. Still I replaced the balancer tonight and have it fully seated, and while it's better, it still needs to go back some. I can't find any kind of shorter pulleys for this other than an under drive pulley which only would change the diameter. It's between 1/4 and 3/8 out past everything else.
I'm stumped.. I have no idea how it got this way. I don't know how long it's been like this. It's very odd, I never would have thought I'd see something like this and someone before me didn't notice when they put it together. I assume the vortec and TBI engines have the same accessory brackets, I only bring that up incase they are different and maybe they used later brackets for R134A conversion. Only other thing I can think of at this point is to buy aluminum spacers to put behind everything else to move them out. I'd like to not do that if I don't have to. Maybe fresh eyes can help me see what my tired and frustrated eyes are missing. I'd really appreciate it.
