Pulley alignment issue
I know the community is full of much more experienced people than I, and after hours of trial and error i think i need some more guidance. My crankshaft pulley and the water pump pulley won't quite lineup. I have a long water pump and appropriate pulleys and the water pump and the alternator line up perfectly. I used the tool to install the balancer on my crate 350 and the balancer sits about 1/2 of an inch from the timing chain cover. My question i guess is my balancer on all the way? is that the reason my pulleys won't line up? Or is there some glaring issue that I have completely looked over?

Re: Pulley alignment issue
Have you tried an original water pump pulley, even if it's just a single groove to see if it lines up?

Re: Pulley alignment issue
Double check that the balancer is all the way on, use the bolt in the middle of the crank and torque it to spec.
If you only need a little there are spacers for the water pump pulley. The have the pilot hole in the middle and the 2 sets of 4 holes for the fan. Usually one of these will bump the WP pulley out to get it to line up with the crank. I think they typically come with the water pump, but you should be able to find them loose at the parts store. |

Re: Pulley alignment issue
I could shim the water pump but then it wouldn't like up with the alternator.

Re: Pulley alignment issue
I had to shim my PS and my alt to get mine to work. I'd start with water pump shims and go from there

Re: Pulley alignment issue
Thanks for the guidance, going to try a new balancer first and if that doesn't work i will shim the water pump. Thanks again.

Re: Pulley alignment issue
I'd bet with OEM pulleys and brackets the problem would go away. Seldom do the chrome parts fit as well as GM did. I'm no chrome hater, just poor aftermarket part hater.

Re: Pulley alignment issue
Did you heat the balancer and cool the shaft before trying to install it ? Slowly heating the balancer in water until boil and packing the shaft in ice for an hour really helps to ease install , carry it out to the truck in the hot pot ,remove the packed ice bags use some spray lube line up the keyway using heavy gloves and using a short section of 2x4 and a 2 lb hammer drive it home . Works everytime. I doubt there is anything wrong with your balancer ,just close tolerances .I wouldn't try using the bolt to pull it in you'll just turn the engine or strip / snap off the bolt

Re: Pulley alignment issue
They don't sit flush when fully bottomed out. Judging by where the timing pointer is falling on the harmonic balanced it is fully installed.

Re: Pulley alignment issue
Good to hear that my balancer is on all the way, I was reading how these aftermarket pulleys might be misaligned if you use different brands for the water pump and crank pulleys. So I ordered a brand matching pulley...maybe this will solve the problem. Thanks for the pictures gives me peace of mind knowing that I have done this correctly.

Re: Pulley alignment issue
I went through hell with chicom pulley's. The speed shop recommended I bring them back if they did not fit. I wonder what they knew that i did not. when you gotta shim everything to make it fit......something is very wrong. I took anger management classes after that.PTSD

Re: Pulley alignment issue
I won't use chrome nuttin. I've never had to shim nuttin. I won't use chrome nuttin.

Re: Pulley alignment issue
I fought misaligned pulleys for years on my truck. Before I installed factory style AC (where you have another belt turning the water pump) I would break the bolts holding the alternator on to the block - which of course then stops turning the water pump. So there you sat. My temporary fix was to carry spare bolts and a couple of wrenches everywhere I went.
What I didn't know was that at certain, higher rpms, the out of alignment belts set up a frequency where the alternator bracket looked like a just plucked guitar string - which of course eventually sheared off the bolts. Long story short I asked a local truck parter guy (da-burb) for a set of pulleys from a factory, unmolested truck. With air as I was planning on that already. That set aligned perfectly. I haven't touched them since. My recommendation is throw the aftermarket crapola away, get a factory set, paint 'em to match what the general did. And don't look back.

Re: Pulley alignment issue
There is a lot of give info on this site and they were real helpful on the phone: http://www.alangrovecomponents.com/Catalog.htm
They have a lot of custom applications available and nice OEM spec pulleys too. I needed a new OEM style PS pump pulley but didn't want to spend the time to find one and get it powder coated, their OEM style fit perfect and solved my alignment problem.
