Belt alignment problem
 

Been slowly getting the engine back together and have this problem I cannot figure out how to correct.

New OEM engine block with new Promaxx aluminum heads. OEM brackets and power steering pump.

Sea water/fuel pump alignment looks great.

Power steering and alt appear to be almost 1/4" too far forward. If they were too far back, I could use washers and move the bracket forward. Not sure what to do to move it back?

I'm kind of thinking the Promaxx head is a bit too long. In the pic you can see the head sticks out more than the intake manifold (even side cylinder head sits about flush with the intake manifold) and even a little bit past the engine block.

I know I can shave a little off the "bosses" (raised up area around the mounting bolts acting as stand offs) of the bracket to bring them closer, but not a 1/4"

Please let me know if I'm missing something here. Thank you

Sea Pump side. See how it finishes about even with the intake manifold?

These are what I'm talking about shaving down a little.

Great write up and photos.

Have you contacted Promaxx?

Are they longer at both ends?

Can you press P/S pulley further on shaft?

Do the water pumps pulleys line up with the crank ok ? Hard to tell from your picture.

I have not contacted them. Was kind of waiting for someone to say that's normal or not.

I will look to see if the other side overhangs, but I haven't noticed anything back there yet. But, there is nothing that needs to be perfectly in line either.

That is something i do not know. Didn't know that was even an option. Looks like the alt is not lined up either, so I would have to do both.

Water pump pully appears to be spot on with the crank. The sea pump appears to be fine also.

Thanks for the comments guys. I'll get some more pics for you soon.

PS pulleys are pressed on. They have some fore/aft adjustability.

Alt is under the PS pump?

Is the stbd side having issues?

How does the water pump pulley line up with the crank pulley?

just press the power steering pulley on some more.

+1 on trying to press on the PS pulley further, HOWEVER, make sure you look behind the pulley first and check to see if it has room to go.. If not and you try to force it, you can damage the seal.. I dealt with this on my 496... There was some shenanigans going on with the power steering... It had some weird mixup of shaft diameter and pulley design that didn't seem to align with any of what mercruiser said it should be so I had to get creative to make it work..

Does Hardin/CP Performance make a bracket to fix this? Try calling Hardin Marine and ask them.

Honestly? Just use pulley shims. Shim out the main pulley and possibly the water pump pulley if it throws off that alignment. Save the headache

Spoke with my engine guy, and that's what he said too.

Shim the crank pulley out. Shim the water pump pulley out as well.

Then just shim the sea pump/ fuel pump bracket out too.

Didn't know this was even a thing.

I will still look into other options though.

Thanks for the suggestions

Yes, ALT is under the PS pump.

No issue on the STBD side. Engine was dynoed with the sea pump mounted fuel pump.

Water pump lines up great.

It does look like they have possible options.

The good news is, I'm an idiot. The bad news is, I'm an idiot.:whistle:

Not sure what I did wrong with the straight edge? But I found a straight piece of steel dowel rod and placed it on both the back and front of the pulleys. I'll be damned if they didn't match right up.

Thanks for the suggestions guys. I'm just going to roll with it and see if i chew up any belts. IF that happens, then I'll look into the crank pulley spacer.
