Hey guys, just got the 505 in and have a mess of pulleys and brackets. Have no Idea where to begin with this. As far as I know they are stock 454, but I need a pic or something to get started. I looked in previous threads, but couldnt find anything that shows step by step. I have the haynes manual, but I not much in there either. Any help s greatly apreciated. New to this but eager to learn!!

There really isn't that much too it. First thing you want to do is is mount the crank pulley and water pump pulley as a starting point. You need to make sure they are in alignment. If not then you need to get some shims, Summit sells shim kits for both the water pump/fan pulley and the crank pulley depending on which one you need.

Once the crank and fan pulley are in alignment mount the power steering pump and check the alignment on that. Then do the same with alt. There are only 2 brackets for mounting each and it's almost impossible to put them on wrong.

If you still have problem mounting either one ask, maybe someone can't get some pics and a better description.

Well, thats part of my prob. Is how to mount the crank pulley. Does the harmonic balancer bolt come out and pulley goes on? Is there a spacer between the pulley and balancer Im missing? A pic would probably help.

Thanks

No, there should be a hole in the center of the crank pulley, it's the large double pulley. The balancer bolt can be accessed through this hole. The pulley bolts directly to the front of the balancer unless you need to shim it out to align with water pump pulley. Bolt it on, no shims. Bolt on the fan pulley no shims. This is the smaller double pulley with a smaller hole in the center. Check alignment, a straight edge on the front of the pulleys works. Get the shim kit you need if they're not in alignment and get them lined up. Getting these 2 aligned is a must or you'll be throwing belts. You may or may not have to shim the alt and power steering pump to align with the crank and fan pulley. I had to shim the crank pulley, after that everything else lined up.

As far as a pic, you won't see much, just a balancer with the pulley mounted to front surface.

That makes sense. I was getting confused because the small block has the bolt in the middle that goes to the balancer as well as the three around. Just painted all the pulleys and brackets, waiting for them to dry. Thank you again, that really cleared it up. Ill let you know how it goes.

The BBC pulley setup is very much like the SBC setup. In fact I have my suspicions that the prior owner put a SBC crank pulley on the 402 in my El Camino. I ended up replacing all of the pulleys and brackets to get everything lined up and proper.

Note that there should be a lip to the backside of the crank pulley that indexes it into the harmonic balancer and makes sure it is centered. If you do not have that or it does not fit closely, then you have the wrong crank pulley.

Another thing you need to specify when asking questions about pulleys and brackets is if you are working with a short or long water pump ('68 and earlier tend to use SWP and later use LWP).

It has the lip. I have the long water pump. Just put that on. Now I need the bolts for the pulleys. Any particular type? I found the right size. Torque settings? Cant find them in the manual.

I would get Grade 8 bolts, a little blue Locktite and tighten them up. As far as torque, when the veins in your neck start to bulge, their tight enough :D I would guess around 80 lbs but not sure. Someone might have a spec.

Im going to send a pic of all the pieces that were given to me in a bit. There are a few I have no clue on. One huge odd shaped chunk of steel looks like. I know the crank and PS pulleys, thats about it. Going out to get the bolts now. Thanks!

Ok, here they are. Anyone know where these go? Was never good at puzzles.

Top left is alternator and the 2 bolts close together bolt to the water pump by the lower hose. The top right is PS. You bolt it to the pump and then to the hole on the right side of the water pump and the block under the #1 plug. Next is AC that bolts to the head I think and compressor. The one next is also AC and bolts to the back of the compressor. Bottom left is alternator top bracket and bolts to water pump at the top center and then to the intake. Last is also AC and bolts to compressor I think at the bottom rear. Hope this helps.

Top left ~ Lower alt. bracket.

Lower left ~ Upper alt. bracket/brace.

Top right ~ Lower power steering bracket.

Middle right ~ Upper power steering bracket.

The other two are your A/C brackets.

Johns right. I screwed up. The middle right is for the PS. Sorry about that.

Correct.

Do you have the long bolt and sleeve for the lower alternator bolt?

Thank you all, BIG help. So I can use the PS pump off my 350 the way it is?

Tim

These might help. No AC though. And missing rear bracket for PS.

Yes you can use your PS pump, just swap out the SB brackets for the BB ones. here is a pic of your AC bracket and how it mounts..

Ahh, I see. Wow, never woulda figured that out, looks like one of the bolts on the ac bracket is going to the valve cover?

No that bolt is for the compressor. I have it threaded in the bracket so I won't loose it :clonk:

Ah, gotchya. Good enough. I should have the brackets on by tomorow now.

Thanks again!

Tim

Yep, got a ton of bolts today at the parts store.

Thanks!

Ok got almost all of em on, except the upper PS bracket. Where does that one go? Does the PS res. tilt to the left? I included a pic,

Thanks

Try this

These might help for the power steering.
Note alternator bracket bolt to intake in the last picture.

That bracket goes right on the front of the PS pump and the adjustment slot goes on the water pump. Some water pumps have holes all the way through (long bolt with nut on other end) and some have threads at the hole (short bolt).

Ok, thats what I thought, but wanted to be sure. Thanks for the pics too,

Tim

Ok, another problem. Was putting on the PS pulley, and realized I didnt know how far to push it on. Far enough to line it up with the other pulley? Also the belt is too small. Didnt know if parts guy sold me the wrong part or I just messed up somewhere. I have the PS all the way over touching the water pump, but still wont come close. Please help!

Thanks
Tim

The pulley should bottom out, then put the nut on.

sounds like you need a longer belt, enough to have the fill neck straight up and down or a little cocked to the right. It should not be touching the WP.

Ok, It just looked like the pulley wouldnt be lined up with the crank pulley if I bottomed out. What slot does the belt go in from the crank to the PS? Looks like the crank has 3 slots.

Tim

It should only line up with one of them - in my case, the crank has 2 slots and it's the one closest to the engine.

When I did the swap. I changed the double pulley to a single one. As Mark said line it up with just the one. I also had to play with the spacer location. The pump actually lined up better with the spacer on the rear, not the front.

When I went through this I never could get the pump to line up right with the OEM bracket. Obviously they all left the factory like that and worked when they left.

I bought an Alan Grove LWP PS pump bracket and everything lined up perfectly.

What spacer are you refering to? I dont have any spacers on my setup..yet, do I need one?

Maybe this one. http://www.opgi.com/product.asp?catmainid=1&topcatid=27&chapterid=27&GrpCode=12015&ProdCode=C210178&yearrange==

Oh, hah, I HAD that totally forgot about it. Didnt know where it went. Where does that go? I guess Ill have to improvise, or find it.

Tim

Where does that go?
Go back and look closely at the pics. provided on page 2.

Got it, thanks. I guess this would, could be the problem. Ill keep you posted.

Tim

Well after messing with it for a few hours, I have determined that the upper bracket will not work with my long water pump for whatever reason. If the resivoir is straight up, there is about an inch and a half of space between the adjustable slot in the upper bracket and the WP hole. I think the best thing is to get another bracket, maybe a set of March pulleys and brackets:):confused. Maybe there is a difference in small block and BB PS pumps:confused:?

Any other thoughts?

Tim

My thought: Alan Grove Components 407LN.

Good call. Im going to order it.
