Pulley alignment Problem on '67 327 w/ps

Hello all,
I'm having a problem with my crank, waterpump and power steering pulleys (not) lining up. I haven't installed the alt yet. I have a new aftermarket short water pump that measures 5 5/8" from the face of the block to the face of the pulley flange as it should. I am using all stock pulleys. (They aligned fine prior to dissassembly). The crank pulley is 1/8" too far back for both the waterpump and the power steering pulley. Can the harmonic balancer be too far in? Can I/should I pull it out 1/8" to align the pulleys?

First, please go over to the Alan Groves Component site and see what the measurements are that they list for the "three"(?) water pumps that can be installed.

Then go from there.

AND I still have to line my p/s pump up too.

pdq,
I went to that site and that is where I got the 5 5/8" dimension from. I am using the same stock pulley that was on there prior to the rebuild. When I mount the crank pulleys, the ps pulley is 1/8" too far back and the wp and alt groove don't line up either.

Make sure you are using all "short" waterpump pulleys. There are different pulleys for short and long pump, as well as big blocks are different. Also look on the CRG site for part #'s etc.

Re: Pulley alignment Problem on '67 327 w/ps

I know of two short water pumps but I dont know what the pulley flange depths are , Go to Stewartcomponents.com,, the people that make nascar water pumps, they list them both. More than likely your crank pulley is right, You may have to use the correct water pump or the water pump shims to correct the water pump. Then deal with your ps. There are two pullies here , grove and press on. I hope you have the grove type.

Ok, I found it ,, one flange depth is 5.625 and the other is 5.795, both are short design sbc. You can took at Alan Grove also.

I do now, kinda. I just bought some 2" fender bolts that I will hog out until they fit behind the crank pulley without interfering with the lip on the center hole. Looks to be about 1 3/8" diameter or so. Two will give me 1/8" thickness. Now all I need to do is find out what kind of bolts the balacer is threaded for for the pulley attachment bolts. It sure isn't the stock 3/8' or 5/16-24. Might be metric for all I know. Geesh, I wish just one project would be easy on this car!

Re: Pulley alignment Problem on '67 327 w/ps

If you are going to "spacer out" the crank pulley, use 3/8 flat washers and stack them, maybe three each needed, for the required 1/8 inch. At least these washers are punched out from stock sheet and their weight difference is neglible. You might find a gr 8 washer of the thickness needed.

If you rework a fender washer to fit between the interface of the pulley and the h/bal, have it balanced after the work.

The thread in the balancer is 3/8-24 UNF. Use the length of bolt to include the pulley, washers, and thickness of the web. No longer than a thread or two showing after installed.

On another note, did you replace the crankshaft timing chain spocket? Wonder if the replacement was the same thickness as the one it replaced?

Exclamation Re: Pulley alignment Problem on '67 327 w/ps

You may be gifted if spacing out the crank pulley with washers works and does not come loose and slice the radiator. All crank pulley driving force is on those bolts,, Thats one reasone they are 3/8 x 24 . Crank shims are a no no. When I said shims, I meant for the water pump . You need to get some good reliable pulleys on the crank that you know are correct and then go from there. I think you are running same combo I am ,,, My engine did not have ps but i added it and it was a matter of getting the correct stuff to bring it all together.

A GOOD Machine Shop can press the water pump pulley flange to locate it anywhere you want it if not mistaken. Either the flange, bearing OR the impeller....

AND yes, the balancer bolts need to go ALL the way through the balancer b/c some of them have their threads recessed quite a bit from the front!!

As for the fender washer. Just make sure it is cut down TRUE round and you should be fine, imho.

Use Grade-8 stuff here!!
