I have a 1969 mustang but the engine is a rebuilt 351W. I was not the one that installed the current alternator or engine. I am trying to put a single wire alternator on it and the bracket is hitting the water pump pulley. The old alternator was running off of the back grove of the crankshaft pulley. Does anybody know what the correct part number would be on the pulley? Does anybody have good pictures of correct 351W alternator and pulley setups?
I removed the starter to get to engine code and it is a 351w short block from 1969-1974. The car has power steering NO A/C.
In the pictures you can see the chrome alternator bracket touches the fan pulley. The pulley is not tightened in the pictures (it would not fit when bolted down). I could take some off the bracket but it would not leave enough on the bracket to work as a support. Is there supposed to be a spacer inside pulley? Any idea where I can find a fan spacer?
A Fan Spacer won't fix the problem, they mount Outside the Pulley. What is the Casting # on your Water Pump Pulley? I can tell you have a 4-bolt Crank Pulley which means that is a 70-Later 351W, probably still a C9OE- Block. Pulleys are all paired with each other to match belt grooves and Diameters. Your pulley might be too wide, or the aftermarket Alternator bracket is just not shaped correctly. IMHO
C8OE-D is the Casting Number for the 68-69 302-351W Water Pump. which means it's a 69 Water Pump. I was asking for the Number on the water pump Pulley. Like C9OE-8509-AA or something? Is your Lower Crank Pulley mounted by 3 bolts or 4? I can tell that your Water Pump pulley is a 69 Later Design, by the Extra Plate on Front. Pre-69 Pulleys were prone to Cracking at high RPM, so Ford added a Support Plate. .
Oh, and the C8OE-D Water Pump would be Correct for any 69 Ford 351W, Mustang-Cougar-Fairlane-Torino-Ranchero, etc. Not Correct for a 70 Motor. If you have a 4-Bolt Crank Pulley, the Water Pump might be the Problem.
Ok, a 69 Water Pump and a 70 Crank Pulley, I'm pretty sure those don't match together.. 3-bolt was used into the Early 70 Cars, then switched to 4-Bolt. the reason I say they don't match is that the Pulleys have to work in conjunction with Alternator Positioning, and the brackets mount to the Water Pump. Is your Pump pulley a C9- or a D0- If it is C9- you could switch out your Harmonic Balancer and Crank Pulley, and if it is D0- you will probably need a 70 Water Pump. IMHO, It is hard to tell in the pics, so this is just a diagnosis based on what I have heard. Does your Radiator Hose Flanges match the position of the water pump's? ie: Same Sides, Top and Bottom? Now I'm not sure if this is a 69 or a 70 motor, the 69 Orig. Water Pump is usually the determining factor, as that would usually be gone. .
To be honest, I am thinking this is the Orig. 1969 351W Motor for the car, and when it was 'Rebuilt' someone changed the Damper in the 1st place to a 70 Style. Is the car an Orig. 351W car? 'H' or 'M' as 5th Letter in VIN? If you still have the Starter Removed, what is the Date Code on Block, ie [8K23] or [9B6] or [0A15] in that format? 69 and 70 Balancers are different, the 70 sticks out farther. I'm not sure if they Weigh the same, but I think they do. I am pretty sure they can interchange. IMHO I still can't figure it out 100% since I am not actually standing in front of this car. Basically the Motor needs either a Completely 69 or a Completely 70 Front End. I recommend 69 Accessories. Just an opinion.
