Ok my first real wrench turning here. Put a new water pump on a 352. I put the thing in alright, but I went to put the alternator in its place and the belt shrank, at least that is what I am sticking to.

Has anyone had to put a bigger belt on when changing water pumps?

 

Somethings not right the alternator will swing 3'' they belt can not be that short. Are you sure the alternator brackets went back on the pump in the correct order???

 

I feel confident I got them right and looking at some books for pics to ensure I did put them on right. I tried to force it, lol, but wasnt gonna happen. I got swing but still cant figure it out!

 

If memory serves, the pump pulley is swapped, so same back right?

You didn't change anything on the alt. you didn't have another belt out for any reason just comparing something??????

Everything that was removed was re-installed with one exception...the waterpump.

What year did the autoparts store sell you the waterpump for? 1958/76 FE engines: There are 3 different waterpumps.

1) 1963/64 Thunderbird / 1965/71 Passenger Cars / 1965/76 F100/350.

2) 1964 full sized Ford/Mercury Passenger Cars (a one year only pump).

3) 1958/63 Passenger Cars except as noted above.

You may have unknowingly installed a 1964 or earlier pump. While it bolts on, there are differences. 1958/64 passenger cars (except '63/64 T-Birds) came with generators.

First year for alternators in everything (except 1963/64 T-Bird's which had it first) = 1965.

Do you stll have the old pump? Compare it with the replacement to see if they match...exactly.

 

Being excited I figured out my mistake, and did it after a break looking at hot girls posing with old hot rod cars lol.

I always keep the old part, as I have learned that you can learn a lot from the marks left on them and the clean spots where dirt didnt get to. So after an hour I went out, studied the old water pump, and saw I had put the top bracket in a hole, that was on the original and replacement, but NOT used . So a few fast wrench turns and it was all good.

Talk about a learning experience. I had learned several things, like dont be so excited you cant pay attention to what your doing!

Thanks for all the help and the water pump info!

 

Yeah right, blame it on the girls.

It happens to all us us at least once. A couple of years ago I replaced the timing set in my 410. Being in a fully loaded Park Lane should give you an idea how much stuff is attached to the front of the engine. After getting it all off I put the new set in. Had everything painted fresh. New water pump, hoses and so forth. Put all the brackets and accessories back on and started the engine. Lasted a whole 10 seconds with all the scrapping I heard and turned it off. Knew it was the timing set and stood there to ponder the situation. Then I realized my mistake. I put in a double roller set and kept the washer in that was behind the old set. Duh, you remove it and get rid of it. So I have to take the whooooooooole thing all apart to remove the washer along with releasing pressure on the rocker shafts to get the cam in it's right place. Problem solved plus I am real fast at doing this type of thing now...

 

See, I figured maybe you had gotten some Tide on it.

My wife uses that stuff in our washing machine and it has been causing my pants to shrink for some time now. Come to think of it, I been needing a bigger belt size as well!

Looked at my old 390 pump & brackets in my garage floor yesterday, I can see how it could happen.
