Thread: Alternator bracket question,,

Tweet

I have a 1984/5.0 in my 54 wagon and and I got rid of the original serpentine brackets,,,,I have found the right 2 groove pulleys that will work and i'm using a Allen Grove air conditioning bracket on the passanger side,,,,,

I am looking for a bracket to mount the alternator on the drivers side,,,,

BTW,,,,I have changed the water pump to a regular style,,so that problem is already solved,,,,HRP

I have the alternator on the right side in my pickup, 351W engine. I just fabbed my own brackets and used a 3/8 ID pice of tubing to space it out on the head. There's a pic of the engine in my gallery.

As Dave S. has said, space out from the head, there are usually two bolt holes there, one of which is 7/16 - use that one. Use an ARP or at a minimum a grade 8 bolt - the alternator hangs on it. You can buy an adjusting bracket from Summit or Jegs or, better yet, take a walk in your local junkyard and find something that looks close. It will need to be bolted to a water pump fastener. You might even find a real 302/351/5.0/5.8 bracket from some vehicle that will work, heads are a mirror image as far as bolting and bracketing.

A temporary spacer that I once made up for a dressed out engine was cut from a piece of chrome water feed pipe from Home Depot. tho the final one ended up aluminum(from a 302)

yup, i've made brackets before to locate them on the upper mounting pount for the powersteering using the two holes on the water pump and the head... you can also mount it down below the crank pulley as were some powersteering pumps

The 80s crown vics have the alternator on the drivers side but the bracket is a big aluminum piece that also has the mount for the P/S pump,it possibly could be trimmed down some if P/S is not being used. Jeff

Here's an easy to make bracket.

Use 1/4" x 1" aluminum for the straight pieces.

1" aluminum round stock drilled for the bolt and length to suit.

Most times you can adapt a chrome adjuster arm from the parts houses with little to no trouble.

Here's another one.

This works well with heads that have 3 accessory bolt holes.
Constructed of 1/4" plate and 1" round for the spacers.

Both alternator mounts shown are on a 455 Buick engine.

The 3/8" stainless steady rod may look a little strange.

I have an identical alternator mount on my 32 roadster, 44,000 miles with no problems.

This makes a very steady mount.

The 2 bolt mount shown above is also very sturdy and should work well on a head that has only 2 accessory bolt holes.
Trick with the 2 bolt mount is to get the adjuster arm out far enough that it's a part of the mount system and not simply a locater for the alternator.

My alternator is also on the driver side of my car. I am working on my interior right now and just got on the computer I will take some pics of my bracket and post em.

Always room for another alternative alternator bracket,,,a photo would be great. HRP

I used a 3G from a late model Taurus so I could get 130 amps and 14.4 at idle from a single wire alt.



The pile of parts. I fabbed the upper bracket and the adjuster is circa 71 pickup. The cast piece on the head is also 70's pickup.
