alternator relocation

Post by Gentleman Rogue »

im lazy and just copied this from Jeremy's site; enjoy!

so i'd really like to keep powersteering in my truck, but the placement of the powersteering pump above the alternator would put it too much in the way of all the piping off the turbo, which is why most guys do without powersteering i would assume.

i got the idea that if i could relocate the alternator to the driver's side of the engine, i could clear up a lot of space on the cluttered side of the engine. a quick search of the internet yielded three things;

1. Buschur Racing kit- $180-

2. Jay Racing kit - $120-

and 3; a homemade bracket by a member on some DSM forum that looked like absolute hell. it was made from the stock A/C compressor brace and a chopped up powersteering pump brace-

as bad as the homemade mount looked, the price tag of the other two options looked even worse. i decided the worst part of the homemade mount was chopped up brace, but the idea of utilizing a strong cast mount sounded good, so i set about finding a better way to mount the alternator to the old A/C brace. after my grandfather and i brainstormed for a bit, we came up with an idea, and tonight, set about making it happen. here is the initial mock-up-

basically all you need to do this is a around 10"-12" of 1/4" thick angle iron, some time, and some way to grind metal(bench grinder, belt sander, etc). first, on the bottom two bolt holes that bolt the compressor to the brace, cut off the "ears" that protrude out, and grind the face of the bolt holes flat. measure and drill two holes to bolt 9" or so of the angle iron. out of the excess, cut two brackets about 1" wide each. drill holes in the brackets, and grind corners round so they'll clear the alternator as it pivots. run a bolt through the alternator with the brackets on the inside of the flanges(see pic). i cut a little sleeve to keep everything square to tack everything together.

the other modification to the brace is grinding the upper arm(that sits up by the timing cover even(as-cast, its thicker on one end) so the tensioner will bolt squarely(flat) to the brace. this will help locate everything, and as luck would have it, lines everything up pretty well actually.

i have it bolted in the truck now to mock everything up, and all looks pretty well so far. hopefully i'll get a chance to weld it up this weekend. i'll hopefully have an update with some pics in the next few days. enjoy!

good job man! i ended up buying the setup from jay racing on ebay for 60 shipped (used). it does the job but i do question the sturdiness, yours on the other hand looks nice and solid

looks good mate! what do you plan on doing about a belt for it or will the stock one still fit?

you should be able to select a belt from a catalouge fairly easily as they are only made to standard lengths.

theoretically you could even solid mount the alternator and use the factor 4g63t a/c tensioner setup to tension the belt, its even more weight, but its a failproof setup.


also, nice design, i may have to end up doing that on mine.

i really liked the idea of getting rid of the A/C's tensioner(didnt want it to chew my timing cover up anymore), and i dont think you could get the waterpump pulley on deep enough to use the inner groove on the crank pulley.

Dead thread revival. Thanks a lot Gentleman Rouge, I do happen to have a Power steering bracket and a need for the alternator to be on the opposite side from stock. Thanks for this post

I needed to make room on the passenger side of my engine for the new turbo, and it was a balmy 40 degrees out yesterday, so...... I moved my alternator with some custom bracketry. Yay.

Nice Job... thats about what I was in the middle of designing when I found that I lucked out with only a 40" belt and the stock location to get my belt tight and clear the turbo intake and coolant hose.
I will probably still end up relocating in the end tho, just not today.
