School me on 6 cylinder alternators Options

[tornik550]

I am in the market for a new alternator for my 2.7l. I currently have a SEV Marchal. It is not working. The fan housing that I have is from a 2.2e. Any recommendations of an alternator that I can install? I know very little about alternators on 6 cylinders. Any advice is much appreciated. Cheap and reliable is a major plus.

The 2.0 to early non internal reg 2.7 housings are the same depth. The later 2.7 internal reg housing are different for sure. I came across this a few years ago while doing my 77 2.7 rebuild. The late 2.7 are the same as the 3.0 housings but different part #'s. The 3.2 housings are different from the 3.0 units. I've had all of the above in hand so I know they're all different.

I went with the external reg version just to simplify things. Also if the reg craps out its an easy swap in a 914. If you have an internal reg unit and you have a problem you'll have to remove the induction, fan shroud, alt/fan housing to remove the alt.. In a 911 it's not bad as you're looking right at the fan but the 914 firewall is your enemy.

Most alt repair shops can rebuild your alt but bring your voltage reg with you so they can test that too.. IIRC my early non reg alt was around $150 to have rebuilt.

Now whatever you do take caution removing the alt from the housing. The mag housings will crack if you're not careful . The best way to remove the alt is to place some heavy cardboard on the floor, use two 4x4 pieces of wood (place so the housing lands on most of the wood but clears the alt) then from about a foot or two drop it on the 4x4. the alt should pop right out. It doesn't sound nice and I know I said be careful but this is the way to do it. Check the Pelican site this method is what they recommend for the alt/fan housing separation.
