The old Valeo alternator died yesterday and after reading the earlier threads decided to try the Delco conversion.

The local Autozone listed the 1988 Camaro 2.8L as a Duralast unit but when we opened the box the alternator housing was stamped Delco Remy. It looks exactly like the CS-130 pictured in the earlier threads. They even had the pigtail connector.

A few hours and some minor electrical and mechanical mods later she fired up with a rock steady 14V.

The car never had a steady voltage before, the needle was always a bit twitchy. Now it is beautifully steady.

My thanks to all those who posted their experiences with this mod. I would never have been able to do this without your help.

 

Just curious -- do you have the ribbed belt? What diameter pulleys? The biggest obstacle for me was the rotor speed on the alt. -- couldn't get the fancy CS130D to spin fast enough.

 

First of all I used the CS-130 not the CS-130D. I'm really not sure what the difference between the two is but the earlier posts seemed to indicate the CS-130 worked better at low RPM.

The pulley that came with it was ribbed but was too wide. It was also slightly larger in diameter, about 56mm at the ribs, didn't measure the original pulley. The shaft diameter was the same so I just swapped the pulleys. The Delco does not have a keyed shaft so we had to really tighten the nut. It also took some time to come up with the correct arrangement of washers as the original pulley will bend the fan back against the housing. You need a pretty thick washer between the fan and the pulley.

The only other problem was the tensioner mount. The Delco ear is not as deep as the original and the hole is threaded. The thread is the same as the original tensioner attachment (8mm 1.25 thread).
I used a die on the original, threaded the entire length and screwed it into the Delco ear. Didn't want to cut it shorter in case I needed to put a Bosch alternator in at some later date.

Other than that, no problem (so far, knock wood, etc).

 

Damn, Thanks Phil!!! I was just contemplating doing this myself. How much was the Delco CS-130?

 

The alternator was $74.99, Duralast DL1342-6-11 and the pigtail was about $6.50, Conduct-Tite part number 85854. You will probably need help getting the pulley off the Delco. We used a long handle on the allen socket, a deep offset box wrench, and some choice words.

 

OK, Thanks Phil. Yep, I have all those tools. Have a whole toolbox FULL of those choice words. Thanks again.

 

Duralast is just a label on the box that Autozone uses. The alternator is a rebuilt unit, and probably rebuilt by the same company that does rebuilds for countless other retailers. That's how the industry works. With few exceptions, most replacement parts are rebuilt.
