5Ton ALT. DILEMMA!!(PICS)

[No.2Diesel]

Hi,

Maybe you 5ton owners can share your input on this...Purchased a rebuilt alternator from CME Armature (took forever) to replace the existing one that doesn't charge due to always running on dead batteries from the previous owners.

The NSN (2920-00-909-2483) and the Mil Spec # (MIL-G-46795E(AT)) are the same for both the old and new unit. The problem lies with the shape of the front face of the units case. They are not the same and I can't swap the aluminum fan and pulley from the old unit to the new one.

The old alt. case has a stepped front face and the fan blades follow this contour. The new unit has a completely flat front face and the fan would contact the case if installed. Its not a matter of adding washers due to the fact that the shaft is not long enough to accomodate them. Otherwise the mounting ears and other things appear to be the same.

If someone out there in MV world has an aluminum fan and a matching pulley that goes with a flat faced 5ton alternator, contact me as I need one pronto. Thank you for your time.

Here are some pictures to better illustrate the problem.

The fan is internal on the replacement alternator. We figured this out at Aberdeen when we replaced the alternator on CGarbees ride. AM General can conrifm this too.

who replaced the alt on cgarbiees truck? We? I think I had to get my little lunch hooks in there lol But really Kenny is right the new style is a tad different but work just as good. I have the newer style on my deuce and 5 ton.

At least it wasnt OCD-boy who had the square out, making sure the lettering on my freeze plug was straight!

Westy is right. The pulley replacement was more of a group discussion. Westy mounted the fender. Sorry Rich.

Beggars can't be chooosy. I don't think anyone saw you up on that fender putting in the freeze plug.

Your answer is to just mount the pulley on your CME Arma rebuild and away you go... save all the old stuff as the cores are worth some money....

Thats just your basic US GI 60 amp generator. Nothing 5 ton specific about it. The older humvees and M35A2's use them also.

If there ever was one word (not sure if its an actual word) to describe my thoughts right now... DUH!!!

I was looking at the internal fan many times point blank range. Block head syndrom again. Thank you ACE, Recovery and others for your help.

You just reuse the pulley from the old alt. The newer one is just the more modern replacement, however, they been around awhile too. Change out about ten of them so for.

I know I'm drifting off topic a bit but that first step off the back of a deuce is hell in the middle of the night when you gotta take a leak. Just thought I'd share that. Back to your regularly scheduled alternator discussion.
