squirrel in alternator

it's getting worse and worse, it started a week ago when there was this squeeling from the motor. Thought it's the idler pulley, sure not, It's the alternator. Is there a way to give it a little more life? My bank is not ready for a replacement....

Take it off and blow it out try to clean it up. Might help the alternator . I pulled my starter apart and cleaned it up and man did it start better

if your mechanical you can pull it apart and replace the bearings and brushes .
it is not to hard to do and a lot cheaper then replacing it.

after you have the cases split you will use a socket the same size as the outer race of the bearing and tap them out with light taps from a hammer on the socket. take the bearing to a bearing store match the numbers take them home put them in the freezer for about 3-4 hours to let them shrink a bit and then use the socket again to tap in the new ones.

Hey Chief funny you said that. My dad was a helicopter mechanic at sheppard airforce base and he taught me the socket trick while teaching me how to work on my motorcycles.

Gampmx most likely you will find that only the frt. bearing ( behind the cooling fan ) will need replaced. It is the one that is under the most stress load of the belt and the one that tends to get grit behind the seal and into the balls.
You can gently pry the seal off the bearing and flush the old grease and dirt out with something like carb. cleaner and then repack the bearing with high temp water proof bearing grease then replace the seal and reinstall the bearing . This works well enough a lot of times but i only would do that if you can not find a new bearing to put in.

I called the standard places today like AutoZone and so, nothing. Luckily one guy mentioned a local shop and I called them, they have it all in stock. DB Electrical Starter-Alternator I was also looking at high output (200-220 Amps) they have some for $200 new. Not green but half the price ;-)

yep you can add high output windings and make your own green if you want and save some green.
And use that saved money to buy a gear reduction starter and have the best of both worlds.

I shot the b... last night. It's a ND alternator, got the front bearing out but not the rear. Darn rotor will not come loose. got me the bearing today $12 and I will put it in tonight. The alternator shop will test tomorrow. Hopefully I just killed the squirrel and not the darn alternator.

alright, the freezer trick was great. worked perfect, everything asembled and no parts left. (that's a new one) I will see tomorrow.
Scott, how do you add high output windings?

You would get a high output stator from the alternator shop if they make one for the one you have or see if the shop your dealing with can rewind it.
