Grand Master B:
So i finally stole the virginity on my Wrangler. However - i think i may have hooped my alternator. Does mud typically screw up a guys alternator? I thought these things were made for the mud and dirt? Anyhoo - is it easy to rebuild an alternator? How much does a new one run for a 2.5 L?

Any help would be much appreciated.

All you have to do is take your alt. apart and clean it out with gas or solvent. Not thinner though cause that will take the insulation off the coils. After cleaning ......inspect all the parts bearings,brushes,regulator...ect. Spin the rotor slip rings (copper)with a  peice of scotch brite to remove and carbon build up


replace parts as needed ....(canadian alternator and starter)
assemble and put it in the jeep

run the engine for 5 min or so with no load(big stereo, lights) to seat the brushes on the slip rings. This will make sure you do not arc or pit the slip rings from poorly seated brushes

once your that far you might as well replace bearing and the brushes.




k good luck

Grand Master B:
Awesome - thanks!

CJ-7:

We have hi amp (140 Amp) units for your Jeep, plus all the high quality components (no chinese parts sold at our place)  to rebuild your existing unit, plus we've been in business for 20 years, so we've learnt a few things.  Watch our web site for upcoming DIY rebuilding info.  Also, part of the procedes of our sales to the 4x4 community go towards the trail fund.  Support those who support your sport.

Oh by the way, do not under any circumstances use gasoline to clean your alternator unless you want to have an explosion inside the unit. We've had this happen in our shop when a customer brought his alternator in because it wasn't working. He had tried to fix it and couldn't so we ended up with it.  It blew up right on our test bench, causing damage to the unit and also the technician working on it.
