HOW TO : Replace Worn Alternator Brushes (not charging)

After buying 3 alternators in 2 years for my old 4D56 Pajero which all failed due to 4wd-ing in mud, I decided to start rebuilding them. This one is off my 4M40 Pajero but most vehicle alternators are the same basic design. This one is a Bosch unit.

Great video. Word to the wise- these steps are likely good for most alternators, but if you are working on an AC Delco AKA Delcotron alternator NEVER use an impact gun to install the main hub nut. Doing so will distort the body and cause rubbing... I had a parts store fellow think he was doing me a favor by installing the nut on my replacement (when I only asked him to remove the old one). He handed me a fresh, but now broken alternator. I was stuck in that town for another 3 days while another unit was sourced. Thanks for sharing. Love those Pajeros- we own two 1990s with 6G72 here in the USA we call them Montero, because Pajero means something bad in Spanish slang. Cheers!

Good info there. Luckily I’ve never worked on that style of alternator. Good to know though.
