Yes, I considered in my case of pulling apart and fixing, but glad I didn't. Plus didn't make sense since under warranty. What's happening in our case is if you tighten + nut on rectifier, it loosens when you take off.Right?
I did a little research after my 4 alternator day experience.
What I found was reman (and icbw been probably 5 years) = blast clean and new bushings and brushes at a minimum. Windings, rectifier, voltage regulator don’t get replaced if they “pass” or work.
Of the 4 I had, in this order.
1. Worked great but had been dropped and one of the mounting ears was smushed and bolt wouldn’t go thru.
2.Just didn’t make power
3. Made power but the pulley wobbled like me after 10 Old Fashioneds at last weeks Christmas party.
4. Didn’t wobble but had very excessive lateral play in the shaft/bushings. Like a wore out ball joint!
The store, also a dist center for the Vancouver BC suburbs only had 4 remans and no new ones. (Reman was fcking $300 CDN iiirc as well)
After wearing a path in to the asphalt parking lot walking back into the store so many times with a broke out of the box alternator, I was out of options except to try a discount place like Princess Auto.
But was on a time line as doing it between sons morning and afternoon hockey games.
The counter staff lady was very accommodating and allowed me to “borrow” a new drill and drill bit off the shelf and the. Made me go outside around the corner to drill out the smushed hole on alt #1.
Got us on the road and I’m appreciative of their help. Despite the poor quality parts.
Anymore if I have the time and ability, I take components like starters and alternators to a local rebuild shop. They will replace everything or just what you want done. This doesn’t work in many locations because not many Indy shops that rebuild them anymore.
I talked to a guy who used to rebuild and he suggested that it's good I didn't, because they are not easy to get back together...
Your case sucked, but you got r done.
