New OEM Alternator price? (1 Viewer)

[igotta40]

I’ve been using the aftermarket alternators from the local O’Reilly/Autozone for a long time but the last few years have been seeing them with incorrect pulleys- narrower, smaller diameter. Anyone else seeing this? How much is Toyota charging (pardon the pun) for a new Nippondenso 45 amp one? I have a 1974 FJ40 I bought used in 1980. I don’t want to get too far away from stock. What about Rock Auto?

Toyota is charging zero dollars.

They are discontinued. Haven’t been available in over a decade.

Why not just swap the pulley?

 

[igotta40]

The pulleys are on like nothing I’ve ever dealt with, it’s as if they are welded. I don’t get it. I may just take my bad one to a shop.

I replaced the brushes in my ‘74 original alternator to fix it, worked for years until I swapped to a 90amp internally regulated 12SI GM alternator to better keep up with winching. Perhaps yours is also repairable

I also replaced the brushes… not too hard to do really

Did you use an impact wrench?

Did you use an impact wrench?

x2 and give a squirt of pb blaster

 

[igotta40]

No, I used PBBlaster and cheater bars. No go. Instead of dealing with all that, I dropped it off at Pearland Alternator this morning. They
said it has a bad diode. So pulling it all apart and replacing brushes wouldn’t have helped. I appreciate all the suggestions.

Full rebuild?

 

[igotta40]

As far as a I know, yes. I’ve been taking starters & alternators to them for over 30 years. Never had a problem.
