I have to replace the alternator in my 91 Terrano. Damn things draining the battery and I think the bearings gone. Anyway it turns out its the same alternator as fitted to a 91 Navara and the TD42 patrol. Does anyone have an idea about what is a good price for a second hand one or what i should pay for a new one.
I believe its a common fault for the alternator to fail on the patrol, therefore on the Navara and Terrano also. Given this, what are my chances of getting a half decent one from a wrecker? Or should I buy new? I have found a secondhand one in Lismore ( wherever that is ) for $330. Anyone have a spare one lying around?
Also there are two pipes connected to the back of it which I have been told contain engine oil. Is this correct and will they cause much drama when I go to replace it.
I mean will I have to drain the oil or just plug the pipes while I swap them over?
Thanks for your help
Jim

I would get the alternator serviced and then re-installed. I’m sure that this would be less than $300 and you would know you are ending up with a unit that is good as new. Any good auto elec should be able to do the job.
There is a vacuum pump on the back of the alternator, which assists the brakes, this is why a replacement is so expensive.
If there is nothing wrong with the vacuum pump you don’t have to replace it, just unbolt it and have the alternator serviced and re install it. And yes, it does contain oil. About 5ml according to the Terrano II manual.

I just had a look at the manual and the vacuum pump is just attached by 3 bolts for the Hitachi model or 1 bolt into the end of the shaft on the Bosch alternator (assuming a '91 is similar). So you might be able to remove the alternator without disconnecting the pump from the brake system.
