Steps to change Alternator on diesel L300 Delica?

I ended up draining the oil just because it was time and and could get two birds stoned at once. I am having a heck of a time getting the hinge bolt out. Did anyone else have trouble with that?

Wiggle the alternator while pulling the bolt? It eventually came loose on mine... Just took some wrangling.
 
Mine seems a bit tighter because its not practical by hand. The alternator wiggles just fine but its the section in between the hinge points where it seems tight.
 
I had some WD40 I was using and seemed to help but I think I need to get something a bit more heavy duty. A buddy recommended PB B'laster. Its out far enough that the threads are no longer exposed on the other side, and that took minimal hammering and even that was on the bolt head's underside. The pry method I was using isn't as effective anymore as there is to much space between the contact points of my pry tool. My next thought is to create some kind of spacer. I attached a picture of the bolt.

Got'er swapped. That bolt just need to move a little more and then it started to loosen up a lot. PB B'laster is what I used for the penetrate. I tried a few different methods on the sticky hinge bolt, and what worked was putting a vice grip near the bolt head and then used a wrench to pry. The vice grip gave me a solid surface to get leverage, and wrenches are surprisingly good pry tools (better than the pry bar I had at least, and maybe only for this certain situation). Putting the new one in was cake but ended up having to get a new hinge bolt as the new alt's hinge point are slightly wider than the original. Not too wide that the spacer thingy (the ring inside one of the hinge point that gets pushed in as you tighten it) didn't fill that gap. I took the skid plate off too as that made it much easier to get to the lock and tension-er bolts.

I would definitely suggest replacing the small flex oil line on the back of the alternator. When mine failed 5 years ago there was a stream of oil all the way to the auto parts store. So if yours is original I would definitely replace it ASAP!

Thats a good idea! Where did you find the replacement flex line at? Or do you have a part number?
 
I got mine at rising sun imports near Vancouver Canada. Coombs country auto on Vancouver island is also a good source of parts. I guess it all depends on price and shipping. They both are quality delica shops!
 
I found this on Coombs country auto website. Rising sun definitely has everything delica but don’t have all their parts listed.

The swap out was not too bad. The biggest issue for me, was that in order to replace the alternator, you have to change the oil. Which is "weird" to me!

But after you drain the oil, it's just a few bolts to loosen to get the belts off, then take off the connectors from the alternator (both oil and electrical) and then remove the bolts holding it on.

I did the majority of the work underneath the car, so make sure your are on good jack stands/ramps, have your rear tires wedged/chocked, and have a decent creeper to glide around on.

Hi there! Amazing job!

What alternator did you get, seems we ahave the same Delica L300 1992 satarwagon super exceed P35w

I found one that is $1200!?!?!

Thanks
 
I was going to change my alternator over the weekend but discovered that it was flooded with oil from a newly discovered ruined turbo. I plan to replace both now. Do you know of a new turbo I should use? preferably from Amazon?

Don't be so quick to throw the turbo away, a turbo that leaks oil isn't necessarily faulty. Check the shaft for play (lots of videos on youtube). Oil leaks can come from a few places on a turbo: there's a pressure oil feed on top, the banjo bolt seals might be leaking, or it might be the drain pipe below: the rubber hose can split. A tired, high-mileage engine will pass a lot of oil through the turbo's intake side too, check for oil in the intake pipes upstream of the turbo.

More serious is the oil feed to the alternator itself, the short flex pipe from the engine, if that splits you lose all your oil. The vacuum pump on the back of the alternator is full of engine oil, if one of the seals fails it can fill the alternator with oil too.

What? The turbo has nothing to do with the alternator... the only thing they share is the engine oil system (sump/supply).

My turbo leaks a little oil into the intake; excessive back pressure on the seals from what I can tell.

It appears the turbo is spraying oil over the alternator. Not sure how because I haven't pulled anything out yet to check and I am not very mechanically adept so it will be an extra fun process for me. Great learning opportunities ahead.

Thanks for this great information, might be easier to find repair parts than a while new turbo. I plan to get my hands real dirty this Sunday so hopefully I will be able to determine the issue from there.
