Supercharger rebuild

[millyowner]

I'm pretty sure this is what PSE is doing. Paying $50 for cores, cleaning them up, then reselling them for two grand as "rebuilt."

Ya, I tend to agree. They just throw a coat of paint on there, but essentially just wash and re-sell.

If you read the paper that comes with the PSE supercharger they have a very interesting "priming" procedure which tells me there is no oil in the charger when shipped. If I was rebuilding a supercharger I'd probably put a little oil on my parts when re-assembling which would be enough for initial start. No oil and a priming procedure is more in line with them not being able to get in there in the first place. Just tearing it down as far as it will go and cleaning up the crap in there...

hrm. I never did send back my core, instead opting to pay the $250 and keep my original charger. I think I may have a new project when the weather gets a little warmer muhahahah

Great work!!! I think this will help us keep these cars going a little while longer

bov's i made 2 of they are going on a 1978 LB lancer with a 4g63 using a milly charger.

the 12 point nut is somewhere between 19 and 24mm it was a while ago that i did this but its just a regular 12point socket nothing fancy.

as for bearings they are roller bearings and ball bearings and there is no room to press them so they have to be carefully pulled out, i replaced 2 of mine
the first i tried to press and broke the seal the second i pulled and with more success
the bearings are set into the case and are a PITA to remove, ask you local bearing shop for some retaining bond when reinstalling new ones

Looks nice but I got stuck,got the two bolts of no prob but how did you remove the gears.

I was also thinking maybe we could use sealed ceramic bearings and not worry about oil seals.

so It's been almost a year since anyone has kicked this thread. I'm just wondering if any of the original posters are still getting email cc's about this thread and would care to come back and share their experience. at the very least some additional pictures if they don't want to reveal all their secrets.

also, in a somewhat related topic, I removed the pulley on my charger only to reveal the oil seal around the input shaft is leaking slightly. Does anyone know what a replacement P/N is for it. there is nothing in the Mazda EPC and trying to cross reference these **** oil seals seems to be a real PITA.

There are soooo many used superchargers on ebay these days, just checked right now, and there are 8 available from anywhere from 300 to 500 dollars. Several of them have 30 and 90 day warranty, and say they were pulled from a perfectly working car with no smoke.

It's almost not worth rebuilding one or buying one that is rebuilt. Probably better just taking a chance on ebay. Even if you get a bad one and then have to buy a second one, it still is way cheaper than a rebuild.

At between $1,600-$1,800 for a "rebuilt" supercharger, you could buy 4 or 5 ebay units. I'm sure that from a probability standpoint you would get a good one on ebay with those odds.

Now if you want to do a rebuild yourself, more from a project standpoint and learning experience, that's different. That's worth doing if you want to tinker around with one. But from a financial standpoint, it is probably not worth rebuilding with so many perfect condition used ones floating around.

Thanks mazda-fla

It was more just for my own curiosity of "how things work". I actually have a spare charger sitting on my shelf plus the one in my car is a PSE rebuild so no need personally for a new one. I was just curious...

this is what got me interested in this site

Im a newbie to this thread... but no newbie to the mazda motors. owned a 1991 probe GT, 1993 probe GT 2.5L engine, 1997 Mazda Millenia L 2.5L engine, and now I bought a 2000 Mazda Millenia S millennium edition i just picked up last friday.

I bought it for $800.00. guy said its got bad oil seals in the SC and doesnt wanna take on the project and has found out a new one cost $1,650.00. Im gonna buy one on ebay, so i have an extra SC in case my rebuild of this one leaking goes bad. however, im worried its probably more than a leaky seal in the sc. it was like SOLID smoke coming out of the exhaust when i first picked it up and i was able to drive it on the trailer and bring it home. this car is worth $4,400.00-$4,700.00 fixed up right now. so i think i got a good deal. body wise is not horrible but not excellent. I wil post pics of my car in a newbie or intro thread... not here to hijack either.


does anyone else have this experience? i mean it was SOLID smoking coming out... not like some see through smoke.. this was some heavy cigar smoker type. i did call mazda and a new full assembled engine is currently $6,400.00. im hoping its not something else this guy tried to hide from me.
