dori's 1mzfe M62 blower rebuild help request thread

[dorifuto.boi]

hey guys,

i just wanted to start this thread to get some help so that i can rebuild a supercharger and put it on my car.

if i may, i wish to link eye8pussies's build thread for reference if anybody wishes to rebuild their supercharger as well.

i want to start off by saying that used supercharger oil smells like ish. im sorry everybody who lives on my floor (dorm) that i stunk up the whole floor. lol.

first of all, do you guys have any ideas on how i can get the pulley off so i can disassemble the snout ? i can't seem to find a way to unscrew the nut while keeping the shaft still.



second, are there supposed to be oil on the rotors ? there are oil on the rotors and its dripping out the manifold. do i have a bad seal or something ?

also, i heard that there is a coating on the rotors. so how do i go about cleaning off all the oil and debris thats on the rotors ?

theres no coating on the housing so i can just clean it with intake/tb cleaner right ?




the rotors don't seem too scratched up so i think the rotors will be ok. the casing however is kinda scuffed inside. should i just leave it as is or should i send it to a shop to polish it up ?

this is it so far. i'll keep this updated.

thanks a lot,
david

Errrr.... TRD blower = M62. I would have bought a M90 for a custom fab project if i was you! or wait. Is that a TRD charger?

Anyways, there shouldn't be oil on the rotors, IIRC. That's about all the help I can offer.

edit: My parents went to Purdue, and my sister will most likely be there next year. Go figure!

[bigbird]

what exactly are your rebuilding? are you just giving it a taredown and cleaning?

I have never rebuilt the TRD one. from what i've read, i dont want to. a pro is all i will trust with that task. but im talking recoating, replacing nose gears and such.

there should NOT be that much oil in there. now question? is that SC oil? or oil comming up from the intake manifold?

Put the blower back together. The snout pulley should have come off first. Once the blower is back together feed a folded up rag into the rotors as you turn the nut on the snout. The rag should bind the rotors enough to break the nut loose and a rag should not damage the rotors. That's the way we used to do it on Detroit Diesel blowers.

@LynchburgCSI
yea haha its a trd m62. i randomly picked up one with unknown history.
how come you know im at purdue ? lol scary bro.

@bigbird
well here is my plan since the history is known on this supercharger. i wanted to drain the oil and pull it apart and see if the rotors were busted and if the case was badly scratched by the rotors. if so, then i would ask a shop what they could do for me. if not, then i was just going to buy one of those "rebuild kits", clean up the snout, replace all the parts from the "rebuild kit" then put it back together and see how well it runs on my car.

now the rotors seem fine but its covered with oil which lynch said that there shouldn't be any. so im just wondering how i can clean up some of that oil before i put it back together. im not sure if its supercharger oil or oil from the pcv line. is there a good way i can tell ?

@Pvt-Public
thanks, will give it a shot

The website in your sig.

Gives it away haha

[bigbird]

no, there should not be any oil. what did the oil look like when ya poured it out? its eitehr burned oil that has been leaking on it from the SC or from the intake manifold.

[dorifuto.boi]

there was extremely little oil that poured out. it was black and smelled like ish.

[lemegacool]

yeahhh i just finished dissasembling a 16-17 years old m90 blower and GOD that smells!!!!! LOL

to clean the rotors i would use solvent and maybe rub them gently with a scotch brite


there should be no oil on the rotors : worn rotor pack seals (or crap from the engine, hard to tell but if you said it was smelling like ?&*%& then its probably SC oil), these are a bitch to replace as you have to completely dissasemble the rotor pack on a press. dissasembling is not hard if you have a press but putting it back together is another story since you have to precisely time the rotors since you removed the gears from them... i really hope it'll go well on my blower... if you do dissasemble the rotor pack then replace all the bearings (including the case needle bearings)

to unscrew the nut i used an impact wrench while holding the pulley with my hand.

to get the pulley off i used a press as it was on there TIGHT!

to get the shaft off the snout use a dead blow hammer of plastic hammer, it should not be too hard to whack out... again i used a press because i have acces to a couple lol

the rear snout bearing should come out with the shaft, then press the aluminium drive out with the bearing. i used a piece of aluminium pipe to whack the front bearing out, a socket with an extension on it could also be used i guess.


here is a picture of my completely dissasembled m90 eaton blower... yours should look like that but smaller

[Eye8Pussies]

a number of people have given good suggestions on how to take the pulley nut off, but I'm a big fan of the impact gun method- you can use a pulley puller to take the pulley off


as for the oil in the blower, there are two possibilities- either it is from the seal in the nose which is behind the coupler, which means that you are leaking synthetic s/c fluid and it will have to be fixed, or it may just be a build up of blow-by from the motor that it was on before

if it smells like total ass, then, unfortunately, it's probably the seal....which isn't something that can be easily tackled at home without the right equipment

[dorifuto.boi]

ok so heres the thing. i totally got a fever and am sick as hell and can't smell much but i tried my best:

i stuck my nose all up on the rotors and really couldn't smell anything. i stuck my nose in the intake manifold casing and couldn't smell anything. but when i stuck my nose up to the gears, i could smell that nasty oil. so i tihnk im just gonna conclude that the ish on the rotors is blow by and not the supercharger oil. (i think i said that the whole thing smelled like ish a few posts back cause when i took apart the charger, it made my whole room smell so bad so i coudlnt' really tell if the rotors smelled or not)

so lets just assume that the supercharger oil isn't leaking into the rotor pack. do you guys suggest i send the rotor pack to a shop anyways to have them check the rotor pack bearing/seal or should i just rebuild the snout and replace the needle bearings and call it a day ?

thanks a lot,
d

[Chris Crash]

If you've got the time and money, send it in NOW while it's all apart and off the car.

[bigbird]

you cant assume that, youve already said all ya need to. "very little oil came out, and it was black/ish". S/C oil is clear IIRC and well jsut smells bad period. your nose gears look to be in similar condition as your rotors which would tell me that this S/C has been running on low oil for a while. you need to get teh seal replaced to be safe.

[lemegacool]

well as chris said, if you have the money get it rebuilt now (rotor pack)...

if no then clean it up real good with scotch brite, rebuild the snout and replace rear needle bearings

and bigbird i think you are right... even my old ass SC oil in my m90 was more brown-ish than black

[dorifuto.boi]

ok thanks guys.

so im going to buy the kit and rebuild the snout.

since i have this supercharger apart and the history is unknown, you guys/common sense says that i should just replace the rotor pack bearing and the needle bearing in the back of the case. since the rotor pack needs to be timmed when pressing it back together, i think im gonna leave that to the shop cause i'll mess that up lol. as for the needle bearing, i don't even know how to get them out cause they don't have the little holes behind them that goes through the case. so i might have to ask the shop to do it...

so im just gonna clean up the rotor pack and intake manifold/case and then send those two out to get it rebuilt.

thanks for all the help,
david

EDIT: i just called PSE superchargers and they only do a full rebuild for 700usd. they won't do a partial rebuild. -sigh- i really don't have 700usd to spend haha
