Supercharger whoops!
Today the bits of metal I ordered to make up a frame to rest my supercharger in the hydraulic press turned up. Great I thought, I can finally get on
with the rebuild.
So, I merrily cut up the metal bars and set the 'charger up in the press ready to push out the rotors. Bit of pressure, nothing moving.... bit
more pressure, nothing, little more and crack.
Now, I'm no expert on superchargers, but I don't think this is going to work again:
 
supercharger broken
So, question is, what do I do now?
The supercharger is a TRD unit designed as a direct bolt-on fitment to US spec Toyota Camrys. They're very difficult to come by and fetch big
money, especially on this site of the pond, so finding another 'for parts' isn't going to happen. But, it's well known that
it's an Eaton M62 unit in a custom housing that fits in place of the inlet manifold.
Now, that said, as it's an 'M62' will the rotor pack and (more importantly) the alloy plate be the same in all M62's? In
other words, if I buy a replacement unit from a Mercedes which are a lot easier to come by will I be able to swap the internals over?
Any other clues as to how to solve this problem appreciated. I won't say how much I paid for this very rare bit of kit, or how long I was
looking before I found this one, but lets just say I'll be gutted if it's a dead loss!

what about chemical metal or drilling an tapping a load of fixing and some sealer as i guess thats not a structural mounting but more a inlet flange

Is it possible this is the same blower used on the Previa vans? If so one close to me is going to the wreckers on Saturday

Ouch, I feel the pain!
Of interest will it come apart, or is it still all stuck togeter?
If it can be dissassembled, can the case be tigged and skimmed?
Sorry, not got any other bright ideas,..

I reckon it's Tiggy time personally though it would depend on the alloy used.

You need to get on the blower (sorry) to someone who refurbs the M62 and ask them, and possibly cross-reference part numbers. I'd also be
looking at geting that casing repaired, even if it means getting it TIG welded and then milled back to size. Good luck.

if they are that rare then v it up on the inside tig it round then re machine it. almost anything can be fixed it just depends if its an economical
repair or not

Ouch !
Time to TIG, it looks like you have plenty of room around the gears to add a fillet on the inside, the rotors are supported each end and aligned by
the body so not a scrap item yet and hopefully no need to machine either.
While it’s in parts you can port for extra oomph, I got good gains on mine by modifying the inlet and outlet to copy a Gen5 Eaton.
I have an AC TIG, but have not done ali for a couple of years but happy to give it a go, may be a bit agricultural.

The cracked part looks like a standard eaton component. There are a couple of companies that do superchargers based around eaton units and it is
normally only the main housing that they custom manufacture.
Replace the fractured part. If you weld it you will end up with distortion and remove the heat treatment. Might be OK but why take the risk. If the
rotors touch each other or the housing you scrap it.
If at first you don't succeed, hide all evidence you ever tried!

Martin Keenan at MK Engineering would weld that up no problem.
I assume from your post that it doesn't matter about other rotors as it's the housing that's custom?

This is basically what I was asking really. Yes, I know it could be TIG'd, but I'd prefer to replace if possible.
If the 'M62' bit is the rotors and the top plate then I can (hopefully) just swap it over. The rotors really needed re-coating anyway so
it's not the absolute end of the world.
I guess what I need is someone who rebuilds these things for a living that I can take all the bits too and see if I can match it up to anything.
Yes, worst case it will TIG up, but it will need to be done very accurately. If the bearings in this plate are out of alignment with the ones at the
bottom all sorts of nasty stuff will happen.
Cheers, Chris

Yes, realised reference alignment problem later.
Sorry I see you mean the main housing is custom but this is an endplate.
I had a similar problem when a customer had a blocked oil feed line causing bearing seizure, so bad it stopped the engine and it wouldn't turn
over at all on starter. Endplate was scored deep but had it welded up and skimmed accurately.

Talk to Roger Clarke here in Reading.
He's an ace welder to the point of being anally retentive in his perfection.

pretty sure its a generic part as the difference between m45 and m62 is rotor length not diameter ,i had the part you need from my trashed m45 but
sods law it went in the scrap bin a couple of weeks back

Need to start looking for pics of M62's disassembled I guess and see if it looks the same. That's the ideal scenario in my book as the
rotors I have are not in the best nick - see my previous thread, some of the coating has worn off.
But yes, I accept, welding it could probably be done if it came to it. The only problem is that I can't get the rotors out, and now I
can't press it either as I'll just damage the housing even more.

Does anyone know of a (preferably local) supercharger rebuild company/person to take this mess to for some advice? I'm near Aylesbury,
Buckinghamshire.
I'm sure there was one in Langley (near Uxbridge), or close by there, but can't find it now!

Hi Chris,
I would just get another blower if i was you. what engine are you putting it on? have your already made the required mountings / pulley's?
If not go for the most common blower, M90.

Have read it again! you have a V6 in an MR2, the blower you have was designed to fit the V6.
Have i got it right?
I would say you are better off modifying the installation to take a common blower, i dont know what size the V6 is but the M62 is only big enough for
a 2L engine UNLESS you are only planning to use very low boost, to make the whole thing worth while you need design an install that is capable of
decent power. It is FAR better to underdrive a blower than overdrive it, so the bigger blower is the way to go. M90.
It looks to me your blower is scrap, so now's your change to upgrade. Do it properly, do it once.

Just an update on this. First off I finally managed to get an account on the forum that was recommended, although it wasn't much help in the
end.
However, I have discovered that the BMW Mini M45 supercharger PROBABLY shares the bearing plate (the bit I broke) with the M62. The only difference
is the length of the rotors and of course the housing, all the other dimensions are the same.
So, my plan is to buy an M45 and raid it for the broken part. Obviously these are far easier to come by in the UK than an M62, and therefore
considerably cheaper.
I say 'probably' because all I've been able to do so far is compare photographs and dimensions. Everything matches up so far but
until I get the two parts together I won't know for sure. Will update as/when that happens.
Cheers, Chris
