Default M90 Rebuild Questions...*Update With Pics!!*

I want to buy this M90 from Ebay and rebuild it: http://cgi.ebay.com/ebaymotors/ws/eB...069386306&rd=1

1st, will it work on my 97? I'm thinking it should.

2nd, I looked for rebuild posts, finding none but posts that willwren did back on '03 with tons of parts and part numbers.

So I went to Google (sorry Will), and ZZP has this to offer:

http://www.zzperformance.com/grand_p...cdcb7fca3bb912

"Rebuilding your Eaton snout require a hydraulic press. Changing the seal on the end does not require any special tools. We do not offer tech support on these parts. We recommend that they be installed by a qualified professional.

Choosing the snout bearing option gets you the 2 bearings in the snout. The case needle bearings are a replacement for the bearings in the back of the case where the rotors slide into." From ZZP website

What do I need the hydraulic press for, the snout bearings?

My */C is making a little noise at idle. At 178K, I believe the coupler has seen it better days. So I went on Ebay and saw the */C (while looking for other things) and thought this would be fun to do.

All thoughts and / or suggestions are welcome

www.rollingperformance.com is cheaper (slightly), comes with the oil, and ships faster.

Sounds like that supercharger only needs a coupler, so why do a rebuild on something from an O1? That'* assuming you can believe the ad.

Why not buy the SC, verify the coupler problem, and do just that?

You need a press for both the nosedrive and the needle bearings. Talk to me before you do it. I'll have some tips/tricks. The nosedrive can be tricky, and the press depth of the needle bearings is somewhat critical.

Thanks Will. I will check with the hobby shop on base and see if they have a hydraulic press that I can use. They have everything else there

Greg...coupler is easy. I spy some work getting done if a second charger is involved.

I don't think I've ever weighed one by itself without packing material. I can tell you they cost about $30-$35 to ship coast to coast, UPS ground. All 3 I've purchased cost that to ship.
