Q: Series VI Rear Needle Bearing Removal?
Hey Fellow Saleen Owners! Recently Purchased a rebuild kit for my Series 6 Supercharger and am in the process of removing the rear needle bearings. It looks like they might be closed Back factory bearings? I removed the 2 Plugs behind the bearings in the housing but im afraid to press to0 hard on the back of the bearings if its not part of it. The replacement bearings in the picture look like open back bearings. Tried using a Blind Hole slide hammer puller but no luck. Do these just press out from the back? Thank you for any help!

No you can't knock it out from rear.
Took me awhile to work it out. Firstly you have to remove the needles out of the bearing to allow the puller to grip the shell I ended up making this tool which simplified the process. This way you do not damage anything. The alloy plate is 10mm thick I also made a special tool to press the new bearing in. Be aware the grease used in this bearing is harmful use caution and gloves when replacing them

Thank you for the reply I appreciate the info and the help! Nobody ive called will help with anything unless I have them do the whole supercharger. I’m stuck with the rebuild kit so I have no choice. I have pretty much that same collet puller but not the long screw shaft just a slide hammmer. I guess I’ll try to make something like that thank you! Looked like I could press them out after popping out those plugs. Glad I didn’t. Did you also replace your rotor pack bearings? Thanks again for your time it’s greatly appreciated!

I have wanted to pull this to pieces for sometime, you gave me the inspiration.
Not easy especially not damaging rotor pack or gears....but possible with right equipment. First remove the 3 pin coupling undoing the cap screws Next the 12 point nuts holding the gears to rotors these are loctited on so a little heat may be needed. I managed to get one with no heat. Thankfully I have a hydraulic 2 leg puller which I was able to get large gear off rotor. Then pushed the rotor out. That then enabled me to get the other gear off rotor using hydraulic press. Then pushed that rotor out of housing. I marked the housing with a 3 making sure the 3 vane rotor went back into the correct position. Tony

Tony thank you so much!! Wow you are the man for posting these pics! Probably the best shots of these I have seen on the net! Absolutely helps being able to see how it all is pieced together. I have all the press equipment and pullers and access to snap on for any special tools at work. I successfully rebuilt the front snout today! My next question is what is your plan to realign the gears and rotors? I was figuring marking the gears together and the rotors to the back of the housing. Did you mark them? Also noticed there is Allen holes in the rear of the rotors, maybe for a special tool to keep them aligned? Thank you again, I believe having this info out there for some of us able to wrench on our own cars if great and impossible to find. Thanks for sharing buddy! Here is a few pics of the Rotor Pack Bearing Part Numbers. I got them from John Bond Performance at a decent price! https://jonbondperformance.com/index...roducts_id=171

Don't use a slide hammer, you may crack or break the thin supports. This is aluminum and breaks easily. I would just clean those bearings and repack them with proper grease. They are not easy to R&R and you likely have to devise some special tools to safely remove and then press them back in. Have a look here: https://saleenforums.soec.org/showth...458#post146458

Lenko, thank you for the comment and advice! Unfortunately I already tried to remove one so I have to replace them now. My car has 105k so Its probably not a bad Idea to change them anyway. I think I know how to get them out now I just need to fab up the puller. Thanks for helping!

Ok here’s an update. I want to try and get as much info out as I can for future use for anyone and I hope it helps. I know many think I’m probably an idiot for trying to do any of this but regardless if I screw it up at least I learned something and we get some good info from it. I would like to learn so I can rely on myself to repair it in the future :)
So, I successfully installed the rear needle bearings using advice from the previous posts thank you! I removed them with a blind hole expanding collet puller piece attached to a threaded rod cut to fit the length of the case I got at Home Depot. Put the rod through a brace from another puller I had and treaded a nut and washer onto it. They came out no problem. Note that I measured the bearings were originally installed about 1mm below the top of the bore. They can go deeper. I re installed them at that depth. I used a hydraulic press and some sockets/extensions and lightly lubed the bearings. Long story short, it was very easy and not at all as scary as it seems if you just go slow and are careful. However now I do have a loud knocking noise from the blower and what feels like excessive lash or play back and forth if I spin the snout side to side. It clunks. I’m guessing it must be the rotor pack bearings. Everything else is new. I did install a new coupler supplied by Jon Bond Performance but it sounds more then that. Maybe I’ll try try the original. Do these have any lash in the gears? And does anyone know the spec for the rotor clearance from rotor to front bearing plate? I guess I’m going to have to try and do them. Gonna take it apart and re inspect it. Maybe post some videos to YouTube. Thank you for your help!

So I removed the supercharger today and inspected it for any new damage or signs of wear and could not find any! It still rattled/knocks/grinds every now and then. I posted some videos to YouTube if anybody has time to check them out and give me your opinion of the cause of the noise I would be very appreciative! I did replace the rear bearings and rebuilt the snout but not the rotor pack bearings. I do have them though. I mean that’s all that’s left to replace besides gears right? I measured .008 on the clearances from both front rotors to front bearing plate. Is this bad rotor pack bearings? Or excessive drive gear lash? Thank you!

Some of that sound is what's called rotor clash. I have that too but I don't have that clacking and that other noise when you rotate your pulley by hand (mine is smooth) I don't recall the play in those gears, but when I rotated the screws everything seemed tight. Like rear end gears, I would think there has to be some play (backlash) but how much, don't know. Were you able to get that center bolt in the nose tight when you assembled it?

I think so too. The more information we share the better. Companies repairing superchargers are pretty tight lipped for their own reasons. We shouldn't have to send our chargers away for some repairs which aren't that complicated. Very costly and time consuming. By sharing we can avoid some pitfalls and save some $.

Hi Mike
Looks like it is definitely your gear back lash. Just took belt off my race car and there absolutely no back lash noticeable. Also checked those gears I pulled of rotors last week and the mesh is really tight. I would say your problem started when the supercharger run out of oil and has worn the teeth of the gears. Also it would be a good time to replace those front rotor bearings as they are probably not in a good condition either as they are also lubricated from the oil. Try Jon Bond maybe they can supply new gears. Cheers mate, it is nothing you have done. Also make sure you use the proper Anaerobic sealant when putting it back together Tony
