3.4L TRD Supercharger rebuild

Still kinda confused. Are the front bearings in the snout or the housing? I have a need snout assembly so wondering if there are bearings that I need to replace in the front?

 

Thanks for the heads up, yeah send it whenever you can. Appreciated

 

The front bearings are in the snout, which are the part numbers I gave above. What gen do you have 1st (tan/gray) or 4th (black)? The 1st gens don't have a factory nose cone replacement anymore so you have to replace them yourself or have someone do it. The black SC's have a factory replacement that you can get through Toyota still and takes about 1-1.5 hour total to replace (less if you don't remove the SC off the truck).

A supercharger consists of 6 bearings total. 2 in the snout or nose cone, 2 between the rotors and rotor plate (6203 Nachi C3 Open) and two rear needle bearings which the ends of the rotors go into. Most people are able to replace the nose cone bearings, seal and phelonic drive adapter and be good for a long time, but some need the rear needle bearings and rotor bearings replaced. Just depends on the SC and condition of the bearings.

I was running the static (old style) tensioner plate for 6+ months and no issues at all. It's a pain to tighten the belt correctly, but never had any slipping. I have the dynamic now and it is worry free and nice not to mess with the alternator adjustments anymore though. If you don't feel like spending the money now, just go with the static and upgrade when you have the extra cash. It won't hurt the SC to use the old style at all.

 

Found a thread a couple of years ago that had a tensioner for $48. Had to buy a $10 pulley to change out. Has worked great so far. Try searching, no clue where I had found it.

 

I have the 4th gen. Already bought and replaced the nose cone last year. Was just wondering if I really needed to replace other bearings or if I could slide for a while. Thanks!

 

Thanks for the info too, although I'm like a good portion of people who like to get it all done "right" the first time. I can wait, if it means putting in another $250 into it worry free then I don't mind.

The above forum is were I am pretty sure I found it. Amazon has just the tensioner for $36 right now!

Double check just to make sure.

 

Watch out for Shellyshel90 or something like that. He said he had a tensioner bracket available, had me pay, then gave me the run around for the next 5 weeks before saying he didn't have any or any means to get more.

If you're not hearing anything abnormal then you should be good.

Hmm, haven't seen the two pulley one, but my one pulley worked great.

Yeah if you can swing it then go for it. I never cared to dump $250 into something that worked already, but the dynamic tensioner is better in the long run.

 

The bracket is very simple. Mine is currently off. I could get some measurements if you like so you could make it yourself or take it to a fabricator. If you get someone else to do it then it may not be cheaper than just buying the whole kit from Toyota.

 

Yeah I was talking to that guy about that one but when he said he was keeping the tensioner I lost interest. Not a bad price at all though. I got a 4th gen sc with the dynamic tensioner for $725 recently and so far it doesn't need a rebuild yet.

 

Is there another source for the rear rotor bearings? How do you know these bearings need to be replaced?

 

I think I need to replace that coupler in mine after only 30K miles starting to make noise at idle in gear.

 

When I took mine apart I pulled out the rotors carefully and the rear bearing grease was still nice thick and blue the needles looked smooth and un-burnt So i left them be.

I bought parts from this place.

Dose anyone who has rebuilt there nose drive,have the part number for the nose cone seal. I had replaced the nose drive and coupler 2 years ago and now it's leaking. Only because I took it off do to the fact I didn't have the 7th injector kit. I'm assuming it's a skf double lip seal . Any help is greatly appreciated.

 

I would get one from here. Probably best price and ease. http://www.rollingperformance.com/scoil.htm

 

Thanks for the quick response SCrunner12. I've just check out the link you posted. The prices on their website are very reasonable. I'll have to get me a seal this week, so I can get the charger ready to go back on. Then I have to is get the urd kit.

 

No worries, I've looked for cheaper solutions but rolling performance is your best bet.

 

Yeah I have also tried to find cheaper solution but with no luck. The only I haven't found on this topic of supercharger rebuild is that if possible can just replace the front seal without disassembling the nose cone. Cause the nose drive I replaced only has about 4000 miles on it .

 

Definitely is possible. Remove the nose cone from the sc. Remove the pulley, then snap ring and remove the seal. Depending on the type of seal you can just cut or punch a hole and remove. Then just put the new one on.

 

Thanks SCrunner12, looks like I'm going to have some fun next week getting the supercharger ready. If I can remember I'll post a short write up of the repair with pictures.
