turbo rebuild posable

I was given an 83 or 84 Seca 650 turbo with wireing haress. Is a full long block with the manual and supliment manual. The turbo is in rough shape and needs to be rebuilt can this be done.The exhaust flange on the wastgate side is rotted off . The other question is can I mount the air filter on the turbo and plum it in to a custom air box or do Ineed to use the factory air box with the low boost {or no boost} reed valve witch was given to me with the motor. I have the complet setup less lights,frame and gas tank not bad for free so I don't mind puting some $ in to it. The turbo is a Mitsubishi TC03-06A.

 

Yes, there are a number of shops that can rebuild your turbo, at about $300. You might want to visit Injunheer's website at

for a list of shops. You can buy the kit and do it yourself if you feel so inclined (not a terribly complicated job) but you will need to have it balanced afterwards.

Just wonderin - what exactly is involved with balancing a turbo? Is it just checking the impeller shaft for runout?

 

Dunno. but I do know that it runs 120,000 RPMS plus at least My Garrets do.. NO place for DIY stupidity.
Truck repair shops are V familiar with Turbos and can do a cartridge/centre section replacement from $100 Not sure about some oddball teeny tiny turbo as found on an Ancient long discontinued Moto though. G'luck.

 

If you have time and are mechanically inclined, proceed. Mac has given you the skinny on turbos. Not overly complicated but a very precise balance is crucial to the long term survivablity of the turbine. Sounds like this bike needs lots of TLC. Are you up to it?

 

I up for the motor work as I'v biult a lot of motors befor but never a turbo. I have the motor but no bike with it. This turbo thing is new to me. The motor I can rebuild with help from the manuals that came with it and with the help of all of you.My 81 xj650 runs but needs it spring clean up real soon as I need to ride ASAP.

 

Apparently, a rebuild kit for a Mitsubishi TC-04 will also work for the TC-03. TC-04's were quite commonly used on Dodge Colt turbos (early ones). I wonder if it would be as easy as hitting up your local Mopar dealership?

Trivia: The TC-03 works around 175,000 rpm, and will go to 215,000rpm with no difficulty, so I think balancing is recommended.

Check out the http://www.turbomotorcycles.org website.

 

So in one SECOND that thing will spin about 3,600 times? My mind is boggled.

 

where would I get it balanced

 

Try these guys.

Give them a call - they may do it. They are in Georgetown.

 

Once again: A decent Highway truck overhaul shop They do turbos daily and are well equipped to to it properly Older Aircraft also use turbos could try that avenue but aero pricings can be highish, but no issues with the work. Also important to note: truck drivers/owners do not/cannot pay foolish 'boutique' prices

 

Danilo I never thought to go to a truck center thats a kickas% idea. I'm on my way out the door now. I'm new to the turbo thing done alot of xj650s and one xj750 but never a turbo car or bike.

 

Let us (me) know where you get it done and how the service and price was. I'm thinking I should get my turbo balanced because I'm pretty sure the PO had it apart.

 

Hold the phone! Actual TC-03 rebuld kits here:

$105. Not too bad.

Rebuilding it yourself might also not be out of the question. Seems that if you mark the parts before disassembly, you can retain the original balance of the parts (in theory at least).


Budget Rebuilding.

 

Thanks Mac do you know if the tco4 will fit or work with my tco3.I heard you can up grade to or with a tco4.

 

It's not a straight swap, since the housings are different. I believe Injuhneer put a TC-04 compressor impeller on his, with some benefits in low rpm boost (hit about 1500rpm lower iirc), but it took a fair bit of machining and welding. Best to stick with what you have and get is rebuilt if it needs it.

 

Re: turbo rebuild posable,absolutely

Hi Guys, first post. I have an '82 XJ650LJ SECA. I bought a turbo rebuild kit and found I have an extra part. I know what you are thinking, amateur. I am but I have a very good mechanical background. The rebuild is straight forward, lots of help on the web. The extra part is called a 'Thrust Ring'. In the videos I 've seen it's runs between the journal bearing and the oil plate. On my turbo (TC03-06A) the journal bearing is one piece and goes up to the oil plate. No room for the Thrust Ring. While I was rebuilding the turbo I would use a new part, set aside the old part. The Thrust Ring in question, no old part.
In short anyone rebuild a TC03-06A lately? And have a similar result?
Thanks.
