Making the jump N/A to TD

[burn_your_money]

40-50 sounds like money well spent when you consider how fast that turbine is spinning.

I haven't seen the head yet but it should be uber clean, it's freshly rebuilt

10 minutes of heat, TAP TAP TAP...Nothing
Let it cool for about 5 min.  More PB,  lots of smoke, more PB, TAP TAP....
nothing.

Will try the same thing tommorrow, and everyday untill it gives up and comes apart.

[subsonic]

The metal clamp ring is still attached. I mean it is loose and all, just held in place by those two bolts.  I can't get a clear shot at the joint.  Until the joint comes apart, or the last two bolts come out and I can lift the ring I can't get at it.  It's a solid circle all the way around the turbine.   How the hell do these turbo shops do a 1 week turn on these things? :?   All I can think to do is just keep hitting it with the heat and PB and cranking those bolts out some more until the joint starts to come loose.
Either that or I need to get a rubber mallet to really wonk it with.
I will heat it again tommorow and try some bigger taps.

 Do the same heating prior to tapping and be sure that you take necessary precautions so that if it suddenly comes apart the turbine housing won't fall and get damaged or damage you.

Instinct says grab it befor it fall's.  Hot potato!!!  :lol:  I am going to go looking for my nomex gloves.

Andrew,
Does your turbo from the 82 have the solid metal ring clamp all the way around the turbine or does it have smaller seperate clamps?
I am thinking of cutting off the ring clamp.  

I just looked at the turbo again, then my rebuild kit.  I have six clamps in the kit.  My turbo only has three clamps on the compressor and this single ring clamp on the turbine.  I am guessing that the 3 individual clamps are an update over the solid ring.  I am going to call the kit maker and see if they can confirm this.  If this the case, I am cutting that thing off directly so I can get access to the joint seam.

[subsonic]

Victory!!!

The deed is done.  I have the turbine and compressor off.  I had to stop because I did not have the 16 point 3/8 socket.  Off to the store.  Center section is stored in a box lined with foam so no fins get bent.

I called the kit supplier to ask about the metal clamp ring on the turbine.  They said to cut it off and use the replacement clamps.  I went out, bought a Dremel tool and cut that thing off directly. Once it was off I had clear access to the joint.  3-4 min of heat, tap tap all the way around.  Off it came.
  I deserve a big fat cocktail and some quality time with my wife!!!

I will post Pictures later tonight of the tear down progession

Bump. It's apart.

Dissasembly photo's added to page 5.

:lol: I've done the same thing with one of my 12 points :lol:

I tried the 12 point on this one but it slipped-twice.  I figured I did not want to strip it so I am going to try the correct one.

What do you make of the scoring on the inside of the turbine housing?  It's not from the blades. They are in fine shape except for a ton of soot and crap on them.  Seen anything like that before?

Great post!  I'm enjoying it.  Where have you been getting yur rebuild components, i.e. pistons, bearings, etc?

Hey Guys, I'm considering doing a conversion on my 1.6na but was wondering has anyone tried using a water/meth kit to keep EGT's down on this engine? Seems like that would be an easy way to keep EGT's at stock levels when combined with an intercooler. Maybe this would help combat the fact these engines don't have the oil squiters or the better head.

the oil squirters help cool the pistons themselves.  the n/a will never be able to cool the pistons.

TD pistons can run with quite a bit of smoke/heat, whereas the n/a pistons will start to burn up a few hundred degrees earlier.

regardless of that though, any means of decreasing the intake temperature will really help keep smoke down and increase the longetivity of the motor.

i'd say go for water/meth injection.   the only downside is having to refill the bottle.

Great post!  I'm enjoying it.  Where have you been getting yur rebuild components, i.e. pistons, bearings, etc?  

I did a bunch of research here for part suppliers, asking members etc.
I also have a friend who works in an auto machine shop for a large auto parts store.  He has been a godsend.  He has helped my get a bunch of my parts at his cost.( cost plus 10%)  That has saved me hundreds and hundreds of dollars.  

On that note,
I just ordered some more parts.

Intermediate shaft bearings, o-ring etc..  The ones in the block looked great, but if the block is out and stripped I would be a moron not to swap them out.  

Both motor mounts and the transmission mount.  Same logic as above.
Has anyone heard of a upgrade to one of the motor mounts?  I thought I saw a article about an improved mount?  Not a poly mount, but a redesigned unit  :?:

Connecting rod bearings.

Will have more photo's of the turbo rebuild posted in a week or so. Just had the compressor glass bead blasted.  Nice and clean.
 Had to head to New Orleans for a wedding and some drinking / mental health break a week or so ago.  Now hunting season is just around the corner and I still need to sight in three rifles and my muzzle loader.  AHHHH!!!!  
I need more hours in the day and a bigger paycheck!!

I need to get going on this ASAP.

[rabfan]

I ordered the same kit a week ago as well as motor mounts and a pump rebuild kit. Thanks for posting your progress. I will refer to it when I rebuild my stuff.

[subsonic]

I am rolling forward again.

After dicking around for way more time than I wanted to looking for a used 1.9 head, I decided to just say the hell with it.  When I figured out the cost of fixing my 1.9 head, and looked at the cost of buying a used one and then having it rebuilt it just was not worth it.

I bought a brand new, complete, Kolbenschmidt 1.9 AAZ head.
I sure hope this 1.6/1.9 setup works like it should.  I have a lot more invested in it now then I had originaly planned. :shock:

Got some more work done on the turbo rebuild tonight.

Right between getting the kids to bed and putting the lights on the tree, I managed to pour a Jameson and ginger or three and get the center section apart.  Working at the kitchen table under the watchful eye of my beautiful wife,( who was kind enough not to roll her eyes :roll:  at my in home endeavor  ),   I found two flat spots on the balance nut and spun the top bolt right off.  Directions said to gently tap out the center section with a rubber mallet.  I did not have one, and because I am a horrible procrastinator, my tool boxes are not accessable.  Why?  Because two days ago, with snow coming down :shock: , It was a mad dash to get the lawn and driveway picked up.  My garage has crap packed in it 5 feet tall, and front to back.  Where the hell does all this stuff come from?

I did not want to wang the threads up hitting it with the 3 foot breaker bar I was using, so I folded a hand towel in half, put it over the threaded rod and gave it a gentle breaker bar tap.  
Damn threads poked right through the hand towel!
I made the call to sacrifice one of my wifes soft plastic teaspoon measuring sets.  I put one of them over the threaded rod, and then the towel on top of that. Two solid wacks and the shaft was free.

A free shaft is a good thing!  Ha hahahaha :lol:

Took the 4 bolts off the backing plate, gave it a tap and it fell right off.  The whole thing is apart now.  There is enough coke in this bad boy to make Tony Montana (scar face ) lose his mind.

Had to get it all picked up and put away asap, lights to be put on the tree don't ya know.  
I will add some photo's when I can.  My wife would have tossed my christmas presents out the window if she saw me picking up her expensive camera with my hands all black and covered with shee-iit.

I hope to get this post all put together as a how to when it's all done.  I will get with a mod when it is time.
