... It's the M/C & S/C FROM THE GRUMAN VaN . it work 15 years ag with the Gruman why will it not work today with my lighter body.

Perhaps the pedal travels further then the slave can. Maybe have some one watch the slave and see if it stops traveling before you reach full movement on the pedal.

Bojon may be on to something. Its hard to tell what clutch was being used on the Grumman van. Perhaps the clutch travel was further or deeper allowing the clutch pedal to push the throw out bearing further.

However now when u are pushing the clutch in ,the throwout bearing is stopping when the clutch fingers are maxed causing to much pressure and trashing your o rings.

The only thing that is different in your Bronco now from the Grumman van is the clutch and tranny. And if the master and slave worked then , no reason it wouldn't work now.

My bet is what Bojon suggested.

Let us know!! I am curious now.

Well today it was crazy warm and just so happens that the jeep was all back together and ready to drive.

The clutch bracket and linkages worked so great. The pedal was firm and solid, no pops or funny feelings.

The crankshaft sleeve and oil seal as well as the third time rebuilding the vacuum pump resulted in zero oil leaks. I drove the jeep Prolly 100 miles today around town and running some errands.

I stopped in a local performance diesel shop and bought a rebuild kit for a Holset HX 35 wastegated turbo that I scored for crazy cheap. I also picked up another drain tube for the currently installed Holset H1C . I am getting a kink in my current drain tube causing a small amount of blowby

The exhaust so crazy loud on the freeway. Maybe looking into a muffler insert to quite it down a bit or go put the hard top on and see how that works..

I will post some pics of the turbo later tonight

As promised here are the pictures of the turbo rebuild. Truly wasn't going to start this project yet but I couldn't resist the urge to learn how these things come apart and go back together.

These next couple of pictures show the turbo as I bought it in its rusty glory. The turbo has a bit of shaft play and might of had some compressor wheel rub on the compressor housing. I couldn't make the wheel touch by hand but the wheel shows signs of contact.



Attachment 553858



Attachment 553859



Attachment 553860



Attachment 553862

Now starts the fun part. There is a snap ring which is behind the compressor housing and when removed allows the housing to pull off


Attachment 553867

The below picture of a close up of the comp wheel and the scratches on the edges of the blades. I am going to take it to the professionals and see what they say.

Attachment 553869

Next up was removing the exhaust housing . Now in theory this is simple however in practice this is a disaster . There will be four bolts holding a ring which hold the housing to the center rotating housing . These bolts can break easily and did on my h1c . However this time I got lucky and they all came out.

Now it's time to grab the bfh and don't be afraid of breaking anything . I struck the housing in the circular pattern and it broke free pretty easy. The picture shows exactly what u need. PB blaster and a hammer.

Attachment 553872

To remove the comp wheel I held the exhaust nut with a large pair of locking pliers and my vice while I used a wrench on the comp wheel nut. Caution the comp wheel nut is reversed threads.

forumrunner_20130129_224456.jpg

After removing the nut gently tap the shaft which will push it through the center housing . Use caution so the shaft and exhaust wheel doesn't pop out and fall.

That is as far as I made it tonight. But I am sure I will be working on this very soon.

Got more work on the turbo rebuild done tonight. I have everything ready to be blasted tomorrow.



forumrunner_20130201_003446.jpg

After removing the snap ring the center section pulls out with the use of channel locks and pb blaster. There is a rubber o ring which seals the center section and the pb blaster will help it come out.



forumrunner_20130201_003837.jpg

Inside the center section there is another collar which must be removed and a c clip ring replaced and then re installed.



forumrunner_20130201_004001.jpg

Next the brass piece comes out and will be replaced.

After the brass piece is removed there is one more thirst washer which needs to be removed and replaced



forumrunner_20130201_004220.jpg


After that there are snap rings which hold the brass bushing in place. Once removed the bushing come out with your pinky finger jammed into it.

Make sure the bushing races are clean and free from scratches . My compressor side is smooth although the exhaust side has one scratch which I am going to have the shop look at. Its really small but none the less . I am crossing my fingers that the center housing is okay. A new center housing is like 600 bucks. Not what I want

I also posted a video of me playing in the snow with Oscar. In my first video just click on my username and it will pull up.

Well good news from the diesel shop. The center housing was fine with no scratches . The machine shop which is in house honed out the bushing races.

I do have to buy a new compressor wheel because my old one did have some damage.
