Shop charged $75 to coat the rear end. 

 

I built my own vapor blaster (I like that name) system.  It's pretty simple, my cabinet is a giant piece of junk, but other then that is awesome, it's not a fast process, but makes things look amazing.

I got some zinc parts back. Sadly the aluminum is more pitted then I would like. But nobody will know but me. 

Also I got my osgiken LSD. Sadly the K R180 I got was from a 87-88 200sx. So it has the beefier 11mm bolts instead of the truck 10mm which the osgiken is setup for. I have the silly expensive LSD at a machine shop having the holes inlarged now. Fingers crossed they don’t mess it up. He is a very good machinist. 

All better. Holes drilled to 11mm

More parts off to zinc. Also got the longer 74 drive shaft back from powder. 

 

What a pain to prep these parts. Last time I powder coated some of the half shaft parts. Which was a mistake. So i will zinc them and the drive shaft parts. I also decided to zinc the rear engine dust plate. 

Got the trans parts back from zinc and got most of the trans rebuilt this weekend.  

 

This is my first time doing this.  I used the FSM, friends and this youtube video.  Super helpful.  Also a shop press jumped for sale locally, I picked it up for 80$.    

 

Youtube video. Below.  Here is mine spinning. I had to take mine apart a few times.  So I am a little worried I put some wear on the bearings.  I got a brass hammer which seams to help a lot.  

 

 

 

 

Looks good,  was it any harder to press the new bearings into the center flange with the added thickness of the zinc coating?

No that was a non issue.  I just forgot a C clip one time, then forgot a shim/ washer:)

Bolts torqued and bearings pressed. I also got the pinion seated. I had to buy a smaller Torque wrench for the bearing pre load. Seating the bearings for the pinion was a giant pain but I got it. 

 

I love owning s press. 

I ended up buying a small torque wrench, which helped dial in the bearing pre load on the R180.  Worked great.  

Well I don’t know if the effort was worth it. But the 5 speed trans is rebuilt. Shifts great. Looks killer! I would guess next time I will just buy one rebuilt.

Very, very nice!!!! This Z will be a blast to drive. What ratio did you get in the LSD?

4.11 it’s going to be a rocket ship
