Thanks Nick! Yours looks good! Also, thanks for posting videos of the rebuilding job. It definitely makes tearing down the box easier.
I'm going to blast the whole case, one part at a time. Here are the left case half and the rear cover...

After:

I also got the last package of parts today including a NOS Renault clutch release fork from PJ Grady. Mine was looking ratty.

Tomorrow I'll put the 1-2 shift rod back together with the new spring and roll pins, etc.

Today, I was able to install the new spring and the reinforced roll pins on the 1-2 shift shaft.
New pins (normal size and smaller one inside), and the old ones on the blue tape...

Installed..

The outside pin needed to be level with the height of the spring otherwise it would interfere with the gear below it.
Prepped and painted the input tube..

Cleaned the soda off the rear cover...

Replaced the axle flange seal and transferred the gears to the blasted case half..

Tomorrow I'll blast the last part... the other case half and replace the axle seal, then I can reassemble the gearbox.

Looking good Dana. That blaster seems to work well, I'm thinking of buying one to use on my fascia.
Thanks Rich! Yeah, the blaster works pretty well for an all in one unit. You need to have good air supply and they recommend a dryer. I didn't have one, and the media got clogged up from time to time.
Well, after a looonng day yesterday, it's done, and being delivered back to DMC FL tomorrow. I'll post my last day's work very soon....

Great thread so far! I've got this one bookmarked for when I pull my transmission. I've been driving with a sheared 2nd gear roll pin since I got my car in '08. One of these days I'll actually fix it.
On Sunday, I started by adjusting the orientation of the inside roll pin so that the strongest portion takes the load...
image.jpg
Then I soda blasted the right case half...
image.jpg image.jpg
After I cleaned the case half up really well, I installed the new axle seals..
image.jpg
I used a seal puller on the old ones, and a bearing/seal driver set that I borrowed from AutoZone.
To be continued..

I cleaned the bearing races and case mating surfaces again with Acetone and assembled the gears in the right case with Loctite 609 in the 4 bearing races. Then I immediately checked for free movement of the gears...
image.jpg
Then it was time for Permatex Anaerobic gasket maker on the case mating surfaces...
image.jpg
Then, quickly a final wipe of the bearing races in the other case half and Loctite 609. Plus, I put a dab of synthetic grease on the case magnet and placed it ( to prevent it from falling out ). Because it was watery, I moved the 609 up the races with a Q-tip just before mating the halves.
image.jpg
Next, I ensured the reverse gear was all the way to the right and the shift selectors and gears were in neutral and gently mated the cases. I put 6 bolts in place and checked for gear movement and the reverse gear worked, as the gear tended to slide out of place. Then, I put all bolts in place and torqued from the inside out....
image.jpg
Next up was the 3 bolts on the the bearing retaining plate and the 5th gear assembly. I used zip ties to keep the assembly in place in the meantime...
image.jpg
Next was LIBERALLY applying red loctite on the shaft and nut threads, torquing to 112.5 ft/lbs, and peening the flange in the shaft indent...
image.jpg
That was the 2nd flaw addressed.

I cleaned the mating surfaces with Acetone and used Indian Head gasket shellac on both sides of the 2 paper gaskets for the covers. Also in this pic I put the 2 new drive axle flanges on (lubed the rubber seal and the metal contact first)...
image.jpg
Inserted the input tube and seal, placed the clutch housing, and torqued it...
image.jpg
Installed the rubber cup/seal, after gradually stretching the hole to fit over the pivot ball..
image.jpg image.jpg
Mixed up a 50/50 "Grady goop" discussed earlier in the thread and applied it liberally to the pivot ball, socket, and the metal fork spring (to try and prevent corrosion). The fork spring goes in the wider slot in the ball between the seal and the cover..
image.jpg image.jpg
Finally, I installed the clutch fork bellows, the slave, the throw out bearing, the 5th gear dent ball and plug, painted the speedometer plug, and refreshed the green factory paint marks....

That was Sunday. This morning, I loaded it up and delivered to DMC FL..
image.jpg
Car and gearbox reunited..
image.jpg
..and to think a couple years ago I was hesitant to tackle the fuel accumulator.
Many thanks for everyone's help and advice that made this rebuild happen in 9 days.
