Thx tim. It would be silly to spend weekends changing all the damaged or rusty metal and not do the last bits!
That's one of these activities where you think about those having space and a rotisserie and grow some jealous feelings!!  Surely doing the underside on the ground isn't the most fun part of a restoration. Oh well, it's done now. ;)

Yes, Fabrice, I well understand that. Don't ask why... But it's me too crawling under the car, with fallin' 50 year old dirt in your eyes and ears, grabbing some old metal and saying to yourself: keep on going, keep on going, we will be finally there :rofl:

Oh yes, I know that feeling :beer:

But now, it's done - congratz :wrench:

Mustang time again!

AOD_prepandspray.thumb.jpg.f8f7da66cf86a70b88169a69ed2d0a22.jpg

Because my AOD parts should arrive soon and haven't been able to paint the casing yet due to the really bad and cold weather that we have since forever over here. 
Which would become a problem as it needs to be done first.
So as the weather app gave me 2 or may be 3 hours that should be dry, I've jumped on the occasion and after a good clean in and out. I've mask the many openings of the trans and applied first primer followed by a grey metallic, finished with a semi gloss coat.

 

AOD_painted.thumb.jpg.6f523d5dc4b2d478febbad99fe94f259.jpg

The Mustangs gods were with me and asked the sun to come help for a few. 
That unexpected help plus the heat gun got the coat dry enough for me to place the trans back inside where it could continue to get hard at its own pace...

Yesterday, everything was hard and I was happy with it even if it won't earn a beauty price due to the poor quality of the cast. It looks much better now and with the new pan that it will receive, it should be bling bling enough for the 73! :)
I tried to save the original one, but there were too many rust pits almost gone tru the entire thickness of the metal. As I wanted to add an oil plug/bung, this affordable after market pan was just a better move.

Not able to spray anything else as rain had meanwhile returned, not able to do any dusty things either, So spent rest of afternoon looking at some of the parts that I've received in past weeks more in details, tested their fit and selected a series of these that will need to be sprayed or plated. 
Looks like many new parts are now days stamped as "is ok to rust"... So added some on my toBePainted waiting pile like these top arm parts...

Sunday was for the 71. The next on the todo was to apply epoxy. Not a biggy, but in my garage this means loads needed be packed, protected and protections hanged to somehow by magic turn my little cave into a spray booth.
After a good clean, sanding of the zinc primer that was sprayed on during past months, I've slowly but surely terraformed my garage into a Martian landscape. After many refills and one kilo epoxy gone thru the nozzle, I ended up with the bay covered.

Started first under the firewall, then lower firewall and aprons. Then did the frame underneath, as you need to be able to jump in again to do the cross members and the lower sides of the frame...
Of course, doing that I've touch the tower with my fat a$$!! grrrrr  :D

 

epoxy_2.thumb.jpg.06852e8b362de479e37548f05967dec1.jpg

After all was sprayed, I could inspect and while most was ok, some hard to reach places (deep in cowl vent and very high in cross member where the gun would not fit) have not received enough, so I will probably be busy fixing that with a brush next weekend. For the rest, aside a few details that I'll correct it all turned pretty ok.
I should not have much to do before thinking about spraying the final coats.

All with all, another productive weekend with the impression to have done something has passed!

To be continued...

Thx Tim. Yeah, really tired of this crappy weather. The last time I was able to spray was late august last year! We had since then a couple of warm enough weekends, but none dry. The few good days were of course during the week grrrr :D

As a child of the outgoing 80ies he will keep the yellow along with yellow spark plug wires. Match is match - what else?

It's a rare mach 1 "Bob The Builder" tribute!! :D

Of course it will receive satin black! Depending on brands, epoxy comes often in these colours as it is used in industrial applications. This brand is used in nautical fields. I must say it's handy as you really see how all is being covered. A white or grey would not have let me see that easy that some places like deep in cowl could have used more. If your recall my hood, fenders etc... Same was applied before primer and coats of different colours were applied.

Long weekend yeah!
Rain, rain rain, who cares!? I need be inside as I'm still waiting for my 73's parts...

epoxy_prep.thumb.jpg.effac437d44f23ee4026e6e16f7341fd.jpg

So I went back to my BobTheBuilder tribute, and started by correcting small metal and welding flaws with a tad of bondo, and applied panel kit...

Later in the afternoon, the epoxy yellow had left place to the grey colour of a fine primer.
Happy days! :D

 

wetsanding.thumb.jpg.9e81734625fd4f72adbb62efe38852f1.jpg

Sunday began with a tedious wet sanding session. I'm not after body like surface, but if I wanted to get rid of few flaws, it was the time to do so!

 

happy1.thumb.jpg.5e72a5485af58faa23f6751d1bd27a3c.jpg

After a good clean, I started to spray the final 2k semi gloss and I was having a big smile under my mask as all started to look fine...

 

happy2.thumb.jpg.74b3bec973b9b2968e497feb190e6de0.jpg

Started with the cowl, firewall, to then did the sides and the underside of the frame. and my smile was growing...

That was till  I went back in.
To finish the front part of the towers, the apron, and after a final climbing, the radiator support...

not_happy.thumb.jpg.ad32e26522430d83917bea7e71dd00e3.jpg

As this point, me totally unaware that the paint started to harden in the gun, became sirup and in matter of a few sprays, the previously fine mist lost its finesse. 
The gun became bloated and once aware of the issue (too late), despite my attempts to thin up the mixture, the damage had been done.

At first sight right after spraying, the paint still wet, all was looking pretty ok despite the issue and thought that may be, once it would dry and that some surface tension would occur. it would have been ok with me.. 

You can see on the first image above of entire bay that all was looking okish.. 


But this Monday, evaluating the result, my smile had definitely left the building! :(
Sure it's not a disaster, not that terrible either and many would be happy with that, but after so many hours, I just can't accept this result as it doesn't reflect at all the extra mile put into it. And last but not least, I know it will bug me each and every time I will open the hood!

Sooooo, I'll be water sanding the aprons, radiator and anything not smooth again as ment to be and respray this again asap. I guess I payed the price for using a paint I never used before, unaware it hardenned faster than epoxy or any other paint I often use.
Not a biggy and part of the game, but always desapointing  when that occurs. You have to have pain to be beautiful they say... yeah yeah I know! :D

Other then small parts with a rattle can... I learned the hard way years ago. I wussed out and paid to have my car and engine bay painted. A man has got to know his limitations...  sometimes we are destined to learn through our mistakes. Good luck with the re-do.

True, tho here it's a chemical thing. Been in touch with the company delivering me my paint and they confirmed this particular paint should stay sprayable at 20c/68f for at least 2 hours when in the cup with the provided thinner. Even taken wide in time, it took me less than 1/2 hour to spray all from the moment the paint was mixed. They offer to send me paint again, free of charge, which was unexpected.

Looked again yesterday now that it's really dry and it's not that much work. the "ugly" part is not that spread. I need only to fine sand light the two front aprons to remove the mist, the top of radiator mount and in front where the right headlight support is. The other good news is that this paint can be sprayed over without reaction, where otherwise I thought I'd first need to spray a thin primer layer. So will mask from towers and should be done within an hour tops.
I'll nail that biatch paint! ;)

Always great to see your updates. Killing me not to be painting my car now. Should actually be putting together. My first Dr. visit is June 9 and see when they can do surgery.
I have done some de rusting in my molasses and things that do not upset my neck and back.
You will be bolting on parts soon.
Which NPD do you get your parts from? I am in North Carolina and I use the Charlotte one. Covid has taken so many here. Some do not have issues but others do. My neighbor barely made it 82 days in hospital in coma with feeding tube in her side for months. She is home and getting around good. She walked over to look at my car when loading into car trailer.

When a man is in the woods and talks and no women are there is he still wrong??:P

The main infection was in their Florida warehouse, with over 20 positive cases. 3 in critical condition in hospital, and one who passed away. They had a replacement team but it also contracted the virus. It's only around mid May that they were able to resume international shipping with reduced personnel, a pile of orders to process ofc, it took them over a month to have mine processed, and last week they shipped it with extra fast UPS, package was at my door in 4 days!

This virus is terrible. We are officially approaching the 4 millions deaths, and that's the official numbers. When you see the latest news in India alone, you know the numbers are way off...

In the US too many have the opinion "you cannot tell me or make me wear a mask". I want to go up and slap those without a mask in public. What idiots. I was growing up when polio hit. We took our shots and eventually went to oral doses. Americans today are IDIOTS.
Yes it has been tough last year and half but people not doing what is right just makes it worse. I have friends in China and if people did not stay home they welded their apartment doors shut. Yes welded they are all steel I lived there. Friends there tell me they are doing way better than the U.S.. Maybe the good side of this we eliminate the IDIOTS. The guys at NPD have always been great to deal with but sad to hear of their issues. I actually let deliveries set for several days before I even open. I would never make it if I got Covid.

Waited a month to get my parts from NPD, waited 4 for my AOD parts and last week along with other small orders like oil, paint etc... all came within 2 days.
So as my 73 is being still for more than a month on my driveway and we had the first sunny, non-cold-dry weekend of the year. I wanted fix that rear end...

For the record, +- 15 years ago, when the 73 was in garage in parts, not having the knowledge and the confidence I have these days when it comes to our car, I decided to let a pro rebuild my 9 inch traction lock with fresh 3:50 teeth.. I never drove it till end of last year when car was finally road worthy and put 4 or 5 hundred miles on it since then.

Because it's been revised by a professional company doing only rear ends and trans, having such a massive leak on my brakes must be a sign that something went badly wrong inside... May be some corrosion after so many years still had occur? So to be prepared I had ordered by NPD: bearings, sealing plates. Not knowing how many splines, ordered 2 sets of seals of 2 sizes as there are on our babies 2 kinds. both 2.25 outer one for 28, the other for 31 splines axles where the diameter is a tad wider for the 31 and of course new shoes as they have been soaked for weeks into gear oil, no brake cleaner would have restored that...

past_weekend.thumb.jpg.4cb29d2ddc1d4b32bacfe02abff29b1c.jpg

After using 2 cowboys tricks that worked extremely well and fast which otherwise would have required expensive tools to remove both the axle and the seal deep inside.

I've ended up looking at a perfect axle.. The bearing that were supposed to be replaced were new as expected, zero play, marks on the casing showed the perfect sitting. The axle had no marks of damage/wear. The vent tube of the axle was free, oil level within range with the additive and the seal was looking alright so overpressure was out of order. Inspected the seal before removal into the casing and closer after it was removed. Lip/spring was as new.

WHY IS IT LEAKING THEN?????

Well, it took the hobbyist that I am a good 1/2 hour to inspect and check everything to find out that the professional had installed the wrong seal type. They had installed the 31 splines type which ofc has a bigger inner radius... raaaaaaaaa!!! No wonder it started to leak!!
As I had also a set for 31 splines axles, compared them and confirmed.

So for the entire weekend, I've been swearing under the surprisingly warm sun, put back the axle with the proper seal, put new shoes on (oh boy do I hate servicing drums brakes!!! Always been a pain for me). And knowing what I knew, I had to do the other side as well because chances were high they would have done the same on the other side... 
Once it was out: bingo! Same mistake, at least this company was consistant! So serviced that faulty seal too and replaced the practically new shoes that were on with new ones.
While underneath, also reinstalled my good old traction bars that I've restored. I wasn't planning to reinstall them, but as I could feel they weren't there anymore in the corners, I've placed them back.
While busy on the brakes, I've replaced the proportioning valve and bled the entire system with new fluid. I've finished the weekend at 22:00 after replacing the engine oil. Too late to start the loud v8 without waking up the young kids next door. I'll check the car and take it for a spin somewhere this week.

Once more, this experience shows that trusting a professional on this side of the pond isn't perse a good idea, no matter the reputation they have. Our cars are simply too old, too exotic for most shops over here and it's easy for them to make mistakes just as we make them!

Oh well, my muscles are crying from this driveway crawling weekend, but it's corrected now!

Next weekend: AOD joys!

Now that my rear end is fixed and not expecting it to leak again for a long while
I've returned to the the AOD rebuild joys..

AOD_joys.thumb.jpg.ab9a4dab60447eafc08613dee872da32.jpg

Aside the casing that is now as new, only the pump was in need of love to be as new both on the inside as the outside. All hardware is now done too..
 

its_about_cleaning.thumb.jpg.ae7b41e5fe0c07fd9aea0915090e01c2.jpg

I won't go into the details of the AOD rebuild, but in this case, because it was in very good shape inside, it's all about cleaning, removing rings and rings and rings and when you're done, it's about put all these rings back and cover all in trans oil or Mr goo (which i highly recommend) or both ! :D
And of course watch the great guiding videos from Ken at badshoe.com
The AOD is much more complicted than a C6, but if you take your time it's no rocket science, especially when Ken got your back.

I've ended the weekend with all back in, all new but I keep the complex valve body for next weekend.
I need prep the space first for it as it's full of dozens of tiny valves and springs....

 

lipsealsizers.thumb.jpg.7dfd8e7eea3e85293560fa8d3e85c4e9.jpg

One detail tho...
If you have done an automatic trans like a c4, c6, fmx, you know you need to change the pistons seals of all the clutches.
On these transmissions, the seals are square cuts, and it's all about lubing them, engage the piston and push. Even on some where you have special ring seal tools
a bit of patience and a good push can get you there. In a C6 the chamfer in the drums is making the install a breeze and I do not see why you'd need to use any tool. 

However, the AOD, AODE, 4r70W and more newer trans are using lip seals type for the pistons. Even worse, the drums, at least the cast version for these are not having a chamfer to help guide the lip into the bore. because the cast is quite sharp too, trying not only will fail, but you will damage/cut the seal for sure.
So only way to get them in, is to use seal pushers. basically a cup in which you push the piston with seal inside and because it's just a bit smaller in diameter than the bore, the seal gets compressed against the piston and you have to push real hard to get the piston in, and sometimes even harder times to remove the tool as in some case, it's beyond max space and the seal can even get damaged when you remove it.
A good set of seal installer, not really cheap for a one time use, is even a must on newer trans as the tolerances are very tight...

That's when Ken comes to the rescue. With the rebuild kit comes a set of very simple, yet very smart 3d printed "sizers" for just a few extra buxx. They do like the regular seal installers that have been around forever, work same way. You push the piston and seal into a wide cup, that reduces its diamater on it's base and once the piston is in. 
That's where the similarities ends: It's time to freeze them! After at least 2 hours, you can push the piston out of this cup and the lip seal keeps its compressed position.
With totally zero need to push, you then simply drop them inside. After a couple of minutes, they are souple again, and the lip seals perfectly. No efforts to install
and what makes them totally superior to the classic way: no damage to the seal as they never get compressed in own thickness. Thumbs up to Ken for these!

Hope to finish the trans next weekend. After that I'll resume activities on the 71, as Summit has some delay for my converter, yoke and other swap related items.
