Doorgunner's '68 Convertible Project
What the heck happened here. I can not view any of your pictures!!! Looks like Photobucket slammed your door shut. Time to release the pit bull again and get somebodies attention. Love reading your thread but man we need pictures. LOL
NORM





makes me want to ********!!!!
EDIT: I managed to find/transfer a few pics back to this thread.......

Here we go again....
Sorry, Men.....in May of 1968 I didn't like the green tinted paint on the rims---so I finally did something about it.....
I hit it with some satin black....it's a go....I'll sand/respray it & buff the scratches off the trim ring/cap tomorrow.....

This little monster gave me a fit.....the front brakes would not pump up.....the piston was seized.....

An hour later......buffing wheel/clearcoat/......

Final step....... .004 T.I.R on 46 year old un-touched rotors....they're done.......I'm happy






it took 2 hours to get all the bolts aloose/another 1&1/2 hours to break the crossmember/trailing arms aloose without pinning myself under the assembly......
I kept using longer pry bars---I finally ended up practically standing on the pry bat that extended out of the wheel well (that was good advice someone gave about leaving the mounting bolts slightly threaded into the frame!) Also.....my motorcycle jack caught the assembly perfectly so I could lower it a little to roll it out from under the body.
(Rats---I've got some scrubbing to do on the garage floor after the rear suspension is re-installed)................

Ohhh wait.........they're over here on a clean spot........

The rear calipers look about as cruddy as the fronts did...the rotors also appear to have never been "turned".......

It's all in fun.....lots of cleaning/sandblasting/ and a few coats of paint
ought to have it in daily driver condition.

The previous owner rebuilt the differential/emergency brakes (except the cable)/bearings and seals/u-joints/one trailing arm......
Maybe tomorrow I can start cleaning everything/repacking all the u-joints/bearings/replacing seals (from sitting up so long).







Sure......it's a MickeyMouse cabinet 36" wide by 24" high by 24" deep/portable blasting container to supply the sand/media....but the $$$ that I saved will get a pair of chrome rear bumpers (daily-driver grade)
To hold the weight of the differential, I'll need to make a support stand for the sandblasting cabinet that I built from spare sheetmetal......
Then do a few push-ups so I can load the differential into it...LOL!
OFF to the garage......Pics tonight....hopefully.
EDIT: GOOD NEWS!
The differential parts came back from the paint shop this afternoon.


(Actually, the parts never left my garage)

Maybe I can have everything reassemble by tomorrow night (excluding the trailing arm assemblies--they still need reworking/painting)
The Best of Corvette for Corvette Enthusiasts





But....better thick with a few runs than thin paint with rust in a year.
(Annnnd....I still spend a lot of time at my daughter's house since my great Son-in-law passed away at Thanksgiving.....so, progress is erratic)
EDIT: The only thing car-related was the DIY/ALEVE pouring of concrete for a parking "spot" for the "Vette Only"....I added 10' by 10' of concrete today to our driveway...with another 10' by 10' section of the form waiting for concrete to be poured into it next week.
It should make the new homeowners very happy to have an extra parking space (My darling wife decided that I needed a new home with a third partitioned bay in the garage for my "project")!

My dad bought a brand-new lawn mower from Sears & Roebuck...He was on the road for a week and I needed to know what was under the engine cover. Four hours later using my new 20-piece tool set, the engine was completely dis-assembled!
That was back in the day when spankings were LEGAL. (Did you know a competent spanking involves not being able to sit down for 1/2 hour?)
So....that next Monday I took the BOX of engine parts to shop-class at school---by that Friday I was mowing grass.
EDIT: Maybe this week I will get more work done on the car...............MAYBE!

When I removed the differential for cleaning and painting...this caught my rookie attention.....(not the missing bolts--I just removed them)

The cover has been removed/The splined yoke has been pushed into place/ and a mini-flashlight is shining on the problem area.....

According to forum members, it is no huge deal if someone previously forgot to install the retaining snap-ring. My concern is.....what if they installed the snap-ring backwards.....and it worked it's way off the shaft.
I couldn't find anything loose inside the housing by using my magnetic pick-up tool...so I emptied the oil out of the differential.......and there it was......A $1 retaing ring that could have gotten into the gears and destroyed (Murphy's Law) the Differential.....

The snap-ring on the other shaft is just starting to become deformed...so it will be replaced also....which will DOUBLE the cost of new parts--------now $2 !!!
(I will also spend about 30 minutes with a dremel touching/squaring up the shoulders that the snap-rings rubbed against)
Both snap rings were installed backwards.....an easy-to-do mistake
The gear backlash was well within tolerance and the oil was clean with no metal particles of any size....I'll pick up a new cover gasket this week when my seal kit arrives at the parts store.

Just trying to learn something here.





That's the same thing that I thought...but in helicopter maintenance training in the military...the instructor showed us that one face of a snap ring has a slightly rounded shoulder around the hole....and the opposite face has a sharp shoulder around the hole to "grab" the shoulder of the groove that it fits in as it is "forced" against the grooved shoulder.
What he said never seemed important to me, but I did as I was instructed (As they say "You can make mistakes on the ground, but you don't get the opportunity to correct mistakes in mid-air").

Thanks for the info

The housing gets 3 new seals (only 1 shown).....

The new snap rings are installed "sharp edges" against load-shoulder...

The new pinion seal has been installed and the nut is tightened down to the notched alignment marks on the yoke/shaft/nut plus a little "extra".......(I will need to clean the overspray from all close tolerance fits and faces before re-assembly)

I spun the gears to about 50 mph (LOL) using adapters on the drill (the camera "froze" the action/good thing that ratchet didn't get into the output yoke)---no leaks/no bearing noise/no gear noise/minimum backlash......

Since the highways are covered with ice (whatever happened to "sunny/75*F ??)....I might start reinstalling the differential assembly back into the car this afternoon.
Well.......while I was in the garage......this happened.............(bizarre weather for South Louisiana).....

The P.O. had a rebuilt driver's trailing arm assembly already installed, so after removing it and checking run-out and end-play I cleaned/repainted it (probably will not be dry until tomorrow since the humidity is high--as always.....and it's 28*F outside).....

I hope to install it tomorrow and clean up/repaint the passenger's trailing arm assembly.





I'll try to re-do the deleted pics (I should have a back-up CD)
