Not a lot of Nova work but plenty of “real” work done today. I had an important meeting in town and also managed to pick up two sheets of ½” plywood for the much needed stable floor for the Goody installation. It is the damndest thing though. Modern 21st Century ½” plywood is 15/32” thick.. Is everything going to hell? (I am an old lumberyard employee from back in 1960-61...)
On the Nova front I managed to put the TCI Breakaway torque converter on and have all in preparation for the tranny/motor mating tomorrow.. Tom’s advice about the two thunks was the ticket and the second one was difficult to find. I almost pushed the tranny off the stack of boards onto my foot.. But both of the thunks eventually showed up.
Ror41-1.jpg and ror41.2.jpg shows the male and female parts of the operation. (can’t help thinking about sex for some reason)
I measured the distance from the bellhousing mating surface of the block and the torque converter mounting pads and came up with 15/16” which gave me a ball park target to shoot for with the mounting. (sex again!) (see ror 41-3.jpg..)
Ror 41-4 shows the torque converter happy and snuggled in properly with a distance from the mounting ears to the bellhousing plane of 1 1/16”. This puts a 1/8” gap between the converter and the flexplate after the tranny is mated to the motor.. (more sex? Draganowski, you are a dirty old man..)
More to come..
(measuring is good)
Today was the docking maneuver day. (gonna try not to use any sex terms) I got Goody on the hoist and close to the tranny and then wrestled the guidepins and converter pilot into place manually by moving the transmission. (ror42-1.jpg is the starting point)
The converter could spin freely and was about 1/8” from the flexplate bolt pads after the six transmission mounting bolts were tightened. (ror42-2.jpg)
I put in the neat ARP 12 point converter bolts and torqued them to about 45 lb ft. The standard bolts are supposed to be torqued to 30 lb ft but I figured the ARP high zoot jobs could handle 45 easy.. GM says to tighten the bolt which goes into the radially slotted hole on the flexplate first or you get an Aren style vibration. Then the other two which have the slots in the tangental planes..
Ror 42-3.jpg shows Goody at working height all together (including the nasty black tin flywheel cover thingie) and getting close to installation.
Ror 42-4 shows Goody sneaking up on Rustpuppy at a stealthy level..
More to come..
(It won’t be long now..)
The opening picture is taken from under my “Shade Tree” which provides shade and the name of my auto shop.. You can see Goody eagerly waiting and Rustpuppy looking helpless.. (ror43-1.jpg)
A quick note on the Junkyard Dawg. When Dave was working on Patches I had him spend an hour cleaning up all of the surface rust dings and scrapes on the Dawg and primer and paint them. Since he was using blue, blue it was.. ((ror43-2.jpg)
Details need attending to prior to installing Goody so today was a detail day. I had the hole left when I pulled out the heater/airconditioner from Rustpuppy plugged with aluminum flashing and aluminum tape. Hardly an elegant solution. I wanted to keep access to the hole in the firewall as it makes torqueing the rear header bolt on that side much easier.
First thing was looking for the piece of aluminum (1/8” x 8” x10 ½” ) I had cut for the firewall door about 2 years ago. After wasting about 45 fruitless minutes I spent the next 25 minutes making a new one. (bet the old one shows up tomorrow.. bah!)
Then the hole in the middle and the piece of 2x2 for a toggle and a stainless bolt, washer, and nut and the door was done. I put a double layer of dense foam weatherstripping around the hole and the door was on in a jiffy.. (would have been a lot easier with a helper..) (ror43-3.jpg, ror43-4.jpg, ror43-5.jpg and ror43-6.jpg)
Now on to the ProMatic installation..
More to come..
It is Pro-matic all the way with this report. I wanted to get the initial messing about with the tranny done prior to installation.
Ror44-1.jpg shows the neat box the Pro-matic shifter came in. The first jarring note was the sticker on the plastic console thingie.. (ror44-2.jpg) I wonder what the out-of-work moldmakers and machinists in this country are doing these days..
Then I was amazed by the motly collection of bracketry and widgets in the kit. It seems Hurst is trying to be all things to all people.. (ror44-3.jpg) You know I resent having to pay for all that junk just to get what I need. (what I need is in ror44-4.jpg)
The next thing I noticed is that the steel plate the TH350 shift arm is made from is too damn thin. As a result the nut securing the arm bottoms on the shaft and the arm wobbles and flops too much for precision shifting. I added a ½” ID washer and a 3/8” washer to properly clamp the arm so it does not wobble. This is not a good sign. I thought that Hurst knew how to make these things.. Sigh.. The cable bracket needed the spacers to line up with the arm properly and the extra long bolts they provide are ¼” too short.. Details, details.. (ror44-5.jpg)
More to come..
(picky old engineer)
Today’s hour or so was spent on the second phase of the Pro-matic installation. First I figured where I wanted the thing to be. Then I felt around through the hole and encountered the spot welded in reinforcing channel right were the rear bolts go.. It is always something.. (ror45-1.jpg... note the tranny eye’s view of “The Hole”)
It says in the instructions that you_MUST_ mount the shifter on a flat surface and if you bend the mounting ears down it voids the warrantee and causes the shifter to foul up and jam. Since I am a tall dude I decided to use a custom made 5/8” thick aluminum spacer. (7075T6 aged 20 years and harder than mild steel) (note drilled and ready spacer ror45-2,jpg and 1 ½” hole for cable) That surface will stay flat..
Then the shifter in place and the 4 bolts wrestled in. It was pretty neat since “The Hole” allowed me to put the bolts in from inside Rustpuppy with a moderate amount of contortions and groveling.. (ror45-3.jpg)
The last picture (ror45-4.jpg) shows the shifter bolted in snug and ready to go..
Then I sat in the motorless Rustpuppy and played with the shifter. (like a little kid)
More to come..
(Goody will be home very soon..)
Serious and important work interfered with Nova work today but I did get just a little in. The most excellent Ben Meissner (Ourstanding Artist and Designer) took pity on my tale of woe relating to using *&^%#%^#*& truck motor mount brackets on Rustpuppy and sent me a pair off of his 74 parts Nova. They arrived today and I only had time to get them and the tranny dipstick tube cleaned up and painted.
Ror46-1.jpg and ror46-2.jpg show the small but important difference between them. Also the truck bracket is thicker metal.. I went crazy trying to make the wrong ones work and am glad to never have to face that again.. (at least until the Dawg goes back together..)
Ror46-3.jpg shows the painted brackets and tranny tube and ror46-4.jpg just the new (to me) brackets.
You will notice the tab which bolts to the bellhousing is missing on the tube. I just clamp it in place with a hose clamp.
I shortened the truck tube about 4 inches to fit it under Rustpuppy’s hood and hope I got the length of the dipstick right. From the bottom of the rolled bead which seats on the top of the transmission casting to the end of the dipstick when it is fully in is 2 7/16”. Does that sound about right?
More to come...
Painfully slow progress but some tiny progress today. After an urgent trip to town wasted most of my Nova time waiting in line and listening to Aerosmith at a stupid road construction mess..
While in town I picked up a replacement O-ring for the tranny dipstick tube. (after 23 years they lose some of their ringiness..) So all I had time for was getting the custom 2 piece tube in with it’s custom hose clamp and custom RTV at the pulled out spotweld holes..
Then I addressed the motor mount brackets. I checked first for the depth of the threaded holes in the block and found a couple that could not accept a 1” bolt with two washers and the bracket.. So I rounded up a half dozen ¾” bolts. I had problems in the past with the skinny pasty Goodwrench boys not tightening these bolts enough so I gave them about 38-40 lb ft..
And that is where she sits tonight. Just moments away from actual installation..
I just need one unbooked afternoon and evening..
(just four crummy little hours..)
A Nova work window about 2 ½ hours long opened up today. My first instinct was to go like crazy and just get Goody installed and worry about the details later. After a few minutes of feverish preparation reason intervened.
My training was to never let emotional bias interfere with technical decisions.. And here I was rushing off in an emotional frenzy.. After leaving the scene to think, I realized that now with Goody on the hoist at a comfortable working height is the best time to attend to as many of the little details of motor installation as I could. This would avoid the nasty crawling under the car with dirt in my eyes business as much as possible..
So that is where the 2 ½ hours went today. First thing was modifying and installing the detent cable bracket. Those stupid and no longer used ears had been bothering me for 5 years. I even put the recommended Tyrap on the detent cable where it crosses the dipstick tube to keep it constrained. (ror48-1.jpg and ror48-2.jpg)
Then it was press on to putting on the finishing touches and installing the starter heat shield I designed and made last summer. I used a 100% stainless 6 ½” hose clamp. The shield itself is made from two layers of aluminum flashing with 4 layers of extra heavy duty aluminum coated Kraft paper inside. It is trimmed with slit and RTV’ed on vacuum hose to protect the wiring. (ror48-3.jpg and ror48-4.jpg)
Then the balance of daylight was spent on rehabilitating the steel tranny cooler lines and the transmission modulator line. Steel wool and brush on black acrylic enamel for the cooler lines and the neat silver NAPA Commercial paint (as used on Goody and the tranny) for the modulator line..
More to come... for sure...
(the only time I know of that NASA forced a launch for political and emotional reasons was the Challenger.. Something we never would have done back in the days of Apollo... how times change, sigh...)
