Would love a medium tee shirt.
Got to support the Barn!!

It has been fun and educational. (IMG:style_emoticons/default/biggrin.gif) Cool deal on the alternator. Axles came out nice, big CV’s

Phasing CV joints. And boy, this project has legs! (IMG:style_emoticons/default/laugh.gif)

Nice!

I'd have been messing with kitten bellies when they climbed like that.

You didn't explain WHY phasing is important on German CV joints.

Phasing allows proper axial movement of the joint to account for axle length changes during suspension operation.

Most CV axles have a double sphere outer joint (that has no axial movement) and an inner joint that has 2" of in-and out" available. Often these are 3 lobed and called "tripod" joints.

The German design appears to be STRONGER as when folks get serious that is the direction they change too.

High end rock crawler stuff is almost always German style.

Now, you get an old school driveshaft (with standard u-joints) "out of phase" and the vibration gremlin you create will dive you "bat-shit" crazy.

Jaguar had multi-piece driveshafts with an elastomer between two fixed tubes for NVH.
Had a car once that 3 other shops tried to fix (to the tune of 5K worth of un-needed work) that twisted its driveshaft, and the u-joints no longer lined up.

Customer didn't believe it was just a driveshaft so I replaced it with another out of one of the "For Sale" cars at this shop and it SOLVED the "can't see out of the rearview mirror" vibrations.

An out of phase old school drive shaft is un-drivable.

An out of phase German shaft will still sort of work until it EATS the CV joints.

Most old school drive shafts are single piece and unless you actually twist the tube you cannot achieve out of phase. The problematic ones are either two piece like the Jag OR have a splined section (for axial movement) that someone didn't index before they took it apart.
The last one is SUPER COMMON to happen!

EDIT: Have another thought...
If you do the "floating axle" like Chris did there might be enough axial freedom that phasing the German style junk might be unnecessary!

I'd have still corrected it too but...
Maybe you didn't have too!

The whole "Floating Axle" thing is DEFINITELY Ninja approved! (IMG:style_emoticons/default/ninja.gif)

One piece of information.

The plugged holes in the floor pan are used in the factory to hold the stamped floor pans to the assembly jig. There is a cam that sticks up from the jig and can be turned, kinda like an IKEA furniture lock cam. While on the jig, the stamped panels are all welded together and the plug cam is turned to release them from the jig.

This comes from an old 356 assembly video that Al Zim showed me one time. Karmann built bodies like that for years.


One question on the pedals.

How do you get the master cylinders off the pedals if you have to replace one? Do you completely unbolt the pedal assembly and take it out of the car?

Are you going to weld up the hole for the factory master cylinder?


I love the videos.. and I love the addition of the cat updates. Keep them coming.

Thanks!

Chris @tygaboy I phased these deep plunging 930 cv's (McKenzie Offroad Perf) and painted some gold colored dots to indicate the opposite ends;
2 dots = fat/wide section & 1 dot = skinny/narrow section... then index with a straight-edge. This reminds me that "It's done" way after the boot+flange+ lube is all set in place ...no re-thinking of missing an install step.
Also if using 930 CVs make sure that the outer circumference edge with the 'Groove faces outwards;
1 side faces trailing arm/ 1 side faces trans output flange.

[Maltese Falcon]

I also use a small length of (stranded) 12 or 14 ga. wire around the end of the cv boot, a bit of lube on the (300m SwayAway) axle...and using both hands simultaneously >>simple tugs on the wire brings the boot over the spline area and into place

Look at all the cool info, helpful hints and myth busting that gets shared on this awesome forum! (IMG:style_emoticons/default/smilie_pokal.gif)
Thanks @Maltese Falcon @technicalninja @ClayPerrine

I'm going to add these clarifications to next week's episode. with full credit, of course!
Thanks again.

@ClayPerrine - Well, not completely remove. I use a section of flexible hydraulic line between the M/Cs and the chassis that enables the pedals to be unbolted and slid back to allow removal of the M/Cs. It's not fun but it worked when I changed out the clutch master on my LS car.
And yes, the factory M/C holes will be closed up.
Great to hear you're enjoying the kitties!

Pedal assembly in!

I've been "owned" by cats since I was 15.

Got subjugated by a male red tabby I named Maxx who showed up "out of the blue".

The very best cats have been the ones who magically appeared out of nowhere...

It was when I saw him ride a neighbor's dog like a bull rider that I thought cats are super cool.

But, when I saw him do that for a second time, to the same dog, that I knew cats were for me!

He did it "because he could" for sport!

I'm in for a "sporting" red tabby anytime...

Had the same sort of thing happen 11 years back.

Austin (middle son) had gotten a red kitten about 3 months old that he left with us for a ski trip. He named him Mufasa. Mufasa was asleep on my wife when I found "HIM" on the back porch!
I yelled at him "Mufasa, how did you get out" and he hauled ass.
Ran back into bedroom and found Mufasa still asleep on the wife.

It was a second one, same age and coloring, just showed up!

This kitten adopted my youngest son, Michael.

We called him "Echo" because doppelgänger or mirror image was too hard to yell...

[tygaboy]

Someone said I should check the level of my master cylinders...

[tygaboy]

Both axles in and looking very cool! Next, I need to work out the bracing for that rear trans mount "pivot link" mount - that's what you're seeing with those two V-bars. I wish there were a more elegant solution but this one likely makes the most structurally sound sense.

On a different note, one of my buddies suggested I work some Japanese parts into the build "so it has full Axis representation..."

[technicalninja]

I vote for a Denso AC system!

The old name was Nippon Denso

This translates to "Japanese Electrical Device" or "Japanese Electrical Motor" depending on the translator.

Trust the Japanese to "obviously" name their companies...

[tygaboy]

Oil cooler solved! What? You think I should do something more elegant? (IMG:style_emoticons/default/happy11.gif)

Another happy coincidence! Porsche trombone oil line fittings are the same as the Ferrari system. One less thing to chase down. Look closely, it's connected - well, one end anyway.

I like the location, but you might want to connect the outlet to something.

BTW, that oil filler reminds me of old indy car pop-off valves.
