Captain Obvious

Hahaha!! No, I had never seen that one. Oy, So someone actually has that on their arm? It's only funny because it's not me!!

Haha!! No kidding!! I'm not sure I would! No hurry on the sockets my friend. I'm off the road until next spring. And we all lived to tell the stories. Not only was the map on a napkin, but it was scribbled down AFTER the crawl started! Now THERE'S a recipe for success!

Haha!! Nice grip! I don't think of car tools when I see a grip like that.........

Brass sometimes tarnishes to a blackish color. Maybe they are brass, but are just a little discolored?

Take the red LED out and replace it with a normal incandescent bulb and see what happens.

Last summer I flew 1000 miles to a town I had never visited before to spend a long weekend with a number of Z car people I had never met. Heck... I even jumped blindly into cars with some of them and their wives!

You made me go look that one up. Wow... That describes me to a T. Never knew there was a name for it!!

Charlie, When I first got my car, my driver's side seat belt webbing was badly frayed. I have since replaced the whole assy with a donor in better condition and then took the old one apart to see what made it tick. With that in mind, I think I have a plastic side cover sitting in a box that I would be happy to donate to the cause if you're interested. If so, shoot me a PM and we can chat.

What he said. There is no key. As for the splines, I believe they did use the same spline dimensions in both the middle of the shaft and at the steering wheel, so you could reclock the steering wheel if necessary. I don't know if I still have the parts here to double check that, but I'll look when I get a chance and see if I kept them. But that really shouldn't be necessary... Take a look at ST-6 of the 1972 manual, On the lower left, they talk about a punch mark that is supposed too be upwards when the wheels are pointed straight ahead. Maybe you can eyeball the tires to straight and then put the shaft back into place such that the rubber coupler lines up with the steering rack?

Been so long for me that I don't have any memorable info to provide, but I can provide moral support. Good luck and hope it goes smoothly!

Another shot of the finished product:

I cut the splines in on a machine called a "metal shaper". When you mention shaper, most people picture a wood shaper, and it's nothing like that. It's a machine with a ram that moves fore and aft. Cuts a little bit on the forestroke and then drags (but doesn't cut) on the backstroke. Picture the motion of a hand held hacksaw. Vooopah - Voopah - Voopah... You cut one groove to depth a little at a time, rotate the part the correct number of degrees and cut the next groove to depth. Once you have gone all the way around and cut each individual groove, you're done. Shapers are the machines from a bygone era and have been mostly replaced by milling machines. The saying amongst the machinist community is "You can make anything you want on a shaper... Except money." However, there are some jobs like splines and slotting, there's nothing better. I just like watching it work. It's memorizing. Fore and aft. Clickety-clack. Fore and aft. Clickety-clack. A little wisp of smoke off the cutting oil... Here's a couple pics of the setup. This is a pic of the cutting tool that gets rammed into and out of the blank workpiece. The shape of the small cutting tip has been ground to result in the proper groove shape to mate with the male spline on the steering column: Here's the tool mid-stoke inserted into the blank. The round device with the holes in it is called a "collet spinner" or an "indexer". The holes provide the ability to rotate the blank an accurate number of degrees: And here's a pic of the overall setup. Collet spinner on the left side clamped halfass in the shaper's vice, and the shaper on the right side with the ram at about mid-stroke:

Thanks guys! Yes, it was a difficult install. The problem is that the mounting spline dimensions from the 90-96 300ZX is different than what we have on our first gens, so I made an entire new mounting hub for the wheel, cut off the original one, and welded my replacement into it's place. Lot of work, but the end result is that the wheel is in the same location to stock and it's also about the same diameter as the original wheel. So it's not a fancy small diameter racing wheel, but that wasn't what I was after. I wanted something that was leather and had a thicker feel to it, but didn't look aftermarket. I wanted something that it "looks like it belongs", and I like the fact that it came from the Z family. Unfortunately it's not an easy adaptation. Here's a thread about the install with some additional pics:http://www.classiczcars.com/topic/46609-steering-wheel-300zx-240sx-wheel-into-first-gen-z/

I adapted leather wheel from a 1990 300ZX. Significant project and therfore not much help to the OP, but since people are showing off their wheels, I figured I would play.

Those are not the droids I'm looking for.

I hope you know that a post like that absolutely must be followed up by pictures of you modeling said contraption. There's no way you can toss that out there without supplying pics of it in situ.

Haha!! Just like a big puppy dog!! Love it! Sp welcome to the spindle pin club. Now that your hazing is complete, you're a full fledged member. Wish I had the tools you do! Hey... Is that a welded stack of military grade nuts as a spacer?

You know your car fell over, right?

It's an RPM controlled "fuel cut". Take a look at page EF-12 of the 76 FSM. It describes the operation there. Basically, if you take your foot completely off the gas when the RPM's are around 3200, the ECM stops injecting fuel. Once the car slows down to the point where the RPM's drop below about 2800, the ECM starts injecting fuel again. That's the "smoothing out" you feel.

Now THAT'S a press!! I think I just heard my wimpy little 20T press in my shop whimper in fear... More rough back of the napkin calculations: At an estimated 125K psi tensile strength for the spindle pin with approximately 0.69 square inches... It would take about 43 tons before the threaded porting tore off. So you can be confident that building a beefier puller device would probably never have worked anyway and would have been a waste of time. If it took 60 tons to move that thing, the tip would have ripped off long before it started to move. We absolutely DO need to get together for drinks!! I don't know if I'll ever get really close to you, but I am hoping to make it to ZCON 2016 in Toronto next year. That's not far from you, right? It's in Canada after all...

They may think it's a movement! So we're going to veer way off course for a moment... This past fall 2015, I went on a quest. I couldn't find the dump, but I did find: Unfortunately, it is a bit overgrown and no longer open: Nature has started to take over: The church, however, is still vibrant as "The Guthrie Center". https://guthriecenter.org/ And yes... That is a red VW Microbus in the parking lot: Sorry for the detour, and back to your regularly scheduled event.

Haha! Nope. It was a joke. I was just trying to lightheartedly reinforce your input that you mentioned more than once in capitol letters with exclamation points. In the middle of the other side. Away from everything else on the other side. In parentheses. Capital letters. Quotated.

Patcon, Here's some back of the napkin rough calculations to get an idea of just how little meat there was left on that puller... Major diameter of internal 12mm thread - approx. 0.47 inches Minor diameter of external 3/4-10 thread - approx. 0.63 inches Cross sectional area of resulting cylinder between the two - approx. 0.55 square inches When you compare that to the cross sectional area of the threaded portion of the spindle pin (approx. 0.69 square inches), you'll see that the puller is destined to fail before the pin does. And that doesn't even account for the stress risers or the fact that the spindle pin is made out of a better grade of steel than the all-thread used for the puller. If you were to use a good quality 1-5 acme threaded rod for your puller, your minor diameter of the acme threads would be approx. 0.780 inches and the resulting cross sectional area for the cylinder would approach twice the area of the spindle pin tip. And that means that if the pin doesn't budge, at least the pin tip will tear off before the puller fails.

wheee, I'm sure that with perseverance and the unbeatable combination of smarts, technology, and brute force, you will win this battle. Good luck! Zed Head, They call that technique a "shrink fit". One of the places you've probably seen it is with ring gears that were shrunk onto flywheel castings. Heat the gear and drop it over the flywheel blank while hot. Once it cools, it locks tight. In more recent days it seems cheaper to make the whole flywheel out of one piece instead of a separate ring gear though.

Chickenman, Other than some length of vacuum tubing, he's already got all the parts he needs right there already on the car including the ability to screw adjust the amount of idle boost desired. As described in post #11. Captain out.
