More machine shop p0rn, Toda handles my crank

[themadscientist]

Well, here we are again. Slowly but surely I move closer to getting a motor together for the 180; this **** is depressing.

Grandiose plans be damned, I want my god-damned car running again!The block is done, there is a thread about that, now I have the crank back.For those coming in at the 11th hour on this understand that all this iron is flying back and forth between a dinky pacific island and mainland Japan. A very helpful guy at Toda who speaks english has been working this for me, he is a great guy. My crate arrived a few days ago. I built the crate to protect my crank, just like the crate for my block. I will make one for the head when the time comes.

They always pack some goodies in there. Got a phone strap and some stickers. Let's crack it open. They stuffed the box as i did when I sent it. They also mummified it in bubble wrap. The envelope contains the spec sheet for the work; i will go into that in a minute.



A large wrap of butcher paper to keep the crank oiled up. I send things up coated in grease to prevent rust; it's crazy humid here. They send stuff back coated in clean oil, nice.

Fine, I will whip it out. Now, this crank originated from a junkyard motor. The original engine from my 180 is sitting on the floor in the garage. All these parts come from three different motors; it will be a real mutt. This is another reason I am getting all this work done, to make sure these parts like working with each other.



I had the crank dynamically balanced. Toda offers several options for this. They can balance the crank to itself or begin adding pieces to it at successively higher prices. If you want the crank balanced with not just bobweights to simulate the pistons and rods but also the front pulley, flywheel, clutch and clutch cover they can do it. I can't afford that **** though and this motor is not going to be shattering any dynos, I just want it to run strong for 10 years so I opted for the basic balance.



The spec sheet tells the tale on this fugitive from the scrap heap. It was bent slightly, 0.020 mm at the start. Actually not bad IMO for a stock crank with over 100k under its belt that has been chillin on the floor for about 4 years. Toda gave it a whack though and now it is just .005 mm from perfectly straight. That is less than the thickness of a sheet of paper, quite a bit less actually.The front end was out of balance by 4.13 grams, a nickel is about 5 grams. The rear by 1.11, about the weight of a paper clip. It doesn't sound like a lot but at 9000 rpms it gets heavy quick and that can cause vibration, dat bad.The front and rear now balance to within 0.18 grams, think clean dry egg shell.

I also requested that the journals be lapped. They were pretty ugly, a few rust spots. I missed with the grease way back when They could not get all the scarring ground down without an undersize bearing so they did the best they could. i will be talking with Powers about this. I am going to get the F1 black metal bearings and need to check with them as to if the crank is ok, I think it will be. Is it lapped out consistent? How about these numbers...Rod journals 45.46,45.46,45.47,45.46Main journals, why type the same number over and over, they are all EXACTLY 52.96 according to my Mitutoyo micrometer.

This **** aint cheap, that is $500 bucks right there but as I went from journal to journal with the mic saying the same number again and again, and I went across the crank at least four times, I don't regret a thing. Quality costs money and I am willing to pay for it. I might eat ramen to foot the bill but you have to have priorities.

Classy move 'Mad-man' ! That is a very important investment and I'm glad at the fact you didn't cheap-out here, especially seeing the fact that you will have some aftermarket goodies inside the womb of your block. Maybe your story will help some others see that when you want it done right, it's gonna cost. Keep us posted on that puppy. I won't be able to get back into my stuff for at least another two weeks (Cheap customer syndrome) .........

You are spending all this money on your engine, and your engine bay looks like crap. I think it might be the dirtiest engine bay on the forum. I will purchase a can of engine degreaser and mail it to you if that is what it takes, but please clean it up. If not, I will mail you my foot up your ***.

I think that is the way TMS likes it, all the dirt hides the beast inside

thats just what he tells girls to get them into bed.



thats freakin hot.

[sjbsuperman1425]

very nice. and $500 isn't that bad IMO. something i'll look into in the future. plus, you can't beat the price when it comes with stickers

[float_6969]

LOL, I think $500 is outrageous, but at least you know it's perfect now.

BTW, do you know what else would be awesome? If this guy I know would ever tell me how much shipping is so I could send him some dough. Maybe put a little extra cash in his pocket for the trouble?

Totally worth the investment IMO, Mitutoyo micrometers are quality goodness.

Free stickers rock.

[rico05]

I was shocked that it only cost $500. Great deal from a shop that supports actual race cars. Money well spent.

[bentvalves]

Hes in Japan though Imagine shipping costs to the US.

[r34 gtr]

I'm from the south, I'll just pay some hillbilly to do it one quarter as well in his garage for less than half that!

[float_6969]

I'm no math wiz, but I'm pretty sure that equals you're retarded.

[bentvalves]

LOLZ

[mod_mastaz]

LOL that engine bay ROCKS. I love my dirty engine bay too. Keeps it looking "clean" in a sense haha. I'll thread jack this for a sec. =P TMS, you'll probably recognize and probably even be familiar with this engine bay.

[themadscientist]

looks like an S12. Clean pipework too.

[bradt]

I have to agree with Tim, to an extent. I live in Huntsville and machine shops are a dime a dozen. Got my crank balanced and knife edged for a damn good deal at a local shop.

[themadscientist]

Well for one I live in Japan, everything costs more. And two, I doubt billy-bobs machine shop builds professional racing engines to the level of a company like Toda.

[bradt]

Touche,

we have a shop here that does build race engines, mainly for drag though. Their motor work is top notch, but I would definitely bank on Toda having better quality control.

[themadscientist]

If I was back in the states there is supposedly a Nascar engine builder I would look for. Shops on my island suck. They have no torque plates and won't even attempt a simple valve guide removal. Luckily shipping to Honshu is pretty cheap.

[float_6969]

I wonder how much it cost's to ship a motor that is laying in your garage to my house?

[themadscientist]

good question

[r34 gtr]

eleventy billion dollars
