Operation VH45DE 5 Speed adapter plate IN PROGRESS!

[ZX2NV]

Quick update

I expect the hard to get M14 bolts to be ready this friday at the earliest (currently Monday 10th at 10.55pm here in Australia) Worst case maybe early next week.

Will maybe take another 5 days or so to get to Wes

[elwesso]

I didnt realize the stock flywheel had a spacer. Could you measure it for me?

Anyway, im shooting for wednesday or thursday to get this bad baby drawn up. today and tomorrow are gonna be NUTS.

[elwesso]

Started drawing the plate tonight. unfortunately, solid works doesnt have the thing setup for M14 countersunk so we have to do it individually. not a problem just a slight setback.

WHAT I DO NEED TO KNOW: The diamater of a stock TWIN TURBO flywheel. I have to make some modifications so I need to know how big that bugger is.

If you don't hear back on here, I'm sure we could get an answer over on Z31Performance pretty quickly.

[tmorgan4]

Interesting read: http://www.z31performance.com/...meter

Those guys are saying that nearly every Nissan clutch is interchangable (from what I'm reading) and seems that nearly everything comes with either a 240 or 250mm clutch. The guy starting the thread claimed that the overall diameter of the flywheel stays the same with either a 240 or 250mm clutch.

[T45]

I concur. I believe the TT flywheel is the same diameter as the stock Q auto flywheel going from the teeth. The diameter of the NA and TT flywheels are identical with the only difference being in the contact patch on the flywheel itself.

[elwesso]

Ok great information, i'll feed that to my CAD guy. We'll plan on a 260-270mm inner circle for the plate.

[tmorgan4]

Great....some more contradicting info to throw into the mix!

Quote »3. The NA and TT have the same 5 speed transmission model #, same splines on input and output shafts, etc. and the housings are the same except for one small difference. The spot where the starter mounts on the bellhousing on the TT is machined a little differently so that the starter will properly engage the slightly larger diameter flywheel and so that the flywheel teeth won’t scrape the inside of the bellhousing. You can use an NA 5 speed in a TT but you just have to shim the starter out a little with some flat washers and sometimes grind a little out of the inside of the bellhousing so the TT flywheel will fit inside. If trying to use a TT trans in an NA you would either have to grind down where the starter mounts so that it could engage the smaller NA flywheel or just use the TT flywheel, which could be used with TT or NA clutch.The automatic transmission is different for a TT, but the NA auto would still fit in place behind the TT engine. Although, they are different lengths and you would have to use the corresponding driveshaft. Both autos are geared virtually the same but the TT one is built for heavier duty.[/quote]

Wish you would of told me, my gf's dad owns a achine shop I could of had them made.

[midnightsliding]

cant wait to see these out. i might be picking one up if you sell them. depending on how my budget goes. good job wes. keep it going.

[T45]

Thanks Tmorgan. I have been breaking my back trying to get my trans up to my engine for 2 days now and all the time it was the clearance on the bellhousing. You have no idea the anger that was getting to me yelling "why won't you go to your home?"!!!

They are not the same. haha Sorry bout the mis info. That'll teach me to open my uninformed mouth again.

Where's my grinder....

[qsiguy]

.....yelling "why won't you go to your home?"!!!

lol, I say that all too often when I can't quite get something to fit. "Are you too good for your home!!"

Wouldnt you just measure the Dixon one Wes?

I am checking here as we have a few builds going on and should be able to russle up the exact dimensions of both the TT and NA flywheel widths and diameters.

I will also check on twinturbo.net

I believe they are slightly different in diameter but not sure by how much

[elwesso]

The reason is on the dixon plate the bolt holes are realy close to the edge, which is fine for that but I cant use it with the larger head bolts.

[elwesso]

as an update, the plate is about 95% done. Some of the holes didnt line up perfectly, so we have to remeasure them. Not a big deal, so the drawing should be done by early next week.

Here is a teaser of the product. click to enlarge

[sleepersinc.]

wow when you guys get done ill buy one too wes **** this is some perfect timeing on my part in joining nico man

[tmorgan4]

Thanks for doing this Wes. Only concern would possibly be that bottom countersunk hole on the right side. Due to the countersinking it would be super thin and could lead to some cracking but I may be over exagerating how much force will be on it.

I'll buy one ASAP. Hopefully these are available within a few weeks since my engine will be done and I need to get my car running again.

Who is actually using the CAD program?

[elwesso]

Who is actually using the CAD program?

A friend of mine in school, who is a senior engineering design major.

Remember, we're looking at the plate from the side. turn it 90* clockwise, so the starter hole is on the right side, and thats how the plate is to be oriented. The amount of overhang on that is so insignificant that I dont really think its going to matter.

Also, in regards to flywheel spacers, since the VH45 uses flywheel spacers stock, im thinking if we just stack 1 or 2 of them it would be just as good. You can buy them from the factory, but I do need to figure out how much they cost.

[David Steele]

Thats cool. I'm in an entry level CNC operator/machnist apprenticeship .

[SaintlyCharBoy]

If I were designing a similar product, I would define the outer edge based on a center point circle with the center being common to the "cutout" and the bulge for the starter offset from the starter opening.

Is there a particular reason that you went with the almost rectangular shape?

do you plan to have plates flame or plasma cut prior to machining? It would most likely reduce cost significantly

[elwesso]

at least the first few are going to be cut using a water jet.... Im not sure how im going to be mass producing them, it all depends on how things go with the machine shop that does the first few.

The reason we didnt do it the way you mentioned is because on a circle that large its hard to find the exact center. It was much easier to do things in rectangular coordinates. To be completely honest though, im not 100% sure how the plate was measured since I gave it to my friend who really knows his stuff, and he was able to do everything from there.

Having the plates cut out prior to having the holes made seems like a good idea, any suggestions on where I could have that done? What I was planning on doing is having them cut from 1/4 steel plate. That give me a little over half mm to grind off the top of the M14s, but should reduce cost significantly since 1/4in steel plate is cheap.

[Florida240sx]

I'll install on my block. Then grind off the excess Who cares what shape it is if it's functional. Also simplicity. Let me know when it's ready. As soon as you have it fitting send one my way.

[tmorgan4]

Wes...do you already have a shop to cut the plates?

If not, there's a shop with Waterjet capabilities that I've been using recently that is awesome. They're getting a brand new machine next Monday which the owner said can do all sorts of fancy stuff. Their prices are crazy cheap too. If you need any help organizing production on them I'd be glad to help.

I'll have my engine back in a week or so and I've got 2 transmissions I can mock these up on and do any necessary changes. I've got Solidworks at my house and have access to the engineering labs here at CSU.

And I need one ASAP so I'm trying to help as much as I can.

[ZX2NV]

M14 bolts are done Wes and ready to go, I have 120 of them here.

Drop me an email when you are ready and we will get it sorted, Will post a pic of them in a few days when I finish unpacking my stuff (moved house)

Cheers

J

[tmorgan4]

Hey Wes if you need any help paying for all this stuff up front I'm happy to chip in.

[Florida240sx]

Sunday mornin bump I'm tired and about to go play some paintball

[tmorgan4]

Elwesso,

Is it going to be possible to get one of these in the next few weeks?

[T45]

Hey Wesley, I was putting my motor mounts on and remembered that the VH has 2 braces that mount on the side of the block and run to the bellhousing on the trans. These will work on the Z32 trans with a little modification.

I believe there will be 1 hole on the trans that will line up to the brackets. It would be sweet if that 1 hole could just be drilled in the brace and it's done. If it's off then it'll require some heat and a BFH to get the bracket to line up. If you wanted to have some made they could be made out of 1/4" steel and would be plenty strong enough and also cheap to make as it would be just 2 pieces at a 90 degree angle and maybe a gusset or 2. I'll let you know if the factory VH brackets work and if so then you could just buy factory brackets and drill them for a bolt and nut. Just a thought.

[elwesso]

i dont want to do that right now, i dont realyl think its terribly necessary (mazworx didnt think it was)...

ALSO... i have been extremely unsucessful on getting the plate drawn up, I have to get it CMM measured, so if my deal falls through, does anyone have access to a CMM?
