I need a timing wheel cut out. I will have it drawn up in SolidWorks tonight, but here is a general idea of what I need. I need to make the crank sensor on my 350Z engine be able to be ran on the front of the engine. Sooooo, I need the stock trigger wheel on the flywheel reproduced but in a diameter of about 6-7" instead of 12".

Here is a pic of the timing wheel on a JWT flywheel. It's 36 evenly spaced slits, with 6 of them missing, in pairs. Looking at the pic it will make sense. 10 slots, 2 missing, 10 slots, 2 missing, etc. I would also need 3 holes drilled in the center to bolt it to my ATI pulley, but that will be the easy part. Material would need to be 1/8" mild steel or similar thickness.

Anyone up to the task?

 

Just drew this up in SolidWorks. 3mm thick (not too strict, it can be slightly thicker or thinner), and 200mm in diameter.

 

I wouldnt do it on a plasma table. Either waterjet, lasercut or machined.

 

x2 You may run into issues with drive ability. Or just starting in general.

hall sensors require small tolerances between the wheel so plasma is out of the question. I cant really see any mounting holes other than the middle, so you might want to think about that cause it will flex around with different harmonics (unless you are mounting it like the flywheel pic). If it is going to be a big plate like your model then the question of balancing comes up. Why arent you looking into tapping the cam gears and crank pulley for this, it seems easier?

 

I work at a cnc machine shop where are specialty is some of thr hardest jobs in the world and we use most of your usual metals and some of the worlds strongs metals. Send me a email with the dxf file or cad file and i will bring it in and put it on my geopath or solidworks. 3.0 program an see how difficult and the run time and how much it would cost let me know what kinda matiral will be needed and i can probally take care of it no problem. Here is my email 408gsxr750@gmail.com and my name is ken

 

Yeah, I thought of how imprecise a plasma can be as soon as I posted the thread. Just forget I mentioned it

It is a hall sensor, and this design I have made is exactly like the factory trigger wheel (thickness, width and depth of teeth), just smaller diameter.
The mounting holes are the 3 slots, as I will need some adjustability. It will be bolted directly to the hub of my ATI SuperDamper, using all 3 bolts. The center hole is just for crank bolt access

Normally cam gears or crank pulley would be better to just drop magnets into, BUT, its a timing chain setup, so I'd have to drill and machine the chain case to accept the sensors. And I don't want to drill into my ATI pulley myself, nor pay ATI $300+ to do it for me.

I will send you the DXF file shortly, let me know if it looks right to you. I'm not sure if the SLDPRT -> DXF conversion is correct.

 

Well, it looks like no one can accept a SolidWorks file to build off of, so I'm downloading AutoCAD and I guess I'll teach myself that enough to make this part.

Anyone up for a SolidWorks -> AutoCAD conversion before I go through that?

 

I got a water jet shop here that i think he can use your file ill try to call him tomorrow.

 

Wire edm

 

What?

 

Search it up. Wire edm. It uses a brass wire and discharges electricity to cut the part. This is a pretty simple job for a wire edm.

 

if you want it ran on a end mill send me the file. pm me for the email.
