Electric Mustang Project - Help Wanted

[JohnPi]

I'm trying to gather information for a co-worker. He needs to get the x,y coordinates (math-data) for the bolt pattern of a Ford 5.0L V8, in relation to the centerline of the crank shaft (output shaft).

My co-worker is working on a project to transform his fox-body Mustang from gasoline powered to electric motor drive. He wants to use the current T5 transmission that is in the car. To do this, he wants to precisely line up the electric motor with the center line of the input shaft on the T5 transmission. He's going to make an adaptor plate using the math data to do this. His goal is to be able to drive the car 40-50 miles on a single charge.

Any help, or direction for information, is appreciated.

Um, the bellhousing keys on two dowels 180 degrees from each other, which should be equidistant from the crank centerline. The rest of the bolt holes probably have wiggle room.


Why doesn't he find a junkyard tranny and measure them himself?

Is he going to be using the bellhousing? Or just the Tranny?

 

[Wicked_Sludge]

hes probably going to use both.

its a pretty common way to do the conversion. a plate that bolts to the bellhousing with a hole cut out in the middle, the traction motor then bolts to the other side of this plate and engages the transmission through the hole.

i dont have the info your friend needs, but if it were me i would just trace a template or measure the holes myself.

Thats what I would do too, but sounds like he might be making the part on a CNC mill.

"Why doesn't he find a junkyard tranny and measure them himself?"

It's funny you say this, because that was my first sentence when he asked for the information from me. He told me he already bought an extra transmission to do this measurement, but he wanted to get something a lot more exact. It is a critical alignment between the electric motor and the transmission, so that there isn't any inherent vibrations in the system. The hardest part is not the bolt pattern (which isn't that easy to get as exact as Ford has it), but getting the bolt pattern to align with the center line of the mating components.

It was a little project of mine for CAD class. Got to use our Fancy CMM machine which is accurate to within .001" or so. It's not ultra exact but they have offset dowels so that you can adjust the bellhousing to the crank centerline, and this should definitely get you close enough that they will work.

Maybe I should throw this in the Tech library for giggles and grins..

Thank you very much. I'll forward that along.
