The BAD AST Project - Faze II

[astroracer]

After working on the yard tractor every night this week I finally got that wrapped up last night. Pulled off the mower deck so I could replace the brake switch activator. This is a very thin stamped steel piece that pushes on a switch when the brake is depressed. The tractor won't start if this is broke and the damn thing breaks at least once a year... While I had the deck off I sharpened the blades, cleaned it all up underneath and doused it with silicone spray. The silicone really helps keep the cut grass from loading up under the deck. I have had zero problems with a plugged mower deck since I started doing this years ago. It works really well.



Anyway... I got that finished up early last night so i jumped on the computer and started modeling the 10" fan and designed a shroud for the trans cooler. here is a pic of the cooler in position on the front side of the radiator. I spaced the cooler out from the radiator a couple of inches to hopefully not block too much flow.

This is a pic of the shroud. Because the fan is bigger in diameter then the cooler is wide I added some closeouts at the top and bottom to help contain the air flow and direct it thru the cooler.

You can see the angled closeouts in this side view

The shroud wraps around the cooler on the back side and will seal it up very well. There will be a bit of blow-by but 95& of the flow will go thru the cooler.
The fan mounting face.


Here is a shot with the fan in place.

I also modeled up some verticle brackets to mount the trans cooler and shroud to the front core support. I need to verify some dimensions for those before I do the details.
I hope to get started building this stuff this weekend.
Thanks for looking
