| Key ITEMS
| | Drivetrain 1.18.2009 |
|
| |
|
| <br>
| |
|
| |
|
| *27.25” LONG x 37.25” WIDE
| |
| *Rear wheel axis at 5.625 from most rear surfaces (adjustable down to 4.625 corner brace regime permitting)
| |
| *Front wheel axis at 11.625 from front most surfaces (adjustable ± 2.00”) <br>
| |
|
| |
|
| <br>
| |
|
| |
| *Still need to determine a few hardware items but I think we could use a few PEM fasteners to further minimize fastener system weight
| |
| *We will need to design a few spacers “on the fly” as we determine the best approach while building
| |
| *The 6-hole patterns in the wheels need to be tapped for 10-32 Depth TBD
| |
| *Need to add the stiffener element between the wheels (1/side 1”x1” ext. Al stock is light and will work well and can be welded)
| |
| *Need to cut necessary smaller frame elements from stock
| |
| *Need to design in provisions for front “dummy wheels” biased 1/8” up for roll over protection <br>
| |
|
| |
| <br>
| |
|
| |
| *Need to order the following parts from the shop by tomorrow:
| |
| *2009-wheel-hub (1/8 wheel retainer plate) QTY:4
| |
| *Hub-bearing (just a spacer in the hub for support not a bearing) QTY:4
| |
| *Brkt-wheel-asy-1 (trans/motor mount left front and right rear) QTY:2
| |
| *Brkt-wheel-asy-2 (trans/motor mount left rear and right front) QTY:2
| |
| *Bearing-block (main double bearing holder for each drive assembly) QTY:4 <br>
