Re: VexPro WCP DS Gearbox Assembly

Hey guys, we just dropped the WCP DS 3 CIM instructions onto the web. The WCD version is being finished up, but since I promised you instructions by the weekend, here's some tips that should get you taken care of.

The major difference between the standard and WCD versions is the gap between the two black transmission plates - the WCD version includes some additional space for a sprocket or pulley to be contained inside the gearbox. This means that before mounting the front plate (step 9 in the standard manual), you'll want to slide your sprocket or pulley onto the output shaft. Check out these pictures (from the upcoming WCD manual) for the necessary spacer layout: 6WD or 8WD.

Note: If using belts, make sure you loop the belt onto the pulley BEFORE mounting the other transmission plate, or you'll have to disassemble it and start over (like Team Copioli did during Build Blitz ).

The front plate goes on with the same Step 9 as the standard manual, with the appropriately longer spacers / bolts, and the rest of the steps are identical. When the gearbox is assembled, install it into your chassis frame using either the Gearbox Bearing Block or the outside half of a VersaBlock. It's probably easiest to mount the gearbox to the VersaChassis tube (or whatever chassis you're using) first, then slide the bearing block over the output shaft and through the chassis, like so.

Good luck, and let us know how it goes!
