You guys are probably aware of the problematic clicking syndrome of the stock WK tranny.

Building a crawler for a guy and he wants to use as much of the WK as possible...

So I came up with a fix:

Disassemble the tranny and take apart the 22 tooth counter gear assembly.

Remove the "slipper" assembly and head for the garage.

Drill four 3/32" holes through both the gear and the slipper plate. Drill these holes from the gear side and center them in the gear.

Once you have drilled the four 3/32" holes, set the slipper plate aside and switch to a 1/8" bit.

Drill through the holes in the gear with the 1/8" bit.

Use four 3x6mm button head screws to re-assemble the gear and slipper plate. Since the holes in the gear should be 1/8", the 3mm screws will pass through the gear and thread into the 3/32" holes.

Re-assemble the tranny and use the compact lil' booger in your next build.

Smaller screws would work better, the screw heads on these 3mm screws deformed the shape of the gear just a hair and the tranny is notchy. A little trimming will fix that. ;)
