3-GEAR MID-MOTOR TRANSMISSION
Dirt and clay tracks don’t usually have the kind of grip as carpet
or artificial turf do, so it’s not surprising to see a more upright
3-gear transmission with ball di; spec’d for the buggy. ;e
higher and shorter transmission gives the DT buggy a higher
center of gravity and moves more weight rearward compared
to the CA Edition. ;is may seem basic, but the chassis
dimensions, rear shock tower, upper arm mount, battery plate,
and wing stays had to be altered to accommodate it, making it a
noticeable change over the original YZ- 2. ;e DT’s graphite-encased transmission also includes a new gear cover not
found in the CA Edition, and it sticks out the top of the body.
;e steel outdrives protruding out of the case transfer the
power to the wheels via steel CV-style driveshafts that meet
12mm aluminum hexes. To help tame the power, the buggy
uses a two-pad slipper clutch,
with standard-style hex-shaped pads, that rides on an
aluminum topshaft, while the
hard composite plastic idler
and spur gear keep everything
smooth and lightweight. One
interesting item is the inclusion
of a thin die-cut piece of flat
rubber that is used under the
transmission case and two
other points of attachment
with suspension. In theory,
this provides an additional
level of dampening and a small
amount of flex to aid in traction
;e 3-gear transmission is taller
and shorter than a laydown type and
helps improve traction at the rear.
Building and Setup Tips
■ When building the shocks, you’ll have to remove the molded pistons off their
plastic tree. Take your time, and remove any flashing. Also, the silicone X-rings will
swell over time when they come in contact with the silicone oil. To extend their life
and make them more consistent, apply some grease that is formulated for silicone
seals, like Pro Tek RC’s Premier Blue.
■ The driveshafts come prebuilt but to help them perform at their best, apply the
included black grease at the joint. A small dab is all you need. Over time, the grease
can pick up dust and dirt, so you’ll have to inspect and clean the joint and reapply
periodically. But the grease will help extend the life of the parts and make them
operate more smoothly.
■ Apply medium-strength (blue) thread-lock to all the screws that are installed
■ The kit includes an 80-tooth spur gear, and that is fine for most modified motors.
But if you race a Spec class like 17.5T Stock, a smaller spur gear will make it easier
to find the optimal ratio. A 72T gear is a good start.
;e two-pad slipper helps put
the power to the ground and
uses common hex-shaped pads.
