Pyro 650-103L, 550SX Edition
Modifying the Logo 550SX to fit
the Kontronik Pyro 650-103L

Parts Needed
•Mod 1, 106T Main Gear- MIK4621
•Mod 1, 11T or 12T Pinion- MIK4635 or MIK4636
–Note: the above parts are for the 600SX, which has a
thicker main gear and matching pinion
•(1) 6x13x5 Bearing- can use MIK4521 (two come per
package)
•(1) 6x9x0.2 Shim

Step One- Cut Motor Shaft
The motor shaft on the Pyro 650-103L needs 8mm
removed from the end. This is to prevent the shaft from
damaging and interfering with the installation of the
battery.

Step One- Cut Motor Shaft
•Always protect the motor from metal particles.
•Add chamfer to end of shaft.

Step Two- Install Mod 1 Main
Gear
•If you have previously installed the Mod .7 main
gear in your 550SX, please remove it along with the
counter bearing components.
•Remove the auto hub from the Mod .7 gear (if
installed) and install in the new Mod 1 main gear.
•Follow the steps in the manual for installing the new
gear with the appropriate shims.

Step Two- Install Mod 1 Main
Gear

Step Three- Install new bearing
in Counter Bearing Support
•The counter bearing support on the motor side is
used on both the 550SX and 600SX models. The only
difference is the 550SX has a bearing with a 5mm ID
and the 600SX has a bearing with a 6mm ID. Since
the powerful Pyro 650-103L has a 6mm motor shaft,
the appropriate bearing must be installed.
•Carefully press the existing bearing out of MIK4714.
This is easily accomplished with a simple vice and
correctly sized socket. Of course if you have an
Arbor Press, this is more precise for installation and
removal.

Step Three- Install new bearing
in Counter Bearing Support
•Insert the new bearing (6x13x5) in the existing
location and press until fully seated.

Step Four- Install Motor
•Loosely install the pinion on the motor shaft and
install into the frame with the counter bearing
support. Follow the Logo instruction manual for
proper sequence of installation.
•Remember to add thread lock to appropriate
screws and check to see the motor wires are not
rubbing against and components.

Step Four- Install Motor

Step Five- Adjust your settings
and go fly!
•Please adjust your throttle settings per the new gear
ratio and motor kV. (the motor kV is 1030)
•Enjoy your new Pyro motor!!!
