The following steps outline installation and setup of the recommended optional brushless power system:
• In order to provide the most secure motor mounting, and proper clearance for the forward bearing cup in the
main frame, it will be necessary to install the Park 370 brushless motor’s (EFLM1000) included “Adapter Ring.”
• After installing the adapter ring, it will then be necessary to remove the stock brushed main motor from the
main frame in order to trial fit the brushless motor to check for proper placement of the pinion on the brushless
motor’s shaft.
Note: Before removing the stock brushed main motor, we suggest that you check the gear mesh of its 9-tooth
pinion and the main drive gear, in multiple places on the main drive gear, for reference. This is approximately how
you will want to set the pinion and main gear mesh after installing the brushless motor and the 8-tooth pinion.
• Once the stock brushed main motor has been removed from the frame, temporarily install the Park 370
brushless motor. Then, using the 8-Tooth Pinion Gear (EFLM1949) and main gear for reference, mark the shaft
of the motor (using a marker or tape) at the point to which the pinion gear should be press fit onto the shaft
to provide adequate gear tooth contact of the pinion and main gear. It is important to install the pinion on the
motor shaft so that it will always offer full contact with the main gear teeth in order to promote the best power
transfer and to prevent uneven and/or accelerated gear wear.
