I have tried using the Slot.it pinion press to mount pinions on NSR King EVO (long can) motors. Since the shaft is only exposed on one end, the other end is damaged as the shaft is pushed into the endbell. How do you press a pinion onto a NSR King EVO (long can) motor?

By damaged, do you mean when you pressed on the pinion it caused a nipple to show on the can end? If so, the motor should still be okay. Test it and see.Scott.....War Eagle River......Tampa, Florida, USA

There is no real difference for putting a pinion on a long can/boxer style motor using the Slot.it pinion press tool versus using it for an s-can or slim-can motor. The end of the motor that has a cap covering the shaft sits in the collar on the end of the pinion press tool. Pop the pinion into the most suitable recessed hole on the pinion gear holder part of the tool and then slowly close the press. There is no direct pressure applied to the motor shaft, only pressure applied due to the friction between the pinion and the shaft as the pinion is being pressed on.

I use a small brass disk that fits loosely inside of the Slot.it press anvil to give the rear end of the armature shaft something to bear against. By doing this, the shaft end will not dimple the bearing end cap. The disk is .055" thick and .218" in diameter. I use a small bit of grease to keep the disk in place when using it. The disk is thin enough to allow the bearing end cap to locate the rear end of the motor center to the center line of the anvil. I believe the disk could be thinner and could be aluminum or steel.
