KPG 27 gearbox, 5.2: 1with pinion ø3.17 shaft, without flange, Kontronik # 03752
Kontronik offers the KPG27 gearbox ready mounted on their FUN 500/600 engines. But they can also be retrofitted on all motors with 3.17mm shaft diameter by means of adapter flange.
The scope of delivery of the gearbox includes the motor pinion, which must be glued to the shaft by a Loctite adhesive (eg 648 or 2701). The bond can be solved with heat again. The scope of supply also includes the needle-bearing planets and a basic lubrication.
The matching adapter flange must also be purchased when retrofitting a direct drive to gearbox.
The KPG27 should be used with power from about 400Watt, as compared to the KPG25 a 6mm output shaft is used.
