Notes
- Axis along the length; 0 is the tip of the extended rear motor shaft. Cross-section 12.0 × 10.0 (Ø12 can with two flats).
- Motor can and back cap 15.4 long, gearbox 9.0 long; the gearbox output face is 30.3 from the rear shaft tip.
- Output: Ø3.0 D-shaft (0.5 deep flat) reaching 10.0 past the gearbox face, with a Ø4.0 bushing 0.72 proud of the face.
- Two M1.6 threaded holes in the gearbox output face, diagonal pair at (±3.80, ±2.80) from the shaft axis.
- Rear: Ø1.0 extended motor shaft, about 4.5 past the motor for an encoder; HPCB terminals 6.3 apart. The same body applies to every HPCB/HP/MP ratio except 1000:1.
- All dimensions are exact nominal millimetres, true size, with no tolerance added.
