High-end full-flange crankshaft suitable for manual Sachs 503 2 AL, 2 BL mopeds.
High-quality, precision-fit full-flange crankshaft weighing 1042 grams, which has proven itself in a wide range of load tests.
This crankshaft was designed for use in engines with a large increase in power.
All balancing holes in the cheeks have been sealed with aluminum inserts for maximum pre-compression.
The solid connecting rod is equipped with a more stable Ø 16 mm connecting rod pin, which is hollow on the inside for better balancing.
In addition, the connecting rod bearings are silver bearings, which have excellent emergency running properties.
The high-end crankshaft is designed for Sachs 503 engines and has the correct length of the clutch-side cheek pin, which is 3.5 mm longer than that of the Sachs 50/2 crankshafts currently in circulation.
Dimensions of the crankshaft:
- Total length of the clutch-side crankpin: 43.5 mm
- Total length of crankpin on the clutch side: 63.4 mm
- Length of 1st shoulder (clutch side): 21 mm
- Length 2nd shoulder (clutch side) 13 mm
- Ø 1st shoulder (clutch side): 15 mm

- Thread (on end face): MF10x1 mm
- Ø crank webs: 85 mm
- Width of crank webs: 30.1 mm
- Ø connecting rod eye top: 15 mm
- Ø connecting rod pin bottom: 16 mm
- Length of connecting rod (center-to-center): 85 mm
- Stroke: 42 mm
- Weight (incl. connecting rod): 1042 grams
- Dimension needle bearing: Ø 12 / 15 x 14.2 mm (axe 12)
The needle bearing is included in the scope of delivery.
The matching bearings and oil seals can be found under accessories.
Installation tip:The transition between the crank webs and the crankpin is provided with a slight radius for reinforcement. To ensure clean spacing, a Ø 16 x 1 mm spacer washer should be used on both the left and right-hand sides; these are placed neatly over the chamfer and are therefore perfectly centered. The other spacers can be used normally with Ø 15 mm.
&Revised version of the previously offered crankshaft with additional slotted connecting rod foot for better lubrication, improved balancing ratio and thus better speed stability.
