Description
Wideframe shaft seals for the crankshaft are available in two different versions:
- Round cutout for Wideframe engines (material thickness of the sheet metal carrier 0.5mm)
- Square cutout for Largeframe engines (material thickness of the sheet metal carrier 0.8mm)
The version with 0.5mm suitable for Wideframe is only available in No-Name quality. The shaft sealing rings fit and there are no problems with braced bearings.
PROBLEM WIDEFRAME MOTORS
The significantly higher quality Corteco shaft sealing rings are (for safety reasons) only available with 0.8mm thick sheet metal casing. If these are installed in a wide-frame engine, the crankshaft bearings will be distorted, which will lead to bearing damage. a) The circumferential bead in the oil seal is pressed flat, which reduces the height of the oil seal by approx. 0.3 mm. The bearings then run freely.
b) The BGM Pro bearing set with special ball bearings. Here the bearing shoulders were turned to size to ensure a stress-free assembly of the crankshaft bearing. The set includes the matching high-quality Corteco shaft seals.
