Reducing the starting torque

The starting torque can be reduced by installing thinner wear plates.
Please note: increasing the gap between lobes and wear plates reduces the volumetric efficiency.

Increasing the gap by installing thinner wear plates

Gap increase



+ 1 mm

On gearbox side and cover side:

Replace the wear plates PFL.A017 (6 mm) with PFL.A017.T1 (5 mm)

Gap increase



+ 0.3 mm

On gearbox side and cover side:

Replace the wear plates PFL.A017 (6 mm) with PFL.A017.T2 (5.7 mm)
