PIAGGIO Beverly 300 i.e. - Transmission, Brakes, and Steering Issues

Possible Cause Operation
Misshapen/worn valve seats Replace the head unit
Worn cylinder, Worn or broken piston rings Replace the piston cylinder assembly or piston rings
Worn or broken piston rings or piston rings that have not been
fitted properly
Replace the piston cylinder unit or just the piston rings
Oil leaks from the couplings or from the gaskets Check and replace the gaskets or restore the coupling seal
Worn valve oil guard Replace the valve oil seal
Worn valve guides Check and replace the head unit if required
Insufficient lubrication pressure
LOW LUBRICATION PRESSURE
Possible Cause Operation
By-Pass remains open Check the By-Pass and replace if required. Carefully clean the
By-Pass area.
Oil pump with excessive clearance Perform the dimensional checks on the oil pump components
Oil filter too dirty Replace the cartridge filter
Oil level too low Restore the level adding the recommended oil type
Transmission and brakes
Clutch grabbing or performing inadequately
IRREGULAR CLUTCH PERFORMANCE OR SLIPPAGE
Possible Cause
Operation
Faulty clutch Check that there is no grease on the masses. Check that the
clutch mass faying surface with the bell is mainly in the centre
with equivalent characteristics on the three masses. Check that
the clutch housing is not scored or worn in an anomalous way
Insufficient braking
INEFFICIENT BRAKING SYSTEM
Possible Cause
Operation
Inefficient braking system Check the pad wear (1.5 min). Check that the brake discs are
not worn, scored or warped. Check the correct level of fluid in
the pumps and change brake fluid if necessary. Check there is
no air in the circuits; if necessary, bleed the air. Check that the
front brake calliper moves in axis with the disc.
Fluid leakage in hydraulic braking system Failing elastic fittings, plunger or brake pump seals, replace
Brake disc slack or distorted Check the brake disc screws are locked; measure the axial shift
of the disc with a dial gauge and with wheel mounted on the
vehicle.
Brakes overheating
BRAKES OVERHEATING
Possible Cause
Operation
Defective plunger sliding Replace the calliper.
Brake disc slack or distorted Check the brake disc screws are locked; use a dial gauge and
a wheel mounted on the vehicle to measure the axial deviation
of the disc.
Clogged compensation holes on the pump Clean carefully and blast with compressed air
Swollen or stuck rubber gaskets Replace the calliper.
