Oil and Coolant Pump - Installation

Warning - General - Stabilise Motorcycle

warning

Make sure the motorcycle is stabilised and adequately supported.A correctly supported motorcycle will help prevent it from falling.An unstable motorcycle may fall, causing injury to the operator or damage to the motorcycle.

caution

Before fitting the oil pump to the crankcase ensure the pump internal surfaces have been wetted with clean engine oil. The pump may fail to pick up oil from the sump if the surfaces have not been wetted. This will cause the engine to run without engine oil pressure and will lead to severe engine damage.

Install a new O-ring to the inlet sleeve on the water pump body.
Fill the oil pump with new engine oil, turning the pump rotor as the oil is poured in to ensure all surfaces are coated with oil.
Position the oil pump to the crankcase and insert the water pump inlet sleeve into the opening in the crankcase.
Fit the oil pump to the crankcase, ensuring the oil pump dowel correctly locates into the bolt hole in the crankcase.

caution

Do not use excessive force to insert the dowel into the crankcase. Severe dowel or crankcase damage may result from the use of excessive force.

Using a suitable pin punch, gently tap the dowel downwards into the crankcase until it seats.
Feed the drive chain over the transmission input shaft and fit to the sprocket.
Fit the drive chain to the sprocket on the oil pump.
Support the oil pump drive sprocket and carefully refit the needle roller bearing.

Refit the washer and fixings as noted for removal. Tighten the fixings to 12 Nm.

Refit the oil pump drive chain guide. Install new fixings and tighten to 9 Nm.

Install a new O-ring to the coolant inlet elbow and position the elbow to the water pump inlet. Fit a new bolt and tighten to 12 Nm.

Install three new O-rings to the coolant outlet pipe and position the pipe through the crankcase. Locate the pipe to the water pump outlet. Install a new fixing and tighten to 12 Nm.
