LUBRICATION

The oil bath provided for the pump drive shaft bearings has a capacity of 0.75 litres
(1.3 pints) and should be topped up when necessary with 10w/40-15w/40 multigrade
engine oil. It is recommended that the oil bath is drained and refilled with fresh oil
about every twelve months.

To check the oil level, remove the filler/dipstick, which is situated on the bearing
housing immediately behind the pump body. Add fresh oil through the oil filler
aperture until it reaches the dipstick level. Refit the oil filler plug securely. Run the
pump for a short period and then re-check the oil level. The oil level should be
checked with the dipstick screwed down into its fixed position.

The oil drain plug is situated at the rear of the bearing housing below the pump drive
flange as shown on Fig 1-1.
