Lubrication system
Oil line 1
Ensure that the soldered joints present no capillary cracks. Blow the oil line with compressed air to check whether the pas-
sage is clear. Also check that there are no friction points on the oil line. Always replace the seal rings with new ones
(8x12x1).
O-ring 2
At each oil change, also replace the O-rings.
Oil pump cover 3
Check the inside for signs of seizure caused by the oil pump rotors and if necessary replace.
Oil pump shaft 4
Place the shaft on a flat surface and check its offset.
Oil pump gear 5
Check the teeth for wear. The roller seat should not be damaged.
Oil units 6
Clean the two oil units with low-pressure compressed air.
O-rings 7
Check their porosity and if necessary replace them.
Oil pump rotors 8
Insert the oil pump rotors in the crankcase and check them as shown in the figure on the previous page. No particles
should stick to the rotors.
