Hello,
I have bought a new BUKH DV7 marine diesel. It’s based on a Farymann 18W engine.
I’m really confused about the lack of a proper air filter – it’s just an empty can on the air intake.
The can has a strainer with big holes (sq. mm) for air inlet. Anyone knowing about it ?
I have never heard of marine engines without air filter. Experience of Bukh DV7?
Regards,
Tommy |

My Bukh DV8 has no air filter. It is 23yrs old, starts easily and runs nicely. |

My Bukh also has a strainer type air filter. Good for keeping out nuts and bolts but not dirt and grit. I intend to replace it with a car air filter. Housing and filter about $30 from the auto shop.

Many of the older marine engines had this can, some just had an intake pipe. This can is a silencer. That is it cuts the noise of the air rushing in. Suprisingly it does a good job. If you think about it, your engine if working on the water and not in some drought ridden wheat field or construction pit where dust and dirt is a factor. If you fit an after market air filter system, make sure you have not added any air restriction. |

My dear old Bertie the Bukh (DV20M) has suffered a minor upset. Does anyone know where I can find the Torque loading figures for the Cylinder Head and the inlet and exhaust valve clearances. |

Tim,
The Torques are;
Cylinder Head 9.5-10.5 KGM (68.7-75.9 FT.LBF you will probably require a special tool which I think is a 19mm crawfoot wrench to tighten the head
Valve clearances;
Inlet 0.25mm (0.01 inch)
Exhaust 0.30mm (0.012 inch |
