INTRODUCTION 

 

BASIC ENGINE CONFIGURATION: 

The BUKH engine is a four-stroke marine diesel engine with direct fuel injection and the following basic equipment: 

Crankcase with oil pan, one-piece cylinder head with 2 valves per cylinder, forged crankshaft with counterweights, balance 

weights, cast iron connecting rods, light metal pistons, water-cooled exhaust manifold; all necessary pipework  for exhaust, 

coolant, fuel and lubricating oil are fitted on engine. 

A reverse/reduction gearbox with integrated thrust bearing is fitted on the engine. 

 

No BUKH diesel engine is sent from the factory without having been thoroughly tested. 

The tests have shown that the engine in all aspects is working satisfactorily and is generating its full power. 

You will expect the engine to work reliably witout giving any problems, and to achieve this you are asked to follow the 

instructions in this manual. By so doing, you will get the best from your BUKH engine. 

  

If a problem with the engine should arise, we ask you to apply to one of our distributors, who will always be ready to  

help you, having skilled personnel, necessary tools etc., and at the same time you will be sure that only original BUKH 

spare parts are used. 

 

Do always use original BUKH spare parts. 
 

When ordering spare parts from the distributor please state: Engine type and serial number, description and number of 

parts.

OPERATING MANUAL 

Before the engine is put into use you are recommended to get familiar with the placing of the following components of 

engine and gear: 

Fuel oil filter, lub oil filter and air intake filter, fuel lift pump with handle, zincrod in the crankcase and water-separator in the 

fuel pipe (if mounted). 

Where is lub oil poured into engine and gear and where are the dipsticks placed? Where is fuel oil filled into the fuel tank 

and where is the drain plug placed? Where is the main switch?
