                                     Repair of the engine

                                           Dialogue I

      Chief Engineer: We want your shipyard to undertake some repairs to our diesel engine.
      Repair Engineer: O.K. What repairs do you want us to make?
      Ch. E.: There is a list of repairs to be done. Here is a copy for you in English.
      R.E.: That's good. Thank you. What shall we begin with?
      Ch. En.: Let's start with the cylinder liners of two- stroke engine. We need 6 cylinder lin-
ers. All the dimensions, material and working of the material are shown in the drawings.
      R.En.: They will be very helpful, thanks. As to the material it is cast iron with Brinell
hardness of 180–190 units, I guess.
      Ch.E.: You are quite right. But will you please, find the rings with Brinell hardness fig-
ure five units higher.
      R.En.: I see. No problem. What's the next to be discussed?
      Ch. En. The next item is bearings. The main bearings should be rebabbited and bored out
and then fitted in places. The dimensions and shapes of the bearings should be as close to the
old ones as possible.
      R.En.: That's clear. Anything else?
      Ch.E.: Yes, Piston heads must be ultra sound tested and if there are some cracks there,
the cracks should be cut out and welded. Is it possible?
      R.En.: Yes, certainly. I suppose we'll be able to do welding right on the spot.
      Ch.E.: That's suit us. Besides, we want you to inspect the fuel oil pumps and if necessary
to replace the plungers and liners.
      R.En.: Well, I see. What else have you got in your list?
      Ch.E.: Oh, I've put down all the items.
      R.E.: O.K. Don't worry about repairs then. Everything will be done as it should be.

      Notes:
      … right on the spot – … сразу на месте
      … as it should be – как следует


                                           Exercises

      I. Answer the questions.
      1. How many cylinder liners did the chief engineer need?
      2. Where were the dimensions shown?
      3. What was the working of the material (спецификация материала)?
      4. What kind of repair did main bearings require?
      5. How should the piston head be tested?
      6. What did the chief engineer say about the cracks?
      7. Do the fuel oil pumps need repairing too?
      8. Where could the repair shop do the welding?

      II. Ask questions to.
      1. You should use babbit metal containing not less than 83 per cent tin.
      2. The oil grooves should be scraped out in the same way as in the old bearings.
      3. The dimensions are shown in the working drawings.
      4. We want to have the exhaust valve removed and dismantled and its condition checked.
      5. We'd like to discuss prices.
      6. Pistons are usually made of steel.
      7. The repairs will be completed in about a fortnight (2 недели).
