Onsite Liner Landing Machining

Upper and lower liner landing repairs to heavy industrial and marine diesel engines have been successfully repaired using our specialised boring and facing system. In conjunction with make-up sleeve insertion and the use of liquid nitrogen, many engine types benefit from this service and saves cylinder blocks from scrappage. Extreme wear and damage to Upper and Lower landing seal areas of large generator and marine diesel engines can be very successfully repaired on board and on site without the necessity to scrap the cylinder block. In-situ Machining Solutions have the expertise gained over many years to reinstate damage to these areas of cylinder blocks caused by engine failure, severe wear or fretting corrosion to give ‘ as new’ repair results. Repairs usually take the form of light skimming of the Upper landing seal faces in the case of lightly worn surfaces and where these surfaces are badly worn or landing bores are such that the cylinder leaks water into the crank bays with inevitable damage the crankshaft and mating parts. Re-boring and facing of these sealing surfaces have to be undertaken to allow the introduction of make-up sleeves which are usually a shrink or press fit into the newly machined bores or faces. Where broken parts or fracture occur in these seal areas, our advanced stitching system can be employed to rectify the problem and in conjunction with the make-up sleeve insertion procedure has proved invaluable and a very cost effective repair solution to OEM’ s and equipment owners alike. IN-SITU LINER LANDING MACHINING • Range of equipment from 150mm diameter. • Quality, to OEM design tolerances. • Alignment technique to ensure that the seal faces and bores are machine square and parallel to the axis of the crankshaft. • Design, manufacture and fitting of cast iron and steel make-up sleeve in the event that bores and faces are seriously damaged. To re-establish OEM design sizes. • Selective electro plating and thermal spraying to re-establish OEM design sizes. • Metal stitching of fractures, cracks and broken areas of the cylinder block.
