Engine Block Processing

Transcription

1 Engine Block Processing Reception of parts for treatment. Washing the crankcase before treatment. The crankcase is washed twice more during treatment. Crankcase check-up before treatment. Crankcases ready for treatment. Piston wear out check-up before treatment. Line boring of the engine block. Cylinder liners are made of high quality alloys ( km guarantee after liners built in) Cylinder liners check-up before placement in the block. Cylinder liners placement. Cylinder liners leveling Line boring Automatic drilling machine used for line boring of engine blocks Surfacing of Diesel engine blocks and blocks with cylinder liners built in Honing controlled and monitored by computer Tottler F88S Surfacing

2 Rottler F88S Line boring More than 3000 assembly line operations are controlled and monitored by computer Washing and cleaning of engine oil passages after treatment Computer control after treatment displays the accuracy of measurements on screen Painted crankcase after treatment. WE PROCESSED Packing and delivery FIAT engine block Mercedes engine block Komatsu engine block Locomotive engine block

3 Engine Crankshaft Processing Reception of crankshaft for treatment. Washing the crankshaft before and after treatment. Crankshaft check-up before treatment. Engine crankshafts are magnetic flux tested for any cracks. So-called plugging at the crankshafts, which can be cleaned. Alignment and distortion testing Processing of crankshafts from the cargo vehicles program Crankshaft welding up Straightening of the crankshaft on special presses Engine Crankshaft Processing Processing is monitored by measuring rod and computer,so that errors are minimal. Micropolishing by very fine grits Big end connecting-rod control Small end connecting-rod control and processing. In Diesel engines, tolerance testing between bolt and small-end bush is mandatory.

4 Crankshaft firmness is measured before and after treatment Control of the crankshaft Small end connecting-rod processing Once processing has ended, the crankshaft is micrometer tested ensuring maximum accuracy.

5 Engine head processing Reception of parts for treatment. Engine heads before treatment Disassembling of engine head, verification of whether the valves and reins are worn-out, and engine head height measurement. Washing and sand-polishing of the head to restore its original condition. Engine heads porosity testing under the working temperature and operating pressure (6-8 bar). Removal of old and new valve guides installation Reaming of valve guides to achieve necessary tolerance between valve stem and valve guide. Detailed check-up (control) of valve stem Welding Welding Line boring of engine head cracks and preparation for welding Welding of engine head cracks using latest MILLER device

6 Welding of engine head cracks using latest MILLER device Weld treating and testing Pre-chamber bearings processing. MR Service successfully deals with 90% of cases of serious damage, for example damaged valve lifters and injector bearings or any other cracks that can disrupt the normal function of an engine. So-called 'thorning' of camshaft bearings Valve bearings processing Valve bearings processing cargo vehicles program Engine head leveling Surfacing of gasoline engine heads. Engine head surfacing by grinding stones, a knife or a special diamond. Engine head ready for assembly. Valve's worn-out testing, shortening. Engine head assembly. Valve testing by vacuum meter Valve clearance adjustment essential for all vehicles Assembled engine head after processing from the cargo vehicles program
