1 How to estimate Air Cooled Diesel Engine overhaul time Deutz Diesel Engine overhaul time is mainly based on the practical application of its dynamic, economic and dust changes, such as power down, fuel consumption increases, burning oil, oil pressure drop and crankcase blown gas, and even a significant abnormal sound The Air-cooled Diesel Engine overhaul interval is generally 8000-10000 working hours.
2 Deutz diesel engine overhaul before the preparatory work
2.1 to establish the engine overhaul file to do a good job of overhaul before the engine technical status of the record, reported to the competent authorities for approval, and record the diesel engine model, factory number and production date and its supporting models.
2.2 Disassembly tools to prepare (1) maintenance commonly used wrenches and sleeves and other conventional tools. (2) special tools: a with the engine supporting the flip bracket. B Angle indicator for fastening. C Valve adjustment special tools. D Piston and piston ring mounting tool. E filter wrench and so on. (3) material preparation mainly prepared some commonly used gaskets and sealants. We used the sealant for the 703 silicone rubber, back to the day 586 plastic and GY series of anaerobic adhesive.
3 disassembly disassembly after the detection
3.1 Crankshaft journal and bearing tile detection Detection of the location shown in Figure 1, measured 1,2 position a-a, b-b two directions of data and make a record. Crankshaft main journal and connecting rod journal to wear the limit size of 0.3mm. Beyond the wear limit can be grinding. The current grinding level is based on the size of the thickened pad (divided into three: 0.25mm, 0.5mm, 0.75mm).
