约翰迪尔6B-954拖拉机，采用约翰迪尔PowerTech发动机，扭矩储备达22%。全系标配涡轮增冷，进气温度，进气密度，使更充分，动力性能。PowerCore空气滤清器可达到99.9%的去尘效果，为发动机提供干净的空气，寿命。鹤壁约翰迪尔发动机气门弹簧价格 如果发动机有很重的负载，而负载在起动时不能够被分离，则需要气压调节阀的设定以足够高的速度来起动发动机。空气的损耗量直接关系到速度；气压也与发动机飞轮的转速有必要的联系。如果有必要适当的曲轴速度以起动重负载发动机，气压调节器可以被设定到超过760千帕（110磅-平方英寸）。在适当的设定下，空气起动发动机可以尽快起动重负载发动机，其起动时间将尽可能接近起动轻负载发动机的时间。 也就是说该机不能发动原因从大的方面而言与三个因素有关：，控制电路正常即电控部分正常；第二，机油压力正常；第三，燃油供给及燃油压力正常。因此，在进行此类故障的检修时必须要三方面结合，综合考虑,缺一不可。否则就会走弯路。 CAT水套水冷却液温度计：这个仪表指示CAT发动机冷却液温度，冷却液温度变化和加载有关，这个温度不允许超过压缩制冷的沸点温度。CAT发动机运行时温度范围是88-100℃（190-210℉），在特殊情况下温度可能比较高。CAT发动机使用比较低的英热单位值燃料时，温度会在110℃（230℉）,而余热CAT发动机冷却液温度会达到127℃（260℉）。 KEY PART NO PART NAME QTY SERIAL NO 0 0 1 REMARKS 1 AT185696 ALTERNATOR 1 24V, 45 AMP, (SUB FOR AT173624) TY24322 ALTERNATOR 1 (A) 2 R48808 WASHER 1 3 R501486 PULLEY 1 4 R64525 THRUST WASHER 1 5 T158584 FAN 1 6 19M7867 SCREW 1 7 14M7296 FLANGE NUT 1 8 R64525 THRUST WASHER 1 9 19M7812 SCREW 1 Removing Piston Pin Bushing on Tapered Pin-End Rod 1. Select JDG953-1 Driver (A) and JDG953-2 ReceiverCup (B) from JDG953 Connecting Rod Bushing Service Set to remove bushing (C) from tapered rod. 2. Slide driver into one side of rod bushing. Turn driverbuntil taper on driver flange matches up with taper on the bushing. 3. Install receiver cup onto opite side of rod bushing. NOTE: Stud in cup keeps rod properly located on the cup. IMPORTANT: If bushing is heily worn, the driver may contact the ID of the rod bore. Be careful not to damage the rod bore. 4. Using hydraulic press, press bushing out of the rod until driver and bushing fall into receiver cup. 5. Clean, inspect, and measure ID of rod pin bore, as described later in this group. 5. Release fan belt tensioner (B) and remove fan belt (C). 6. On Four-Valve Head Engines: If needed remove fanbelt tensioner and bracket as an assembly. 7. Remove alternator (D) and alternator mounting bracket.(See REMOVE AND INSTALL ALTERNATOR in Group100.) 8. On non-auxiliary drive engines, remove tensionerbracket. 9. Remove water pump (E), if desired. (See REMOVEWATER PUMP in Group 070.) 10. Remove fan pulley (F). 11. Remove crankshaft pulley or damper (G). (SeeREMOVE PULLEY OR VIBRATION DAMPER ANDPULLEY in Group 040.) 12. Remove unitized front oil seal-wear sleeve, ifequipped. (See REPLACE FRONT CRANKSHAFTOIL SEAL AND WEAR SLEEVE in Group 040.)
