2 stage port relief valve change New 2-stage port relief valve function (1) Neutral - When Hammer/Shear selection switch is off, relief valve maintains high pressure setting. (2) Hammer(1 way) - When Hammer selection switch is ON and X1 uses 1way, releif valve goes to low pressure setting due to pilot pressure. (3) Shear(2 way) - When shear selection switch is ON and X1 uses 2way, releif valve goes to high pressure setting due to pilot pressure off.

Double load check change There have been some cases reported where the operating power of attachments (Arm, Bucket, and Option) has been down and the operating speed of attachments has been slow. This is caused by the wear of double load check valve. 1. The shape of double load check valve has been changed to improve the resistibility of wear. 2. The heat treatment to manufacture double load check valve been improved. **After changing to the new one, there was also problem that the new one can give damage to the block. Finally decide to use old one.

Main components 1.The most advanced Volvo engine controller, EMS2, will be utilized to provide the highest level of electronic features and to enhance reliability. 2.The IEGR(Jacobs system) creates a small second exhaust valve lift. This extra lift feeds exhaust gases back into the cylinder during the inlet stroke to reduce NOx. 3. Common Rail Whereas in conventional diesel engines injection pressure is generated for each injector individually, a common rail engine stores the fuel under high pressure in a central container (common rail) and delivers it to the individual injectors on demand. Benefits of common rail injection are reduced noise levels, stronger performance, improved emission control and greater efficiency. 4.The new high-pressure solenoid diesel fuel injector.(BOSCH-CRIN 2nd Generation Injector)
