The points for assembly and notes for attention (1) Pay attention to the location of the various parts when the pump is dismantled .The parts which have been dismantled should be arranged regularly (2) As the high machining precision the parts of piston pumps is , especially with plunge、 oil distribution shaft、servo spool valve、Set Plate、swash plate, the parts which have been dismantled should be arranged regularly and carefully. Surface finishing can not have a friction with a hard object in order to maintain the accuracy of surface roughness of parts.
