provide assistance during maintenance,here is a list of recommendations regarding disassembly and reassembly.以下是关于拆卸与重装的一些建议，对维护机器有所帮助 1.1 Disassembly 拆卸拆卸?Never hit the parts with a hammer or remove bearing surfaces using tools such as a screwdriver,chisel,etc.?不得用锤子敲打零件或用螺丝刀、凿子等工具清除轴承表面?Always use the tapped holes provided for the purpose or specific tools.?尽量使用专门设计的锥孔?Never use a blowtorch to remove the roller bearing inner rings.?不得用吹管清除轴承内环?Use a wheel hub puller.使用拉拔工具 1.2 Reassembly 重装重装?It must be carried out in conditions of strict cleanliness.确保清洁?The surrounding air must be free from dust,metallic particles(no grinding)and if possible,not too humid.工作环境干燥、无尘、无金属粉末（磨屑）?Prior to reassembly,clean all parts carefully.重装前擦净零件?Check the bearings faces and alignments.Polish the faces to remove any lifting screw marks and traces of shocks.检查轴承表面及对正，磨光起吊痕迹?Change the parts deemed faulty:corroded,abraded,deformed,unbalanced or with abnormal assembly play.更换掉有缺陷的、磨损的、未平衡的及其他不适合装配的零件?Change seals,bearings at each disassembly and the stainless steel screws every three disassemblies.每次拆卸时更换密封件、轴承，每拆卸三次更换不锈钢螺栓。Notice N 813AN Print Date:June,04 Last Updated:Feb 2002 Page 4/29 1.3 Assembly of the ROTO joint in relative speed between screw and bowl?A ROTO joint is 5%longer than the groove which houses it.?The joint must therefore be compressed when fitted in its groove,which necessitates a certain level of experience on the part of the operator.?Oil the joint and the groove.?As shown in the drawing opposite,place the joint in the groove and leave two loops facing each other.Push the loops into the groove simultaneously and gradually,as shown by the arrows(F).?Touch the joint with a finger to ensure that there are no bulges remaining.If necessary,remove bulges by rubbing them gently with an oiled wooden handle.1.4 Assembly of bearings 装配轴承装配轴承?Clean and strip shafts and bores carefully.清洁轴与孔?If there is any doubt,check the shape and dimensions of the parts.若有疑问，检查部件尺寸?Leave bearings in their original packaging until they are required.未装轴承前不开包装?Do not hit bearings directly.勿直接击打轴承?The assembly stress must on no account be transmitted through the roller elements.?确保装配用力不通过轴承滚动体?Adjustment surfaces must be slightly oiled.调整表面可涂少许油?Bearings of smaller dimensions may be fitted with slight hammer blows applied using a mild steel circle or tube all around the ring to ensure the bearing fits properly.?小尺寸轴承可使用锤子或其他工具，确保轴承正确到位?Properly aligned stress is guaranteed when using a striking bush(Fig.1).使用装配套时要对正（图 1）?For simultaneous assembly of both rings,use an assembly similar to Fig.2?轴承内外环同时装配，使用类似图2 的工具 Notice N 813AN Print Date:June,04 Last Updated:Feb 2002 Page 5/29 1.5 Stainless steel fastenings 不锈钢紧固件不锈钢紧固件
