Caution before repair 1) Before repair or inspection 1. In case of repair or inspection, locate the tractor on the flat ground and pull the parking brake on. 2. Except for the items to be checked while the engine is running, be sure to stop the engine prior to the work. 3. When washing parts, apply parts detergent on sale for industrial use (avoid using gasoline so to prevent environmental pollution). For the hydraulic parts, apply designated functioning oil in washing. 4. When disassembling and assembling of the hydraulic apparatus, pay special attention not to allow dust or foreign substance to be attached or intermixed. 2) Assembly and disassembly To check an error, try to find out its underlying cause. If assembly or disassembly is needed, perform the work in regular sequence as specified in this repair manual. 1. Disassembled parts shall be arranged orderly. 2. Sort out the parts to be replaced from the ones to be recycled. 3. Be sure to use standard bolts and nuts designated. 4. When assembling snap rings or spring pin types, take care of assembling direction. 5. Split pin shall be spread surely not to escape when installed. 6. When using sealant (such as gasket bond) on the assembled surfaces, apply it evenly and incressantly in a height of 3-5mm on the contact surface after removing the old bond and cleaning the sealing surface with gasolinic wax. Apply sealant on the center of the contact surface for the space between the bolt holes of the contact surface, and on the more inner side than the bolt hole for the bolt area. 7. Finish assembly within 20 minutes after applying sealant, after that, wait approx. 30 minutes later before filling with oil.
