Feed oil grease. A Warning Notes: 1: Li quid packing (Three Bond TB1212) YANMAR part code : 977770 - 01212 2 : The data of tools described are width across flats. (2) Disassembly 1) Prepare the disassembly tools , measuring instruments and recording sheets. 2) Prepare the cleaning machines and cleaning vesse l. 3) Provide a space and containers for disassembled pa时s. 4) Drain the cooling water and lub. oil completely out of the engine. 5) Put the disassembled parts in order. 6) The material and dimensions of bolts and nuts differ from each other. To prevent use of wrong bolts or nuts , put them temporarily in their original position immediately after remova l. 7) If trouble is located , first determine the cause of the trouble to prevent removal or disassembly of pa同s unrelated to the trouble. (3) Assembly 1) Wash and check the parts to be assembled with due care. 2) Apply new engine oil or the specified lubricant to sliding parts and moving parts before assembly. 3) Replace gasket packings , copper packings and other packings with new ones. 4) Use liquid packing , if necessary, to prevent water and oilleakage. 5) Fit each part while checking oil clearance and thrust clearance. 6) Align all marked parts carefully during assembly. When fitting replacement pa同s， pay attention to their combination. 7) Do not confuse the bolts , nuts and washers , and tighten the major nuts and bolts to the specified torque. Take special care not to damage when tightening parts made of aluminum alloy. 8) Apply engine oil to the threads and bearing surfaces of major bolts and tighten them to the specified tightening torque. ^ NOTE Use a spanner wrench during disassembly and a torque wrench during assembly.
