ENGINE MAINTENANCE - Maintenance Procedures Exhaust System General information on maintaining the exhaust system. Batteries, Cables, and Connections Maintenance checks for electrical components. Engine Mounting Bolts Maintenance guidelines for engine mounting bolts. 2 The exhaust system is part of the noise and emission control system. Periodically check the exhaust system for wear, exhaust leaks, and loose or missing parts. For details on how to maintain the emisssions components in the exhaust system, see "Noise and Emission Control" in your vehicle operator's manual.
Please refer to the Engine Operator's Manual for more details on how to maintain the emission's components in the exhaust system. Perform these maintenance procedures according to the Preventative Maintenance Schedule. 1. Check the following electrical components: Perform these maintenance procedures according to the Preventative Maintenance Schedule. Check for the following: 1. Inspect both mount and leg fasteners. Check for loose or broken bolts. Replace as necessary. 2. Check mount and leg for fractures, breaks or deformation. Replace as necessary. 3. Check for complete insertion of motor mount. Replace as necessary. Condition – electrolyte level, cracks, signs of leaking, overcharging.
Hold–downs – tightness. Battery box mounting bolt – torque. Crankshaft - Vibration Damper Maintenance checks for the engine crankshaft. Charging - Cranking System Electrical Harness / Cables Maintenance checks for the electrical harnesses and cables. CAUTION Perform these maintenance procedures according to the Preventative Maintenance Schedule. 1. If equipped with a rubber type crankshaft damper, perform the following checks of vibration damper. Perform these maintenance procedures according to the Preventative Maintenance Schedule. 1. Check the following electrical components: Do not re-torque or reuse existing flange head bolts. These bolts are fac- tory set to the specified torque.
If bolts are loose or damaged, they must be replaced with the new bolts. Failure to comply may result in equipment or property damage. Inspect for loose connections, corrosion, chafing, and broken retention clips. Inspect for cracks, nicks, leakage. Check fastener torque. 78 Y53-1166-1G1 (08/2018)
