SUPPORT-AIR CLEANER 8N3214 - Caterpillar

Inspect the Engine for Leaks and for Loose Connections
A walk-around inspection should only take a few minutes. When the time is taken to perform these checks, costly repairs and accidents can be avoided.For maximum engine service life, thoroughly inspect the engine compartment before starting the engine. Look for items such as leaks, loose bolts, loose connections, and trash buildup. Make repairs, as needed.
The guards must be in the proper place. Repair damaged guards or replace missing guards.
Wipe all caps and plugs before the engine is serviced to reduce the chance of system contamination.
For any type of leak (coolant, lube, or fuel) clean up the fluid. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more often than recommended until the leak is found or fixed, or until the suspicion of a leak is proved to be unwarranted.
Accumulated grease and/or oil on an engine or deck is a fire hazard. Remove this debris with steam cleaning or high pressure water.
Note: Use care when you use steam cleaning. Use care when you use high-pressure water. Direct spray to rotating electrics or electronic components can cause nonfixable damage.
Water and/or condensation can cause damage to electrical components. Protect all electrical components from exposure to water.
Ensure that the cooling lines are clamped properly and ensure that the cooling lines are tight. Check for leaks. Check the condition of all pipes.
Inspect the water pumps for coolant leaks.Note: The water pump seal is lubricated by coolant in the cooling system. When the engine cools and the parts contract, a small amount of leakage is normal.Excessive coolant leakage may indicate the need to replace the water pump seal. For the removal of water pumps and the installation of water pumps and/or seals, refer to the Disassembly and Assembly Manual, "Water Pump - Remove and Water Pump - Install" or consult your Cat dealer.
Inspect the lubrication system for leaks at the following locations: front crankshaft seal, rear crankshaft seal, oil pan, oil filters, valve cover, turbocharger, external oil lines, and connections.
Inspect the fuel system for leaks. Look for loose fuel line clamps or connections.
Inspect the piping for the air inlet system and the elbows for cracks and for loose clamps.
Drain the water and the sediment from fuel tanks daily to ensure that only clean fuel enters the fuel system.
Inspect the wiring and the wiring harnesses for loose connections and for worn wires or frayed wires.
Inspect the ground strap for a good connection and for good condition.
Inspect the closed crankcase ventilation (CCV) filter, if equipped. If the restriction indicator is visible, service the CCV.
Check the condition of the gauges. Replace any gauge that is damaged. Replace any gauge that cannot be calibrated.
Inspect the exhaust system for leaks. Inspect the gaskets and the exhaust bellows joint. If a leak is found, make repairs.
Ensure that sensors are not covered with insulation. The insulation would trap heat in the sensor body and cable. This heat may cause sensor failure.
