Keeping the hydraulic system of a Caterpillar 308 excavator is critical for functional performance, component longevity, and safety and security. Hydraulic oil lubricates moving parts, transfers power, and dissipates warm. Contamination, destruction, or low oil degrees can cause early wear, lowered performance, overheating, and tragic system failure. Regular examination of hydraulic oil is a fundamental preventative maintenance job. This post information the procedure for examining hydraulic oil on a Feline 308 excavator.

Safety and security is extremely important. Park the excavator on level, steady ground. Involve the emergency brake. Lower the job devices (boom, arm, container) completely to the ground. Shut off the engine and get rid of the ignition key. Permit the hydraulic system to cool for at least thirty minutes; warm oil broadens dramatically and poses melt dangers. Put on ideal individual protective equipment, consisting of safety glasses and gloves.
Situate the hydraulic oil storage tank. On the Feline 308, it is generally positioned on the right-hand side of the machine’s top framework, behind a service door or accessibility panel. Identify the view scale or dipstick connected to the container cap. The sight scale is a transparent tube noted with level indicators (minimum and optimum lines). If outfitted with a dipstick, note that it may have two sets of markings: one for a chilly check (after shutdown) and one for a warm check (within 10 minutes of shutdown at operating temperature). Consult the Procedure & Maintenance Manual for the specific setup of your machine.
For a view scale check, visually examine the oil level against the significant lines. Make sure the oil degree is between the MIN and MAX indicators. For a dipstick check, remove the dipstick, wipe it tidy with a lint-free towel, reinsert it totally into television, wait a minute, then withdraw it once again. Read the oil level. If utilizing the cool markings, the degree needs to be within the designated cool array. If making use of cozy markings (applicable if examined within 10 minutes of closure), it must be within the cozy variety. Never ever contact a dipstick immediately after stopping a hot maker; wait for the oil to resolve.
At the same time examine oil condition. Observe the oil’s color and clearness through the view gauge or on the dipstick. New hydraulic oil is typically clear and light amber. Dimming suggests oxidation or contamination. Milky or foamy appearance recommends water ingress. Metallic bits or sludge signal internal wear or contamination. If contamination is suspected, further evaluation using oil tasting is advised. Keep in mind any uncommon smells, such as a burned scent.
If the level is listed below the MIN or cool LOW mark, enhancement is necessary. Usage just the hydraulic oil specified in the manual, typically Cat Hydraulic Oil or an equivalent meeting Pet cat TO-4 requirements. Sanitation is essential. Clean the filler cap and surrounding area thoroughly prior to removal to avoid dirt ingress. Make use of a clean funnel. Include oil incrementally, checking the degree frequently to prevent overfilling. Overfilling can cause frothing, overheating, and seal damages. Reconsider the degree after running the maker briefly to distribute the oil and after that shutting down once more.
If the oil degree is consistently low, investigate for leaks at hose pipes, installations, cylinders, or the container. Consistent contamination, considerable darkening, or the presence of water/metal demands an oil adjustment per the scheduled upkeep intervals or faster. Overlooking reduced levels or poor oil problem increases pump and shutoff wear, enhances operating temperatures, minimizes digging pressure and cycle times, and dangers pricey component failures like pump seizures or shutoff spool sticking.

Adherence to a stringent hydraulic oil examination program, done daily or prior to each shift according to operational intensity, ensures the Pet cat 308 excavator runs accurately and efficiently. Exact degree checks using the appropriate treatment and immediate corrective activity for deviations avoid functional downtime and pricey repairs. Constantly prioritize security and get in touch with the particular maker’s Operation & Upkeep Handbook for in-depth guidelines and specifications.
