5068-507

Inspect a Used Filter for Debris

g00100013

Illustration 210

The element is shown with debris.

Use a 4C-5084 Filter Cutter or a 175-7546 Oil

Filter Cutter to cut the filter element open. Spread

apart the pleats and inspect the element for metal

and for other debris. An excessive amount of debris

in the filter element can indicate a possible failure.

If metals are found in the filter element, a magnet

can be used to differentiate between ferrous metals

and nonferrous metals.

Ferrous metals can indicate wear on steel parts and

on cast iron parts.

Nonferrous metals can indicate wear on the

aluminum parts of the engine such as main

bearings, rod bearings, or turbocharger bearings.

Small amounts of debris may be found in the filter

element. This could be caused by friction and by

normal wear. Consult your Caterpillar dealer in

order to arrange for further analysis if an excessive

amount of debris is found.

Using an oil filter element that is not recommended

by Caterpillar can result in severe engine damage

to engine bearings, to the crankshaft, and to other

parts. This can result in larger particles in unfiltered

oil. The particles could enter the lubricating system

and the particles could cause damage.

Radiator Core - Clean

SMCS Code: 1353-070-KO

Open the rear grill in order to access the radiator.

g00100062

Illustration 211

You can use compressed air, high pressure water, or

steam in order to remove dust and other debris from

the radiator core. However, the use of compressed

air is preferred.

Reference: Refer to Special Publication, SEBU0518,

“Know Your Cooling System” for the complete

procedure for cleaning the radiator core.

Ride Control Accumulator -

Check

SMCS Code: 5077-535-R6

Note: When the ride control accumulator is properly

charged, the fore and aft motion of the machine is

reduced by the ride control accumulator.

Special tools and equipment are required in order

to test the accumulator.

Reference: For more information, refer to Testing

and Adjusting, SENR4932, “950f Wheel Loader and

950F Series II Wheel Loader Hydraulic System”,

“Accumulator (Ride Control) - Test and Charge” or

consult your Caterpillar dealer.
