Component Code(s) 1326SUBJECT: ENGINE OIL LEVEL GAUGE MAY BE INCORRECTLY MARKED ON CERTAIN 966G II AND 972G II WHEEL LOADERS
PROBLEM:
The engine oil level gauge may be incorrectly marked on certain 966G II and 972G II Wheel Loaders. This may result in under-filling the engine crankcase by approximately 3 liters relative to the correct refill level of 35 liters.
SOLUTION:
A new oil level gauge will be available soon to replace the 228-5226 and 233-6201 Oil Level Gauge Group (Dipstick). Until the replacement gauge is available, the following procedure may be applied.
Check the calibration of the oil level dipstick at oil and filter change period using the following procedure:
Insure that the machine is on a level surface. Operate the engine until normal operating temperature is achieved. Stop the engine. Remove the crankcase oil drain plugs. The oil drain plug from the deep portion of the oil pan should be removed. The oil drain plug from the shallow portion of the oil pan should be removed. This will allow all of the oil to drain. Drain the oil from the crankcase for 20 minutes.
Remove the used oil filter(s). Install the new oil filter(s). Install the oil drain plugs and tighten to 70 ? 15 N?m (50 ? 11 lb ft).
Note: Your engine may be equipped with auxiliary oil filters. The auxiliary oil filters require a different volume of oil. Refer to the OEM specifications for the auxiliary oil filter.
Pour 27 L (28.5 qt) of oil into the crankcase. Allow enough time for the oil to drain into the crankcase. Approximately 20 minutes should be allowed. Check the oil level. Wait for several minutes and check the oil level again. Proceed after the oil level stops changing.
Check the oil level on the oil level gauge. The oil level should be at the "ADD" mark. If the oil level
