5540F/YB5515 SERVICE MANUAL PREVENTATIVE MAINTENANCE
Replace the Crankcase Oil and Filter
Change the engine oil more frequently if operating under
difficult conditions, for example in high or low temperatures,
dusty surroundings or frequent starting and stopping.
NOTE: If it is necessary to climb under the crane to change
the engine oil and replace the engine oil filter, be
sure engine is shut off, the ignition key is removed
and chock blocks are in place before climbing
under the crane.
NOTE: Drain the engine oil only when it is hot and the
contaminants are in suspension.
NOTE: Hot oils can cause personal injury.
1. Operate the engine until the water temperature reaches
140° F (60° C).
2. Shut off the engine
3. Place a suitable container under the engine drain plug.
Remove the oil drain plug.
4. Clean the area around the engine oil filter head.
5. Remove the filter and clean the gasket surface of the
filter head.
NOTE: The O-ring can stick on the filter head. Make sure it
is removed before installing the new filter.
6. Fill the new filter with clean recommended lubricating oil
(See engine operator’s manual furnished with the
crane).
7. Apply a small amount of clean engine oil to the gasket of
the new oil filter. Turn the filter clockwise to tighten it until
the gasket makes contact. Then, tighten the filter 1/2 to
3/4 turn to get correct seal.
8. Fill the engine crankcase with clean recommended
lubricating oil.
9. Operate the engine at idle and inspect for leaks at the
filter and drain plug
Torque Critical Bolts
NOTE: Maintain correct torque on all bolts. Failure to do so
may result in severe damage to the machine.
Hoist Winch Gearbox Mounting Bolts
Torque the 3/4” mounting bolts (4) to 280 lb-ft (380 Nm). See
Figure 5-29.
Swing Gearbox Mounting Bolts
Torque the 3/4” gearbox mounting bolts (4) to 200 lb-ft
(272 Nm). See Figure 5-30. If the bolts are loose, check gear
backlash.
Mast Mounting Bolts
Because of the cyclic loading on the mast bolts, it is
important that these bolts be checked at regular intervals.
Make a record of any loose bolts. If any bolt does not hold to
correct torque after the second check, remove and replace
the bolt. A loose bolt indicates possible failure of the bolt.
The correct torque on each outside bolt (mast to swing
bearing) should be 158 lb-ft (215 Nm). The correct torque on
each inside bolt (swing bearing to frame) should be 282 lb-ft
(381 Nm).
Use the torque sequence shown in Figure 11-124 when
checking the torque on the bolts.
NOTE: Use only special Grade 8 for replacement of the
mast bolts. Order the bolts from your dealer, see
your parts manual.
