Lubricating Oil Level; Drive Belts - Doosan DX140R Shop Manual

Lubricating Oil Level

Maintenance Check
Never operate the engine with oil level below the L (low)
mark or above the H (high) mark. Poor engine performance
or engine damage can occur.
The engine must be level when checking the oil level to make
sure the measurement is correct.
Shut off the engine for an accurate reading.
Wait at least 15 minutes after shutting off the engine to check
the oil level. This allows time for the oil to drain into the oil pan.
For additional lubricating oil recommendations and oil pan
capacity information, refer to "Maintenance Specifications" on
page-245.

Drive Belts

Maintenance Check
Poly-Vee Belt
Inspect the belts daily. Check the belt for intersecting cracks.
Traverse (across the belt width) cracks are acceptable.
Longitudinal (direction of belt length) cracks that intersect with
transverse cracks are not acceptable. Replace the belt if it is
frayed or has pieces of material missing. Refer to Section A for
belt adjustment and replacement procedures.
Belt damage can be caused by:
• Incorrect tension
• Incorrect size or length
• Pulley misalignment
• Incorrect installation
• Severe operating environment
• Oil or grease on the side of belts.
