General Information
- Cleaning Clean the metal parts with cleaning solution that meets the standard and steam cleaning. (except for bearings) After cleaning, dry well, and inject oil in all parts. Also inject oil into the bearings after drying. Inspection When disassembling parts, check all the parts. If there are any worn or damaged parts, replace them. Inspect carefully to prevent initial breakdowns.
- Bearing Replace any loose bearings. Air dry bearings before installing them. Needle bearing When inserting needle bearings, be very careful not to damage them. Apply grease to the section where the needle bearing will be inserted. Gear Check that there is no wear and no damage. Oil seal, O-ring, gasket Always install new oil seals, O-rings, and gaskets. Apply grease to sections where oil seals and O-rings will be inserted. Shaft Check that there is no wear and no damage. Check the bearings and check for damaged oil seals on the shaft.
- Service parts Install LBX Link-Belt genuine service parts. When placing an order, check the parts catalog. It contains the LBX Link-Belt genuine part numbers. Any breakdowns arising from the installation of non-genuine parts are not covered by the warranty. Lubricants (fuel, hydraulic oil) Use the oil from the specified company or specified in the operator’s manual or service manual. Any breakdowns arising from any fuel or hydraulic oil other than those specified are not covered by the warranty.
