General Information:
Cleaning
Clean the metal parts with a cleaning fluid or steamer that meets standards. (except for the bearing) After cleaning the parts, let them dry well and inject oil into all parts. Inject oil into the bearing after letting it dry.
Inspection
When disassembling parts, inspect all the parts. Replace any worn or damaged parts. Inspect them thoroughly to prevent early failures.
Bearing
If the bearing is loose, replace it. Install the bearing after air drying it.
Needle bearing
When inserting the needle bearing, be careful not to scratch it.
Inject grease into the location where the needle bearing is to be inserted.
Oil seals, O-rings, gaskets
Always install new oil seals, O-rings, and gaskets. Inject grease into the locations where oil seals and O-rings are to be inserted.
Shaft
Check for any wear or damage. Check the oil seal on the bearing and damaged shaft.
Service parts
Install genuine LBX Link-Belt service parts. When ordering parts, see the parts catalog that has genuine LBX Link-Belt part numbers listed. Any failures caused by installing a nongenuine part are not covered by the warranty.
Lubrication (fuel, hydraulic oil)

• Use oils from specified manufacturers or the ones specified in the operator’s manual or Service Manual.
• Any failures caused by using other fuel or hydraulic oil than specified are not covered by the warranty.
