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.
