GRN4-600 Chapter 5: Maintenance 29 of 50
NOTE: Unsuitable lubricant, lubricant deficiency, excessive lubricant, or impurities
in the lubricant lead to overheating and extreme wear of the bearings.
Lubrication intervals
Use the following table to determine when to check and replace the lubricant.
Shift Operation When to Replace When to Check
One shift operation. Every 18 months. Monthly.
Two shift operation. Every 9 months. Monthly.
Three shift operation. Every 6 months. Monthly.
Checking lubricant quality
When determining whether a lubricant needs to be replaced, check for the following:
• Change in consistency.
• Discoloration.
• Degree of soiling.
Replacing or refilling lubricant
• Fill the bearings uniformly with grease until all operating surfaces are well
greased.
• A lubricant quantity of 1/3 to 1/2 of the bearing volume per bearing is
required. If too much grease is used, the lubricant will become unusable due
to excessive temperature.
• Only one type of grease must be used. Mixing different types of grease
together is prohibited. The bearings are filled at the factory with lithium
base saponification roller bearing grease F3.
• Use the “List of lubricants” to determine which lubricants from which
manufacturers to use.
Refilling lubricant
The grease travels through the circulating grooves and bores via lubrication nipples into
the interior of the bearing. The greasing quantity is 2 oz. (60g) to 3.5 oz. (100g) roller
bearing grease F3 per bearing.
