When the bearing shield is opened and LS bell hammer is applied, an appropriate amount of lubricating grease is filled, but it is better to take out the lubricating grease (degreasing) and apply bell hammer gold to refill the grease. ?

If you take out the lubricating grease (degreasing) and apply the LS bell hammer, you can expect a longer life than applying it without removing the grease.
If the enclosed oil is oil, we recommend spraying or stock solution, and if it is grease, LS bell hammer grease #2 is recommended.
