Lubrication specifications
Lubricate only when parts are replaced or as needed, not on a scheduled basis. Use of lubricants other than
those specified can cause premature failure. Some unauthorized lubricants may chemically attack
polycarbonate parts. Use IBM no. 10 oil, P/N 1280443 (Approved equivalents: Mobil DTE27, Shell Tellus 100,
Fuchs Renolin MR30), IBM no. 23 grease (Approved equivalent Shell Darina 1), and grease, P/N 99A0394 to
lubricate appropriate areas. Use Nyogel type 774 to lubricate the Fuser Drive Assembly and Nyogel 744 to
lubricate the ITU and Cartridge Drive assemblies.
Lubrication for replacement motors
The motor drive FRUs contain the proper lubricant in the FRU. Only use the lubricant included.
Fuser drive assembly
Before installing the new fuser drive assembly:
1. Apply a thin coating of Nyogel type 774 grease to the points identified (A) from the supplied packet.
2. Rotate the motor housing (B) to distribute evenly.
