LUBRICATION.
Universal joints requiring a grease lubricant should be lubricated with any good grade of "O" chassis lubricant.
Grades 1 and 2 may be required for use in hot weather and heavy duty service. good grade of 140 mineral oil is also
approved. The lubricant should be a high N melting point fine fibre grease.
The interval between lubrications depends on the types of service. An interval of 400 hours between lubrications is
generally satisfactory for normal service. A 100 hour interval is recommended for heavy duty service.
When subjected to extremely severe conditions, more frequent lubrication may be required.
Lubrication must be done with a low pressure hand type grease gun or a high pressure gun with a low pressure adapter
only. High pressure will rupture the cork seals.
