DIESEL LUBE OIL COOLING AND PURIFICATION SYSTEM DRAWING FS 430 The normal operating pressure on the lubricating system is 20-30 psi as read on G-l or G-2, and the normal operating temperature should be 190°F as read on T-1. The strainer is normally cleaned by turning the handles located on the top side of the strainer. These handles should be turned three or four times a day; check the lubricating oil at the filter gauge. When the oil pressure reaches 30 or 40 pounds or when the oil flow is insufficient to keep the oil in desired condition, the filter cartridges should be replaced. However, once a week the strainer cartridge should be removed and cleaned. Remove drain plugs and allow lube oil remaining in strainer case to drain in bucket. Clean strainer, cartridge and case. Replace drain plugs and cartridge. An oil level gauge dip stick is provided at the control side of the engine for measuring the oil level. The lubricating oil in the system should be completely drained and renewed at regular intervals; the time period between oil changes depends upon engine operating conditions and the type of lubricating oil used. For additional care and cleaning of lube oil system refer to Manufacturer's Instructions. 3-5
