SEAL-O-RING 1357935 - Caterpillar

The regular maintenance that is required for the oil mist detector is listed in Table 1. Make several copies of 1 in order to keep a record of the maintenance.The intervals for performing the maintenance are provided as guidelines. Particular installations may require more frequent maintenance intervals.
Table 1
Maintenance Schedule for the Oil Mist Detector    
Interval     Maintenance Procedure     Technician     Date    
When Required     Perform all of the following maintenance after the vessel has been in storage.            
Daily     Maintain the system for the compressed air.            
Every Month     Check the pressure of the vacuum in the measuring head. Adjust the pressure, if necessary. (1)            
Clean the box for the oil drain (if equipped).        
Every 3 Months     Perform the following maintenance on these items in the measuring head:
Clean the bores for the filtered air.
Replace the sintered bronze filters.
Clean the glass of the infrared filters.            
Every Year     Replace the sintered bronze filter for the pressure regulator.            
Clean the suction lines for sampling the atmosphere from the crankcase.        
Clean the oil drain line.        
( 1 ) When this procedure is performed after Every Three Months, perform this procedure last.Failure to perform the maintenance will have an adverse effect on the oil mist detector. Table 2 lists the conditions and the possible results of failure to perform the maintenance.
Table 2
Conditions and Possible Results of Failure to Perform Maintenance for the Oil Mist Detector    
Condition     Possible Result    
The air pressure from the air pressure regulator is too low.     Fault 14 is generated because the pressure of the vacuum in the measuring head is too low.    
The box for the oil drain (if equipped) is full.    
The line for the oil drain (if equipped) to the crankcase is clogged.    
The bores for the clean air in the measuring head are clogged.    
The sintered bronze filters in the measuring head are dirty.    
The filter for the pressure regulator is dirty.    
The glass of the infrared filters is dirty.     Fault 13 is generated because the infrared filter seems to be dirty.
Fault 3 is generated because the measuring track seems to be faulty.    
The sintered bronze filters in the measuring head are dirty.    
The air pressure from the air pressure regulator is too high.     The detector can fail to detect a condition of excessive oil mist.    
The detector can activate a false alarm for oil mist.
The sintered bronze filters become fouled quickly. A number 3 fault is generated.
The lines for sampling the atmosphere from the crankcase are dirty.     The detector can activate a false alarm for oil mist.    Most of the maintenance procedures can be performed with tools from the 132-8710 Tool Kit.
