Test data Ex:
0000001801 TIMER STROKE
Timer adjustment
Assemble the timer's measuring device on the low pressure side and measure timer advance.
Select one of the 6 timer springs. It is necessary to install at least 1 shim (0.6 mm) on either side.
Maximum is L1 mm on piston side and L2 mm on cover side. Do not exceed.
Use pipe corresponding to 146606-3920.

Adjustment of the V-FICD
1. Adjust the actuator rod to obtain S1.
2. Apply negative pressure P1 to the actuator and confirm the full stroke.

Information:
Do not use single grade API CF oils or multigrade API CF oils in Cat 3500 Series, C175 Series, and smaller Direct Injection (DI) diesel engines.API CF oils are only recommended for Cat 3600 Series and C280 Series diesel engines, and Cat engines that have precombustion chamber (PC) fuel systems. Oils that are used in Cat 3600 Series and C280 Series diesel engines must also pass a 7000 hour field performance evaluation. Contact your Cat dealer for details.
Fuel Sulfur Impact on Engine Oil
Follow the recommendations given in the "Fuel Sulfur Impact on Engine Oil" section given earlier in this Special Publication in the Engine Oil chapter.Use the oils recommended for the precombustion chamber engines in order to ensure the protection of the engines and follow the recommendations in your Operation and Maintenance Manual for oil drain intervals.
Depending on application severity and localized environmental conditions, and also depending on maintenance practices, operating Direct Injection (DI) diesel engines and operating PC (Precombustion Chamber) diesel engines on fuel with sulfur levels over 0.1 percent (1000 ppm) may require shortened oil change intervals to help maintain adequate wear protection. Refer to this Special Publication, “Fuel Specifications” section, “Diesel Fuel Sulfur” topic for additional information.
Note: For PC (Precombustion Chamber) diesel engines, which are mainly 1990 and older engines, the minimum new oil TBN must be 20 times the fuel sulfur level. The diesel engine oil types, specifications, and viscosity grades recommendations provided for DI diesel engines in this Special Publication are also applicable to PC diesel engines.Consult with your Cat dealer regarding the testing that is required in establishing oil drain intervals that are optimized for your application.
