LINK 7S9110 - Caterpillar

The combination blowby/air flow meter.Also, make the following corrections to the Special Instruction:
Several early indicators were shipped with only temporary instructions in the box. Scrap the temporary instructions and replace them with the referenced form SEHS8712.... On Page 2, in the list of repair parts for Item (7), change "8T0899" to "8T0999".... On Page 11, in the second paragraph, change the word "one" to the word "two". In the same paragraph, change the number "1" after the equal sign to "2". This doubles the MAXIMUM allowable blowby rate for a new engine.... Also on Page 11, make two changes in the table under the heading "Blowby Range" for both types of the 3204 Engines. The recommended range for ALL 3204 Engines is now 52 to 104 L/Min (110 to 220 cu ft/hr).
