All Engines Equipped With New Scroll Fuel SystemSUPPLEMENT: 11/07/83SERVICE MAGAZINE, OCTOBER 3, 1983, PAGE 5.Put a mark through the article "Use 6V6070 Tool Group And ..." and make reference to a new article with the same title in this publication. The new article has some changes in the chart.--------------- END SUPPLEMENT ---------------The new 6V6070 Governor Adjusting Tool Group has the tools that are needed to check and adjust the rack and the fuel ratio control linkage on all engines with New Scroll Fuel Systems (NSFS). This new tool group is a replacement for the former 6V4095 and 6V4096 Groups which are canceled. All of the tools in the former groups except for the 6V2128 Compressor are still available for parts service. The 6V2128 Compressor is canceled. The former 6V4096 Group had tools to check and adjust the governors on 3204, 3304 and 3306 Engines. The former 6V4095 Group had all the tools that were in the 6V4096 Group plus the special tools which were needed to disassemble and assemble the fuel pumps and governors on 3204, 3304 and 3306 Engines.
Two of the new tools in the 6V6070 Group are the 6V7941 Overfueling Spring Compressor and 6V7942 Hook. The compressor is a replacement for the former 6V2128 Compressor. The new 6V7941 Compressor has enough movement so it can be used on 3204, 3304, 3306, and 3406 Engines with NSFS. The former 6V2128 Compressor did not.
The 6V7942 Hook is used to pull the rack against the rack centering pin on engines with negative rack settings. This is because on some of these engines the overfueling spring may not move the rack against the centering pin.
A new procedure is now used to check and adjust the rack on these engines. Special Instruction, Form SEHS8024, has complete information for the use of the new tools.
The components of the new 6V6070 Tool Group are shown in the chart that follows.
