6V4163 Bit And 6V4164 Driver Now Available For Removal Of Bolts For Flyweight Carrier{0612,1264}
Usage:
All Engines With Sleeve Metering Fuel System
An 8N2663 Carrier is now used instead of the former 4N446 Carrier in sleeve metering fuel systems. New bolts are used to hold the 8N2663 Carrier in place. The new bolts have a smaller internal hex than the former bolts.
The 6V4163 Bit and 6V4164 Driver are now available for removal of these bolts with the smaller internal hex.
The new driver and bit can be used with a higher torque than the 2P8263 Socket Assembly. This extra torque is necessary for removal and installation of the carrier bolts.
