Description of Change: The housing of the metering pump group has been modified in order to allow adequate clearance for the wire to the horn. Previously, the wire could have become pinched. This could cause the horn to sound when the steering wheel is turned.

Adaptable To: The updated 222-3769 Metering Pump Gp has a modified housing in order to allow adequate clearance for the wire. Refer to Table 1 for the machine effectivity. The updated metering pump group is adaptable to all earlier motor graders.
