Introduction
This technical bulletin pertains to balancing the lubrication to the pin joints on the 994F Wheel Loader.Problem
There is a lack of lubrication to the A-pin.Solution
Increase the amount of grease to the A-pin by decreasing the interval of the lube cycle from 15 minutes (factory setting) to 8 minutes. Decrease the cycle time to 8 minutes by using the VIMS keypad.Adjust the injectors at all other pin joints in order to reduce the grease flow. This will prevent having excess grease at the other pin joints.See the table for each injector setting.
