(A) A-Pin (B) B-Pin (C) C-Pin (E) E-Pin (F) F-Pin (G) G-Pin (H) Pin for Upper Articulation Joint (J) Pin for Lower Articulation Joint (K) K-Pin (L) Steering Cylinder Pins (X) Trunnions (Y) Y-PinThe controller of the autolube system is preset from the factory and shipped from the factory so that lubrication is dispensed at 15 minute intervals, and all of the injectors are preset at the full flow setting. This can cause an excessive buildup of grease around some of the joints. As a result, the grease reservoir may need to be filled more frequently. The injectors for selected joints can be adjusted in order to reduce the flow of grease without adversely affecting the life of the pin. The injectors are set by the factory at the full flow setting. This setting is equivalent to 8 turns open. When the injectors are adjusted, the injectors should first be closed. Then, the injectors should be opened by the number of specified turns. The recommended settings for the injectors at each pin location are listed in Table 1.
Table 1
Pins     Qty (Injectors)     Settings (Turns)    
A     2     8    
B     2    
C     2    
E     3     5    
F     2     2    
G     1     8    
H     1     2    
J     1    
K     2     8    
L     4     2    
X     2     8    
Y     2     8    Note: By using the above settings, the buildup of grease will be reduced and the interval between refills of the reservoir will be extended to approximately 250 hours. Grease levels in the reservoir must be checked in order to ensure an uninterrupted flow.
