1.1. Location of the Lubrication Points
2.1. Recommended Lubricant

The automatic lubrication system is used to automatically lubricate the following components on the D11T Track-Type Tractor:

  • Lift cylinder yoke, left and right pivot bearings (two locations on each side)

  • Ripper tilt cylinder, left and right frame pivot bearings

  • Ripper lift cylinder, left and right frame pivot bearings

  • Ripper frame, left and right pivot bearings

  • Ripper lift cylinder, left and right pivot bearings

  • (Beam carriage), left and right pivot bearings

  • Ripper tilt cylinder, left and right pivot bearings

The automatic lubrication system consists of the following systems:

  • Electrically driven plunger pump with grease reservoir

  • Control unit (integrated in the pump housing)

  • Grease lines, distribution blocks, and metering units

  • In-cab display unit

The electrical drive pump is used to pressurize the lubrication system. The control unit turns the system ON and OFF at periodic intervals. The grease lines, distribution blocks, and metering units deliver a predetermined amount of grease to the grease points that is based on a fixed orifice in the metering unit. The heavy, normal, and light duty cycles pump grease every 20, 45, and 60 minutes. The in-cab display unit has a push-button that can be used to change the operating mode at any time. Pushing this button repeatedly will change the operating mode until the desired mode is selected.

Recommended Lubricant

Table 1 lists the recommended lubricant that is used for the automatic lubrication system.

Table 1
Recommended Lubrication for the Automated Lubrication System (1)    
Grease     NLGI     °C     °F    
AVSpare Autolube     1     -18     +29     0     +85    
AVSpare Autolube     2     -1     +41     +30     +105    
AVSpare Autolube     0     -29     +10     −20     +50    
AVSpare Arctic Platinum     000     -59     +4     −75     +40    
AVSpare Desert Gold     2     +4     +66     +40     +150    
( 1 ) In order to use a non-AVSpare lubricant, the supplier must certify that the lubricant is compatible with AVSpare's grease. Otherwise, each pin joint should be fully flushed with the new lubricant in order to entirely remove the AVSpare lubricant. Failure to meet this requirement may lead to failure of a pin joint due to premature breakdown of the lubricant.
