(4) Tapped holes on the equalizer bar are for bolting the lubrication lines in place (5) Location of the port for the lubrication lineThere are three different kinds of equalizer bars used on D9R and D9T Track-Type Tractors. Refer to Illustrations 1 and 2 to determine which type of equalizer bar is on the machine.The first type of equalizer bar, Type 1, has no Center Lubrication Groove (1), Identification Mark (3), Tapped Holes (4), or Lubrication Line Port (5). The second type of equalizer bar, Type 2, does not have a Center Lubrication Groove (1) or Identification Mark (3). However, Type 2 does have Tapped Holes (4), and a Lubrication Line Port (5) .The third type of equalizer bar, Type 3, has a Center Lubrication Groove (1), Identification Mark (3), Tapped Holes (4), and Lubrication Line Port (5).
