3807677 Self Aligning Bearing for Caterpillar

3807677 is a self-aligning spherical bearing used in Caterpillar track-type tractors. The part is identified for the equalizer bar assembly and is used in the BAR AS-EQUALIZER application on the specified Caterpillar D11 series machines.

This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The bearing is intended for use where the bearing element must accommodate alignment within the equalizer bar assembly. Its dimensions provide the identifying measurements for checking compatibility with the installed component and the corresponding bearing housing.

Fitment

• Caterpillar D11 track-type tractor
• Caterpillar D11R track-type tractor
• Caterpillar D11T track-type tractor

The listed fitment applies to the self-aligning bearing used in the BAR AS-EQUALIZER assembly. Before installation, the dimensions of the removed bearing and the receiving assembly should be checked against the specifications below.

Cross-reference numbers

3807677 and 380-7677 identify the same bearing reference in different number formats. The number is associated with the bearing used in the equalizer bar application for the Caterpillar D11, D11R, and D11T track-type tractor models.

Specifications

The inner diameter is 3.504 inches, and the outside diameter is 6.25 inches. The specified inner bearing length is 3.622 inches. These measurements describe the bearing itself and should be compared with the shaft, bore, and available width of the equalizer bar assembly during parts identification.

The self-aligning design is intended for the bearing position indicated by the BAR AS-EQUALIZER application. The part description, reference numbers, machine series, and dimensions should be considered together when confirming the required component for a Caterpillar D11, D11R, or D11T track-type tractor.
