117-4015 Straight Sleeve Bearing for D9T, D9R and D9 GC Track-Type Tractor
The D9 series operates under load conditions that most machines never see — sustained push work, deep ripping in abrasive ground, and continuous hours that accumulate fast on undercarriage components. When a sleeve bearing in this platform needs replacing, dimensional accuracy and material consistency matter more than they do on lighter equipment. This P/M steel straight sleeve bearing is cross-referenced to Cat part 117-4015 and manufactured to match the original bore tolerances for D9T, D9R and D9 GC machines. It is the kind of component that rebuild shops source specifically because the D9 sees high rebuild frequency — and getting the bearing wrong means pulling the machine again far sooner than it should.
What Sets This Bearing Apart for D9 Applications
Compared to the D7 or D8 series, the D9 platform carries significantly more machine weight through its pivot and support positions. A bearing that passes a dimensional check but lacks adequate material density will show accelerated bore wear — typically within the first few hundred operating hours after a rebuild. Sintered powdered metal construction handles this by distributing contact stress more evenly across the bore surface and releasing retained lubricant gradually as the bearing heats up under load.
This bearing carries no grease hole and no cross holes, which removes one potential failure point from the assembly. If your position requires a lubrication port, this part is not the correct match — measure your old bearing and confirm the specification before ordering. For shops sourcing bulldozer parts for D9 rebuilds at volume, confirming the part number against measured dimensions is standard practice before committing to a batch order.
