PPE Transfer Case Pump Rub Kit. Cure the dreaded "Pump Rub" with PPE’s Transfer Case Pump Upgrade kit. Pump rub occurs when the 5 positioning tabs holding the pump in place wear over time, thus causing the oil pump to come into contact with the housing itself. The result is a hole in the cover, causing fluid to leak and the possibility of heavily damaging the transfer case. PPE’s kit consists of a new pump cover whose main feature is a more secure method of mounting the pump. All the necessary gaskets are included.For 261HD/263HD/261XHD/263XHD Transfer Cases

Merchant Automotive GM Transfer Case Pump Upgrade Kit (2001-2007)New
Here is the best upgrade you can make to your GM transfer case(model 136, 146, 246, 261, 261HD, 263HD, 263XHD, 261XHD). Prevent the ever increasing problem of pump rub. What is "pump rub" The GM transfer cases use a gear pump inside the case that is driven off the main shaft. The pump forces oil to the planetary as well as the drive sprocket sleeve. Because the pump is driven by the shaft, the housing of the pump must 'float' in the rear housing. There are 5 tabs around the housing that fit into spots in the rear housing to position the pump. Over time, the pump can start to wear on the rear housing. GM installed a spring steel clip in the housing intended to prevent wear but the clip can break and render useless Being that the pump housing is aluminum and is a harder material then the magnesium rear housing, it can wear a hole in the rear housing and cause a very small leak. This leak is high enough in the case that it typically will not leak when vehicle is not moving and therefor not leaving any drops on the ground. Typically the condition is not found until there is transfer case damage from running the case out of fluid. Avoid costly repairs to your transfer case by preventing this condition. Full installation instructions are available right here on this site. Look under the Tech Information link on the home page for step by step directions. With installation of this kit, you will have a LIMITED LIFETIME WARRANTY against pump rub. If your case ever wears a hole in the new rear housing with the upgrade installed. We will buy you a new transfer case. Included in the kit: Merchant Automotive billet transfer case pump housing Transfer case adapter gasket at trans RTV Silicone Blue Thread lock Merchant Automotive sticker If you already have a hole in your case, its recommended to install a new rear housing for a proper repair. Lifetime warranty will only apply to installations with a new rear housing.

Cracked transmission tail shaft housings (located between the transfer case and the transmission) are a common problem for GM Allison-equipped 4x4 pick-ups in off-road and drag racing situations. Even a normal amount of driveline vibration can cause the housing to fail, resulting in a transmission fluid leak or worse; internal transmission and transfer case damage. Once the housing cracks, repairing it requires removal of the transmission and transfer case.
