When compared to competitive axles that continuously operate a lube pump, this efficiency upgrade saves up to 2HP and also decreases oil sump temperature by as much as 20°F. The wasted HP incurred by the other axles relates directly to reduced fuel economy, higher temperatures in the lube sump, and reduced lubricant life.

Dana has engineered in a significant product upgrade to the current 40K tandem axles. At the core of these product enhancements is the incorporation of Dana’s patented and proven On Demand™ lube pump. This innovative lubrication system operates primarily during spinout situations. The remaining 99+% of the time, the pump is idle and ready to be activated instantaneously, in forward or reverse. When compared to competitive axles that continuously operate a lube pump, this efficiency upgrade saves up to 2HP and also decreases oil sump temperature by as much as 20°F. The wasted HP incurred by the other axles relates directly to reduced fuel economy, higher temperatures in the lube sump, and reduced lubricant life. The new design carriers have been optimally designed such that there is now a 12lbs weight savings on pump carrier models. This same system is currently used in the D170 and D190 family of heavy duty tandems.
SERVICE PARTS IMPACT: Use of the new design units in Australian Locally built axle assembly’s begins February 2010.These design upgrades will impact customers who stock parts or service carriers for the models listed above. Service Carriers are completely interchangeable as units. Individual internal parts and kits are not interchangeable! It is important for customers to beware of the part number changes and in time begin making stocking adjustments accordingly

NEW SERVICE PART NUMBERS: Outlined below are the newly released service parts. Dealers should begin to maintain an initial level of these parts going forward as the individual parts between the old and new are not compatible. All parts for the older design carriers will continue to be offered thru service. BASIC OVERHAUL KITS – Dana has reduced the complexity of the repaired kits offered on the new carriers by only releasing Basic Overhaul Kits. Two new kits have been released that come complete with all the necessary bearings, shims, washers and RTV sealant required when doing an overhaul. NEW OVERHAUL KIT PART NUMBERS: 504030 – Basic Overhaul Kit – D40K Standard Models [Models: DS344, DS404, DS405, DSP40, DSP41, DST40, DST41, DSH40, DSH44] 504031 – Basic Overhaul Kit – D40K Diff-Lock Models [Models: DD404, DDP40, DDP41, DDH40, DDH44] INPUT SHAFT KITS – The new design carriers now utilize a “Pump” version and a “Non Pump” version input shaft. The part number of the shaft is stamped on the part for easy identification. Each shaft is sold thru service in a kit form that includes the nut, thrust washer and torque information sheet. NEW INPUT SHAFT KIT PART NUMBERS: 504026 – Input Shaft Kit - Non Pump (shaft p/n 132447) 504027 – Input Shaft Kit - Pump Models (shaft p/n 132446) LUBE PUMP, OUTPUT SHAFT SIDE GEARS AND LOOSE PARTS – Listed below are the balance of the new individual service parts located in the power divider section of the forward carrier. These parts are related directly to the new design lube pump system. Detailed parts and illustrations are shown on pages 4 & 5 of this bulletin. IMPORTANT NOTE: The output shaft side gears are designed for use with specific input shafts, i.e. pump design vs. non pump design. Do not to mix these parts. Use pump model output shafts with pump model input shafts as well as non-pump output shaft side gear with non-pump input shafts! Mixed parts will assemble together, but they are not designed to run together and failure will occur if any parts are mixed.
