| B&M's new Task Master diesel converters are ideal for stock to modified diesel engines. They feature multiple disk lockup clutches, one-way clutch components, furnace brazed turbine and impeller and new turbine hub. These converters are intended to maximize the efficiency of the vehicle's engine and torque converter combination to improve acceleration and pulling power in light trucks. The Task Master series converters will add seat of the pants power to your diesel truck for towing or off-road applications! |

B&M Torque Converter Features
1. IMPELLER
Pumps fluid through converter and drives oil pump in transmission.
The impeller assembly is the a key area in the converter when considering the converters performance characteristics. The impeller can be modified to raise or lower the stall speed as well as affect the top end performance of the converter (MPH). By performing a fin bend change on the outside fins you can change the stall and change the top end MPH by a measurable amount.
2. FURNACE BRAZING
Furnace brazing (copper colored material visible on turbine fins) is a method used to strengthen converter components.
Braze material is applied to all of the fin areas, then the entire turbine is placed into a furnace, which heats up the braze material causing it to melt and fill the voids. Not only does this process strengthen the entire assembly it also makes the turbine more efficient by eliminating any of the cross leakage between the fins.
3. TURBINE
Spins input shaft in transmission.
The turbine assembly is completely furnace brazed. The turbine also includes a steel billet turbine hub with broached splines. This stronger turbine hub will eliminate the possibility of stripped splines in the center hub. The raised center section is designed to be a bearing and race pilot for the needle thrust bearing assembly.
4. STATOR
Multiplies torque by redirecting fluid flow in converter and incorporates one way clutch assembly
The stator has a very important function inside the converter as it multiplies torque by redirecting fluid flow in converter and it incorporates a one-way clutch assembly. The one-way clutch assembly allows the stator to hold, when the converter is multiplying torque and to spin in the direction of the oil flow when not holding.
5. COVER
Attaches converter to the flexplate
The cover assembly is essentially the stock cover with the addition of B & M designed drive lugs or modified stock drive lugs. The cover OD is machined to provide a smooth surface for the new body-weld. The pilot is inspected and re-machined as needed to provide a good fit into the crankshaft of the engine. This is extremely important as the pilot on the converter centers the converter behind the crankshaft. Proper alignment of the converter will eliminate most vibration problems related to the Converter and Transmission assembly.
