| - | ====== Testing ====== | ||
| - | |||
| - | The reason for testing was due to the 07-up pump having a drain port (on top of the pump body) to drain the gearcase. \\ | ||
| - | 86-97 engines drain the gearcase into the crankcase sump area to be scavenged by the sump drain to the oil pump. \\ | ||
| - | 98-up engines drain the gearcase straight into the oil pump. \\ | ||
| - | However, the 07 pump is preferred as it has bigger scavenge gerotors that carry more oil out of the engine than it's predecessor. \\ | ||
| - | |||
| - | The pump was tested before and after the modification in Karlings oil pump test rig. \\ | ||
| - | |||
| - | During the flow test they used a reference volume filled from the scavenge outlet. \\ | ||
| - | The pump was driven at a controlled shaft speed and partially immersed in a low viscosity fluid to resemble the viscosity of hot engine oil. \\ | ||
