1) Description of Oil Purm Gear
Oil pump gears are powered by the crankshaft and in high horsepower or high revving applications the stock
oil pump gears can fail due to the increased harmonics, or oscillating of the gear from the added power and revolutions of the crankshaft.
There are two types of gear pumps – external gear pumps and internal gear pumps.
External gear pumps make use of two external opposing gears (typically spur gears) in transferring the fluid type.
Internal gear pumps use one outer ring gear and one internal pinion gear running inside the ring gear.
