Oil pump driven gear FORD HF35 Hybrid
The displacement of the center of the shaft axis due to the broken seat in the aluminum plate entails a displacement of the teeth relative to the teeth of the oil pump drive drive gear, which is drawn on the rear of the planetary gear and forms a single whole with it. As a result, the teeth overlap each other, which leads to their damage and the formation of a large gap between the teeth; this leads to incorrect operation of the oil pump, disruption of oil circulation in the transmission - the transmission begins to overheat, and scuffing appears on the gears of the oil pump.
Over time, the engagement between the drive and driven gears of the oil pump drive disappears, the gears slip, which leads to the complete destruction of the driven gear and damage to the drive gear, which is located on the rear of the planetary gear. The oil pump drive is damaged and the oil pump does not function. Oil circulation is stopped, metal-on-metal friction begins, the transmission overheats, further movement is impossible, the final result is a major overhaul of the transmission.
The most common problem associated with the oil pump driven gear is a design miscalculation or a specially calculated design limitation of the transmission life, but opinions can be purely subjective.
Let's look at the problem in more detail. The shaft with the driven gear of the oil pump has two points of support: the first is the aluminum housing of the oil pump itself, into which the shaft fits and connects to the drive gear of the oil pump. The second support point falls on the aluminum support plate, on which the seat of the support ball radial bearing of the rotor shaft of the transmission electric motor-generator is located. The emphasis is on the aluminum material from which the oil pump housing is made. And the support plate was not made by chance, since the driven gear itself with the shaft is made of steel, which has a metal density many times greater than aluminum. It is worth noting that the steel gear shaft works directly on aluminum; the gear shaft workplaces do not have sliding bushings. During long-term operation, the shaft breaks the seat in the support plate and loses alignment relative to its original position.
