The ring gear is bolted to the differential and the pinion gear is inside this assembly with its shaft exiting the housing to mate with the driveshaft yoke. Always replace a ring-and-pinion as a set; they are manufactured and lapped to each other as a matching set.
Those pictures were taken over the course of a few days. You can pretty much watch this happen. But now it will take another two months or so, depending on the temperature, for the fruit to fill out and finally ripen. A banana plant takes about 9 months to grow up and produce a bunch of bananas. Then the mother plant dies. But around the base of it are many suckers, little baby plants. At the base of a banana plant, under the ground, is a big rhizome, called the corm. The corm has growing points and they turn into new suckers.
How Long a Banana Pseudostem Lives. A banana pseudostem needs 10 to 15 months of frost-free weather to grow flowers that yield young bananas. The bananas typically mature in 60 to 90 days after the flowers appear. The exact lifespan of a banana pseudostem depends on the species of banana and the weather. Most banana varieties stop growing when the temperature drops below 53 degrees Fahrenheit. Their growth slows at 80 degrees Fahrenheit and stops completely at 100 degrees Fahrenheit.
