What does a pinion gear do?
What does a pinion gear do?
gears. …of a gear pair (the pinion) is on the driving shaft, the pair acts to reduce speed and to amplify torque; if the pinion is on the driven shaft the pair acts as a speed increaser and a torque reducer.
Where does the input pinion gear go on a split axle?
An input pinion gear (flat-end cone-shaped) is turned by the pinion shaft at the end of the drive shaft. It meshes with a bevel or ring gear. It is an open-bottomed pie-plate looking gear with the left or right axle going through the open bottom. The differential end of each split axle is a bevel or side gear, also known as a sun gear.
Where are the teeth on a pinion gear?
Examine the teeth on the pinion gear as they fit into the larger ring gear. Normal patterns of wear for both these gears is perfectly down the center of the gear teeth. If you see wear near the edges or on alternating ends of the gears, then there is an adjustment problem.
How can I tell if my differential gears need to be replaced?
Check that there are no chips or damage to the ends and edges of the teeth. The surface of the ring gear teeth should be smooth. If it looks like wood grain, with patterns of scoring all across, this is NOT normal wear and the gear needs to be replaced.
What happens to the gears in a slip differential?
Basically the differential gears are free to rotate relative to one another inside the differential case while the differential case is stationary.
Why do I need to change the gears on my rearend?
If there is too much backlash, the ring gear needs to move closer to the pinion gear. If there is not enough, the ring gear needs to move away from the pinion gear. Just like the side bearings, the pinion bearings are adjusted by adding and removing shims of varying thickness.
Can you set up ring and pinion gears?
Sure, setting up ring and pinion gears can seem challenging, but it really is simple enough that anyone can do it—If they’re willing to pay attention to proper procedures.
When do you need to replace pinion gear bearings?
Just torque the pinion nut to 150 foot pounds and see if that fixes it. It’s very common for the pinion nut to back off and most of the time torquing the nut is all you need to do. If you do this and you have a noise in the rear end then you may need to replace bearings.
What should I look for after removing the pinion?
Once the pinion has been removed, you have your fi rst look at the ring gear and the internals of the gear case. Inspect the pinion straddle support and retainer. Clean the pinion trunnion of any gear oil and debris. The trunnion should be round and smooth without any signs of grooves or gouges.
