How does the input shaft work in a car?
The input shaft transfers torque from the clutch disk to the countershaft. It’s supported by bearings that are capable of rotating at very high speeds. The pilot bearing supports the tip of the shaft and allows it to spin at a different speed than the engine’s crankshaft.
How much does it cost to replace an input shaft?
The cost to replace an input shaft bearing may range from $200 to $300. The part itself only costs about $25 to $75, depending on the make and model of your vehicle.
How can I check my transmission input shaft?
Measure the input and output shaft endplay before and after removal. Check end play with a dial indicator fastened to the case and the tip placed against the input shaft. If the reading is out of specifications, look for worn or misassembled parts while disassembling the transmission.
How does a selective washer affect the input shaft?
Typically a thicker or thinner selective washer is installed to adjust input shaft endplay. It’s supported by bearings that are capable of rotating at very high speeds. The pilot bearing supports the tip of the shaft and allows it to spin at a different speed than the engine’s crankshaft.
The cost to replace an input shaft bearing may range from $200 to $300. The part itself only costs about $25 to $75, depending on the make and model of your vehicle.
How to repair a Select O speed shaft?
The first step is to mill a hex where the splines used to be. A 13/16″ hex is ideal as it removes a bare minimum of stock from the shaft. The smaller you make the hex the weaker the shaft will be and this shaft gets a lot of stress.
What happens when your input shaft is worn out?
When your input shaft bearing is worn out, the gear may slip into another gear when you step on the clutch. A bad bearing causes the input shaft to move too much. As a result, the gear shafts are not aligned properly and cannot be engaged entirely. When you go to shift gears, you may feel vibrations coming from the shifter.
How is the output shaft connected to the input shaft?
This is done by using the gears of a gearbox. In a manual transmission system, a clutch is used to connect the engine and input shaft together. When the engine generates power, it has an output shaft which sends the power to the input shaft. From there, the input shaft transfers this power to the transmission system.
