How is the speed of a drive sprocket calculated?
Dividing the driven sprocket tooth count into the drive sprocket tooth count, the overall sprocket ratio is calculated to be .9743589:1. Multiplying this number by engine rpm gives the speed of the driven sprocket.
Why is the rpm sensor different from the drive sprocket?
This means the input speed sensor rpm data is different from the actual speed of the drive sprocket, and the overall sprocket ratio is matched to the vehicle’s computer system. But knowing that the actual rotation of the drive sprocket is different from the rotation of the driven sprocket makes sense of the data observed from a scan tool.
How do you install a sprocket on a mower?
Reinstall the wiring retaining plate. Slip the stator flywheel over the engine output shaft, followed by the compensator sprocket shim. Place the compensator sprocket into the primary chain, then slip the sprocket, followed by the compensator, into place over the stator flywheel.
What’s the drive sprocket ratio on a 2001 Windstar?
Getting back to the 2001 Windstar example, this vehicle has a 38/39 drive/ driven sprocket set. Dividing the driven sprocket tooth count into the drive sprocket tooth count, the overall sprocket ratio is calculated to be .9743589:1. Multiplying this number by engine rpm gives the speed of the driven sprocket.
How is the drive sprocket secured to the shaft?
The drive sprocket will either be secured with a retaining ring or nut/bolt. When working on a machine that uses a nut or bolt to secure the sprocket to the shaft locking the shaft is imperative to loosening it. There are a handful of ways the sprocket can be secured.
How do you remove a countershaft drive sprocket?
Drive (Countershaft/Front) Sprocket Removal The drive sprocket will either be secured with a retaining ring or nut/bolt. When working on a machine that uses a nut or bolt to secure the sprocket to the shaft locking the shaft is imperative to loosening it. There are a handful of ways the sprocket can be secured.
What kind of sprockets does a Harley Davidson use?
Our PBI and Drag Specialties rear wheel sprockets are made from steel and aluminum to stand up to the stress of a hard ride. For the front of your bike, PBI transmission mainshaft sprockets are machined and heat-treated to maximum load bearing, while their counter shaft sprockets have nickel plating that increases corrosion and wear resistance.
What kind of sprocket is used for two strands of chain?
Double single sprockets: This type of sprocket (Fig. 10) is used in applications where two or more items are powered by a common drive shaft. The space between the sprocket plates is wider than a multi-strand sprocket, and allows two independent strands of chain to engage without contacting each other.
