I need the 8 tooth with the steel sleeve, or do I just press the new gear onto the sleeve? Link to comment Share on other sites More sharing options...

And I don't know if you can press the gear off the sleeve. I pulled the drive gear on Big Blue's BW1345, but I didn't swap it, I just put it back. But I from the advert that David found (thanks, David!) it looks like they come on the sleeve. Link to comment Share on other sites More sharing options...

1986F150Six Posted October 19, 2021 Share Posted October 19, 2021 Thank you very much By the way, Jonathan Donald [Ford F834] has experience with these gears and I believe has reported that the gears wear when there is too much friction caused by inadequately lubricated speedometer cables.

How do you calculate the right gear? For example, when you go from 31 to 33 inch tires? Link to comment Share on other sites More sharing options...
Gary Lewis Posted October 21, 2021 Share Posted October 21, 2021 How do you calculate the right gear? For example, when you go from 31 to 33 inch tires? By using the calculators at Documentation/Driveline/SPEEDOMETER GEARS, CABLES, & SENSORS. But there are three of them so here's what they are best used for: Correct Speedo Error: This one is for when your speedo is reading incorrectly. Just input what the speedo reads at 60 mph and what driven gear you are currently running and it'll tell you the driven gear you need. Set Up Gearing: This one lets you change anything. Input your "old" setup and then change something in the "new" setup and you can see the speedo cable speed, which you want to be as close as possible to 1000 RPM. Change tire size, drive gear, driven gear, or axle ratio. Comparative: Two tabs. The Gear Calc tab is pretty simple but shows what adapter box ratio is needed. The Original tab is simple as well. I'd use the Original on the Comparative tab as it is the most simple one. Again, you want the speedo cable to be spinning at 1000 R's at 60 MPH.
