There is one tooth difference per gear. Late B 31-73 teeth, early 39-46 has 32-72 teeth. So there is about a 5% reduction using the late B set, but there is a problem. It would be easy to maching a bushing to get the late B pulley gear on the early pulley, but the shaft/spline size is different between the reduction gears. The late B has a larger diameter shaft. The only thing I can think of doing to make it work is machine the outside of the early gear down to the ID of the outer ring on the later gear and machining it for the dowels as the late gear uses. If anyone has done this, id love to hear from them. Thanks Jake   [Reply]   [Send Email]

I have a 45 that id like to slow down a bit. How much does it affect the gearing? Does it give you a creeper gear or does it just drop it a percentage? Also does the later first reduction gear fit on the input shaft to the transmission without any modification? Thanks for any help Jake   [Reply]   [Send Email]

I am trying to slow second down for div 3 and shift into 3rd for div 4. Saying that, does anyone know what needs to be done thanks!   [Reply]   [No Email]

Too bad everything wasn't this easy.   [Reply]   [Send Email]

He shouldn't need creeper gear. That B he has should run at lesat 3-4MPH. Once you get out of 1st gear, they are similar. According to the book for the 41-46 it's 2.5, 3.25, 4.25, 5.25, 7.33 and 12.5MPH with 10-38 tires at 1150 RPM The later ones (47-52) are as follows 1.5, 2.5, 3.5, 4.5, 5.75 and 10 MPH with 10-38 tires at 1250 RPM's   [Reply]   [Send Email]

Some machining required. If there was an easy way, I'd swap you. I could use something between 5th and 6th. The early 5th gear would be pretty nice.   [Reply]   [No Email]
