Part number 10R924A this is the one with the 8 rollers and springs. Took the one out of my parts tractor witch is a 445 also and the ampli-torc is different it has a whole bunch of small rollers that lock on to the hub and looks like there is a different bearing on the shaft that goes into the transmission. I did not get the serial numbers I will try to post them latter. Was the one with the small rollers an update over the one with only 8 rollers. I will be putting the one with the 8 rollers back in the machine. Just wondering what the difference is and what one was stronger? [Reply]   [No Email]

You could buy all the parts to upgrade to the new style. Dad did that to our Jet Star and M5 in the late 1960's   [Reply]  [No Email]

I would be leary myself about getting in just the right spot. Its not like you can erase it and start over.   [Reply]  [No Email]

You are correct when you said the taper roller going into the transmission is different from the earlier tapered roller.   [Reply]  [No Email]
