Thank You
Yes those Calu. are Handy :
2.5 Inch Drive Shaft - 54 inches long - Has a Max Safe Limit of 3148 RPM
with 1/2 Critical Vibration Drive-Line being - 2802 Rpm - They are Referring to Harmonic's @ 2802 RPM . .
It Calu. to Potential Speed of 52.0 - 55.0 Mph - depending on Tires Size .
Cruising Speed : 40 Mph - 46.4 Mph - all these being in Safe RPM Ranges .
Now the Other Vibration Drive-Line - Item .. ( It Seems everyone Here on this Site has talked about these Angles )
But No Where did I find anything about the Designed Offset - built into the Rear Gear and Or the Transmission .
Many 4 Speeds with PTO or With Out - look to be - Off Center approx 2 " Out Put Shaft ; and the Rear Gear just looking approx 4 " at Pinion . .
with a Carrier in between . . ( Will Measure Soon ) - these Offsets have a Direct Impact on Drive Line Angles . .
