I purchased this 3910 recently and today I'm replacing the starter safety switch. I whipped out the I & T #43 and looked at the process. OK fine.
My curiosity has existed for a long time and today, while in the area of the tranny, it got me to looking at just how does a gear driven "Independent PTO"
get driven?
Looking at the tranny exploded view it's a no brainer looking at the dual shafts and all that allows the function to happen. The problem arises with the
drive mechanism.
Looking at the exploded views of the clutch and tranny, I see one primary shaft coming out the front of the tranny with a spline that fits into the splined
hub of the clutch disc.....one shaft connecting the disc. No other connection point that I can see for the PTO drive. Looking at the front end of the
tranny, you see how the dual shafts are hooked together and some where in there is the sliding sleeved spline that engages the output PTO shaft when
you move the PTO lever.
When the pressure plate is compressed, like when clutching to shift gears, the disc is separated from the engine's flywheel....ok fine.
The kicker: That being the case, with only one input shaft, how does the PTO get driven when the clutch pedal is depressed?
Something to do with your morning coffee. Wink!
Thanks,
Mark
