I had a thought looking through the TSC book.

Anyone ever tried running a hydraulic pump of the PTO on the trans?

Seems that if it was run that way the pressure would increase as the rpm's came up.

Just a thought not sure if it would work.

Input?
 
I'd take a sec or two for the pressure to come on since its not a live pto, don't see why it wouldn't work sept for the cost for the pto, 12v pump can had at surplus stores for 4-5 bills.
 
I because most of the pumps/pto's rpm limited. Most setups that I have seen or worked on stated not to exceed 1200rpm so I am not sure what would happen on one spun up to 5k plus.
 
And we're not supposed to turn the engines 6k either.

Seems like a solution for those of us that cant loose their power steering pump.
 
True but I have seen hyd pumps and pto bearings that were trashed because the driver would sit there the entire time on the gov while the trailer was unloading. Not saying its not going to work. In fact I thought about doing this some time ago as I have seen generators and welders that were powered off of the pto. I just didn't need the water injection as the truck wasn't a puller. The pto's come in different HP ratings to so the might matter. But there are a bunch of them out there so you might get one cheap. They are shimmed to the trans housing and that is how you control the gear lash when you install it so keep that in mind when you go hunting.
 
On an allison the pto gear is on the C1/C2 clutch housing which is coupled to the input shaft directly. The gear is, geez, maybe 8" diameter or maybe a bit more. The gear coupling to it would have to be smaller just to fit, so the output shaft rpm would be at like Ludicrous Speed if you were hummin' down the track at 4000+ rpm.

Don't know where the PTO comes from on a Dodge, but if it's similar, it's way too fast.

If you did it with the right pulleys/sheaves I bet you could go right off a driveshaft and get reasonable rpm.

And there's my stupid ideas for the day.
 
Way to fast, output shaft speed on pto would be out of this world. The pto just arent made to spin that fast.
