570 PTO removel

I only use my 570 Super for pulling so I've removed the entire PTO in order to get into a lower weight class.A PTO is not required in the division I'll be pulling in so I'll make a plate to bolt to the rear in it's place.
Do I need to also remove the power shaft coming back from the trans with the splined female coupler or can it just stay in place.My fear is that it turns all the time and may not stay put.
If it does need to be pulled out,is it that simple or is there more to it then meets the eye.
Thought I'd better ask someone who knows rather then making a costly mistake.
 
Hi Phil,I would have called you if I'd realized any such part was made.I'd love to have it and I'll call you tonight.Thanks
 
Hello OC
I think I'll keep the PTO intact as it comes in handy if I make changes and want to dyno.The plates are a little weak and won't give me the full HP reading before they start to slip at 100 HP.Still good enough to check my turbo boost pressure though.
Phil has the clutch plates still I'm pretty sure.
 
I pulled the shaft on my 570 and also the shift handle. Did it mostly to get a couple more lbs. of weight reduction. I barely made it into the 5500lb class. It does O.K. in 5500 but hooks up better in 6000.
 
Had another thought: Are you using the hydraulic pump? On a 40-50 the shift lever only disengages the pump while on a 560-570 it disengages the pump and PTO both. If you want to retain your hydraulic system you will have to find a factory idle bearing for a tractor with hydralics and PTO delete which is very rare.

Thanks for the info.I looked at my 40 parts tractor and realized it is different then my Super.The 40 has a support bearing on the rear end of the power shaft held in by two bolts and retaining clips so leaving it in wouldn't be a problem.
My 570 Super's power shaft depends on the PTO's male splined shaft to support it since the bearing comes off with the PTO instead of being held in with the retaining clips.This lets the PTO power shaft wobble around side to side a little even at idle which makes me nervous what it would do at full RPM.
I looked in a 570 service manual which describes how to remove the shaft by taking off the top access cover.I was going to do this,hoping that grease wouldn't run into the clutch area.Since it sounds like you've done this,I'm encouraged That taking mine out completely won't be a problem.
I don't have or want any hydraulics on mine so that's not an issue ether.
With my setup(wide front,light front hubs and 18.4x38's on tin wheels)I can just get into the 6000 class w/PTO.I'm taking the PTO off because I'd like a little more cushion in case scales are a little off.
I can see with my pulling that 6000 is a good class.there are very few pulls around here that have a 5500 class so I'll be satisfied for now with 5800+or- a few pounds until I get a narrow front.
 
I should have mentioned this before but I forgot about the oil getting into the clutch. I had had this concern too so I put a plug in the opening. I wasn't sure if it would get in there but I didn't want to take any chances. I had the top cover off so it was possible to get to it. (barely) If you tractor has hydraulics you can get an aluminum plate from Phil that will save you a bunch more weight. I used a front axle off an E-3 Co-op. The 570 and the E-3 have the same size pivot shaft so it pops right on. I also removed the factory power steering and used the E-3 manual gear on a homemade pedestal. There was a feature on my tractor last year in the Cockshutt Quarterly if you want to see pictures. Vol. 25 No. 2 good luck!!
