1655 pto again

young tractor · Feb 14, 2015

Hi guys,
I have been working on the pto of my 1655. I can't get it to shut off unless I put a tremendous amount of pressure on the arm. I runs at the same speed whether it is engaged or disengaged. When I took the cover off, the big snap ring was not in it's groove, so I put it back in the groove and it still doesn't disengage. Could it be adjusted too tight. I don't have a pull scale to tell how many pounds the lever is at. Is there another way to test it? Could I back off the tightness one notch and see if it helps? My only other guess would be the the brake washer is really worn. What do you guys think? Thanks again for your help

I am not sure what you call the big snap ring. One notch is not going to make that big a difference. Like I told you before post a phone number. I would say you need some clutch plates. J.

When you cannot get the PTO to stop, it is because some or all the discs are warped taking up too much space. Warp discs are from over heating, when trying to start a machine that has been slugged. The PTO needs to come apart and all warped discs replaced. I have repaired PTO's with used discs from other tractors, but the need to be flat and straight. 1850 discs are the same. Be sure to look at the order of the discs and number before you take it apart. Earlier ones had fewer discs if I remember.

   Take centerplate's advice, write down the number of disc and separator plates, and order.   Make sure disc and separator plates are flat, I can almost guarantee they are not.   When you assemble the clutch make sure that you have 0.120" clearance between any two disc and separator in the disengaged position.   Assemble with less than 0.100" clearance and separator plates will warp again.

   The disc and separator plates were originally purchased items from a vendor.   Aftermarket part may or may not be of the correct thickness.   Remember the clutch has pressurized lube oil flowing through it from the transmission pump.   Cold oil this time of year makes a good fluid drive and you may not be able to stop it until the transmission is warmed.

   Should you not be able to get the desired clearance, there is a little machining that can be done to get proper clearance.   Post back here and we will outline the parts to be machined.

Thanks guys. I am going to dig into it this week.

Just a thought have you tried it with it hooked to a piece of equipment? Seems like those PTOs will gum up or something after a long time of not being used run them with a baler and they start to work OK.
