NF PTO Clutch - spring tension
 

Hi all. First post here. Joined the forum after picking up a 125 about 2 years ago. Done a lot of reading. Lots of good info here. Since then picked up a second 125 and a non running 128 mostly for the implements. It had been sitting for several years. Exhaust valve was stuck open. Its running now but smokes a good bit.

I got one of the decks working and put it on the latest 125. Turned on pto and blades would barely turn. It had worked when i got the mower last summer. One of the spring screws had came loose. Got the pto apart and off the mower with any troubles. I resurfaced the main body of the pto on my lathe. I had a gauge to set the spring tension that was in a box of parts i picked up with the 128, but it was for a WF. I made one for a NF using info I found on this site. I set the tension but wanted to check out the operation before putting it back together. I found a piece of scrap close to the size of the bearing and put it in my vise. It takes very little compression to disengage the clutch. Probably no more then 1/16". The spring is the type with the turned down or curved feet where it contacts the clutch body. Does this sound about right?

Thanks. Todd

Yes that sounds about right. It takes a very small push to disconnect them. Mike:beerchug:

Thanks. I was hoping that was the answer. Didn't want to reassemble just to find out it still did not work.

I know everyone likes pictures, so here are some photos of the PTO cleaned, painted and assembled along with the NF gauge I made. Also, one of the PTO in my vise checking out its operation.

Very Nice Work!:IH Trusted Hand:
