1650 pto bolt
 

I've been scouring the search engine and the web in general. The engine on my 1650 didn't have a pto on it. As I am installing a new one I need to know the bolt size. I've tried a couple I have on my m18s to no avail. Does anyone know the correct size bolt for this? The engine came from a cub 1650 puller so it is accurate. Thanks guys.

I believe the bolt is a 7/16 nf x 1.25 long. Need thick washer and spacer too, IIRC!

Thanks looks to be fine thread. I have the washer off a mag that should work. I am slightly worried that I will need to retap it.. Fun conaidering its in the tractor and I have no desire to pull it...blah

Remove the grill assembly for better access and use a tap socket to give you some extra space when "cleaning" the threads.

Yeah, been down this road before... Really hoping I was going to be able to take the low road this time. Unfortunately I have to remove quite a bit to install the new extreme clutch....:bash2:
