MF135 Input live PTO Question

So here's the deal. The other day I was putting down the drive giving my daughter a tractor ride on my 67 MF135 perkins gas. I was idleing down a hill, there was a "clung" and both rear tires locked, motor stopped. I shoved in the clutch and it free rolled, I tired to let It out and it just locked the tires. Stopped at the bottom of the hill. I put it in neutral and the Low/High in neutral and tried to start it. It would turn over about an 1/8th of a turn then stop sounding like it had broke a rod.

Fearing engine damage, I removed the motor. It's fine. no damage, full rotation. I'm kind of lost on the next step. I was looking at the input shafts. I've never messed with a live pto clutch before. I notice there two input splines. The center one spins free when in nuertal and locks when in gear. Thinking that's whats suppose to happen. The outer one turns like a 3/4 turn the locks. Both ways. I'm thinking that's bad. Can anyone tell me if that's normal and what I may need to be looking at? Thanks Jacob
 
Sounds like some gear teeth damage on the PTO input side, causing lockup. Does the tractor have the twelve speed MP transmission? If so I'd pull the front retainer/PTO assembly and see what you have. The lower gear can then be turned also to see how it looks.
 
I don't think it's a multipower. it's just has a high/Neutral/Low shifter and the normal gear shift 1-3 and reverse. Are you talking about pulling the main input shaft from the front?
 
MP models the front PTO input four bolt retainer can be removed, but not on the six speed models. Trans must be removed for shaft removal from rear so the input retainer can then be removed on six speed. May need to come apart anyway if the input gears have teeth off like I suspect you have.
 
I bought an MF35 that had the PTO input shaft locked up. It would only turn a short distance in either direction then jam. I found that the spring retainer clip for the 3 speed shift stick had come off and fallen into the gears. By the time I bought it, it would start and run because someone had shredded out the PTO clutch.

Well dan gets the gold star ! looks like maybe the hunk of metal in the gears, could be the spring clip since, it's missing and my spring is broke. I have no gear damage, thanks goodness it just locked everything up, and didn't break anything. Now I just get to put this whole tractor back together lol.
