5610 II neutral safety switch

The neutral safety switch quit working on my 5610 II. I bypassed it for a little while. After removing the top of the transmission, I noticed the pin 30A was sheared allowing pc. no. 60 to move almost all the way off the end of shaft pc. no.30. This movement allowed pc. nos. 62 (steel ball) and 63 (plunger) to fall out. Attached a magnet to a rubber hose and fished around in the bottom of the transmission. Didn't pick up anything. I am thinking those 2 pieces have migrated. If so, where could they go and would it be harmful if they stayed in the bottom of the transmission? Could they migrated to the pump and cause damage?

If those parts haven't caused issues by now, they likely won't, but that's no guarantee of course. There's always that 2% chance that something bad could happen, and let me tell you, if a steel ball gets wedged in between two gears, it will make a mess.

The parts likely migrated their way into the rear axle housing by now if you couldn't sweep them with your magnet. Have you tried draining the rear axle oil into a bucket and listening for a clunk?

There's no way that the parts will get into a hydraulic pump because of the filters, however I might consider removing the rear hydraulic pump for a look see. Or, easier yet would be the 4-bolt round cover on the LH side.

You didn't say whether or not your tractor is 4WD. If it is, I would say that finding these pieces suddenly becomes more urgent. The transfer case gearing will not win the battle with a steel ball.
 
Got back on the hunt for the missing parts of the neutral safety switch assembly. Looked at the diagram above and it looks like there is s shallow barrier between the transmission and the rear end. Since there is a drain plug pc. no. 6 forward of that connection. Decided to try this drain first. Put 5 gal. bucket with screen over the top. Wedged a 6" extension between the bottom of the tractor and the screen creating a low area in the screen. Pulled the plug and after about 2 gallons of fluid drained out, I saw the steel ball and the little cylindrical plunger. Put the plug back in and also noticed the part of the cotter pin that broke causing all this problem. Now I can rest easy. Thank you Bern. for pointing me in the right direction.

That's awesome. What a relief I'm sure it must have been for you.

I typically just drain the oil into a clean bucket and listen for a clunk. Even if I don't hear a clunk, I sweep the bottom of the bucket with a magnet.
