Hi, I've been going through this old 185dt, and noticed a bolt that won't seat, it sticks out a quarter of an inch or so and weeps transmission fluid. Looks like a set screw? It's about on the opposite side as the fill level bolt, similar height (right side, down by my right foot when seated). Can't find it on any of the diagrams.

I have the same bolt on my L185F on the brake pedal (right) side. I looked through the illustrated parts list and never saw anything that illus the right side of the case so have no idea what that was holding.

The bolt head is tight against the case on m and it is a few inches to the rear of where the oil level plug is on the opposite side.

here is the clutch side. Notice the red plug for oil level is right at the front of the foot rest

Find the diagram that shows the reverse idler and the shaft it rides on. I'll bet that bolt is a retainer for that shaft. When properly installed it fits over a flat spot on said shaft and keeps it in place.

You may need to remove a shift cover to see the shaft down in there. You may need to move the shaft a little to get into the right spot so the bolt threads in all that way.

This has come up before If I remember right.
Looks like someone lost the original and replaced it.
It need to be shortend and replace the sealing washer with a lock washer.
Put a little RTV, or pipe dope on the threads just under the head to seal it up.

Thanks for the input, folks. Added the above screw to my next messicks order, we'll see how they compare.
Please post a picture of that when you get it please.

I was going to suggest that was the part but thought that reverse shaft would be rotating and couldn’t find any pictures to confirm what that part looks like.

I believe the problem is that the shaft that it retains has turned. Not allowing the set screw to go in all the way. I have had them where people took them out thinking it was the level plug. You may be able to put some sort of pic into the hole and rotate the shaft to the spot where the set screw will go in complete. The other problem may be that the shaft has moved forward or backwards.

My problem with his bolt is that it has threads on the pin portion, which makes me think someone just made the pin out of a bolt and it's just too long.

Will do, may be a couple weeks before I have enough stuff for an order.

since you are new…

Sorry for the basic instructions but sometimes people just don’t know what we are talking about!

If it won't thread in and bottom out then you have to take the top off and get the shaft to line up properly to close the gap.

Looking at the diagram posted, it would appear to be the reverse gear that the shaft rides on, that the bolt holds in place.

I'd try to get the shaft to line up by jacking up and supporting the rear end, and then running the tractor in reverse to see if the shaft will spin slightly. Be ready with a screw driver or thin punch to shove in the hole to capture the shaft while you shut down the engine.

It already had a bolt tightened down into the shaft, so my bet is that it dimpled the shaft just enough that it's not goin to spin easily. ;)
