LU 4 Winch Clutch Shaft Plug

Working on a Braden LU 4 Winch and will need to remove the clutch shifter shaft. Have not yet pulled the plug out of the bottom of the clutch
housing to remove the snap ring on the clutch shaft. My question: Is the 1.25" plug basically the same as a freeze plug with a cup shape?
For a replacement would I just purchase a 1.25 inch freeze plug? or is in more of a convex disk that does not have a rim like a freeze plug?
Thanks

I used a Dorman 550-017 plug.

when I restored mu LU4 about two years ago, pulling the shifter rod out was a nitemare. Someone must have banged on it with a hammer to move the clutch. Got a replacement I think from VPW, and then separating the main housing halves with a rusted fused minn shaft/dog was just as difficult. Getting the thing apart was far more work than putting it back together. Plus, mine had broken keys in the main shaft, had to have a machine shop get them out too. I used sticky grease to hold the dog in place when I assembled it back together. IN the end, my shifter shaft must have been a little longer than OEM, because I could get the bottom lock ring in, but not have room to put a plug back in. So I packed it with grease to keep stuff out. In the end, it works fine. Good luck with your effort, hal

Hal,
Did you include the spacer that goes under the plug? I ask, because ours went missing in the parts washer for a while and lead to a bit of head scratching.

My spacer was missing once I got the plug out. I had to make one up to fit in there.

I don't remember now, there is a spacer of sorts under the top of the shifter handle. I put in new seals, plus the lock ring on the bottom of the shaft, but just didn't have room for the plug you tap in to seal the whole thing. My TM' s are over at the "hanger" or motor pool as we call it, so can't look it up now. it was a lot of work with clamps and every sort of tool, to get the halves apart. Charles Talbert has a lot of info on tricks to make it all work when one, plus others like me have posted about this project too on this forum. Good luck. Rust on the insides can make taking it apart a real challenge. hal

The spacer goes under the plug, it's just a thin piece of tube that goes in the plug's bore. It holds the plug off the floor of the bore (and off the clutch shaft) and allows the plug to be deformed to seal. I didn't measure mine but I'd guess is was a mild steel tube around 1.240 OD, .05 Wall and about .25" tall. If you don't use one you won't be able to expand the plug.
