1450 Brake leak, looking for input

[USMC_SGT]

Hello All,

First post, been trolling around for a little bit though.

I picked up a '77 1450 in pretty good shape, needed a few things fixed (all the typical quietline stuff has been fixed since I took ownership) when I got it, fluids all changed etc...

The gasket between the rear and hydro needed to be replaced, so I did that and it was good for about a week, then the tractor sprang another leak.

The O-ring for the internal plunger is apparently shot, and I cant seem to get it out from the front, I really don't want to tear the whole tractor apart, because I will end up restoring the whole thing and replacing all kinds of parts "while I'm in there" and I'm not ready to invest that kind of cash or time at this very moment (though it will happen)

SO, as I understand the plunger can come out from the front, but usually wont.

My Idea is to tack weld a bolt onto the face of the plunger and use a small slide hammer to pull in out, once it is out I can clean the face of the plunger up etc....

Looking for some input from some fellow tinkerers!

That should work pretty good. I used good sized mechanics magnet to pull the plunger out of a 73 so I could change the o-ring on it.

Yea I have a couple magnets that are VERY strong, and could manage to pull it out still.

Its been quite awhile since I replaced a brake o-ring but if I remember it wasn't as bad as I figured it was going to be.

Clean the area up and I think I used a pair of needle nosed pliars and grabbed the edge of the puck and pulled it out.

I literally just got the job done, I think the other day I just needed to take a step back and go re-visit the problem, so I did. It was frozen in there pretty well for whatever reason. So I heated the housing up just a tad (and I mean a tad), got in there with some long needle nose and I ended up just pulling it out enough to slip a new o-ring on so I did not lose any fluid. As long as this quik fix gets me through this season, and MAYBE next I will be fine. I am going to restore this ole 1450 and use it forever!

Once I clean her up I will post some pictures in another thread.

Glad u got it fixed up. My 1650 is seeping there too. I have a new o ring already. Does the o-ring go in a groove on the plunger or in the housing?

It fits in a groove on the plunger.. Make sure to lube it before pushing it back in.

It is in the plunger. I just pulled it out enough to get the oring off with a 90* pick, greased the oring and then tapped the plunger back in with a brass drift.

I DID NOT pull the plunger out completely since I didnt want to lose any of the 2 week old Hytran.

I cut the grass and made sure the fluid got nice and hot, checked a little while ago and she is dry as a bone *knocks on wood*
