414-8 transmission leak

Recommended Posts

F. Marra 17

I have a late 80's 414-8. my transmission has a slow oil leak. it leaks slow so its hard to see where it is coming from. i get a small puddle/stain on the floor center under the trans after a few days of non-use.  is there a usual problem area that leaks? or is there anyone in the NJ area that can be recommended to repair the trans? I am sure due to its age that gaskets or seals may be shot.  the tractor sat for 10+ years at my office on a shelf.  It has ran well the past 3 years for me.  I would like to fix this leak if possible.  Any advice or help is greatly appreciated.

 

THANK YOU,

 

Frank

Hey Frank,

 

the 8 speed doesn’t have too many leak points.  Input shaft, brake shaft, axle shafts and case gasket.  The gear shifter has a boot and the hi-low shifter has nothing.  Not too much fluid gets tossed that high to leak out.

 

My best suggestion would be to wash the transmission well with a degreaser and or a pressure washer.  Put some masking tape under the shafts mentioned and near the case gasket.  Run it a while, check the tape for moisture.  That should indicate where it’s coming from.  The key is to not let the leak point to saturate everything before you check.

Short term suggestion - cardboard underneath keeps the floor clean...

Retorque the 5 or 6 bolts that hold the Trans Cases together.  MAYBE an easy fix.

I bet it's either the brake shaft or input shaft. Tractor sat for a while, seals hardened. Now running the brake and input shafts spin pretty fast. Prolly tore the seals. My 953 started pissing like a racehorse and left a puddle right in the middle underneath the case. Input seal was almost non existent.

Thanks for the suggestions, I have some old carpet underneath for now, and have torqued the bolts in the past.  ill try the tape method to get a better idea.  i'm using the tractor to snowblow right now so i don't want to go too crazy disassembling until the winter is over.

Keeping a little extra fluid in it won’t hurt anything either, better to have extra than not enough!

      Not sure on specific model. This 8 spd came attached to a plow I bought. It had some water in it for a couple weeks according to the prior owner. I drained it, sloshed some diesel in it, drained that, then filled with fresh oil. Spinning the input shaft by hand, I can see the axels turn. Hasn't leaked any oil. I'm not really interested in shipping, so I'd prefer local sales.

      I’m looking for a transmission dipstick to a D-180. Let me know if you see one.

      1979 C 8 speed tranny model with 14 hp Kohler engine and plow attachment, Runs good but ignition switch doesn't work and have to jump start over solenoid. Right rear wheel hub lock bolt won't hold and hub slides in on axle. Not sure why, out of round hub axle hole? Still use it regularly though with hack fix. Plow blade is badly worn out along the knife edge.

      Hey guys,I have a dilemma I need some help with. I have a 1969 GT 14 that I replaced the transmission and pump on. For about 2 weeks afterward everything worked great, but while mowing at a pretty good pace I noticed a shudder and the tractor slowed a little but not bad. The more I rode it the slower it got until it barely moves. What stumps me is the hydraulics are still very strong,as in I can back the 3 point under the bumper of my truck and if you lift the arms all the way up the front wheels of the tractor will clear the ground. Have checked the tow valve and checked the internal filter,but no luck. I have also checked and replaced the forward and reverse bypass springs and the lever is moving the cam to full travel, forward and reverse. Any help would be appreciated.

      I think I am selling my 1987 414-8 with plow, weights and chains.  Now here’s the story on this one. A long long time ago, I was searching for a snow plow for my 416H.  In that search I stumbled onto a forum which was one day old.  There was no name of the forum, just whtractor.15.forumer.com. Trying to learn more about snow plows I started conversations with one of the active members on the site, let’s call him Mike.  Mike convinced me I didn’t need a plow, but an entirely new tractor.
       
      About a week or so later, I found this 414–8 for sale, and bought it.  I now had my plow and could plow the driveway. So what happened with Mike @Sparky and this forum I spoke of? It grew a little bit, and we now call it RedSquare, and for sale is one of if not THE reason RedSquare exists today, so you can own a piece of RedSquare history!
       
      About the tractor: 1987 414-8. Kohler M14, runs well does not burn oil. Everything on the tractor works as it should, but it is a worker. The plow is a 48” with a custom made scraper blade, made from heavier stock than original. For the past several years, this has been a dedicated plow tractor, so it hasn’t seen a lot of work, but has also sat outside (under a tractor cover) so lots of let’s say, patina going on.  
       
      I a, selling because I just picked up a 416-8, and that will become my winter plow / blower tractor.  I am looking for $550, but like I said this tractor is a bit of a legend!

      I have cleaned it up since the pictures were taken.
