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!

      I have no understanding of what it is like to push one of these when the trans is disengaged and motion lever is in the forward position as the manual mentions. I hope this is not old ground and that I am not cross posting. With the trans disengaged and motion lever set forward there is still something spinning in and about the transaxle that is giving resistance. I need to know if this is normal or if I should be expecting more of a free wheeling experience. In effect, much less resistance. Thank you for comments or pointing me to a topic that already covers this.
