Recently bought this old girl. Foot clutch pedal had zero free play so I shortened it a couple turns and still had good disengagement. Clutch did seem a bit "soft" but hard braking in 4th gear causes no slippage. Topped off the hydraulic oil, added some oil to tranny and rearend. Hooked her into my 7 ft flail mower and went to work. Half a dozen rounds and the clutch began to slip so I quit and went to shop. Took lower plate off the clutch housing and everything was oil soaked. Then noticed hydraulic oil way overfull. I hadn`t even filled tranny and rear diff to overflow levels. Gonna drain some hydro oil out and bathe clutch assembly with lots of brakleen. Man I hope I don`t hafta pull this motor out! Ideas?

Seems like there is a vent hole inside the clutch housing for the hydraulic compartment and if overfilled it might empty into the clutch compartment? Others more knowledgeable than me will chime in if I'm wrong.🙂 ------------- 1957 WD45 dad's first AC 1968 one-seventy 1956 F40 Ferguson |

| I noticed my ground speed slowing and "whirr" of mower decreasing. I shut PTO off and tractor would move OK and it pulled the steep hill back to shop in low gear. Gonna pull starter and upper bellhousing plate off to clean it out. Wished I had a steam jenny. Doubt my cold pressure washer would help much. Hoping a case of brakleener will work. |

You are correct sir! When I removed upper bellhousing plate, there is a brass 90 into the housing with a metal splash plate under it. Oil level was covering half the input shaft. Drained the hydraulic oil (nasty looking stuff too) and soaked the clutch assembly with 6 cans of brakleen. Considering starting engine and shooting a degreaser into bellhousing from underneath with clutch pedal locked into disengage position. What could go wrong other than me getting soaked? MAN I`m hoping this works!

| Hard to get oil out of linings. Hope you get lucky. Heat works better than Brakleen. Old timers used to use a torch to get oil to rise to the surface. Wouldn't recommend after that much Brakleen...lol |

I think your WD just wants you to become more intimate with it... :D In the end you'll just replace the clutch anyhow, therefore all the time money and cussing between now and then will be a waste. Just my thoughts, for whatever they're worth. |

I am afraid that Tim may be correct. It sounds like you are on a path towards and new clutch. And while your in there ........:) Regards, Chris ------------- D17 1958 (NFE), WD45 1954 (NFE), WD 1952 (NFE), WD 1950 (WFE), Allis F-40 forklift, Allis CA, Allis D14, Ford Jubilee, Many IH Cub Cadets, 32 Ford Dump, 65 Comet. |

Well, I did. Did the best I could as clutch recessed into flywheel with no edges exposed. Then I fired it up with clutch disengaged and shot degreaser onto center of clutch. Left it sit a few days and last night I finished the 12 rounds of field with no issues. Clutch is soft but was when I bought it. Probably pull motor this winter and replace it if tractor proves itself worthy otherwise for me. Got lucky this time but WHY vent the hydraulics into the bellhousing?! DUH! |

Because it was the easiest place to put a vent  My Freeman loader will go all the way up without the hydraulic level being up to full. Just don't over fill it, or get inside and add a drain tube to the vent , to bring it down and outside the housing.------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Glad the Brakekleen worked for a while. Maybe you can enjoy the tractor for a while. When the weather turns to crap, you can fix it the right way. ------------- sometimes I walk out to my shop and look around and think "Who's the idiot that owns this place?" |
