Laying under the tractor trying to figure out why the clutch won't disengage and I noticed oil on the bottom of the trans. Nothing unusual but it got me to thinking that maybe I was looking at the wrong end. Removed the filler plug and couldn't detect any oil. I removed all 3 plugs and drained maybe 3 quarts of oil. Filled it with 8 qts of SAE 20 non-detergent. Problem solved. Disengages in seconds. Can't believe I split it 3 times unecessarily.

I guess after sitting for 35 years with only the rare trip down the driveway, it leaked down and I never checked it. I can handly wait to see where and how much it leaks.

I'm now going to replace the oil pan gasket and discovered that the rear two bolts are tucked back in the bell housing/torque tube. Hard enough to get them out so I can't imagine how hard it is to get them started. Any slick tricks?

Can you use a swivel socket? I used 1/4 in drive one on another engine.

I have small hands and don't have any problem getting those rear bolt out or back in. Even as they cramp up sometime now that I'm knocking or 70s door.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Frank... the transmission oil level was causing the CLUTCH to drag ?? I never would have guessed that one !!

I guess the HIGH OIL level would cause a DRAG on the gears and shaft which would make some difference...

Like them all, but love the "B"s.

If I understand correctly, with no oil up high enough to reach the gears and slow them down quickly once the clutch was disengaged, they just kept spinning/coasting down for a long time?
