Jubilee w/ Sherman Questions

duckrock · Jan 24, 2019

Determined earlier this week that the front trans seal is leaking into bell housing. But, I have no idea how bad it really leaks because I haven't owned the tractor very long. I'm
wondering what others think about putting a little simple green or kerosene into bell housing through timing hole to thin out and clean up the watered down trans oil. Then keep an
eye on the trans oil to see if it is necessary to split the tractor to change out the seal.

Also, I've got a step up/down Sherman in this Jubilee. I've heard that the Sherman also changes the PTO speed, so even though the ground speed is slow enough for a tiller it still
doesn't work well. Is this true? Sherman tag on steering wheel makes me believe you can still maintain PTO speed by increasing throttle.

The kerosene into the bell housing is not a good idea.

Yes, the auxiliary Sherman transmission does change both PTO and ground speed. Your Jubilee will still be poorly suited for use with a PTO driven tiller.

Agree with Dean. If the tranny's seal is leaking fit it or keep dumping oil in, your choice.

Thanks. I guess I'll split it twice then. Before the trans to fix the leak. Then behind the trans to install my Everette trans. That won't change PTO speed.

Questions about splitting before the trans to fix the leak: What is the preferred/easier method. Remove tin, front axle, and engine. Or, unbolt steering box and engine to move the entire assembly forward?

As long as the drain hole is open, yes you can spray simple green into the timing hole to clean out the bottom of the bell housing. Just make sure it drains out and all will be good. It is important the hole stay open, and keep the bell housing from filling up with grease, oil, or hydraulic fluid. AND... one drop of oil on the ground make a pretty big spot. So you can park it over a pan to see just how much is leaking, and how fast it leaks. Lots of tractors ooze at the rear seal on the engine, but its usually not enough to worry about over a year or more in fluid levels.

I have agreed with that for years. In the early 60's my father acquired a 3 point hitch 2 gang rototiller. Our 8N (now mine) could barely pick it up and did very poorly trying to till our annual 1 acre garden.
Last summer my neighbor's son bought a rototiller at Tractor Supply and put it behind their Jubilee. Even though I knew that it would not work, I helped them attach it. Dang! It worked very well.
They were working down last years garden and there was not a lot of debris. He pulled it in first and then in 2nd.
So, I have to re-evaluate my belief. I have not sought out the specs on that rototiller.

I will usually block up the engine, unbolt the steering box and with a come along on a ceiling beam raise it up a bit so the trans will clear with a floor jack under it just roll the back half of the tractor away, of course you will need to unhook the hydraulic on you jub. Here's a 640 I put a clutch in. A bit harder because of the loader and power steering but even with that it wasn't that bad.

You can also see on this video was the split for the back half look like using the same split method.
