Re: HYDRAULICS
Check the oil dipstick and see if the level is high. If it is, the seal on the pump shaft is leaking hydraulic fluid into the crankcase. If the dipstick level is normal, check the level in the TC block and add hydraulic fluid if it is low. Was it working okay previously, or slow or jerky?

Re: HYDRAULICS
The crank case is high, just thought the old feller I got it from had put in to much oil. I have never seen it work just the the cub cranked today for the first time in 15 years or there abouts.

Re: HYDRAULICS
It's hard to tell if you just need to replace the shaft seal or possibly rebuild the pump. Here's a link to a "how to" that shows the entire procedure. The o-ring replacement is about halfway through the how to. TM Tractor sells the pump kits or just the shaft o-ring. You'll need to change the crankcase oil and filter. You'll have to drain the TC block and manifold lines in order to work on the pump. I would suggest the whole kit or you may end up replacing the hydraulic oil a second time if the shaft seal doesn't fully fix the problem.

Re: HYDRAULICS
Before I tore into it to far after setting 15 years, I'd get the engine oil to the correct level (oil change) and fill the TC. Then see if it leaks. Most likely it will but then you will KNOW, not what we think is most likely or what we think it might be.
When you have a flat tire do you just slap a patch on the inner tube somewhere? Or air up the tube, find the hole, and then patch it? Always figure out what's broke and fix that, otherwise you may use a lot of patches before you get the leak covered.

Re: HYDRAULICS
In other words, Scrivet, you're saying just check the fluid level? You know what they say about assuming something. Can't deny it, I made the assumption that had already been done.

Re: HYDRAULICS
In a broader sense I'm saying NEVER start fixing anything until you KNOW what is broke, (or what's broke may be you from all the parts you've tried). Figuring out what is broke gives you a better understanding of how it works, which makes fixing it the next time quicker and easier. Applies to most anything not just Cubs.
