NF cub hydraulic lift help
 

Hello everyone, I'm brand new to this site so forgive me if I'm not doing this right. I have an original cub cadet handed down from my father in law. The tractor has a hydraulic lift pump for the snow plow (never had a mower deck), the issue is that the blade only goes up intermittently. I'm hoping it's just a fluid level problem, but, without much experience with this sort of thing, I can't figure out how to check or add fluid to this pump. There is no obvious holding tank for fluid. I'm told this was a dealer added pump back in the 60's when it was bought by my wife's grandfather. I appreciate any help. Thanks!

Pictures would help a lot... :beerchug:

This is very helpful....

See page 10 for the oil, I always use hytrans ( non synthetic )

:Duh:
Sorry bout that.
I should know that pics are never a bad idea.
Let me know if y'all need any more.

I have never seen that set up before in my life. You either have something exceptionally rare or a very well made one off. Hoping someone here can help you out.

Very nice "O", that blade looks like nothing I have seen either. But very cool:beerchug:
More pictures, PLEASE.

:BangPC:More pics? No problem. Just finished making my own snow chains...Whatcha think? Also, is that my serial number? What year is it? All I really know about these tractors is that they are pretty cool. I'd take this "tractor" over my uncle's 10 year old "riding mower" any day. Thanks in advance for any help.

Your serial # is on the gear reduction housing on the right side of the tractor. It is stamped into it. It is either 3,4,or 5 #s

Welcome to OCC! That's a nice O, you have there! I've never seen a hydraulic setup like that either. :beerchug:

From what I can find it is as stated, very rare, or its a ford or Bolens lift unit because it's mounted backwards from the stock cub ones. Now, even though it's a different pump, it should have a plug on the cylinder like tank on the pump, the tank may have been rotated and the plug could be on the bottom or back side where you can't see it.
Here is a pic of one on a bolens. Looks like your cub has very well made mount on it:bigthink:

:Welcome2:

:Welcome2:

Nice setup! I would love to see more pics of the drive cup on the dash tower side of the engine. I bet the fill hole is on the under or side of the pump. There's two nuts on the angled pump side that you can loosen to rotate the pump housing around. It should be in the 2 o'clock position. Be easy rotating it around so you don't damage the large o-ring. CCspecities.org would have replacement if yours gets damaged. A cub cadet pump would be mount differently then yours but it it works and your happy with it that's all that matters.

Thanks for the help, guys. I still haven't found out the make and model of this pump, but I did take the tank off by removing the nut on the end, then the tank unscrewed from the pump. There is no fill plug at all, and there was a minimal amount of fluid. I'm thinking I'm going to get a rubber plug and drill a hole in the tank to fill/check fluid. Any thoughts on if that will work well enough? Or should I find some sort of sleeve/threaded plug to use? the tank is only about 24 ga. sheet metal so not thick enough to drill and tap for a threaded plug. I really appretiate any suggestions on what would work best before I go drilling holes. Thank you.

Duke, I'm not quite sure what you mean by the drive cup. Are you talking about the drive pulley on the pump?

Problem solved, I think. The tank does not have a fill plug, but it does have one on the business end of the unit. It's the small, square headed plug in the picture close to the pulley. I used a small bulb syringe to fill it to the level of the plug. Plow lifts and lowers like a charm, all I need is some snow to push. Thanks all, for the help nudging me along to get this thing working. Guess it was just low on fluid, now I know how to check it.:beerchug:

I should have said the pulleys on the back side of the engine.:bash2:

Awesome news!:beerchug:

Cool deal! Glad you got it straightened out.
