Hydraulic Fluid and Hydro fan for 149
 

Has anyone used Travellers Hydraulic fluid for their IH 149? If so, any problems? Does the Fan on the driveshaft pull air over the pump from the rear to cool? Is the fan mounted with the locking ring facing the pump or the engine? Thanks in advance for your help and have a great day.

Has anyone used Travellers Hydraulic fluid for their IH 149?
I have used it for years with no problems, but I change it every 2-3 years.

Does the Fan on the driveshaft pull air over the pump from the rear to cool?
No, it blows air over the hydro cooling fins from front to back.

Is the fan mounted with the locking ring facing the pump or the engine?
I forget. :RedFace2:

I can't remember either, but the fan needs to blow rearward as mentioned, so the radius of the blades (lift if it were an airplane wing)
would be on toward the front of the tractor
And I also use tractor supply's universal hyd fluid.
Do not use anyone's "303" hyd fluid.
You can also use automatic transmission fluid type"F" as specified by the hydro manufacture, Sundstrand.

Mr Bob, maybe this will help....

Fluid and Fan
 

Thanks to all that replied to my questions and thank you IronMan for the picture. I have trouble visualizing things now and that picture really helps.
Everyone have a great day.

My 129 hasn’t had a fan blade on the driveshaft for years and it hasn’t had any issues. The only problem with my trans is that one of the fluid lines got bent by a stump while hauling firewood on my property, and it leaks a small amount when it’s sitting. The fluid that’s supposed to go in the trans costs a pretty penny and I’ve been filling it up with travellers hydrostatic fluid for a while now. I don’t recommend doing what I do, but after carrying dozens of cords of firewood and cutting 1.5 acres every week during the warmer months it gets the job done

ironman that picture looks like a brand new cub, how do you keep it looking that good?

That picture was from when I did a total resto on it about 10 years ago,
it doesn't quite look that good nowdays....

I just did one so knew this picture & text are on page 2-39B of the service manual.

Ironman that’s a great looking machine. I wish mine still had factory IH size tires.
