IH cub cadet 1650 where can I find a pump rebuild kit
 

I bought a cub cadet 1650 it's my first one and when it is running the deck lift works fine it will pick the plow up and drop it but when it comes to moving it doesn't.want to even at full throttle and when it decides to move it goes to extremes then you can kind of control it. Any ideas of what it is the fluid is full and not really dirty. But smells pretty bad. Thanks in advanced

Change the fluid and the filter. Also check the condition of the trunnion to see if it's worn causing slop.

Rear end
 

I plan do do that this weekend what would you use for the fluid I have hydro fluid but is there anything special I should use

I would do a general internet search along the lines of "hytran vs generic fluid". Hytran is what is recommended by Cub Cadet, but is more expensive than generic fluid.

This topic has been debated many times before. Here are some discussions from our forum

Don't forget to get a new gasket and be sure to wash the rear end housing out well while you have the cover off.

Hydro fluid
 

I ended up finding a used rear and pump from a guy in Maryland for 75.00 but after I put it in ot only seems to want to move at low idle an keeps foaming the hytran. I'm ready to sell this 1650 and get a gear drivin cub cadet ;)

Did you change the fluid and filter in the one that you just put in?

Did you change the fluid and filter in either one of them?

It seems to me that the foaming is the fault of the hydraulic fluid, rather than the pump or the transmission. I agree, change the fluid and filter. Change it again, if you still have foam.

The great oil debate continues, but in these transmissions, use HyTran. We know HyTran works. It doesn't foam very much and it absorbs moisture.

HyTran is, In my opinion, worth the money. You won't have to change it twice.

Foaming can be caused by fluid type, but not usually. It's generally caused by cavitation. Air entering the system on the suction side. Low fluid level is a likely cause. So is a hole in the system. Hytran can foam just like any other oil when air is introduced.
