the 6way blade on my 350 stoped working, has oil, pump shaft is runing any ideas?

The splines on the coupler that go directly to the pump shaft splines are probably stripped..It looks like the pump is turning, but I'll bet it's not..Rust is the culprit that wear out the splines inside the coupler and the splines on the pump shaft...It's a very common problem..

for the next step i thouht i would disconect the lines @the pump one @ a time and see if oil is coming out or in some one i talked to said he thought their was a aux. pump that pushed the oil up from the trans to the pump in front? also i noticed the level of oil in the glass goes down about a 1/4" when i start the motor then after i shut down the level comes back up? when the thing stoped working i had tilted the blade it wouldn't come back then i was able to rasie the blade once lowoered it then nothig else?

If you have oil in the reservoir than you will get oil by disconnecting the lines at the pump until the reservoir is empty. There is no pump in the transmission on a straight 350 (can't speak for later ones). Oil goes by gravity in the fat line coming from the bottom of the reservoir to the pump. You would be better off checking flow at the control valve. At least you wouldn't lose as much oil.

I will try that, the dozer is a 350C I think its is around a 1973 year thanks
