Help with a 169

[Dan Colonel]

I have a busted up cooling fan in front of my hydro unit and am unsure of how to get fan replaced.
If I remove drive pins at each end of drive shaft and take apart the flex coupling in the center can
I remove shaft and fan? Or is there a better way ? Thanks everyone…

 

[jkoenig]

That’s the only way I know of, but my only hydro is a 782.

If you are as lazy as I am you might want to try this. The fans are pretty cheap so I thought it was worth an experiment. A better way to hold it on might be a 2 piece clamp collar from McMaster, it was very challenging to hold the 2 pieces in place whilst wrestling the snap ring

Take it apart and do it right.
You will likely find other issues/areas that need attention while doing so such as these for example....

 

[Stu]

That is the right way to do it. In my case I had had it apart fairly recently but had chewed up the new fan mowing my rough acre. Lotsa sticks plus I like to use the whole tractor to push back at the brush.

Thanks for your help guys. I ordered some parts from CC Specialities ..hoping to not find other problems but it looks to be all original parts..

Might be a dumb question, how do you get the snap ring on the shaft without taking the shaft off

which way is the camera pointed?

I believe it's the same ring that held on the original

Welp,I never thought of that. Good answer.

 

[Stu]

Yup I just left it on. The old fan had maybe one or 2 blades left, I think I just sorta chomped it off. Camera is pointed toward the hydro. (1250)

Still working on the 169 so here is another question.
Why would the valves on top of the hydro have one tall one and one short one with a button on top ? Maybe this was a mixup by previous owner? Thanks for your help everyone.

Tall one is automatic relief. Short one with button on top is manual relief.

 

[Dan Colonel]

So is it not an issue having both ? The tractor no longer has the depressor lever on cover and can be pushed around when not running.

 

[mgonitzke]

Tall one is an auto release valve; the short one is the original manual release valve. One must have gotten replaced at some point. Usually one would replace with two of the same style at least.

 

[hydroharry]

Having both styles of hydro relief valves won't change or harm operation of the tractor. It is possible it might be hard to manually push or move the tractor at one time or another since you don't have the manual release handle.

One thing I'm wondering about tho. I can't really see the front of your hydro pump in the pic you posted but I don't see the ports for a hydro lift. If you don't have them then someone has changed the pump.

 

[kharvey]

Not all 169's had hydro lift, so maybe they didn't all have ported pumps?

 

[mgonitzke]

They all had the ported pumps. The capped-off ports are visible in the picture.

 

[Dan Colonel]

Harry, I will get a different pic for you. The tractor has manual lift.
Do you want a pic from the front side looking back ?

 

[hydroharry]

Dan - yes from the front looking back. I see now that Matt said they all had ported pumps and he can see them in your picture. That's probably good enough for me since Matt knows what he's talking about, and my eyes ain't what they used to be.
