Hy-Tran Fluid Question

[yingpin]

So I have been getting ready to do some maintenance on my 124 and was going to change the gear oil before I add all the parts for the sleeve hitch and adapter.

So in a gear drive unit, Hy Tran or SAE-30 can work but you guys prefer Hy Tran....Since I have never done this to a tractor and dont know the history of it. Would you recommend a simple drain and fill or remove the back off of the gear box, clean, use gasket sealer and replace?

Not knowing the history, and for the sake of argument, use Hy-Tran, remove the back off the gear box, drain, clean it out, look at the gears for missing teeth or chipped teeth, buy a gasket.... repeat buy a gasket for the rear cover then bolt cover back on. Fill with hy Tran.

Thanks for the reply. I will go up to TSC to get the fluid. Dumb question, where does one get a gasket specifically for the 124 or this style or tractor?

The gear drive unit in your tractor is essentially a combination of a manual car transmission and a car differential (rear end) except they don't turn as fast. So literally any fluid that lubricates will work just fine. Personally, I like the 20w50 that they us in motorcycle transmissions. If it's good enough for a 100 mph motorcycle, it'll work in a Cub.

On draining and cleaning, they may exist but I personally have not seen a narrow or wide frame Cub with a transmission drain plug. So your only option is to remove the rear cover to drain the oil. So I guess clean it if it needs it.

Less than $5 qt @ Wally World.

A couple of ways. First, part number is IH-350837-R3. You can go to a cub cadet dealer and order one. Unless they have one in stock, which would be nice. Or, there are vendors out there, like on top of this page will have them. Finally, partstree.com can help you a lot with part numbers and you can order thru them too.

Is this not the drain plug for the transmission? The manual I found indicates there is one

[IHscout79]

You are one of the lucky one’s! That’s a drain plug. However, since you don’t know the history of this machine, if it was mine, I would take the rear cover off and drain it from there and look inside there, and clean it out with a rag and/or paper towel if needed. You might be surprised how much ‘sludge’ might be in there. Just my opinion.

It sure does look like one, but I agree with opening it up and cleaning it out.
As far as the gasket goes, it would be very easy to make your own from a roll of gasket material the you can buy at TSC or an auto parts store. Another option is RTV gasket maker....

Some time in mid March I have every intention of filling a 106 and 149 with the cheapest RK brand hydraulic fluid on the shelf at $16.99/5 gallon, and using RTV for a gasket on both. I'll keep you posted.

Took off the rear end and cleaned it out. Everything looks pretty good in there, all teeth accounted for and not too sludgy. Decided to paint the rear as it was looking dirty and fsded. Drain plug was a nice feature as well. TSC did not have any Hy-Tran so I will use the SAE -30 I had on hand once the gasket cures.

I am trying to get the sleeve hitch installed but there is no room to slide the bar while attached to the bracket as it states there should be in the directions? It is tight all up under there and pretty filthy.
