Adjusting the Hydro!

[Bill Winn 156]

Good evening, so updates on my C175:

Parking brake now works, thanks Jeff-C175.

Replacement fender pan on the way, thanks Jeff-C175 and Lincoln

New hub set screws and seals on the way, thanks elcamino/wheelhorse et al.

New rear blade tach-o-matic mount on the way.

 

So here's the issue I looked at today when I got some free time...

 

When I got this tractor I noticed that it speeds up going down hill and the speed control lever does not stay in place on its own. I have to hold it in place or it will slow down significantly.

 

Is there an adjustment on the top of the hydro? I did read through Scotty's post about his hydro woes with his 416h so it reads like I may have a compound issue.... one with the speed control remaining set and the other with the downhill acceleration. Could it be as simple as a new belt and a tightening a bolt or nut?

I've included a lettered picture of the hydro linkage on top of the unit.

Bill, do you have the Sundstrand or the Eaton tranny?

Dunno? How do I tell?

Is your filter on the right side or on the rear?

 

Also, if there's an S after the K in the model number it's a Sunny, if an E, an Eaton.

Just went out to check. It's on the rear left.

Hydros will speed up going down hill. They shouldn't get crazy fast but they do speed up. Gradually tighten up nut D.  This adjustment will regulate the  speed setting. Under no circumstances put any lubricant  on this washer assembly. Luck,JAinVA

Thanks and the VIN does have an E after the K. Is one brand better than the other?

I have 3 Eatons and they are bulletproof IMO. I know nothing about Sundstrands. Good luck

[JAinVA 4,620]

The transaxle you have is an Eaton 1100. The Sunstrand  is a good transaxle but the Eaton might be easier to find if you need to replace the one you have. Like JCM I have several Eatons and have had no issues with any of them.

And likewise my Sundstrand keeps on tickin'

 

I think they're pretty much the same reliability wise.

as suggested above - tighten nut 'D' 

 

you can also add an additional nut on top of the original nut ... (nylock or similar even better) ...

 

most (all ?) Eaton 1100 hydros will pick up speed as you head down a grade ... just tap the speed control lever lightly to reduce speed and stop the freewheeling 

Eaton 1100 hydro is very durable / reliable

Check the piece under the plate at point B. That slot in the plate will wear a groove in it throwing off the adjustment.

What Squonk said! My 515 was so worn, there was no adjustment that would last. I bought a replacement plate and adjuster but the adjuster wouldn't run in the plate without my getting a grinder on that plate all around the travel surface - the plate coating catched on the nut. Quality isn't what it once was. I adjust it while standing behind the tractor, full throttle and warm.

With the wheels OFF THE GROUND, right?

[Tuneup 1,433]

Of course not . I'm the type that has to get something in my eye before I wear safety glasses - an accident waiting to happen. I actually did just that adjustment today. The 516 did a nice job on the lawn today but the slowness of reverse is a bother. I pulled the plate and ground it a bit for more travel. You can get just a little before it hits the bracket. Put it in assumed neutral and started it at low idle. It crept forward. Nut adjust and done.

I do use jack stands and or ramps when under the Ford - have since a teen. My stupidity does have its bounds.

C'mon, give him credit. He's got it almost to the balance point so there's not much on those 4x4s. 2x4s would have been sufficient. The man must be an engineer. That's not me, though. I have my limits.

Except for the fact that they are probably Balsa Wood!

Yep, I can see the engineer now..he pushes the wrench a bit too hard, the 4x4's drop to the ground and he's left balancing the car with his hands!
