Gearmatic specialists, hydraulics?

I havent really kept up with your winch controller plans because i dont know enough about forestry winch internals to not put my foot in my mouth, and your plans are complex enough to confuse me so i cant really be much use.  

But i thought you might be able to make good use of vektek, enerpac and vickers manual control valves for machine fixturing.  Theyre the perfect size for low volume hydraulic controllers with manual levers which are simple, reliable and allow some modulation.  Solenoid valves i consider less reliable than hand operated spool or rotary valving. 


There are tons of these sold on ebay and other MRO surplus sites.  They make many configurations.

Thanks a lot Mike, for the reply. 
Well, it simple, as i see it.  (now) 
There is one clutch cylinder
and one brake cylinder. 
For freespooling of the drum, only the brake needs to have pressure. 
For winching in (or out, i will have that option) 
Both of these need to receive pressure to open. 
I will use two solenoid valves, because i really really want a remote. I wouldn't have bought the gearmatic otherwise. I knew i could do it. 
Both will be actuated by relays.  (we call those "contacteurs") 



 
I have plenty of those, in 24v, from the chairlift company. 
One switching only the brake solenoid valve.  
The other one switching both valves. One single switch on the dashboard,  
Middle position braking. 
One "retained position" for the freespool. 
One, that i have to hold, for the winching in. 
And all of this paralleled with the remote. 
I wonder if it is worth anything to have the freespool on the remote. 
Motor start and stop would be nice.

 When you have the remote on, working the brake release that's when you will have free spool. The way you have it worded it should work perfectly.

[Satamax]

Thanks ED. Only prob, will be buying cetop 3 Nothing much, 150€ of solenoid valves. 70 or so of remote. I need to sort out what kind of hydraulics i want.  How i implement things. 

[mike_belben]

In america we call them contactors also.  Sounds like youve got it licked max. 

[Satamax]

Well, i discovered something. The o ring on the drum side of the clutch and brake compartment is gone!  :
Anybody knows the joint's diameter and circumference of the drum's seal? 

[Ed_K]

 I looked all thru my book and all I can do to help is the large o-ring is part # 50347 and the smaller one is part # 50331. These are on the model 19.

[Satamax]

Thanks a lot Ed.

I have G281 as a number for this O ring.

I would like to know the dimensions, to glue one myself! I'll glue it on the drum, oil it then push it in.  Instead of taking everything appart! 

[Satamax]

The drum's O ring being missing bugs me big time.

Anybody here has changed his?

And there is the worn out and bent splines on the shaft, which annoy me too.

 

[mike_belben]

In the american southeast that is a highly technical condition known as 'wallered out.'

'Snawt good. 

[Satamax]

I had to look at the "translation" well, that's after a lot of translation! :D  ;D

[Satamax]

Guys, it's chtuck!

Is there a trick to get those out ? 



 

[Satamax]

It's doing my head in.

I have a part number on the housing D-1.9534, which leads to nowhere, but may be caterpillar. Looked cat adapter plates.

And it seems there is a # 21 or 15 bolt. Which i can't see how to unscrew.

It doesn't look like this one either.

There is the bolt on this one

https://avspare.com/catalog/case/57194/5647562/843361/

and this one too.

[mike_belben]

Cant help ya there max.  Any chance its hung on that center shaft or maybe snap-ringed from the interior?

[Satamax]

I don't know. I just turned a bolt chaser out of some brass. And pushed the four remaining bolts out. To no avail.

[Satamax]

So finally, it is all appart. 

The two hidden screws were in the two big holes of the rear mounting stubs. 

16 mm hex head, or 5/8" I ground a 17 mm one. 









I still need to remove the oil seal. 

Work on the input shaft, which has a good 2 mm runout. 

I will cut the splines out. Buy a proper shaft, 21 splines 1" 3/8. Bore it to the right diameter, bar a few thousandths.  Heat shrink it on the shaft, weld it to it. Then dress the welds. Redo the oil seal "journal" I have a bit of room there. I think i can do something. Or sleeve it. 

I have discovered that the brake doesn't hold, while lifting the winch to turn it over. I will need to change the input  gear bearing too. 

Lotsa work ahead!

 That back plate doesn't look anything like my 19, did you figure out what it is? I don't have a hydro access like that.

Ed, sorry, i don't know what it is. May be some caterpillar. The number seems to lead that way. 
What do you mean by "hydro access" ? 

[Ed_K]

 On the left side of the plate there's what looks like a cat hydraulic bolt up for a hose.

[Satamax]

Sorry to be dumb. I don't see what you mean. 

[Ed_K]

 I went back to reply 87 and I'm wrong, what i was looking at are just mounting brackets. Sorry for the confusion :(.
