Hagen transmission

[riotwarrior]

Well I've been searching for a long time on info and the patent located in threads here have helped me more fully understand the Hagen transmission.

TRANSMISSION SYSTEM

Now what I'm able to determine thus far from reading and testing, is the hydraulic control component of the transmissions function is entirely independent of the gears and function within the case. Two systems combined to make one functioning transmission.

Also the PTO input be it CW or CCW does not matter as you just swap upper and lower hydraulic hoses on each side to make the controls function as desired.

That the Annular piston that controls the clutches can be adjusted for internal clearances and lets say should be 0.039"-0.045" clearance from what I can tell from testing.

There are two return springs for each clutch piston to keep the unit in the neutral position when controls released.

What I'm not able to figure out except for a guess, based on one image of a yellow ridge runners engine cover, is that it used ATF for fluid in the transmission. I saw a NAPA ATF bottle in a picture of a Ridge runner one day and subsequently felt that's what it uses.

Does anyone know what fluid the transmission utilizes?

[riotwarrior]

BUMP....

Anyone...???

I'm running ATF but if something is specific I'd like to know

I ran ACDelco Auto-Trak II in mine. No problems but not really used that much.

What was it in? Do you have any info besides the patent that's out there on them? I've reset my clutches to 0.075" clearance and it seems to build a bit less heat now.

I'm trying to find as much info as possible and any help what ever it is would be fantastic!

TY

Hi Keith,

Read that and took it all in big time. Love the dohnuts in snow...I do em in gravel LOL spins like a MOFO for sure...better n any Carnival ride for sure LOL

Have you done any changes to the settings on your unit? Does it have a breather of some type for the case? I'm having some mild issues with heat buildup and subsequently causing oil to expand and then piss out some seals.

Also what level do you fill yours too?

Clearly I am in need of details not yet found LOL

Thanks for any help at all...

Oh and heard today this is also referred to as a rooter transmission or router don't know what way they spell it but sounded like the first one rooter...??? Know anything about that?

je Vien de d découvrir la transmission HAGEN ,je pense que c est très bien .il Ya la T20 qui semble merveilleuse .quel est la meilleure.

Le Hagen est cool parce que vous pouvez inverser un côté tandis que l'autre est en avant. C'est un FRIM de changement en douceur vers l'avant à l'arrière. Suppose aussi d'être forte. T20 est un grand transmission trop.

I made no changes to the setting however the right side does have a slightly different feel than the left lever. My Hagen had a breather on the left side. I filled it to the center fill plug which was about a quart if I remember correctly. Hope that helps. Keith.

Can you please provide some detailed images of said breather?

I have been somewhat into mine of late, I removed one of the annular pistons to check if I could remove clutches or not.

So far no luck I've got to split my case to get at the clutches

I've got a slightly different feel on one side compared to the other too, my LH side seems to drive forward more than the right or the right slips more when fully engaged in forward direction. My leavers do not LOCK they have to be pushed forward constantly.

Here are some pics of it disassembled as I've said.

First this decal was made up just for me and the machine! LOL


Now onto the clutches and transmission shots, here is the bearing cap, and lock nut holding shaft in place and annular piston in place


Once you remove the cap and big nut, and six retaining Allen head bolts, you remove the annular piston by pushing on the control leaver forcing it outward which then slides out as you can see here


The torrington bearing in that first pic actually rides against the piston on the dark ring


There is a gear as seen here inside the transmission, it's what the small swash plate rides against, and the bearing then the piston


Removed that gear and this is what it looks like


After that you can clearly see the clutch packs inside and NO I cannot access them at all sadly.



After all this a little cleaning and some reassembly and I was done with my investigation.

However I did do a small video of the function of the annular piston!

Here is the video or a link to it LOL
Hagen Transmission clutches and annular piston function - YouTube

That's what I've gotten so far, now I've gotta work on some clutches for the Kubota

Spoke to a fellow who says a Commet 780 Primary clutch and 860 Secondary clutch would work well the 780 with a green spring set for 1075 RPM egagement.

Nuff for now on this Hagen!

I split one of my Hagens today. Other one is still in the machine but I haven't been able to get it to work. I need to figure out how to bleed the control valves and lines going to the annular pistons. Im using controls from a ridge runner for testing and att fluid in the Hagen as well as the control valves. The inside of the Hagen is simple. Clutch packs and gears. Any suggestions on bleeding controls or recommended fluid?

[riotwarrior]

firzt things first.

i would be interested in aquiring one of your hagens if that is a possibility. PM me if it is I want to build an 8x8 with one.

second

are you abzolutely certain the controls are in good working order?

third

seeing as this is not bleeding brakes grease on bleeder threads to seal is acceptable.

I use a 9 litre vacuum pump to draw fluid through system attached to bleeder nipples. Any vacuum bleeder would suffice.

once I pass plenty of fluid I tighten down bleeder and test for operation.

as my controls are slightly different than yours I dont know if you can pump bleed with yours.

I cqn with mine but what a pita.

it takes time and effort but once done its great stuff.

good luck with it please post pics and feel free to ask questions.

pm me I will provide my cell no we can talk on phone and work through details.

Riot-
Well, I finally got things working. My Trailblazer is alive. The Ridge Runner controls loop the hose from the reservoir to the cylinders in an upward fashion. I had an air bubble trapped in the top of the loop. No vac to pull it through, just had to disconnect it and let it flow. I've still got the other Hagen apart. Yours looks perfect inside. I ended up using atf in my trans and controls. As its cold here and I've only put a couple miles on the machine so far, I've no idea about heat buildup. I can take pics and send them to you if you'd like. I'll pm you my number.

[tribaker]

I have a Ridge Runner Trail Boss with a Hagen Transmission w/ JLO 440.

I believe the engine might be junk.

Looking at putting a two cylinder diesel in it. How difficult will this be?

I have attached a few photos.





thanks
