Dresser 125e transmission help


Recommended Posts

I think the adjustments of the bolt and jam nut are on top of the final drives for each side

I see where it adjusts. I am just not sure how to adjust it. I always thought you lightly tightened them then backed off a quarter but the manual says to stick a 3/4" wrench somewhere to keep it from going to far? Doesn't make sense to me.

 

I have replaced several hoses on this thing. I am trying to find out where I check the transmission pressures. My manual is a recopy and the photo in it is horrible. I think it is on the left side of the transmission towards the top. I see a compucheck fitting and several pipe plugs, I am assuming that is where they are checked but I am not sure. I am going to mess with it more tomorrow.

watch at 24 mins on should be similar to yours for steering and brakes adjustment

I'm at a loss with E's but here is what I know. If it has the bolt/lock nut on each side of the rear case that would be the pivot brake adjustment, start unit and pull levers back, if one goes farther then the other tighten the bolt on the one that pulls back the farthest to equal them out, if looking for more brake I wouldn't adjust more then a full turn on either. If it has a block with maybe 3, 1/4in lines and caps that's where you check pressure, no idea of which ones which and need a manual for that and what pressure. With the E's you need to check pressure in the final drive inside the rear case and I have no idea on that.

This is what mY manual shows for checking pressures. I can’t make anything of it. I did find several pipe plugs on what I think is the regulator valve. I hooked. My gauge into the one with the compucheck fitting. It showed around 40 PSI. There looks to be a check valve here as it’s threaded into A large nut. I see a line going to the gauge so I assume that’s clutch pressure. No idea on the others

Poncho, checking transmission pressures is not hard to do, here is a blown-up picture of the regulator valve, you check the pressures at the ports with plugs, port 1, port 5 and port 4. To know what the pressures should be is located on the next page of the page that shows the regulator valve. I have attached the page here, also attached are the pressures I recorded on my 100C, all within recommended range.

Thanks for the info I really appreciate it. It looks like your is different than me mine. My regulator valve is pictured (at least I think that’s it.). I see a lot of plugs in it but not sure which is which

 

maybe it’s the wrong valve I’m looking at. This is on the top Left of the transmission. My transmission is the small transmission. I’m not sure if it’s the same as the c? 
 

 

thsnks a lot for taking the time to Reply

Im Not at the machine right now but mine is the small transmission with about a 10-12” driveshaft. I have the torque converter then the transmission is back under the seat. Mine has the single dipstick/ fill port. One thing I did notice I forgot to mention is when I drained the torque converter not much fluid came out, maybe 3 quarts. Not sure how much it should hold

I did check some pressures. One I know is clutch pressure. It is showing 250 PSI.  I put it in another port above the clutch pressure gauge port. I showed around 250 in 1st gear forward and backwards. 0 in 2 and 3 gears. I checked another one close by my lube pressure, it was 0 as well. The lube pressure is around 25. 
 

Mine is different than Louie’s. My manual shows one like his. But my ports are different. He says his regulator valve is between the decelerate and brake pedal. Mine is on the left side of the transmission by the seat. 
 

I guess best thing to do is order a manual for 1986. Mine shows to be for all Models but it’s not

I did find this online. Exactly like mine. I see the ports are numbered but it doesn’t say what they are

For some reason, not sure why, but my books that say they service 100/125 c and e loaders, as well as td 7 and 8, c and e,  have the exact same pics and procedures as shown above, clearly yours is mounted on the side as apposed to top like the 8s, I get a chance, I will pull my floor, see what I have

Here's pics of my 8 e, it's like the books show, 

I had a hose to replace, and no way to power wash, but you can see the test ports are on top. Sorry, not much help I know, good luck would a European machine be different configuration perhaps ?

The late E model TD8's and 125's have a different transmission than the earlier ones.  I think s/n 9500 is the break.  Poncho's fits in the late group.  Sorry I can not remember which port is which, been too long ago.

Yes this is different than mine. Mine doesn’t have the torque converter dipstick either. My clutch pressure stays at 250 in all gears forward and reverse. When I do shift it it will drop to 100 for a second then back to 250. My lube pressure stays around 25. 
 

im really starting to think mine is a steering system issue. When I engage the left lever it doesn’t want to turn. The right one turns better. It will pivot with the right lever. If I pull both levers back and leave it at hi idle the machine stops. After i Release the levers it seems to respond better. I’m thinking I’m losing pressure in the steering

well I fixed the Dresser 125e today. A mechanic from Tennessee told me how to. What I did was pull the counterweight(fun to put back on!), removed the little cover that is six bolts, and adjusted my steering clutches. There is a little keeper on mine you remove and then you can turn the adjusting bolt in. it pushes good now and pivots well.  i knocked out a 20' tall compost pile today with.     these are great machines

Here is the filters. The fluid looks bad too. Milky. I Seen some brass in the strainer. Not go much but any is bad. I figure the brass is out of the transmission. I had to order the filter. Won’t be able to try it for a few days.

Hi Poncho..  I have the same setup on my Late 1982 SN: 9512 125E. I am looking to find this Trans Oil Strainer per your pics & your showing a strainer & filter above. You mentioned the Trans filter using Wix 51181. 

When I look up the Wix#, its a steel filter. So is it a 1 piece (strainer + filter) replacement or is the Wix# just the filter that fits inside the strainer? The original part# from my book for this = 622 255 C1

Lastly, do you happen to also have the item below & have you serviced or replaced it? IF anyone watching this thread has a part# for this as well, it would be appreciated as its called out in the service manual, but cant find the original part# in my books let alone cross ref to new part# anywhere.

Transmission System Suction Filter - 
(Located right side under floor pans) - Service Only, no replace unless damaged

I have not pulled mine yet just in case something is needing to be replaced, I like to have the parts in advance.

Thanks & Regards
