edca Posted August 31 Share Posted August 31 Hello everyone, any help would be appreciated. I have an issue with my td8e. I got this machine not long ago. The engine had to be replaced which I did replace. Then the engine that I bought to replace the old engine with had a blown head gasket. I replaced the head gasket and the engine seems to be running just fine. Before I had to replace the head gasket I managed to drive this machine and it seems ok to me. The machine had lots of power to push dirt. But, the clutch pressure gauge was going over the green area to around 3 o'clock. I cleaned the suction screen filter and it was very dirty, I also replaced the transmission oil filter in the battery compartment. Now, when I start the machine it moves very slow until it stops. It seems to me that after shifting the trans back and forth with high RPMs and it gets warmer the trans starts to work and I can push dirt again but it still seems to me that it should have more power. I really appreciate any help. Cheers! Quote Link to comment Share on other sites More sharing options...
edca Posted September 3 Author Share Posted September 3 Hi again, any help is very much appreciated. I have been troubleshooting my td8e and decided to get some dish soap in water and made lots of bubbles to test for suction leaks. I did not fine any suction leaks through any hoses or connections. Now, the breather on this transmission was taken off and replaced by a long open hose. I noticed that when I get the rpms high and I put the soap bubbles against the hose the hose sucks the bubbles really fast. I guess my question is, should this hose be sucking air? If the breather was install would it be sucking air? Does anybody knows where I could get a transmission breather for this td8e? Thank you in advance for any help.

Dirt_Floor_Poor Posted September 4 Share Posted September 4 I don’t know much about an 8E. Is this a power shift? If it is and shifting back and forth seems to help, it sounds possibly like worn splines in a clutch pack that are hanging up. I can’t think of anyone on here who has that model and unfortunately there are less and less mechanics who were intimately involved with these machines all the time. Maybe someone else will chime in. Dressta dealers are who handle whatever parts are available. Quote Link to comment Share on other sites More sharing options...
louie figone Posted September 4 Share Posted September 4 edca, can you take a picture of the hose in question, is the hose in question on the transmission or the torque converter? These power shift tractors need to have the transmission oil warm to work properly, they also need full throttle when operating. Quote Link to comment Share on other sites More sharing options...
edca Posted September 5 Author Share Posted September 5 Thanks for the replies. After what Louie said, I did notice that when I am using full rpms it definitely runs much much better. I was not sure if it was safe to operate at full throttle. The last time I ran it, after it warmed up for about 15 minutes I used full throttle for about 5 minutes and it moved real nice. Then I lower it to one tooth down and it seems to move a bid better than before. So, it seems that the warmer the oil gets the less rpms it needs to run. But it does move better at full throttle. Does that make sense? Should I really be operating this crawler at the very top full throttle available? About the hose, it is where the transmission breather is supposed to be connected to. The previous owner took the breather out and installed a hose. Another source told me that the hose will actually do the same work as the breather except that breather usually has some wool in it that acts as an element filter. The hose will let some dirt to come in the trans oil but the function is the same. Thanks again for all the help. Cheers! Quote Link to comment Share on other sites More sharing options...
Dirt_Floor_Poor Posted September 5 Share Posted September 5 Yes, it should be operated at full throttle. That is how it is designed and it is necessary. Get some hearing protection and open it up. Quote Link to comment Share on other sites More sharing options...
louie figone Posted September 5 Share Posted September 5 edca, Put a breather vent in place of that hose, it will keep dirt out of the transmission, also check to see if there is a breather on the torque converter, the C series has them, IH or Dresser may have done away with the torque converter breather with the later series, the breather for the torque converter is located on the right side behind the engine in front of the dash, you can see it below the air filter. These tractors have a torque converter (fluid coupling), they need full rpm to transmit the power to the transmission. Quote Link to comment Share on other sites More sharing options...
edca Posted September 5 Author Share Posted September 5 Ok great! This might be just pure ignorance from my part. Yes, that is the breather I am talking about. I thought it was the transmission breather but according to the manual is a torque converter breather. There is a hose replacing the breather. I will try to install a proper breather in there. I guess the next thing for me to do is to wear some good hearing protection and drive the machine in top full throttle and see what happens. Thank you all for all the help. Cheers!

R.D.G Posted November 7 Share Posted November 7 What grade of trans oil in it, IH always ran 10w in their transmissions. A cold climate and wrong old will make it sluggish till it warms up. Quote Link to comment Share on other sites More sharing options...
