Dresser 175c

I have a dresser 175c. Great machine. Recently it stalled when I was cresting the climb out of a foundation excavation. As soon as the machine dropped down to level ground (normal tip- like on the fulcrum of a sew saw), it stalled. Tried to restart, starter was spinning but not engaging the flywheel teeth. Pulled out starter (24v), and had it rebuilt. Note- approx 2 gallons of oil drained out from the transmission housing where it mounts to. Is this normal?

I installed rebuilt starter & ran machine for a few minutes, let it idle, then noticed oil pouring out from area around starter. Took it out again, brought it back to guy who rebuilt it. He took it apart and oil was inside the starter and inside the solenoid. He let it drain, dried it, and replaced all the seals again.

Reinstalled it again, ran the machine, everything was good. Stopped machine and about 5 mins later noticed oil dripping out from electrical end of starter again.

What could this be?
 
Sounds like you could have a bad seal somewhere but there is also such a thing as a wet starter. My 931B Cat has one. It means there's oil behind the starter but the starter will have seals in it to keep the oil out of it. Is there a gasket where the starter bolts on? Did the guy that rebuilt it use the right seals? Someone more familiar with your machine should know more. Dave
 


Thanks Dave, i think you are right, someone told me it is a wet starter - there is a gasket where the starter bolts on.

This gets real sticky quick.. First IF you took the starter to a regular automitive place they probably did not put the seal in between the electrical part and the drive end. That is the first place.. Next is a stoped up drain line from the torque. the right side of the bell housing has a drain and as the flywheel turns it is supposed to force the waste oil from the torque back to the transmission. If that line down the right side is restricted what you have will happen.. Then las of all is the seal is blown in the torque hub (called jeus rings) and you are just putting more oin in the outer tourq housing than can get back so it is going in the starter. Setting on lev el a normal won will run out no more than about 1/2 gal of oil when starter is removed. In my years I have seen many 15c dozers and 175 c loaders catch fire from what you are experiencing ... so get it taken care of quick. 1 ..check starter fro right seal 2 check big line going down right lower part of machine . 3 check torque converter for blown internal seal.
 
my partner says this guy who rebuilt the starter has experience and has rebuilt these 24v starters before...

Thanks JM.... so this drain line goes from the bellhousing and leads to the transmission? its on the right side ( when sitting in driver's seat) ?

Do I disconnect from the bellhousing end? How much oil will come out? To test that it is not restricted, do i run the engine for a few seconds and see if oil comes out?
 
You will find it almost impossible to take the line off in the tractor. Yes it does go to the bell housing directly opsite the starter..Usually the only thing that happens is mud builds up in the belly pan and causes the hose to get mashed or flow restricted. If every thing looks good that is probably not the problem. You can find that hose and follow it back where it stops and remove it then take air hose and blow. Listen for the air to come out.
sometimes there will be something get in that place where the hose fastens on the bell housing.
I am betting you have hub rings down in the torque..right on top of the torque is a 6 boldt plate I have pulled this plate and replaced with peice of plexglass where I could see how bad the torque was passing. IF you have to go in the torque be carefull lots of shops do not know the 175c loader and the 15 c dozer look identical and will fit but the internal parts are diffrent. The loader has a lower stall speed so when you get to the bank engine will reve up and loader perform without stalling the engine.
