I have an 11E, serial 8878. I have a "B" manual that came with it. Can I rely on that manual for fluid capacity info or did they change between the models? Thanks as always!!! S |

Capacities are: Cooling system- 11 gallons Crankcase- 17 quarts Transmission- 27 quarts Final drive (each)-13 quarts Fuel Tank- 60 gallons Track Release (each)- 8 quarts Oil Type Engine Clutch- 17 quarts Not sure on the early hydraulic steering, though, not listed on my paper- but those systems are very small.

Thanks! I found a previous thread with a comment, from you I believe, that you used 80/90 GL5 in the finals and Trans/Hyd in the tranny, track release, clutch and steering. I read others that used gear lube in the tranny. Would 80/90 be ok in the transmission? |

| I just read this again. 17 quarts for the engine clutch? |

Yep, 17 quarts. Those transmissions are pressure lubed, so I would use trans-hydraulic.

Ok, so after having pretty good success and few nightmares on the crankcase oil change and replacing the air filter, I decided to change the tranny lube. I found that the drain plug magnets were coated with thick sludge and metal filings that included parts of the dipstick. I was a bit surprised to find only about 2 gallons of lube in the tranny. It was the expected "coffee-with-lots-of-cream" color and was mostly water. After filling with trans/hydraulic fluid, I fired up and let it run a while. I killed the engine to check for leaks and found trans fluid dripping from a drain (with no plug) to the rear and to the right of the trans drain plug. I found a matching drain hole (also with no drain plug) just to the left of this one. The right one was dripping new fluid, the left one not. I grabbed a plug from one of the finals and crawled under to put in in the dripping right drain. I then found a hole, that does not appear to be a drain, on the very back of the dozer, that oozed black goo for a while and then started to drip new fluid. This hole does not appear to have threads, so a drain plug does not seem to be possible. A picture of the back of the dozer with the dripping lube is below. I found references to the sump in my manual, but nothing that gives me much to go on. Near as I can tell the sump feeds lube to the bevel gear compartment. 1. Is there any reason why the previous owner would have pulled the 2 drain plugs? Why was only the right drain dripping? Are those drains connected? 2. Any idea why the hole in the back of the dozer exists and is dripping new fluid? Thanks for any input here!!!  |

I'm still learning the differences between the different HD11's out there, so take this with a (large) grain of salt. (I've got an 11B.) Doesn't the transmission and bevel gear case share oil? That may explain why you are seeing oil coming out of multiple locations. Make sure that all of the plugs are in for both the transmission and bevel gear case. The 11B has drain holes for the steering clutches/brakes which normally operate dry. They can be plugged and filled with solvent to clean the steering brakes. If the oil is coming from the steering clutch/brake side of the housing then there could be a seal gone where the Bevel Gear Shaft goes through the housing. Andrew P.S. On Edit: You mentioned having a manual. Do you have a parts book? I like parts books for helping to show what goes where, etc.... |

I think you are correct. I have the pdf for cleaning the steering clutches. I just checked it and it is leaking out of the right drain. That seal must be completely gone because it's still draining out of the back of the unit. A steady stream of trans/hyd fluid. Next up, figuring out how to change that seal.. (if this turns out to be the case.. |

| Will require pulling that clutch/brake assembly then the drive hub from the bevel gear spool and then the retainer with the seal, if the bearing is bad then the bevel gear will have to come out so the other side has to come down as well. |

Can't tell you what to do with your machine, but if you have to dive that far into it, I'd be seriously tempted to replace seals and bearings on both sides of the bevel gear shaft.... Andrew |

I added a half gallon of Lucas seal softener to the trans and added back 2 more gallons of lube and after about 5 minutes of driving the previously-dead trans pressure gauge came alive. The leak appears to have gone from a gusher down to a slow drip. Keeping our fingers crossed. I have hydraulic tilt on the blade. Does anyone know how how much fluid the blade hydraulics hold? My manual doesn't mention it. |

| I'm still unsure about using trans/hydraulic in my HD11 manual tranny.. but SAE 50 tranny fluid is very expensive. |
